呼ばれ、合わせガラスの製造に広く採用されている。In this type of laminated glass, a laminated body having an interlayer film sandwiched between glass plates is generally placed in a rubber bag and vacuum suction is performed to discharge air existing between the glass plate and the interlayer film. Preliminary pressure bonding is performed by heating the laminated body while maintaining this state, and then, the laminated body that has been subjected to this preliminary pressure bonding is subjected to main pressure bonding by heating and pressing in the autoclave. This method is called a vacuum bonding method and is widely used for manufacturing laminated glass.

えば、特公平１−３２７７６号公報参照）。In order to improve the blocking resistance between the interlayer films, the handling workability when sandwiching the interlayer film between glass plates, and the deaerating property in the pre-compression bonding step, the above interlayer films are usually
The embossing having fine irregularities is formed on both surfaces thereof. In particular, the degassing property in the pre-pressing step greatly affects the quality of the laminated glass, and if this degassing is insufficient, bubbles will be generated at the interface between the glass plate and the interlayer film, and the transparency of the laminated glass will be reduced. It gets worse. Therefore, various proposals have been made on the form of embossing with good deaeration (see, for example, Japanese Patent Publication No. 1-32776).

Even if an intermediate film having a desired emboss is used, the degassing passage is narrowed at the interface between the glass plate and the intermediate film, and the air existing at the interface becomes difficult to escape.

Bubbles are generated in the obtained laminated glass due to insufficient deaeration, and the transparency of the laminated glass deteriorates. Such a defect is particularly caused by the productivity of laminated glass (especially, in the case of a preliminary laminated glass), even when a wide laminated glass or a laminated glass having a large curvature whose application has recently been expanded is produced, or when an ordinary laminated glass is produced. This tends to occur when increasing the line speed in the crimping process).

気される。As described above, when the upper chamber 11 and the lower chamber 12 are depressurized to the same degree of vacuum, there is a gap between the upper glass plate 61 and the intermediate film 62, and the lower glass plate 6 is present.
1 and the intermediate film 62 are lightly in contact with each other, and unlike the conventional vacuum bonding method using a rubber bag, at the same time as the vacuum depressurization is started, external pressure is not naturally applied to the laminated body from the outside of the rubber bag. Therefore, not only the air interposed between the upper glass plate 61 and the intermediate film 62 but also the intermediate film 6
The air present between the second glass plate 61 and the lower glass plate 61 is also sufficiently degassed.

い。After that, the knob 41 of the support 40 is operated from the outside to pull it backward (outward of the lower chamber 12) to move the support 40 horizontally in the side wall direction. Then, the upper glass plate 61 of the laminated body 60 is disengaged from the support 40, and the support of the upper glass plate 61 of the laminated body 60 is released, whereby the upper glass plate 61 falls (moves) onto the intermediate film 62. Then, in this state, when the exhaust / air inlet holes 15 of the upper chamber 11 are opened to the atmosphere, the upper chamber 11 naturally becomes atmospheric pressure, and the film or sheet 13 extends toward the lower chamber 12 due to the difference in atmospheric pressure, The laminated body 60 is pressed from above the glass plate 61. At this time, if the film or sheet 13 is difficult to stretch, the voltage of the radiant heater 20 including a plurality of infrared heaters may be adjusted to slightly heat (for example, 50 ° C. or less). Good.

When is heated to a desired temperature, the upper and lower glass plates 61 and the intermediate film 62 are thermocompression bonded and integrated. The heating conditions differ depending on the type of the intermediate film 62. For example, when the intermediate film 62 is made of a plasticized polyvinyl butyral resin sheet, precompression bonding is preferably performed at about 70 to 110 ° C. When the intermediate film 62 is made of an ethylene-vinyl acetate-based resin sheet, the preliminary pressure bonding is not always necessary, and the preliminary pressure bonding step is omitted, and the main pressure bonding is preferably performed directly at about 80 to 120 ° C.

Then, the upper chamber 11 and the lower chamber 12 are separated, the film or sheet 13 is further removed, and the laminate 60 is taken out. The film or sheet 13 is reused if it has no defects such as wrinkles.
Here, when the intermediate film 62 is a plasticized polyvinyl butyral resin sheet, the laminated body 60 is usually sent to the main pressure bonding step and put in an autoclave to about 120 to 150 ° C.
A laminated glass is obtained by subjecting the laminated glass to a high temperature and high pressure treatment at a temperature of about 10 to 15 kg / cm 2 .
