[0002] Laminated glass mainly utilizes the function of the PVB adhesive layer to absorb medium and low frequency sound waves to control the propagation of sound wave energy. Its performance is related to the actual thickness of the glass, the thickness of the adhesive film, and the flexibility of the adhesive film. When processing glass, two pieces of glass need to be coated with glue and then laminated. The two laminated pieces of glass form one layer, and then the laminated glass in multiple layers is stacked on the kettle rack and heated in the kettle to reach the state of glue dissolution, so that the two pieces of glass are glued together.

[0003] In the prior art, usually after the glass is heated, the glass is pressed by a pressing roller. Due to the single-point pressing of the pressing roller, the glass cannot be fully pressed, and the two pieces of glass are not firmly glued together, resulting in an included angle between the upper and lower layers of the laminated glass, and thus warping.
