Description

  The present invention relates to a bookbinding sheet used for bookbinding.

  A bookbinding sheet is already known in which a hot-melt adhesive layer that melts by heating and exhibits adhesiveness is provided on one surface of a tape-like substrate (see, for example, Patent Document 1). For example, the bookbinding sheet is attached so as to wrap the ends of a plurality of pages of paper sheets to be bound, and then heated to a temperature equal to or higher than the melting point at which the hot melt adhesive layer melts. Accordingly, the bookbinding sheet fixes the plurality of pages of paper sheets as a back cover by the adhesiveness of the hot melt adhesive layer developed by the melting.

  In this prior art, at the time of manufacturing a bookbinding sheet, the base material is fed out from a roll wound with a tape-shaped base material (tape base material) and is transported horizontally. Then, a liquid hot melt adhesive is ejected from the nozzle above the substrate conveyance path. Thereby, a hot-melt-adhesive layer is formed on a base material layer by apply | coating a hot-melt-adhesive with respect to the said base material conveyed horizontally, and cooling after that.

  However, the above-described conventional technique is a method in which a hot melt adhesive is simply applied from above to a substrate to be conveyed. As a result, it is inevitable that irregularities are generated on the surface of the hot melt adhesive layer formed on the base material layer, and it is difficult to smooth the surface of the hot melt adhesive layer. As a result, for example, when a bookbinding sheet is transported in an appropriate processing apparatus that performs bookbinding processing or preparation processing therefor, smooth conveyance may be difficult due to the presence of the irregularities on the surface of the hot melt adhesive layer. there were. For example, when printing is performed on the side of the substrate opposite to the hot-melt adhesive layer in the processing apparatus, the presence of the irregularities may cause blurring and the like, leading to a decrease in print quality.

  An object of the present invention is to provide a bookbinding sheet that can be smoothly conveyed at the time of manufacture and can perform printing with good quality.

In order to achieve the above object, the present invention provides a bookbinding sheet having a dimension in the thickness direction, the base sheet being provided on one side in the thickness direction of the base material layer, and the base material A temperature equal to or higher than a predetermined melting point applied to a layer or a material layer provided adjacent to one side of the base material layer in the thickness direction so that the surface roughness is within a predetermined range.

  The bookbinding sheet of the present invention is used for bookbinding. For example, it is attached so as to wrap the ends of a plurality of pages of paper sheets to be bound, and the plurality of pages of paper sheets are fixed as a back cover. Therefore, the bookbinding sheet of the present invention is provided with a hot melt adhesive layer. Since the hot melt can be melted at a temperature equal to or higher than a predetermined melting point to exhibit adhesiveness, by setting the temperature equal to or higher than the melting point at the time of bookbinding, the plurality of pages of paper can be fixed by the adhesiveness. . At this time, a printing area is provided on the side of the base material layer opposite to the hot melt. Thereby, a desired description (title, manufacturer (author), date, etc.) can be displayed by forming a desired print on the side opposite to the side on which the paper is fixed.

  And in the sheet | seat for bookbinding of this invention, the hot-melt-adhesion layer is formed so that the surface may become smooth in a base material layer (or to-be-coated material provided adjacent to the base material layer). Therefore, when the substrate layer provided with the hot melt adhesive layer is transported in an appropriate processing apparatus that performs bookbinding processing, preparation processing therefor, etc., compared to the case where irregularities exist on the surface of the hot melt adhesive layer, It can be transported easily and smoothly. In addition, when printing is performed on a print area by thermal transfer from an ink ribbon in the processing apparatus, it is possible to form a print with good quality without blurring.

It is done.

<Configuration of printing device>
FIG. 2 shows a printing apparatus 1 (corresponding to an example of a processing apparatus) that prints on the print-receiving tape 100 using the printing tape roll TR1 and creates the spine cover sheet L. In the printing apparatus 1 shown in FIG. 2, a character input dial 4 that can be operated movably is provided on the upper surface of the main body 2. Adjacent to the character input dial 4, a function key 10 for performing various controls of the printing apparatus 1 such as a power switch 6 and a print key 8, and a liquid crystal display (LCD) 12 for displaying inputted characters and symbols. And are provided.

