There are inventions and ideas in Publication No. 55-73522 and Publication of Utility Model Publication No. 49-32637.
これら公知技術により、発泡樹脂シート相互を
溶着した場合、第５図に示す現象が生じている。 When foamed resin sheets are welded together using these known techniques, the phenomenon shown in FIG. 5 occurs.

着部３が隆起し、分厚くなる。 For example, as shown in Fig. 5A, foamed resin sheets 1 and 2
When the edges of the foamed resin sheets 1 and 2 are overlapped and welded together, the welded part 3 becomes thicker than the other parts, and the end faces of the foamed resin sheets 1 and 2 are butted against each other and welded as shown in Figure B. In this case, the welded portion 3 also bulges and becomes thick.
第５図Ｂにおいて、溶着部３の隆起を緩和すべ
く突合力を小さくすると、溶着状態が不十分とな
り、その後の取り扱い中、溶着部３に亀裂などが
生じやすい。 In FIG. 5B, if the butt force is reduced in order to reduce the protrusion of the welded part 3, the welded state becomes insufficient, and cracks are likely to occur in the welded part 3 during subsequent handling.

樹脂シート相互の満足な溶着が期待できない。 Another practice has been to place a foamed resin sheet on a table and butt and weld the edges of these sheets, but in this case as well, a bump occurs in the welded part 3, and the edge of the sheet is flipped up by the table edge. Unexpected situations such as these have occurred, and satisfactory welding of the foamed resin sheets to each other cannot be expected.

化もはかれる。"Operation" In the case of the device of the present invention, while each foamed resin sheet is being held under suction by a pair of tables, the edges of these foamed resin sheets are trimmed by a cutting machine and a cutting auxiliary machine, and the trimmed foamed resin sheets are After the edges are heated and softened by a heating machine, the table is moved in the direction of abutting these sheets, and the edges of each foamed resin sheet are abutted against each other, thereby making it possible to weld the sheets with sufficient strength, and also to avoid any additional heat during welding. By sandwiching the welded portion of the foamed resin sheet between a pressure machine and a pressure receiver and applying appropriate pressure, it is possible to prevent the welded portion from protruding.In addition, each necessary process can be performed continuously, streamlining work. It is measured.

縁を加熱軟化し、接着性をもたせる。 Next, the edges of the cut foamed resin sheets 32A, 32B are heated and softened using the heaters 24A, 24B. During heating, the heater 30 is raised to a predetermined position via the cylinder 31 as shown in FIG. After that, the tables 12A and 12B are moved by the cylinders 15 in the directions of arrows X1 and X3 in FIG. Heat it to soften it and make it adhesive.

により降下させて当該シート突合部を加圧する。 Thereafter, the heaters 30 of the heaters 24A, 24B are lowered to their original positions, and the tables 12A, 12B are further moved in the directions of the arrows X1, X3 as shown in FIG. During this butting, the pressure receiving plate 25 is raised by the cylinder 26 of the pressure receiving machine 22 and applied to the lower surface of the sheet abutting portion, and the pressure plate 18 of the pressure machine 16 is moved up to the cylinder 19.
to pressurize the sheet abutting portion.

により阻止される。 Thus, the foamed resin sheet 32 is heated and softened.
The edges of the sheets A and 32B are firmly welded by the butting force at this time, and the protrusion of the welded portion that tends to occur during this butting is also prevented by supporting the sheet edge from the back side via the pressure plate 25 and by the pressure plate 18. This is prevented by applying pressure to the area.

帰する。 After welding the edge of the foamed resin sheet, the pressure plate 18 of the pressure machine 16 rises, the pressure plate 25 of the pressure receiver 22 descends and returns to its original position, and the table 12
A and 12B release the suction of each foamed resin heat 32A and 32B and return to the directions of arrows X2 and X4, respectively.
