DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film sticking apparatus which cuts a long strip-shaped base film to form a film of a predetermined length and sticks the film to a stick such as a can.
In particular, the present invention relates to a film sticking apparatus capable of sticking a thin film to a body to be stuck without generating wrinkles.

2. Description of the Related Art As a film sticking apparatus, there is a labeling apparatus for sticking a label made of a synthetic resin film on a body of a body to be bonded such as an aluminum can as shown in FIG. The labeling device 70 includes a cutting and conveying unit 71 that forms a label L by cutting a long band-shaped label forming substrate M made of a synthetic resin film into a predetermined length and conveys the label L to a delivery position α. 71, the label L conveyed to the delivery position α is received at the delivery position α, conveyed to the label winding position β, and attached to the outer peripheral surface of the body of the adherend C supplied to the winding position β. And a drum 74.

The cutting / conveying means 71 includes a rotary cutter 72 having a cutting blade 72a attached to the outer peripheral surface thereof for holding the fed label forming substrate M, and a cutting / conveying roll 73.
The label transfer base material M to be fed can be suction-held on the outer peripheral surface thereof by suction means (not shown) mounted on the cutting / conveying roll 73. Therefore, the rotary cutter 72 and the cutting / conveying roll 73 rotate (rotate) while the label forming substrate M is held therebetween.
Then, the label forming base material M is cut to a predetermined length by the cooperative action of the rotary cutter 72 and the cutting / conveying roll 73 while being conveyed to the delivery position α while being held by suction on the outer peripheral surface of the cutting / conveying roll 73. Is formed. Then, the label L thus formed is
It is delivered to the attaching drum 74 at the delivery position α.

The sticking drum 74 rotates at a larger peripheral speed than the cutting / conveying roll 73, and the label L can be suction-held on the outer peripheral surface thereof by suction means (not shown) mounted thereon. I can do it. Therefore, the labels L successively delivered at the delivery position α are sucked and held at regular intervals on the outer peripheral surface of the attaching drum 74 in order to set the attaching timing to the adherend C, and are sequentially conveyed to the attaching position β.

The sticking position β is supplied by a supply means (not shown) while the to-be-adhered body C is rotated while being rotated. Is pressed along the outer peripheral surface of the attaching drum 74 while being pressed against the label L sucked and held on the outer peripheral surface of the object C.
Is moved, the label L sucked and held on the outer peripheral surface of the attaching drum 74 is attached while being wound on the outer peripheral surface of the trunk portion of the adherend C. In the case where the label L is a heat-sensitive adhesive label, the adherend C is heated to the activation temperature of the heat-sensitive adhesive applied to the label L in advance.

[0006]

By the way, when the length of the label L to be affixed is longer than the distance between the cutting position of the label forming substrate M and the delivery position α of the label L, The label forming base material M is cut after the leading end portion of the label forming base material M is delivered to the sticking drum 74. However, as described above, the peripheral speed of the sticking drum 74 is lower than that of the cutting and conveying roll 73. Since it is large, the label forming base
After the leading end of the label forming base material M is sucked and held on the outer peripheral surface of the sticking drum 74 and until the label forming base material M is cut, the label forming base material M is pulled by the sticking drum 74 to be in tension. . When the label-forming base material M is formed of a synthetic resin film having a somewhat large thickness, it is not so much a problem, but the thickness is 20 μm.
In the case of the label-forming substrate M formed of a thin synthetic resin film having a small thickness, a tension wrinkle that undulates in the width direction of the label-forming substrate M due to the tension force, and finally the label L Cannot be stuck neatly to the body C to be stuck.

In particular, since the outer peripheral surface of the attaching drum 74 is generally covered with an elastic member such as rubber in order to press the outer peripheral surface of the torso of the adherend C, the label formed by suction and holding is formed. The frictional resistance between the substrate M and the outer peripheral surface of the drum is large, so that the label-forming substrate M tends to be more easily tensioned than a normal drum.

Further, as described above, when the label L is attached to the adhered body C, the adhered body C is pressed against the outer peripheral surface of the attaching drum 74, so that the label L is formed on the outer peripheral surface of the attaching drum 74. In the case where the suction hole portion is not pressurized and the label L to be stuck is thin, a trace of the suction hole portion which is not pressurized remains on the label L side. Therefore, when attaching the thin label L, a large suction hole cannot be formed on the outer peripheral surface of the attaching drum 74, and the attaching drum 7
Since the suction force of the sticking drum 74 cannot be sufficiently secured, if the slipperiness of the outer peripheral surface of the sticking drum 74 is improved in order to prevent the occurrence of tension wrinkles as described above,
A new problem arises in that the positioning accuracy of the label L on the outer peripheral surface of the No. 4 becomes poor.