  As shown in FIGS. 3 and 4, a cassette holder 80 is provided on the back surface of the main body 2, and a tape cassette 70 (corresponding to a bookbinding tape cassette) can be attached to and detached from the cassette holder 80. The main body 2 has a tape feed drive shaft 50 fitted to the tape feed roller 36 in the tape cassette 70 when a cartridge housing 70a (corresponding to the housing) of the tape cassette 70 is mounted on the cassette holder 80; A ribbon take-up spool shaft 52 that is fitted to the ribbon take-up roll IR2 in the tape cassette 70 is provided, and is driven by a pulse motor (not shown).

  As shown in FIG. 4, the cartridge casing 70a of the tape cassette 70 is provided with a printing spool 18 (corresponding to a winding member) that is rotatable about an axis k. On the outer periphery of the printing spool 18, a bookbinding tape roll TR1 is formed by winding the print-receiving tape 100 with the hot melt adhesive layer 101b on the outside (originally a spiral shape but simplified. It is shown as a concentric circle). In the tape 100 to be printed, the hot melt adhesive layer 101b is provided on one side in the thickness direction of the base material layer 101a as described above, and the transfer layer 101c is provided on the other side in the thickness direction of the base material layer 101a. It has a three-layer structure.

A movable platen roller 58 and a driving roller 60 are rotatably held by a roller holder 56 that is rotatably supported by a swing shaft 54 fixed to the main body 2. Then, by operating a roller release lever 62 (see FIG. 3) that swings the roller holder 56 around the swing shaft 54, the movable platen roller 58 and the drive roller 60 enter from the roller entrance 34. At the time of entering, the print-receiving tape 100 exposed at the roller entrance 34 and the ink ribbon 26 are overlapped and sandwiched between the heating element 49 of the thermal head 48. On the other hand, on the downstream side, the print-receiving tape 100 is sandwiched between the drive roller 60 and the tape feed roller 36.

  When the tape feed roller 36 (corresponding to the transport roller) is driven in the state taught as described above, the print-receiving tape 100 is transported from the print tape spool 18 to the roller entrance 34 via the guide shaft 32. Then, it passes through the slit under the tape retainer 23 and is discharged to the outside of the cartridge housing 70a.

  At this time, the ink ribbon 26 formed by applying heat-meltable ink to the base film is wound around the ribbon supply spool 28 with the ink surface facing inward to form the ribbon supply roll IR1. The ink ribbon 26 passes from the ribbon supply spool 28 between the print-receiving tape 100 and the guide shaft 32 and is superposed on the print-receiving tape 100. Here, a thermal head insertion hole 47 surrounded by the ink ribbon 26 and the peripheral wall portion 46 is formed in the inner side of the roller entrance 34. The thermal head 48 attached to the main body 2 is inserted into the thermal head insertion hole 47. At the tip of the thermal head 48, the heating elements 49 are arranged in a line perpendicular to the feeding direction of the ink ribbon 26. The transfer layer 101c of the print-receiving tape 100 is composed of a transfer-receiving material, and is transferred by thermal transfer from the ink ribbon 26 by being heated by the heating element 49 of the thermal head 48 in the above-described superimposed state. A print is formed on the layer 101c. The melting point of the ink ribbon 26 at the time of the thermal transfer is, for example, higher than 150 ° C. and 200 ° C. or lower (preferably 160 ° C. or higher and 200 ° C. or lower). After the printing is formed by the transfer, the ink ribbon 26 reaches the roller entrance 34, and the traveling direction of the ink ribbon 26 is rotated by about 180 ° via the peeling plate 40, and is wound around the ribbon take-up roll IR2. The peeling plate 40 is fixed at a position separated by a predetermined amount on the downstream side in the traveling direction of the ink ribbon 26 from a heating element 49 of the thermal head 48 described later, and peels the ink ribbon 26 from the print-receiving tape 100.

  A cutting lever 64 and a rotating cutter 66 that rotates in conjunction with the swinging of the cutting lever 64 are provided downstream of the drive roller 60. A flat cutting blade receiving portion 81 that receives the cutting blade 66 a of the rotary cutter 66 is provided in the tape cassette 70.

