Is set to be smaller than the total thickness of the glass plate 1, the synthetic resin plate 8, and the sheet adhesive 11 in the free state, and as shown in FIG. And the synthetic resin plate 8 is a sheet-like adhesive 11
When it is sandwiched together, the glass plate 1 and the synthetic resin plate 8 bend and the adhesive layer 6 having rubber-like elasticity contracts. As a result, the glass plate 1 and the synthetic resin plate 8 bend in a direction floating from the adhesive layer 6 on the rear side in the traveling direction of the glass plate 1 and the synthetic resin plate 8 with respect to the rollers 12 and 13 as the pressing units. Therefore, the adhesive layer 6 and the glass plate 1 and the synthetic resin plate 8
The glass plate 1 and the synthetic resin plate 8 are bonded via the sheet-like adhesive 11 in a state in which bubbles are continuously expelled from the interface with the glass plate 1.

ら接合作業を行っても支障はない。The glass plate 1 and the synthetic resin plate 8 held between the rollers 12 and 13 are bent from the holding portion in the direction in which the rear side of the plate-like body in the traveling direction rises from the adhesive layer 6, but the adhesive layer 6 by its own weight. Therefore, the glass plate 1 and the synthetic resin plate 8 are supported by a support roller 14 as a support member, and the support roller 14 is moved toward the rollers 12 and 13 together with the glass plate 1 and the synthetic resin plate 8. It is preferable to move it so that it becomes gradually lower. In the case where the support roller 14 is provided, there is no problem even if the joining operation is performed from a state where the release film 2 is completely removed in advance.

Since the glass plate 1 and the synthetic resin plate 8 are joined via the adhesive layer 6, compared with a configuration in which the rollers are rolled while pressing the glass plate 1 and the synthetic resin plate 8, a long laminate is used. The roller driving mechanism is simplified when forming.

May be used to continuously laminate the glass plates 1. For the core material 10, for example, a biaxially stretched polyethylene terephthalate film is used. The rollers 12 and 13 are disposed at predetermined positions so that their rotation axes extend vertically, and the glass plate 1 and the adhesive 15 are moved not vertically but vertically (vertically). You. When receiving a force that bends away from the adhesive layer 6 due to the pressing force of the rollers 12 and 13 in a horizontally disposed state, there is a possibility that the force may overcome the force by its own weight and come into contact with the adhesive layer 6. However, when the glass plate 1 is bent by being pressed by the rollers 12 and 13 while being held vertically, the glass plate 1 is held on the side away from the adhesive layer 6 to float the plate-like body from the adhesive layer 6. No member such as the roller 14 is required. In this case, since the laminated bodies are formed in a state of being connected via the core material 10, the transportation is facilitated, and the productivity is further improved.
