Description

The manufacturing method of a glass resin laminated body, and a glass resin laminated body

The present invention relates to a method for manufacturing a glass resin laminate formed by laminating and integrating a glass sheet and a resin layer with an adhesive layer, and to a glass resin laminate.

As is already known, while glass is excellent in weather resistance, chemical resistance, and scratch resistance, it has a drawback that it is easy to break with respect to physical shock or thermal shock. In order to eliminate this fault, for example, the glass resin laminated body which stuck the resin plate (resin layer) together on one side or both surfaces of a glass sheet is proposed. Resin has poor weather resistance, chemical resistance, and scratch resistance compared to glass, but has a smaller specific gravity than glass and is strong against physical impact. Therefore, in a glass resin laminated body, while it becomes possible to supplement the disadvantage in each of a glass sheet and a resin layer by each merit, compared with the glass plate which has the same plate|board thickness, significant weight reduction can be aimed at.

A glass resin laminated body is normally formed in predetermined size by cut|disconnecting a mother glass resin laminated body according to a use. As an example, Patent Document 1 discloses a glass sheet (thin glass) having a thickness of 100 µm or less, and a mother glass resin laminate having a resin layer disposed on one side or both sides of the glass sheet, including cutting a flexible film. A manufacturing method is disclosed. This manufacturing method is equipped with the process of forming a groove|channel from the outer surface side of a resin layer, and the process of cutting a mother glass resin laminated body along this groove|channel. The grooves are not formed in the glass sheet, but are formed only in the resin layer by a cutting tool or laser light.

Moreover, the method of cut|disconnecting a mother glass resin laminated body is indicated by patent document 2 using photolithography. In this method, through a number of steps such as application of a resist film, pre-baking, exposure, development and rinsing, post-baking, etching, and removal of the resist film, an etching removal portion is applied to a predetermined portion of the glass sheet (glass plate) in the mother glass resin laminate. A glass resin laminate having a predetermined dimension is formed by cutting the resin layer (resin plate) exposed by the etching removal unit.

Hereinafter, the method of manufacturing the glass resin laminated body 1 of the said structure is demonstrated. A base glass sheet 2 and a resin sheet (resin layer 3) having substantially the same size as the glass sheet 2 are laminated via an adhesive layer 4 . Thereby, the rectangular-shaped mother glass resin laminated body 5 (refer FIG. 2) is formed (mother glass resin laminated body formation process). The mother glass resin laminate 5 is not limited to a rectangular shape, and may be configured in a square shape or other shapes. In addition, for the glass sheet, the resin layer, and the adhesive layer which are the components of the mother glass resin laminated body 5, the same reference as the glass sheet 2, the resin layer 3, and the adhesive layer 4 of the glass resin laminated body 1 It is explained with a symbol.

Next, the mother glass resin laminate 5 is cut|disconnected with the cutting device 6, and the some glass resin laminated body 1 is formed (cutting process). As shown in FIG.2 and FIG.3, the cutting device 6 supports the stand (loading stand) 7 on which the mother glass resin laminated body 5 is mounted, and a part of the mother glass resin laminated body 5 A plurality of (two in the example of the drawing) pressing members 9a and 9b configured to sandwich a part of the mother glass resin laminate 5 together with the support 8 and the mounting table 7, and the mother glass resin A crack imparting member 11 for forming an initial crack 10 in the glass sheet 2 of the laminate 5 is provided. In addition, a virtual cut line 12 is set in the mother glass resin laminate 5 .

The mounting table 7 has a surface (loading surface) 7a on which the mother glass resin laminate 5 is mounted, and a slit 7b through which the support 8 is vertically passed.

In this embodiment, the support body 8 is comprised in the pointed shape. That is, the support body 8 is comprised as a knife (cutting tool) which can cut|disconnect the resin layer 3 . The support body 8 is comprised as a member of the shape whose length is longer than the width|variety (length) of the part cut|disconnected in the mother glass resin laminated body 5. As shown in FIG. In addition, while the support body 8 is comprised so that it can move in the up-down direction by the lifting device (not shown), it is comprised so that it can move in the horizontal direction by the moving mechanism (not shown).

The pressing members 9a and 9b are constituted by a cylindrical or cylindrical elastic body. The pressing members 9a and 9b may be configured to be movable in the vertical direction and configured to be rotatable around their axis. The pressing members 9a and 9b are a first pressing member 9a arranged on one end side of the mother glass resin laminate 5 and a second pressing member arranged on the other end side of the mother glass resin laminate 5 . (9b).