<Printer operation>
In the printing apparatus 1 configured as described above, an operator inputs a desired character, symbol, or the like through the character input dial 4 or the function key group 10 and presses the print key 8. Then, while the print-receiving tape 100 and the ink ribbon 26 are fed at a predetermined speed, the heating element 49 of the thermal head 48 generates heat based on the input data such as characters and symbols. As a result, characters, symbols, and the like are printed on the transfer layer 101 c of the print-receiving tape 100, and then discharged to the outside of the printing apparatus 1 by the driving roller 60. Thereafter, when the operator operates the cutting lever 64, the rotary cutter 66 is rotated in the direction of the arrow in FIG. A sheet L is generated.

<Back cover sheet>
An example of the spine cover sheet L generated as described above is shown in FIGS. 5 (a) and 5 (b). The spine cover sheet L generated using the print-receiving tape 100 as described above includes the base material layer 101a, the hot-melt adhesive layer 101b, and the transfer layer 101c. Since the hot melt adhesive layer 101b can be melted at a temperature equal to or higher than a predetermined melting point to exhibit adhesiveness, by setting the temperature equal to or higher than the melting point, a plurality of pages of paper are fixed by the adhesiveness at the time of bookbinding. (The details of the bookbinding procedure will be described later). As shown in FIG. 5B, the transfer layer 101c is provided on the side of the base material layer 101a opposite to the hot melt adhesive layer 101b. As a result, a desired printed item R (for example, text “Presentation file No. 1” in FIG. 5A, for example) is formed on the side opposite to the side on which the above-mentioned paper is fixed. Title, manufacturer, author, date, etc.) can be displayed.

<Bookbinding procedure>
Next, a bookbinding procedure using the spine cover sheet L created as described above will be described with reference to FIGS. In the present embodiment, bookbinding is performed by the bookbinding apparatus 120 including the bottom heater 56.

  In the bookbinding apparatus 120 shown in FIG. 6, a clamp member 53 and a bottom heater 56 are provided. The bottom heater 56 has a back heater 56a for heating the spine sheet L. Further, side heaters 51 and 52 are provided on both sides of the bottom heater 56. The side heaters 51 and 52 have heaters 5la and 52a and rollers 5lb and 52b, respectively. Further, tape guides 86 and 87 are provided in the vicinity of the side heaters 51 and 52, respectively, and these tape guides 86 and 87 are rotatable around support shafts 88 and 89 to which the base portions are fixed. ing.

  First, the sheet S to be bound is clamped in the thickness direction (upper right to lower left in FIG. 6) by the clamp member 53 while being guided by the regulation guides 90a and 90b, and is bundled. At this time, the spine cover sheet L is bent into a substantially inverted C shape with the hot melt adhesive layer 101 b side inside, and is held by the bottom heater 56. The clamp member 53 that clamps the paper sheet S linearly moves to the lower right side in FIG. 6 along the surface direction of the spine sheet L, and thereby the rear side end portion (the lower right lower end in FIG. 6) of the paper sheet S. ) Is brought into contact with the spine cover sheet L having a substantially inverted C shape (state shown in FIG. 6). When the paper sheet S comes into contact with the spine sheet L, heating by the back heater 56a of the bottom heater 56 is started. Thereby, the hot-melt adhesive layer 101b of the spine cover sheet L is melted, and the binding of the rear end portion of the paper-like S is executed.

  When the rear surface binding of the paper sheet S is completed, as shown in FIG. 6, the side heaters 51 and 52 lift the both ends of the above-mentioned reverse C-shape of the spine cover sheet L while the spine cover sheet L side. Move to. Further, heating by the heaters 51a and 52a of the side heaters 51 and 52 is started. As a result, the hot-melt adhesive layer 101b is melted while the back-side edge of the paper sheet S is pressed through the spine sheet L, so that side binding is started. At this time, the regulation guides 86 and 87 are retracted in the direction away from the spine sheet L as the side heaters 51 and 52 are moved. Then, as shown in FIG. 7, the side heaters 51 and 52 are brought into close contact with the spine sheet L by movement, and the binding of the side surfaces of the spine sheet L is completed.

