る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIG.
It will be described with reference to FIG. The belt 1 used in the interlining machine for sewing is heat resistant, and the woven fabric made of glass fiber, polyamide fiber, aromatic aramid fiber, etc. is sufficiently impregnated with fluororesin, and then baked at high temperature. ing. As shown in FIGS. 1 and 2, slanted surfaces 2 that are slanted in the thickness direction are provided on both end surfaces in the running direction of the belt 1 by polishing. When the belt 1 is looped and these slanted surfaces 2 are overlapped with each other, the overlapping portions are provided such that the thickness of the overlapping portion is the same as the thickness of the belt 1 other than the slanted surface 2. Are joined together by heat fusion.

けられている。Further, the back reinforcing material 3 is attached by heat fusion to cover the boundary formed by overlapping the slanted surface 2 on the back surface of the belt 1, and the belt 1 is pulled in the running direction of the belt 1. Is preventing. Further, the surface of the belt 1 covers the boundary formed by both ends of the belt 1 and has a thickness of 0.02.
A 5 mm PFA film 4 is attached. Since this PFA film has a thin thickness of 0.025 mm, it has almost no effect on the bonding strength and is provided to improve the design surface.

Also in the conventional butt joint, the PFA film having the same thickness is attached so as to cover both ends of the joint as in the present embodiment. Further, the strength corresponds to each case where the thickness of the belt and the thickness of the back reinforcing material are changed.

度を得ることができる。As is apparent from Table 1, the endless belt 1 formed by the joint method of this embodiment has a higher strength against the pulling force. Further, unlike the conventional case, when the parts are heated and pressed using the belt of this embodiment, the parts of the belt 1 are not wrinkled because the surface of the belt 1 has no unevenness. Further, since the joint surfaces at both ends of the belt 1 in the traveling direction are wider than the butt joint, stronger strength can be obtained.