The crack imparting member 11 has a pointed shape. The crack imparting member 11 is disposed above the mounting table 7 and is configured to be movable in the vertical direction and the horizontal direction.

In order to cut|disconnect the mother glass resin laminated body 5 with the cutting device 6, as shown in FIG. 3, in the state which arrange|positioned the support body 8 and the crack provision member 11 at predetermined standby positions, loading The mother glass resin laminate 5 is mounted on the stand 7 . At this time, it sets so that the resin layer 3 of the mother glass resin laminated body 5 may face downward, and this resin layer 3 is made to contact the mounting surface 7a of the mounting table 7 . Then, a part of the mother glass resin laminated body 5 is pressed by each pressing member 9a, 9b.

Next, as shown in FIG. 4, the support body 8 in a stand-by position is raised, and it is made to contact the mother glass resin laminated body 5 so that it may correspond to the cut line 12. In this case, as for the support body 8, the front-end|tip part passes through the slit 7b of the mounting table 7, and protrudes upward from the mounting surface 7a of the mounting table 7. As shown in FIG. A part (central part) of the mother glass resin laminated body 5 is lifted up by the support body 8, and is spaced apart from the mounting table 7. Thereby, the mother glass resin laminated body 5 curves so that a part may become convex upward. In this case, you may narrow the separation distance (slit width of the slit 7b) of the mounting table 7 according to the curvature degree of the mother glass resin laminated body 5. That is, bending stress is provided to the glass sheet 2 of the mother glass resin laminated body 5 (a bending stress provision process). Moreover, tensile stress acts symmetrically with respect to the cut line 12 on the mother glass resin laminated body 5 by the support body 8 and the pressing members 9a, 9b. In addition, in this process, the support body 8 which is a knife only supports the resin layer 3 of the mother glass resin laminated body 5, and the resin layer 3 is not cut|disconnected. The support body 8 rises at low speed so that the resin layer 3 may not be cut|disconnected, and the mother glass resin laminated body 5 is curved.

Next, as shown in FIG. 5 , the crack imparting member 11 in the standby position is lowered and brought into contact with the glass sheet 2 of the mother glass resin laminate 5 . The crack imparting member 11 is arrange|positioned so that its front-end|tip part (lower end part) may coincide with the cutting schedule line 12 in planar view. The crack imparting member 11 comes into contact with the curved glass sheet 2 while descending from the standby position. Thereby, as shown in FIG. 5, the initial stage crack 10 is formed in the glass sheet 2 (providing process of the initial stage crack 10). Since bending stress is applied to the glass sheet 2 , the initial crack 10 advances along the cut line 12 . Thereby, the glass sheet 2 is cut along the cut line 12 (the cutting process of the glass sheet 2, refer FIG. 6). In the portion where the glass sheet 2 is cut, a slight gap 13 is formed between the cut sections.

Next, the resin layer 3 and the contact bonding layer 4 are cut|disconnected with the support body 8 (cutting process of the resin layer 3 and the contact bonding layer 4). In this case, as shown by the two-dot chain line in FIG. 7, the support body 8 is moved along the longitudinal direction (horizontal direction). The support body 8 which is a knife slides, maintaining contact with the resin layer 3 of the mother glass resin laminated body 5 by moving in a longitudinal direction. The support body 8 may move in a longitudinal direction, moving upward, and may move in a longitudinal direction without moving upward. By the self weight of the mother glass resin laminate 5, the tensile stress acting on the mother glass resin laminate 5, and the frictional force with respect to the mother glass resin laminate 5 when the support body 8 moves, the support body (8) cuts the resin layer 3 and the adhesive layer 4 (refer to FIG. 8). At this time, since the front-end|tip part of the support body 8 passes through the clearance gap 13 of the glass sheet 2, the cut end surface of the glass sheet 2 is not impaired. Then, as shown in FIG. 9, the support body 8 descends and returns to a stand-by position. Two glass resin laminates 1 formed by cutting the mother glass resin laminate 5 remain on the mounting table 7 .

Thereafter, the glass resin laminate 1 may be subjected to a finishing process such as a polishing process and a cleaning process. Moreover, it is also possible to manufacture the smaller glass resin laminated body 1 by making the said two glass resin laminated bodies 1 into the new mother glass resin laminated body 5, repeating a cutting process similarly to the above.