  Then, as shown in FIG. 8, the side heaters 51 and 52 are moved away from the spine sheet L, so that the pressurization by the side heaters 51 and 52 is released. As a result, a finished book of paper-like S shown in FIG. 9 is completed.

<Effects of First Embodiment>
As described above, the print-receiving tape 100 according to this embodiment includes the hot melt adhesive layer 101b that can be melted at a temperature equal to or higher than a predetermined melting point to exhibit adhesiveness. Thereby, after binding the spine cover sheet L created from the print-receiving tape 100 during bookbinding so as to wrap the edges of the paper-like sheet S of a plurality of pages, the paper-like sheet S is fixed by heating it above the melting point. Can do. Then, a desired print R can be formed on the transfer layer 101c provided on the opposite side of the base material layer 101a from the hot melt adhesive layer 101b, and desired description items can be displayed.

  And in the to-be-printed tape 100, the hot-melt-adhesion layer 101b is formed so that the surface may become smooth in the base material layer 101a as mentioned above. Therefore, when the base material layer 101a provided with the hot melt adhesive layer 101b is conveyed in the roll manufacturing apparatus 110 or the printing apparatus 1, it is easier and smoother than when the surface of the hot melt adhesive layer 101b has irregularities. Can be conveyed. Further, when printing is performed on the transfer layer 101c by thermal transfer from the ink ribbon 26 in the printing apparatus 1, it is possible to form a print of good quality without blurring.

  In particular, the ink ribbon 26 fed from the ribbon supply roll IR1 of the tape cassette 70 is superposed on the print-receiving tape 100 fed from the bookbinding tape roll TR1, and is applied to the print-receiving tape 100 by thermal transfer of ink from the ink ribbon 26. A print is formed. At this time, since the surface of the hot melt adhesive layer 101b is smooth as described above, the superposition for the thermal transfer at the time of printing can be performed uniformly. This also makes it possible to improve the printing quality with certainty.

  In this embodiment, in particular, as shown in FIG. 10A and FIG. 4 described above, a transfer layer 101c is provided on the opposite side (upper side in the drawing) of the base material layer 101a from the hot melt adhesive layer 101b. It has a three-layer laminated structure. Thus, by setting it as the minimum required 3 layer laminated structure, the thickness direction dimension of the to-be-printed tape 100 can be reduced, and it can convey more easily and smoothly by this.

  In this embodiment, the melt viscosity condition at the melting point of the hot-melt adhesive layer 101b is, for example, a melt viscosity of 10,000 mPa · S or less when the melting point is 150 ° C. Further, the melting point of the ink ribbon 26 at the time of thermal transfer is set to be higher than 150 ° C. and 200 ° C. or lower (preferably 160 ° C. or higher and 200 ° C. or lower). That is, the melting point of the ink ribbon 26 is higher than the melting point of the hot-melt adhesive layer 101b (that can be melted and subjected to adhesion). As a result, when the spine cover sheet L, which is formed by being printed with the ink ribbon 26 and cut in the printing apparatus 1 and then cut, is heated to develop a hot melt adhesive paper, the ink is remelted. Occurrence of dirt and fading can be prevented.

  In the present embodiment, in particular, the dimension range in the thickness direction of the hot melt adhesive layer 101b is 200 μm or more and 400 μm or less. Thus, by fixing the thickness of the hot-melt adhesive layer 101b to 200 μm or more sufficiently, there was some irregularity at the end of each page when fixing a plurality of pages of paper sheets S as a back cover during bookbinding. However, it is possible to securely fix the plurality of pages of paper-like S (see FIGS. 6 to 9).

Adjacent to one side (the lower side in the figure) in the thickness direction, a coated material layer 101d composed of a paper material or the like as described above may be provided. Also in this case, similarly to the above, the hot-melt adhesive layer 101b has a four-layer laminated structure in which the surface of the material layer 101d is further coated on one side in the thickness direction (the lower side in the drawing) so as to have a smooth surface. .

  In addition, polyvinyl chloride (PVC) etc. can be used as a vinyl resin which comprises the base material layer 101a.

  In this modification, the print-receiving tape 100 incorporating the base material layer 101a using a vinyl resin can be realized.

