Abstract

PURPOSE:To produce a product of beautiful appearance by a method in which the board core having silver foils on the surface which is to be in contact with said sheet for an outer surface is arranged in between the resin sheets for an inner surface and an outer surface, and parts are placed on the positions of the sheet for inner surface corresponding to the silver foils, thereby sticking them mutually by high frequency welding. CONSTITUTION:Into the space between the sheet 1 for an outer surface and the sheet 2 for an inner surface made of thermopolastic synthetic resin, a board core 3 covered with a silver foil 3' on its surface which is to be in contact with said sheet for outer surface, is inserted. The parts 8 composed of thermoplastic synthetic resin and provided with welding zones 7, are arranged, and said welding zones 7 are lapped on the outer surface of the position corresponding to said silver foils on the sheet for inner surface. An upper electrode 9 and a lower electrode 16 are respectively attached to the outer side of the welding zone and to the outer side of the sheet for inner surface and high frequency voltage is applied to both electrodes while pressurizing, thereby welding mutually the outer surface of the sheet for inner surface and the inner surface of the welding zone. Thus, the product without push marks on the outer surface of the sheet for outer surface may be obtained.

Between the circular sheet of the interior (2) A cardboard core covered with a thin film of metal foil such as silver or copper or a coating film of the same metal on all or a designated part of the surface in contact with the outer sheet. In a semi-finished product that includes a plate-shaped part made by inserting, a part with a welding margin made of two thermoplastic synthetic resin sheets is placed on the inside of the plate-shaped part, and the welding margin is applied to the inner sheet. The outer surface of the above-mentioned thin film C at the point where the two windows are to be bonded (the two upper electrodes are applied to the outside of the outer sheet (-the outer side of the outer sheet) and the lower electrode is pressed, and then the upper and lower electrodes are pressed together. The gist of this method is to apply a high frequency voltage to the inner sheet and weld the outer surface of the inner sheet and the inner side of the welding margin to each other.

ーである。Hereinafter, embodiments of the present invention will be described with reference to Drawing C2 (-
1. First, a gap is formed between the outer sheet (1) made of thermoplastic synthetic resin having a foam layer (not shown) on the back surface (2) and the inner sheet (2) of the interlayer without a foam layer on the back surface (2). the outer surface) (
Silver foil (
3) After sandwiching the cardboard core (3) coated with ' and the cardboard core (4) not coated side by side, insert the inner and outer surfaces (21+11) along its entire periphery and the cardboard core +3+
(4) High-frequency welding is performed at the interval ζ2 to form a semi-finished product (5) of a cover for a calculator with a core that can be folded freely in two, and then silver foil (3)' is applied to the semi-finished product (5). Inside the plate-like part (6) on the side that includes the adhered cardboard core (3), press a band-shaped calculator (not shown) equipped with a welding margin (7) made of a double-coated plastic synthetic resin sheet. Supporting parts (8) (8)'
The outer surface of the part corresponding to the silver foil (3)' in 21 (21) is overlapped and the welding margin (outside of 71 (2 upper electrode (9) (Apply the two lower electrodes on the outside of 11 and apply pressure to both the upper and lower electrodes +9.) This calculator cover is completed by lava lava and the inner surface of the welding margin (7).

ものである。Since the present invention is as described above, the high frequency welding function is achieved by the action of the metal thin film adhered to the cardboard core C2, which connects the upper electrode and the metal thin film as shown with dots in FIG. 4C2. The process is concentrated between As shown by the dots in Figure 7, the finished product is manufactured using the conventional manufacturing method, in which the outer sheet melts and is crushed under pressure because the high-frequency welding function is performed between the upper and lower electrodes. (The same reference numerals as in the above embodiments are attached.) This prevents the production of unsightly products with unsightly so-called press marks (weld marks) α1 on the outer surface of the outer sheet. It is effective.