According to the manufacturing method of the glass resin laminate 1 by this embodiment demonstrated above, the mother glass resin laminate 5 is curved by the support body 8, and bending stress is given to the glass sheet 2, By forming the initial crack 10 in this glass sheet 2 with the crack provision member 11, this glass sheet 2 is cut along the cut line 12. As shown in FIG. Thereby, the split cross-section of the glass sheet 2 can be comprised in a favorable shape. Since the cutting|disconnection of the glass sheet 2 is performed before cutting|disconnection of the resin layer 3, the glass sheet 2 is not damaged by cutting|disconnection of the resin layer 3. In addition, this method can cut the mother glass resin laminate 5 simply and quickly without going through a complicated process such as photolithography. Thereby, the manufacturing cost of the glass resin laminated body 1 can be reduced as much as possible.

In addition, if bending stress is applied to the glass sheet 2 by composing the support body 8 with a knife and supporting the mother glass resin laminate 5 with this support body 8, the resin layer 3 immediately after the cleavage. ) can be implemented by cutting Thereby, it becomes possible to cut|disconnect the mother glass resin laminated body 5 quickly. Moreover, when the support body 8 cut|disconnects the resin layer 3, by sliding this support body 8 with respect to the resin layer 3, the resin layer 3 can be cut|disconnected accurately and quickly.

10-16 show 2nd Embodiment of the manufacturing method of a glass resin laminated body. In this embodiment, the structure of the cutting device 6 differs from 1st Embodiment. Although the support body 8 was comprised by the knife in the 1st embodiment, in this embodiment, the cutting device 6 is comprised separately from the support body 8 movable in the up-down direction, and the support body 8, and the said support body ( 8) has a knife (cutting tool) 14 disposed at an upper position.

The support body 8 is comprised in the cylindrical shape. With this structure, the support body 8 has the support surface of the curved-surface shape which can support the mother glass resin laminated body 5. As shown in FIG. The support 8 has, at its upper portion, a groove portion 8a into which the knife 14 can be inserted. The knife 14 is configured to be movable in the vertical direction in a state in which the blade is directed downward. The other configuration is the same as in the first embodiment, and in the second embodiment, the same reference numerals as in the first embodiment are given to components common to the first embodiment.

In order to cut the mother glass resin laminate 5 by the cutting device 6 of the above configuration, the support 8, the crack imparting member 11 and the knife 14 are arranged at a predetermined standby position (Fig. 10). And in FIG. 11), after loading the mother glass resin laminated body 5 on the mounting table 7, a part of the mother glass resin laminated body 5 is pressed by each pressing member 9a, 9b. In this case, the mother glass resin laminated body 5 is mounted on the said mounting table 7 similarly to 1st Embodiment so that the resin layer 3 may contact the mounting surface 7a of the mounting table 7 . do.

Then, as shown in FIG. 12, while raising the support body 8 from a stand-by position and letting the slit 7b of the mounting table 7 pass, it is made to protrude upward from the mounting surface 7a. Thereby, the support body 8 lifts up a part (central part) of the mother glass resin laminated body 5. By being supported by the support body 8, the mother glass resin laminated body 5 curves so that it may become convex upward. Accordingly, bending stress is applied to the glass sheet 2 .

Then, the crack provision member 11 in a standby position is moved, it arrange|positions on the cut line 12 of the glass sheet 2, it is made to fall, and is made to contact the glass sheet 2 . Accordingly, an initial crack 10 is formed in the glass sheet 2 (see FIG. 13 ). By the action of the bending stress imparted to the glass sheet 2 , the initial crack 10 advances along the cut line 12 . Accordingly, the glass sheet 2 is cut along the cut line 12 . Thereafter, the crack imparting member 11 rises and returns to the standby position (see Fig. 14).

Next, as shown in FIG. 15, the knife 14 in a standby position descend|falls and cut|disconnects the resin layer 3. At this time, the knife 14 comes into contact with the resin layer 3 through the clearance gap 13 produced by the cleavage of the glass sheet 2 . For this reason, the knife 14 does not damage the cut end surface of the glass sheet 2 . At the time of cutting, the knife 14 may be moved in the longitudinal direction, and it may slide with respect to the resin layer 3 . Since the knife 14 is inserted into the groove part 8a of the support body 8 when cut|disconnecting the resin layer 3, it does not contact the support body 8. As shown in FIG. After cutting the resin layer 3, the knife 14 rises and returns to the standby position. By the above, the mother glass resin laminated body 5 is cut|disconnected, and the glass resin laminated body 1 of 2 sheets is manufactured (refer FIG. 16).