Copolymer (EMMA), polybutene (PB), polybutadiene (BDR), polymethylpentene (PMP), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polyimide (PI), poly Ether imide (PEI), polyether ketone (PEK), polyether ether ketone (PEEK), nylon (NY), polyamide (PA), polycarbonate (PC), polystyrene (PS), expanded polystyrene (FS / EPS), poly Vinyl chloride (PVC), poly Vinylidene chloride (PVDC), saponified ethylene-vinyl acetate copolymer (EVOH), polyvinyl alcohol (PVA), normal cellophane (PT), moisture-proof cellophane (MST), polyacrylonitrile (PAN), vinylon (VL), polyurethane ( (PU), triacetyl cell source (TAC), metal foil such as aluminum foil (AI) / copper foil, film (VM) by vacuum deposition (for example, aluminum), non-woven fabric, glass cloth, or the like may be used. In these cases, the same effect is obtained.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the print-receiving tape 100 including the hot melt adhesive layer 101b is created by a method different from that in the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted or simplified as appropriate.

  An outline of a printing tape production method (manufacturing method) in this embodiment will be described with reference to FIGS. First, as shown in FIG. 11A, a predetermined melting point is applied to the surface (upper surface) of the release treatment surface 104a of the release material 104 (corresponding to a release material layer) having a release treatment surface 104a that can be removed. The hot melt adhesive layer 101b is formed by applying a hot melt that can be melted at the above temperature and exhibit adhesiveness (corresponding to an application procedure). However, in this case, unlike the first embodiment, the dimensional accuracy and the like of the hot melt adhesive layer 101b do not need to be high, and relatively low accuracy is sufficient. Therefore, at this stage, as shown in the drawing, the upper surface of the hot-melt adhesive layer 101b after application (the surface opposite to the release treatment surface 104) remains uneven.

  Thereafter, as shown in FIG. 11 (b), the base material layer 101a (the two layers are the material tape 100 ′) having the transfer layer 101c on the upper surface is placed on the (uneven side) of the hot melt adhesive layer 101b. The hot melt adhesive layer 101b is transferred to the base material layer 101a by pressing against the release material 104 so that the surface is in close contact with the surface (lower surface) of the base material layer 101a (corresponding to a transfer procedure). In the intermediate tape 100A obtained in this state, the release material 104, the hot melt is directed from one side in the thickness direction (lower side in FIG. 11) to the other side in the thickness direction (upper side in FIG. 11). It has a four-layer structure in which the adhesive layer 101b, the base material layer 101a, and the transfer layer 101c are laminated adjacently in this order.

  Thereafter, as shown in FIG. 11C, the release material 104 is peeled off from the base material layer 101a. As a result, as shown in FIG. 11D, the hot-melt adhesive layer 101b separated from the mold release surface 104a and transferred to the surface of the base material layer 101a remains on the base material layer 101a side. As a result, the hot melt adhesive layer 101b, the base material layer 101a, and the transfer layer 101c are directed from one side in the thickness direction (lower side in FIG. 11) to the other side in the thickness direction (upper side in FIG. 11). Thus, a print-receiving tape 100 having a three-layer structure (similar to the first embodiment) stacked adjacently in this order is obtained. At that time, the surface of the hot-melt adhesive layer 101b remaining on the base material layer 101a is separated from the release treatment surface 104a of the base material layer 101a, and thus becomes a very smooth surface.

  Details for realizing generation of the print-receiving tape 100 by the above-described method will be described with reference to FIGS. In this embodiment, two roll manufacturing apparatuses 110A and 110B at the front stage and the rear stage are used.

<Roll manufacturing equipment (previous stage)>
First, FIG. 12 shows a configuration example of a roll manufacturing apparatus 110A (corresponding to an example of a processing apparatus) that performs processing in the preceding stage.