In order to solve such a problem, the diameter of the cutting / conveying roll 73 is increased so that the leading end of the label forming base material M reaches the delivery position α, that is, the label forming base material M It is conceivable to cut the label-forming base material M before the leading end is sucked and held by the affixing drum 74. However, since the cutting / conveying roll 73 is used for cutting, the cutting / conveying roll 73 is compared with a mere conveying drum. And expensive parts,
Increasing the diameter of the cutting / conveying roll 73 leads to a problem that the cost is considerably increased.

In view of the above-mentioned various problems, an object of the present invention is to provide a film sticking apparatus capable of sticking a thin and rigid film to a body to be stuck without causing wrinkles. To provide.

[0011]

Means for Solving the Problems and Effects Therefor To solve the above problems, the present invention forms a film of a predetermined length by cutting a long strip-shaped base film, and rotates the film by itself. A film sticking apparatus that is attached to a body to be rotated while being suction-held on an outer circumferential surface of the sticking drum, and is attached to the body while being wound around the body to be stuck. A cutting and conveying roll that cuts to a predetermined length to form the film by cooperating with a cutting blade while being conveyed to the first delivery position by being rotated while being sucked and held at the first delivery position; The film is conveyed to the second delivery position by rotating while holding the film on the outer peripheral surface, and the film is delivered to the sticking drum at the second delivery position. Slipperiness of the outer circumferential surface is intended to provide with that film sticking apparatus and a good delivery drum.

[0012] In the film sticking apparatus configured as described above, the film is transferred from the cutting / conveying roll to the sticking drum via the transfer drum having a good slippery outer peripheral surface. The distance between the cutting position of the material film and the first delivery position is larger than the distance between the cutting position and the first delivery position. The leading end of the film can easily slide on the outer peripheral surface of the delivery drum. Therefore, the base film is not subjected to excessive tension and the formed film does not have tension wrinkles, so that the film can be finally stuck neatly to the adherend.

Further, since the peripheral speeds of the delivery drum and the attaching drum can be set to be substantially the same, compared with the conventional labeling device for transferring the film between the cutting and conveying roll and the attaching drum having different peripheral speeds. In addition, there is an effect that the film can be smoothly transferred to the outer peripheral surface of the attaching drum where it is difficult to secure a sufficient suction force, and the positioning accuracy of the film on the outer peripheral surface of the attaching drum can be sufficiently ensured.

Further, by separately providing a low-priced delivery drum, it is not necessary to increase the diameter of the expensive cutting and conveying roll, which is advantageous in terms of cost.

In particular, as in the film sticking device according to claim 2, the delivery drum releases suction near the second delivery position, and transfers the film from the outer peripheral surface of the delivery drum from which suction has been released to the film. Conversely, by blowing air, the leading end of the film sucked and held on the outer peripheral surface of the delivery drum is forcibly pressed against the outer peripheral surface of the sticking drum, and the film to be delivered is transferred to the transfer drum. While being separated from the outer peripheral surface of the delivery drum, the outer peripheral surface of the sticking drum is sucked and held on the outer peripheral surface, and air is blown toward the front side of the film in the moving direction of the film at the leading end of the film. When the air blowing angle of the delivery drum is adjusted, slack occurs when the film is transferred from the delivery drum to the application drum. State film is hardly sucked and held on the outer circumferential surface of the patch drum has an effect that a more beautiful film can be stuck to a landing member.

[0016]

Embodiments will be described below with reference to the drawings. A labeling device 1 which is an embodiment of the film sticking device shown in FIG. 1 cuts a long band-shaped label forming substrate M to which a heat-sensitive adhesive label (hereinafter, referred to as a label) of a predetermined length is continuously connected. While forming a label of a predetermined length by sequentially cutting at P1,
The label is sequentially attached so as to be wound around the outer peripheral surface of a body of an aluminum can (hereinafter, referred to as an aluminum can) C as an object to be attached, which is transported to a predetermined label attaching position P4. Yes, the label has a thickness of 12
The printing is performed on the inner surface of a polyethylene terephthalate film having a thickness of about μm and having no rigidity, and a heat-sensitive adhesive is applied.