17-20 show 3rd Embodiment of the manufacturing method of a glass resin laminated body. In this embodiment, the structure of the cutting device 6 differs from 1st Embodiment and 2nd Embodiment. In 2nd Embodiment, although the cutting device 6 had the support body 8 provided with the groove part 8a, and the knife (cutting tool) 14 arrange|positioned at the upper position of the said support body 8, in this embodiment It has the support body 8 provided with the hole part 8b, and the knife (cutting tool) 14 arrange|positioned below the said support body 8.

The support body 8 is comprised in the columnar shape, and has the support surface of the curved-surface shape which can support the mother glass resin laminated body 5. The support 8 has a hole 8b through which the knife 14 can pass. The hole 8b penetrates in the radial direction of the support body 8 . The penetration direction of the hole 8b coincides with the up-down direction (vertical direction). The knife 14 is configured to be movable in the vertical direction in a state in which the blade is directed upward. The other structures are the same as those of the first and second embodiments, and in the third embodiment, components common to the first and second embodiments are denoted by the same reference numerals as those of the first embodiment.

In order to cut the mother glass resin laminate 5 by the cutting device 6 of the said structure, the support body 8, the crack provision member 11, and the knife 14 are arrange|positioned at predetermined standby positions (FIG. 17). In reference), after loading the mother glass resin laminated body 5 on the mounting table 7, a part of the mother glass resin laminated body 5 is pressed by each pressing member 9a, 9b. In this case, as for the mother glass resin laminated body 5, similarly to 1st Embodiment and 2nd Embodiment, the said mounting table so that the resin layer 3 may contact the mounting surface 7a of the mounting table 7 (7) is loaded.

Next, as shown in FIG. 18, while raising the support body 8 from a stand-by position and letting the slit 7b of the mounting table 7 pass, it is made to protrude upward from the mounting surface 7a. Thereby, the support body 8 lifts up a part (central part) of the mother glass resin laminated body 5. By being supported by the support body 8, the mother glass resin laminated body 5 curves so that it may become convex upward. Accordingly, bending stress is applied to the glass sheet 2 .

Thereafter, the crack imparting member 11 in the standby position is lowered and brought into contact with the glass sheet 2 . Accordingly, an initial crack 10 is formed in the glass sheet 2 (see FIG. 18 ). By the action of the bending stress imparted to the glass sheet 2 , the initial crack 10 advances along the cut line 12 . Accordingly, the glass sheet 2 is cut along the cut line 12 . Thereafter, the crack imparting member 11 rises and returns to the standby position (see Fig. 19).

Then, as shown in FIG. 19, the knife 14 in a stand-by position rises and cuts the resin layer 3. At this time, while the knife 14 is inserted into the hole 8b of the support body 8 from the lower side, the front-end|tip part contacts the resin layer 3 . As the knife 14 rises further, the resin layer 3 is cut|disconnected. At this time, you may move the knife 14 in a longitudinal direction, and may make it slide with respect to the resin layer 3 . Since the knife 14 is inserted into the hole 8b of the support body 8 when cut|disconnecting the resin layer 3, it does not contact the support body 8. As shown in FIG. After cutting the resin layer 3, the knife 14 descends and returns to the standby position. After that, the support body 8 descends and returns to the standby position. By the above, the mother glass resin laminated body 5 is cut|disconnected, and the glass resin laminated body 1 of 2 sheets is manufactured (refer FIG. 20).

Specifically, as shown in FIG. 21 , the glass resin laminate 1 has a first resin layer 3a laminated on one side of the glass sheet 2 and the other side of the glass sheet 2 . The second resin layer 3b, the first adhesive layer 4a for bonding the glass sheet 2 and the first resin layer 3a, and the agent for bonding the glass sheet 2 and the second resin layer 3b It has 2 adhesive layers 4b.

