Antileak suture structure, method for forming anti leakage suture structure and heat treatment apparatus for suture structure

摘要

The invention relates to a suture structure having an antiwaterproof and anti leaky stitching suitable for a three-dimensional product processing product such as shoes, and a method of forming the same. In the suture structure of the present invention, the surface material and the backside material are sutured along the suture line through the hot-melt adhesive resin layer, and the sealant hole forming the suture line is filled with a part of the resin of the hot-melt adhesive resin layer, and the surface material is waterproof Is characterized in that This suture structure can be prepared in a manner that includes the following (a) and (b) steps: (a) the pretensioned suture layer structure is sewn together with at least a specific hot melt adhesive resin sheet sandwiched between the waterproof surface material and the backside material A high frequency voltage is applied to melt the hot melt adhesive resin sheet while applying the high frequency voltage to melt the hot melt adhesive resin sheet while pressing the front suture layer structure by the surface of a specific pressure plate body, and fluidizing the hot-melt adhesive resin sheet The needle hole of the suture line is filled in. Sutures of the inventionEmbodiments of the method of forming the structure are disclosed together with a high-frequency heating apparatus suitable for processing shoes.