As shown in FIGS. 1, 2 and 5, this labeling apparatus 1 comprises a pair of feeders for continuously feeding a long label-forming base material M wound in a roll to a cutting position P1. A cutting in which a label L is formed by successively cutting a supply roller 10 and a label forming substrate M supplied by the supply roller 10 at a predetermined cut pitch at a cutting position P1 while transporting the label forming substrate M to a first delivery position P2. Conveying means 2
0, a label affixing means 40 for affixing the label L to the outer peripheral surface of the body of the aluminum can C at the label affixing position P4, and the label L cut by the cutting and conveying means 20 from the label forming substrate M at the first delivery position. The delivery drum 30, which receives the sheet at P2 and transfers it to the label attaching means 40 at the second delivery position P3, the can supply means 50 for supplying the aluminum can C to the label attaching means 40, and the label L attached by the label attaching means 40. And a can discharging means 60 for discharging the obtained aluminum can C.

As shown in FIG. 2, the cutting / conveying means 20 sucks a rotary cutter 21 having a cutting blade 21a attached to the outer peripheral surface thereof, and a label forming substrate M supplied by the feed roller 10 onto the outer peripheral surface. It holds and transports to the first delivery position P2, and also includes a cutting and transporting roll 22 that sequentially cuts the label-forming base material M into a predetermined length by cooperation with the rotary cutter 21.

As shown in FIG. 1, the cutting / conveying roll 22 includes a roll main body 23 which is rotationally driven by a driving means (not shown), and a fixing portion with which the roll main body 23 is slidably contacted. In the outer peripheral surface of the roll body 23, a plurality of through holes 23 are provided at regular intervals in the circumferential direction.
a is formed, and the roll body 2 is
3, a suction groove 24a connected to suction means (not shown), which communicates with the through hole 23a from the cutting position P1 to just before the first delivery position P2, and the first delivery position P2. An ejection groove 24b connected to ejection means (not shown), which communicates with the through hole 23a, is formed.

Therefore, the label forming substrate M supplied to the cutting position P1 is suction-held by the suction groove 24a on the outer peripheral surface of the roll body 23 which rotates (rotates), and is held in the first delivery position P2. Transported to When the label forming base material M reaches the first delivery position P2, the through hole 23a is communicated with the discharge groove 24b after the communication with the suction groove 24a is cut off.
By the discharge action of 4b, air is discharged from the outer peripheral surface of the roll main body 23, and the label forming substrate M sucked and held on the outer peripheral surface of the roll main body 23 separates from the roll main body 23 and the outer periphery of a delivery drum 30 described later. The transfer drum 30 is forcibly pressed against the transfer surface and is suction-held on the outer peripheral surface of the delivery drum 30.

After the leading end of the label-forming base material M is delivered to the delivery drum 30 in this manner, the label-forming base material M is cut by the rotary cutter 21 and the cutting / conveying roll 22 to form the label L. Then, the formed label L is delivered to the delivery drum 30.

As shown in FIG. 2, the delivery drum 30 has an outer peripheral surface which is close to the outer peripheral surface of the cutting / conveying roll 22 at a first delivery position P2 and a labeling drum of the label attaching means 40 at a second delivery position P3. The cutting / conveying roll 22 is installed so as to be close to the outer peripheral surface of the cutting / conveying roll 22 and rotates (rotates) in a direction opposite to that of the cutting / conveying roll 22 at a higher peripheral speed.

The delivery drum 30 is composed of a drum main body 31 which is driven to rotate by driving means (not shown), and a fixing portion 33 with which the drum main body 31 is slidably contacted. The surface is coated with Teflon or the like to ensure good slipperiness.

After the leading end portion of the label-forming base material M is delivered to the delivery drum 30 at the first delivery position P2 and before the label-forming base material M is cut, the peripheral speed is higher than that of the cutting / conveying roll 22. Although the label forming substrate M is pulled by the delivery drum 30, the delivery drum 30 is suction-held on the outer circumference of the delivery drum 30 because the outer circumference of the delivery drum 30 has good slipperiness as described above. The label forming substrate M can easily slide on the outer peripheral surface.
Therefore, no excessive tension is applied to the label-forming base material M before the label-forming base material M is delivered to the delivery drum 30 and cut off.
No tension wrinkles occur.