The mother glass resin laminate 5 for manufacturing the said glass resin laminate 1 has an area smaller than the area of the glass sheet 2 on both surfaces of the glass sheet 2 of a base, as shown in FIG. It is formed by laminating|stacking the 1st resin layer 3a and the 2nd resin layer 3b which have. Since the glass sheet 2 is larger than each of the resin layers 3a and 3b, the glass sheet 2 has a portion (protrusion) 15 protruding outward from the end of each of the resin layers 3a and 3b at one end thereof. ) has

Specifically, the cutting device 6 includes a support body 8 configured as a knife, a crack imparting member 11, and a plurality (two pairs in the example of the figure) which is a support member of the mother glass resin laminate 5 . It has a pair of rollers 16a, 16b. The cutting device 6 arrange|positions the support body 8 above the mother glass resin laminated body 5, and arrange|positions the crack provision member 11 below the mother glass resin laminated body 5, and is comprised.

In order to cut the mother glass resin laminate 5 by the cutting device 6 having the above configuration, the mother glass resin laminate 5 is held by the pair of rollers 16a and 16b (napping), and then in the standby position. The existing support body 8 is moved downward, and the 2nd resin layer 3b of the mother glass resin laminated body 5 is made to contact. Moreover, when the support body 8 is moved downward, the mother glass resin laminated body 5 is pushed down by the support body 8, as shown by the dashed-dotted line in FIG. curved

Thereafter, the crack imparting member 11 rises while maintaining this curved state, and comes into contact with the glass sheet 2 of the mother glass resin laminate 5 to form the initial crack 10 . At this time, the crack imparting member 11 is in contact with the protrusion 15 in the glass sheet 2 of the mother glass resin laminate 5 . Accordingly, the crack imparting member 11 can form the initial crack 10 in the glass sheet 2 without contacting the second resin layer 3b. This initial crack 10 is advanced along the cut line 12 to cut the glass sheet 2 . Thereafter, the support body 8 is moved downward and in the longitudinal direction to slide with respect to the second resin layer 3b to cut the second resin layer 3b. Thereafter, the first resin layer 3a is cut in the same manner. By the above, the mother glass resin laminated body 5 is cut|disconnected, and the glass resin laminated body 1 of 2 sheets is manufactured.

24 to 27 show another example of a glass resin laminate and a mother glass resin laminate. In the example shown in FIG.24 and FIG.25, the glass resin laminated body 1 has two-layered glass sheet 2a, 2b and two-layered resin layer 3a, 3b. Specifically, the glass resin laminate 1 and the mother glass resin laminate 5 are fixed to one side of the first glass sheet 2a and the second glass sheet 2b and the first glass sheet 2a. The 1st resin layer 3a, the 2nd resin layer 3b provided between the other surface of the 1st glass sheet 2a, and the 2nd glass sheet 2b, the 1st glass sheet 2a, and the 1st glass sheet 2a A first adhesive layer 4a for adhering the first resin layer 3a, a second adhesive layer 4b for adhering the other surface of the first glass sheet 2a to the second resin layer 3b, and a second number It has a 3rd adhesive layer 4c which adhere|attaches the base layer 3b and the 2nd glass sheet 2b.

In addition, the 1st glass sheet 2a of the mother glass resin laminated body 5 has the protrusion part 15 in the edge part similarly to 3rd Embodiment. The second glass sheet 2b of the mother glass resin laminate 5 does not have the protrusion 15 . In order to cut|disconnect this mother glass resin laminated body 5, after cutting the 2nd glass sheet 2b, it is preferable to cut the 1st glass sheet 2a.

In the example shown in FIG. 26 and FIG. 27, the glass resin laminated body 1 has two-layered glass sheet 2a, 2b, and three-layered resin layer 3a-3c. Specifically, the glass resin laminate 1 and the mother glass resin laminate 5 are a first glass sheet 2a and a second glass sheet 2b, and a first resin layer 3a to a third resin layer ( It has 3c) and the 1st contact bonding layer 4a - 4th contact bonding layer 4d which mutually adhere|attach each glass sheet 2a, 2b and each resin layer 3a-3c.

