In this method, a laminate with an interlayer film sandwiched between two glass plates is put into a pre-pressurized rubber bag, the vacuum is evacuated, the entire bag is heated, and the glass plates and the interlayer film are bonded together by thermocompression. . However, for example, when manufacturing pie layer type safety glass in which a plastic film is bonded to a glass plate, if the above-mentioned pre-pressed rubber bag method is used, unevenness and wrinkles on the inside of the pre-pressed rubber bag will be removed from the plastic film. A problem was discovered in which the glass was transferred to the surface of the glass, resulting in a serious drawback as a safety glass. In addition, as an improved manufacturing method for the above-mentioned safety glass, a cover glass plate having the same shape as the safety glass manufactured by tA is layered on a plastic film of a laminate of a glass plate and a plastic film, and a pre-pressing rubber bag method, etc. A method of obtaining the above-mentioned type of safety glass by heat-pressing a glass plate and a plastic film or peeling off a cover glass plate using
This is proposed in Publication No. 34. According to this method, thermocompression bonding of thermoplastic films is possible, but

A vacuum system is constructed with the support on which the body is placed, and the vacuum system and the upper chamber above are crimped by vacuum operation and atmospheric air introduction operation, so it is different from conventional lamination. Compared to a method in which a plastic film is sandwiched between a glass plate and a dummy glass plate having the same shape as the glass plate, and the plastic film is placed in a preliminary crimping device and crimped, the crimping work can be simplified and manufacturing costs can be reduced. Furthermore, compared to Japanese Patent Application No. 80-51271, the use of a base film is eliminated, and costs and manpower can be reduced.

However, in the present invention, the above-mentioned defects are transferred to the upper surface of the plate-shaped body on the plastic film side during thermocompression bonding. Since there is no material that binds, a plastic film with good surface quality can be obtained. In particular, as described above, the present invention can significantly reduce wrinkles, unevenness, and optical distortion on the plastic film surface compared to conventional methods, so it can be used for windows of automobiles, other types of transportation vehicles, aircraft, etc. A plastic film that is tear-resistant, scratch-resistant, and, in some cases, puncture-resistant, is attached to the interior side of a single glass plate or laminated glass plate to prevent skin damage to passengers when the glass plate breaks. It is ideal for manufacturing safety glass that requires a high quality surface finish.