The drum main body 31 is formed with a large number of through holes 32 opened to the outer peripheral surface thereof so as to be aligned at regular intervals in the circumferential direction and the width direction of the outer peripheral surface. Are open to the contact surface with the fixing portion 33 in a state where the plurality of through-holes 32 are connected to each other.

As shown in FIG. 3, the through hole 32 is provided in the label forming base material M delivered at the first delivery position P2.
(Label L) is composed of a suction / ejection hole 32a formed so as to correspond to a position in contact with the leading end of the label (L), and a suction hole 32b formed at other positions. The suction hole 32b is formed so as to be inclined at 30 degrees forward in the moving direction of the drum body 31 (forward in the moving direction of the label L) with respect to the radial direction of the drum body 31. It is formed along.

In the fixing portion 33, a suction groove communicating with the suction / discharge hole 32a and the suction hole 32b from the first delivery position P2 to just before the second delivery position P3 is formed on the contact surface with the drum body 31. 33a and a discharge groove 33b communicating only with the suction and discharge hole 32a at the second delivery position P3 are formed, and the suction groove 33a and the discharge groove 33b are connected to suction means and discharge means (not shown), respectively.

Therefore, the label L delivered from the cutting and conveying means 20 at the first delivery position P2 is
Is transported to the second delivery position P3 while being suction-held on the outer peripheral surface of the drum body 31 by the suction action of
At the delivery position P3, the suction is temporarily released, and as described above, the suction discharge hole 32a communicates with the discharge groove 33b, so that air is discharged from the outer peripheral surface of the drum main body 31 through the suction discharge hole 32a. Thereby, the drum body 31
The leading end of the label L sucked and held on the outer peripheral surface is separated from the outer peripheral surface and is forcibly pressed against the outer peripheral surface of the sticking drum.

As described above, the suction / discharge hole 32a is formed in a state of being inclined by 30 degrees forward in the moving direction of the drum body 31, so that the air discharged at the second delivery position P3 is as shown in FIG. As shown, the label L is discharged toward the front in the moving direction. Therefore, as shown in the figure, it is difficult for the air blown to the label L to move backward in the moving direction of the label L, and even if the label L to be delivered is a thin and rigid label, the delivery of the label L At this time, the delivery of the label L is performed so that the leading end of the label L does not become loose and passes on a straight line connecting the outer peripheral surface of the delivery drum 30 and the outer peripheral surface of the sticking drum 41. As a result, the label L is reliably delivered to the predetermined position of the sticking drum 41, and the leading end of the delivered label L is not sucked and held in a partially raised state.

The label affixing means 40 is shown in FIGS.
As shown in the figure, a sticking drum 41 that sucks and holds the label L delivered at the second delivery position P3 on the outer peripheral surface and transports the label L to the sticking position P4, and preliminarily transfers the label L during the transportation by the sticking drum 41. A radiant heat heater (near infrared heater) 42 for heating and a number of mandrels 43 for transporting the aluminum can C supplied by the can supply means 50 at the can supply position P5 to the can discharge position P6 so as to pass through the sticking position P4. And a radiant heat heater (far-infrared heater) 44 fixedly installed on each mandrel 43, respectively.
And a radiant heat heater (far-infrared heater) 45 for supplementarily heating the aluminum can C inserted into the mandrel 43 between the can supply position P5 and the sticking position P4, and a sticking position P4.
And a guide member 46 for repressurizing the label L affixed to the aluminum can C.

The sticking drum 41 has a drum body 41a (see FIG. 2) which is driven to rotate by driving means (not shown), similarly to the delivery drum 30 described above, and a fixing portion with which the drum body 41a slidably contacts. (Not shown), and the outer peripheral surface of the drum main body 41a is covered with an elastic member such as rubber.

Similarly to the delivery drum 30, the drum main body 41a is formed such that a large number of suction holes 41b opened on the outer peripheral surface thereof are arranged at regular intervals in the circumferential direction and the width direction of the outer peripheral surface. (See FIG. 2), and a plurality of suction holes 41b constituting each row of holes in the width direction are open to the contact surface with the fixing portion in a state of communicating with each other.