27, the 1st glass sheet 2a of the mother glass resin laminated body 5 has the part (1st protrusion part) 15a which protrudes outward rather than the edge part of each resin layer 3a-3c. . The 2nd glass sheet 2b of the mother glass resin laminated body 5 has the part (2nd protrusion part) 15b which protrudes outward rather than the edge part of each resin layer 3a-3c. The protrusion length L1 of the first protrusion 15a is greater than the protrusion length L2 of the second protrusion 15b. Thus, by making the protrusion lengths L1 and L2 of each protrusion part 15a, 15b different, it becomes easy to form the initial stage crack 10 in the 1st glass sheet 2a and the 2nd glass sheet 2b. Therefore, it becomes possible to cut|disconnect the glass sheet 2 efficiently.

28-30 show 5th Embodiment of the manufacturing method of a glass resin laminated body. Like 1st Embodiment, the mother glass resin laminated body which concerns on this embodiment is the glass sheet 2 of 1 layer, the resin layer 3 of 1 layer, the glass sheet 2, and the resin layer 3 similarly to 1st Embodiment. An adhesive layer 4 for bonding the In this embodiment, the area of the resin layer 3 is larger than the area of the glass sheet 2 . Accordingly, the peripheral portion of the resin layer 3 protrudes from the glass sheet 2 . Specifically, the end portion 3d of the resin layer 3 protrudes from the end portion 2c of the glass sheet 2 .

A pair of mounting tables 7 in the cutting device 6 are comprised so that movement in a horizontal direction is possible. That is, the cutting device 6 holds one end of the mother glass resin laminate 5 by the pressing member 9a corresponding to the one mounting table 7, and the other mounting table 7 and corresponding The other end of the mother glass resin laminate 5 is held by the pressing member 9b. The cutting device 6 makes the tensile force F act on the mother glass resin laminated body 5 by moving so that a pair of mounting tables 7 may be mutually separated in this holding state. Thereby, tensile stress can be applied to the cutting|disconnection direction (advance direction of the support body 8) and the direction perpendicular|vertical to the cut|disconnection plan part (part supported by the support body 8) of the mother glass resin laminated body 5.

Hereinafter, the manufacturing method of the glass resin laminated body 1 by this embodiment is demonstrated.

28 : shows the cutting apparatus 6 after the cutting process of the glass sheet 2. A gap 13 by cutting is formed in the glass sheet 2 of the mother glass resin laminate 5 . The support body 8 also serving as a knife supports the resin layer 3 of the mother glass resin laminate 5 . The cutting device 6 raises the support body 8 from this state, and makes a pair of mounting table 7 separate in a horizontal direction together with press member 9a, 9b.

Thereby, the resin layer 3 is stretched|stretched by the mounting table 7 and the support body 8, and is plastically deformed. Thus, when the resin layer 3 extends|stretches, the clearance gap 13 formed in the cutting process of the glass sheet 2 becomes still larger. Therefore, when cut|disconnecting the resin layer 3 with a knife (support body 8), the said knife becomes difficult to contact with the glass sheet 2.

As shown in FIG. 29, when the stretched resin layer 3 is cut|disconnected with a knife, as shown in FIG. 30, the edge part 3e of the resin layer 3 formed by the said cutting|disconnection is the glass sheet 2 ) to protrude from the end (2d). In addition, the protruding part 3a1 of the resin layer 3 protruding from the edge part 2d of the glass sheet 2 is laminated with the glass sheet 2 in the resin layer 3 by the plastic deformation mentioned above. It is thinner than the thickness of 3a2). The glass resin laminate 1 formed by the above can protect the periphery of the said glass sheet 2 by the resin layer 3 protruded from the glass sheet 2 .

In this embodiment, although the example in which the resin layer 3 is stretched|stretched by the raising of the support body 8 and movement of the mounting table 7 was shown, it is not limited to this structure. The process of stretching the resin layer 3 may be performed only by the raising of the support body 8 or only by the movement of the mounting table 7 . Further, the resin layer 3 may be stretched by lowering the mounting table 7 together with the pressing members 9a and 9b. In addition, the cutting device 6 may be equipped with the clamping mechanism which can hold|grind the mother glass resin laminated body 5, and you may stretch the resin layer 3 with the said clamping mechanism. Although the example in which the resin layer 3 is stretched so that it may plastically deform is shown in this embodiment, it is not limited to this, You may stretch and cut the resin layer 3 to the extent which elastically deforms. In this case, after cutting|disconnecting the resin layer 3, the edge part 3e of the resin layer 3 is freed by performing grinding etc. process to the edge part 2d of the glass sheet 2 in a cut part. It can protrude from the end 2d of the seat 2 .
