Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for manufacturing bathroom shoes, and an embodiment thereof will be described with reference to the drawings. The material to which the foam membrane 2 is formed and adhered is cut to form a shell piece 3 having a ■-shape, and a foam membrane 5 is placed on the back surface of the thermoplastic soft synthetic resin sheet 4 on the back side of the inner peripheral edge of the foam membrane piece 3. The edging tape 6 made of a material to be adhered is polymerized with its back side facing outward, and in this polymerized state, the inner peripheral edge of the edging piece 3 and the inner periphery of the edging tape 6 are welded (not shown). After burning and welding each other with
Then, both ends of the folded edge tape are superposed so that the back side of the edge piece 3 and the front surface of the edge tape 6 are on the outside. are burnt and welded to each other using a welder (not shown), and then the whole is turned over so that the front and back sides are reversed, and the hemming tape 6 is folded downward to form the sash member 7.

Next, separately from this, a core material 10 made of sponge is placed on the upper side of the lower skin piece 9 made of a thermoplastic soft synthetic resin sheet to which a reinforcing piece 8 made of a thermoplastic soft synthetic resin material is previously welded to the lower heel part. After superposing the epithelial pieces 11 made of thermoplastic soft synthetic resin sheets on the upper side of the core material 10, the entire peripheries of the lower skin piece 9 and the epithelial piece 11 are welded together using a welder (not shown) to form the bottom member 12. The above-mentioned lace member 7 is placed on the bottom member 12, and the entire periphery of the bottom member 12 and the lace member 7 are placed on top of the bottom member 12.
The finished product A is obtained by burning and welding the entire lower edges of the two together using a welder (not shown).

Since the present invention is as described above, it is of course possible to complete bathroom shoes whose foot openings are reinforced with hemmed tape through extremely simple steps. The material is cut to form a V-shaped piece, and a edging tape made of thermoplastic soft synthetic resin material is placed on the back side of the inner peripheral edge of this piece of piece, with the back side facing outward, and then polymerized. In this polymerized state, the inner circumferential edge of the edging tape and the inner periphery of the edging tape are welded to each other by a welder, and then the edging tape is folded back, and both ends of the edging tape in this folded state are attached to the edging tape. Polymerize so that the back side of the piece and the surface of the edging tape are on the outside, and in this polymerized state, both ends of the edging piece and the edging tape are welded to each other with a welder, and then the whole is turned over so that the front and back sides are turned over. Since the edging tape was turned downward at the same time as it was turned, the edging tape once protruded upward in a cylindrical shape, and then was turned back downwards. In addition, the welded part between the hemming tape and the welding piece is hidden from the outside by the folding of the hemming tape, so that it does not look ugly, and the welding part is also secured between the hemming tape and the welding piece. It is constructed by welding both ends of each piece and then turning it over so that most of the welding marks are exposed outside as protrusions, except for a part of the welded parts. Therefore, there is an advantage that there is no risk of the protrusions solidifying and injuring limbs etc. during the cold winter season.

Claims (1)

[Claims] 1 A thermoplastic soft synthetic resin material is cut to form a ``■-shaped'' piece, and a edging tape made of a thermoplastic soft synthetic resin material is attached to the back side of the inner peripheral edge of this ``skin'' piece so that the back side is on the outside. In this polymerized state, the inner periphery of the edging tape and the inner periphery of the edging tape are welded together using a welder, and then the edging tape is folded back to form the edging piece and the folded edging. Both edges of the tape are polymerized so that the back side of the lining piece and the surface of the edging tape are on the outside, and in this polymerized state, both ends of the lining piece and the edging tape are welded to each other with a welder, and then the whole is assembled. The hemming tape is rolled up so that the front and back sides are reversed, and the hemming tape is rolled downward to form a shank member. Separately, a core material is also placed on top of a lower skin piece made of a thermoplastic soft synthetic resin material. After each epithelial piece made of a thermoplastic soft synthetic resin material is polymerized on the core material, the entire periphery of the lower skin piece and the epithelial piece are welded together using a welder to form a bottom member, and the above-mentioned material is placed on top of this bottom member. 1. A method of manufacturing bathroom shoes, which comprises: placing a lace member on the sole and welding the entire periphery of the sole member and the entire lower periphery of the lace member to each other using a welder.