In the fixing portion, a suction groove (not shown) communicating with the suction hole 41b is formed on the contact surface with the drum main body 41a from the second delivery position P3 to the sticking position P4. This suction groove is connected to suction means (not shown). Therefore, the label L delivered from the delivery drum 30 at the second delivery position P3 is conveyed to the sticking position P4 while being held by suction on the outer peripheral surface of the drum main body 41a.

The mandrel 43 is moved by a rotational driving force of a driving means (not shown) to a can supply position P5 and a sticking position P5.
The aluminum can C inserted at the can supply position P5 is transported to the sticking position P4, and rotated at the sticking position P4. The aluminum can C is moved by a predetermined distance along the outer peripheral surface of the attaching drum 41 while being pressed against the label L sucked and held on the outer peripheral surface of the attaching drum 41, so that the outer peripheral surface of the body of the aluminum can C is pressed. After the label L is attached to the aluminum can, the aluminum can C is transported to the can discharge position P6.

The radiant heat heater 44 includes a mandrel 43
Are arranged inside the rotating orbit of the can, and together with the mandrel 43, the can supply position P5, the sticking position P4, and the can discharge position P6.
It moves in a circular orbit that passes through. Therefore, the mandrel 43 itself is heated by the radiant heat heater 44 between the can discharge position P6 where the aluminum can C is not inserted into the mandrel 43 and the can supply position P5, and is inserted into the mandrel 43 at the can supply position P5. The heated aluminum can C is heated by coming into contact with the heated mandrel 43. And the aluminum can C is a mandrel 43
While being transported from the can supply position P5 to the sticking position P4 while being inserted into the radiant heat heater 44 and the mandrel 4
The aluminum can C is directly heated by the radiant heat heater 45 disposed outside the rotation track of the aluminum can 3, and when the aluminum can C reaches the sticking position P4, the aluminum can C is labeled with the label L.
The temperature is reliably raised to a predetermined temperature equal to or higher than the activation temperature of the heat-sensitive adhesive. In addition, from the sticking position P4 where the label L is stuck to the aluminum can C inserted into the mandrel 43 to the can discharging position P6, the radiant heat heater 44 is provided.
Thus, the label L attached to the aluminum can C is heated.

The can supply position P5 to the can discharge position P6
Until the mandrel 43 itself rotates,
The aluminum can C and the label L attached to the aluminum can C are not partially heated by the radiant heat heater 44, and the aluminum can C and the label L are always uniformly heated.

The guide member 46 includes a pressing plate 46a formed by an elastic member such as rubber disposed outside the mandrel 43 along the rotation path between the sticking position P4 and the can discharging position P6. And an aluminum can C to which the label L is attached at the attaching position P4.
Before reaching the can discharge position P6, the label L is repressurized by moving while rotating while being pressed against the heated pressure plate 46a. As described above, the radiant heat heater 44 that moves together with the mandrel 43 is between the sticking position P4 and the can discharge position P6.
As a result, the label L is continuously heated.

As described above, if the label L attached to the aluminum can C at the attaching position P4 is re-pressed by the guide member 46, the label L is completely attached to the aluminum can C at the attaching position P4. Even when the label L is not adhered, the label L can be firmly adhered to the aluminum can C by re-pressing thereafter. Further, by re-pressing the label L by the guide member 46 after the label L is attached, it is possible to effectively prevent the occurrence of a wavy state on the surface due to the softening of the thin and rigid label L, and to prevent the aluminum can from being pressed. It becomes possible to lower the temperature of the mandrel 43 itself for heating C.

As shown in FIG. 1, the can supply means 50 supplies a supply chute 51 for continuously sending out a large number of aluminum cans C, and supplies the aluminum can C sent by the supply chute 51 at a predetermined timing. The aluminum can C supplied to the can supply position P5 by the can supply means 50 is fitted into the mandrel 43 by a fitting mechanism (not shown).

As shown in FIG. 1, the can discharging means 60 includes a star wheel 61 for receiving the aluminum can C having the label L attached thereto at the attaching position P4 at a predetermined timing at the can discharging position P6, And a discharge chute 62 for discharging the aluminum can C received by the wheel 61. The aluminum can C transported to the can discharge position P6 by the mandrel 43 is extracted from the mandrel 43 by an unillustrated extraction mechanism. Is discharged by the can discharging means 60.