  In the roll manufacturing apparatus 110 </ b> A shown in FIG. 12, a release material roll SR <b> 1 wound with a release material 104 (which is originally spiral but simplified and shown as a concentric circle) is rotatably supported by a support shaft 607. ing. The release material 104 fed from the release material roll SR1 is sent to the transport roller 602 via the feed roller pair 601. Then, when the release material 104 passes through the conveying roller 602, the liquid material is discharged from the discharge nozzle 603A ′ of the first fixed amount discharger 603 provided with a discharge nozzle 603A ′ (details will be described later) different from that of the first embodiment. The hot melt adhesive 606 is discharged. The discharged hot melt adhesive 606 is applied on the upper side of the release material 104, and the hot melt adhesive layer 101b is sequentially formed on the upper side of the release material 104 (corresponding to the other side in the thickness direction). As the hot melt adhesive 606 at this time, for example, the one having a melt viscosity of 10000 mPa · S or less when the melting point is 150 ° C. is used as in the first embodiment.

  FIG. 13 shows the discharge nozzle 603A ′. In the discharge nozzle 603A ′, five discharge ducts Dc are arranged along the width direction of the release material 104 in this example. Adjacent discharge ducts Dc are partitioned by a partition portion Bd. As described above, when the release material 104 passes through the conveying roller 602, the hot melt adhesive 606 discharged from each duct Dc of the discharge nozzle 603A ′ is applied on the release material 104, respectively. As a result, as shown in FIG. 13 (in this example), five rows of hot-melt adhesive layers 101b (corresponding to hot-melt application portions) are sequentially formed on the release material 104 in the form of lines. In this way, the hot-melt adhesive layers 101 b are arranged separately from each other in the width direction of the release material 104 and extend in the longitudinal direction of the release material 104. In addition, in the part of the release material 104 corresponding to the partition portion Bd (that is, between the two hot melt adhesive layers 101b and 101b adjacent in the width direction), there is a space portion SS without hot melt. .

  Returning to FIG. 12, on the other hand, above the conveying path of the release material 104, and similarly to the first embodiment, the tape base roll BR around which the material tape 100 ′ is wound is rotatable by the support shaft 600. It is supported. Similar to the first embodiment, the material tape 100 ′ includes a base material layer 101 a and a transfer layer 101 c provided adjacent to the other side of the base material layer 101 a in the thickness direction. Then, the hot melt adhesive layer (by a bonding mechanism such as a bonding roller not shown) is applied to the release material layer 104 conveyed as described above from the material tape 100 ′ fed out from the tape base roll BR. Bonding is performed so as to sandwich 101b. Thus, an intermediate tape 100A including the release material 104, the hot-melt adhesive layer 101b, the base material layer 101a, and the transfer layer 101c is formed from one side to the other side in the thickness direction. It should be noted that since the hot-melt adhesive layer 101b is not present in the above-described four-layer structure in the region where the space SS is present, the release material 104 and the base material layer 101a are interposed through the space without the hot melt. Are stacked in the thickness direction.

  The intermediate tape 100A (corresponding to an example of a bookbinding sheet in the present embodiment) formed so as to enclose the hot melt adhesive layer 101b as described above is conveyed in a substantially horizontal direction, and an unnecessary portion removing device 609 is used. Then, unnecessary portions at both ends in the width direction are cut and removed, and then wound around the outer periphery of an appropriate winding member (not shown) having the winding shaft 612 as an axis, and the intermediate tape roll MR. (Corresponding to the bookbinding sheet roll in the present embodiment) is generated.

<Roll manufacturing equipment (second stage)>
Next, FIG. 14 shows a configuration example of a roll manufacturing apparatus 110B (corresponding to an example of a processing apparatus) that performs processing at a later stage using the intermediate tape roll MR. In this roll manufacturing apparatus 110B, the intermediate tape roll MR (originally spiral but simplified and shown in a concentric circle) wound with the intermediate tape 100A is rotatably supported by a support shaft 613. Has been. As described above, the intermediate tape 100A includes the release material 104, the hot-melt adhesive layer 101b, and the base material layer 101a from the one side in the thickness direction (the lower side in the drawing) toward the other side (the upper side in the drawing). , And the transfer layer 101c. The intermediate tape 100 </ b> A fed out from the intermediate tape roll MR is sent to the first roller 505.

  In the first roller 505, among the four-layer structure included in the intermediate tape 100A, the release material 104 is peeled from the other three layers (the hot-melt adhesive layer 101b, the base material layer 101a, and the transfer layer 101c). It is. The peeled release material 104 is wound around a release paper roll SR2 that is rotatably supported by a winding shaft 615 via a second roller 506.

  On the other hand, the other three layers (hereinafter, appropriately referred to as “three-layer laminated tape 100 </ b> B”) after the release material 104 is peeled off are introduced into the slitter device 609. In this example, the slitter device 609 includes four cutting blades (not shown). The three-layer laminated tape 100B passes through the slitter device 609, and is cut by the four cutting blades at a cutting line CL indicated by a broken line in FIG. That is, the three-layer laminated tape 100B is cut in the longitudinal direction of the tape between two adjacent hot melt adhesive layers 101b and 101b among the hot melt adhesive layers 101b formed in five rows as described above. As a result, as shown in FIG. 15B, the hot melt adhesive layer 101b has ear portions M and M (corresponding to exposed portions) where the base layer 101a is exposed without the hot melt application portion on both sides in the width direction. Five narrow and narrow print-receiving tapes 100 (corresponding to the newly obtained bookbinding sheet of this embodiment) are obtained. Each of these five print-receiving tapes 100 is wound as a printing tape roll TR2 that is rotatably supported by a winding shaft 614.

  The printing tape roll TR2 generated as described above is used in the printing apparatus 1 like the printing tape roll TR1 of the first embodiment, and is applied to the print-receiving tape 100 fed out from the printing tape roll TR2. The print is formed and cut to produce the spine cover sheet L. Further, using the spine cover sheet L, bookbinding is executed by the bookbinding apparatus 120 similar to that of the first embodiment.

  As described above, in this embodiment, the intermediate tape 100 </ b> A is generated by pressing the hot melt adhesive layer 101 b applied in an uneven manner as described above against the release material 104. That is, in this intermediate tape 100A, one side (lower side in FIG. 11) in the thickness direction of the hot-melt adhesive layer 101b on the surface of the other side (upper side in FIG. 11) of the release material 104 in the thickness direction. The mold release processing surface 104a adhering to the surface is detachable. The surface of the hot-melt adhesive layer 101b of the print-receiving tape 100 obtained by peeling off the release material 104 from the intermediate tape 100A is separated from the release treatment surface 104a of the base material layer 101a, so that it is extremely smooth. It becomes a serious aspect.

  As a result, unlike the structure in which hot melt is simply applied to the base material layer 101a with low accuracy (hereinafter referred to as simple application structure), in the present embodiment, the hot melt adhesive layer 101b having a smooth surface is It can be easily formed on the base material layer 101a. Therefore, as in the first embodiment, a tape (intermediate tape 100A, three-layer laminated tape 100B, or print-receiving tape 100) including the hot-melt adhesive layer 101b or the base material layer 101a is used as the roll manufacturing apparatuses 110A, 110B, When transporting in the printing apparatus 1, it can be transported easily and smoothly as compared with the simple coating structure in which the hot melt adhesive layer 101b has irregularities on the surface thereof. In addition, when printing is performed on the transfer layer 101c of the print-receiving tape 100 in the printing apparatus 1 (that is, on the side opposite to the hot-melt adhesive layer 101b of the base material layer 101a), printing with good quality without blurring due to unevenness. Can be formed.

  In this embodiment, in particular, the tape 100 to be printed has ear portions M and M (corresponding to exposed portions) where the base material layer 101a is exposed on both sides in the width direction of the hot melt adhesive layer 101b (no hot melt is applied). Have. Accordingly, when the spine cover sheet L generated using the print-receiving tape 100 is folded in the width direction into a U-shaped cross section to form the spine cover during bookbinding (see FIGS. 6 to 9 described above), The U-shaped both end portions become the non-coating portion of the hot melt. As a result, it is possible to reliably prevent the hot melt remaining from the both end portions from protruding during the bookbinding. In addition, you may apply at the time of preparation of the to-be-printed tape 100 in the said 1st Embodiment that the structure which provides the non-application part (exposed site | part which the base material layer exposed) of a hot melt in such both ends. In this case as well, the effect of preventing the hot melt from protruding can be obtained.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