The labeling apparatus 1 configured as described above
In the above, as described above, the delivery drum 30 having good slippery on the outer peripheral surface for delivering the label L is provided between the cutting / conveying means 20 and the attaching drum 41, and the label is transferred to the delivery drum 30. Since the transfer of the label L is performed while the leading end of the base material M is slid on the outer peripheral surface of the drum, excessive tension is not applied to the label forming base material M.
Even when the label-forming base material M is formed of a thin, rigid film, the cut label L does not generate tension wrinkles, and finally the aluminum can C
The label L can be stuck to the body of the camera.

Further, by providing the delivery drum 30, the delivery of the label L from the delivery drum 30 to the attaching drum 41 can be performed at substantially the same peripheral speed, which is sufficient for a thin and rigid label L. Delivery of the label L to the outer peripheral surface of the attaching drum 41, which is difficult to secure a sufficient suction force, can be performed smoothly, and sufficient positioning accuracy of the label L on the outer peripheral surface of the attaching drum 41 can be ensured. further,
By separately providing the inexpensive delivery drum 30, there is no need to increase the diameter of the expensive cutting / conveying roll 22, which is advantageous in terms of cost.

Further, the transfer drum 30 and the sticking drum 41
When transferring the label L to the leading end of the label L sucked and held on the outer peripheral surface of the delivery drum 30, the label L
Is blown toward the front side in the moving direction of the label L (the front side in the moving direction of the delivery drum 30), so that it is difficult for the blown air to flow to the rear side in the moving direction of the label L. In addition, it is possible to effectively prevent the label L from being displaced or being partially lifted after being delivered due to the slack of the leading end of the thin and rigid label L.
It is possible to paste it neatly.

In this embodiment, the outer peripheral surface of the delivery drum 30 is coated with Teflon in order to improve the slipperiness. However, the present invention is not limited to such a method. Alternatively, it is also possible to improve the slipperiness by performing fine embossing (roughening) on the drum surface. As described above, the outer peripheral surface of the delivery drum 30 needs to have a slipperiness such that tension wrinkles do not occur when the label forming substrate M is transferred, and the label forming substrate (film) M to be suction-held is held. Is 0.01 to 0.01, for example.
It is preferable to set the value so as to be within the range of 0.5, and particularly preferable to set the value to be within the range of 0.01 to 0.3.

In this embodiment, the suction and discharge holes 32
Although the formation angle (air discharge angle) of a is set to 30 degrees with respect to the radial direction of the delivery drum 30, the formation angle (air discharge angle) is 20 to 60 degrees, and more preferably 3 degrees.
What is necessary is just to set suitably within the range of 0-45 degree | times. If the forming angle is smaller than 20 degrees, the sag preventing effect is not exhibited, and if the forming angle is larger than 60 degrees, the label L cannot be smoothly delivered to the attaching drum 41.

In this embodiment, air is blown only to the leading end of the label L.
It is also possible to blow air over the entire length from the front end to the rear end of the label L. However, in this case, not only the through hole 32 corresponding to the leading end portion of the label L but also all the through holes 32 may be inclined forward with respect to the radial direction of the delivery drum 30 in the moving direction of the label L. desirable.

In this embodiment, the case is described in which the label L formed of a thin and rigid film is affixed. However, the label L used has a normal thickness (about 30 to 60 μm). Well,
The material may be any of various materials such as a polypropylene film in addition to the polyethylene terephthalate film.

In this embodiment, the labeling device which is one mode of the film sticking device has been described.
The film sticking apparatus of the present invention is not limited to such a labeling apparatus, and it goes without saying that a simple film other than a label may be stuck to a body to be stuck.

In this embodiment, the case where the label L is stuck to the aluminum can C has been described, but the object to be stuck may be various metal cans such as a steel can.
INDUSTRIAL APPLICABILITY The film sticking apparatus of the present invention can be applied to sticking a film to various articles other than containers such as bottles and bottles other than metal cans. However, when the adherend cannot be inserted into the mandrel or cannot be directly heated, it is needless to say that the transport mechanism and the heating mechanism of the adherend need to be changed.

The tip of the film sucked and held on the outer peripheral surface of the attaching drum is forcibly pressed against the outer peripheral surface of the attaching drum so that the film to be delivered is separated from the outer peripheral surface of the delivery drum. The blowing angle of the air at the delivery drum is adjusted so that the outer peripheral surface is sucked and held, and air is blown toward the front side in the moving direction of the film at the leading end of the film.
