Abstract:
A seamed structure formed with seams which are soak- and leak-resistant to be suitable for three-dimensionally shaped, processed products such as shoes and the like, and a method of forming the same. The seamed structure has a feature in that a face material and a back material are seamed along seam lines through a hot melt adhevise resin layer, sewing needle holes defining the seam lines are filled with a part of a resin of the hot melt adhesive resin layer, and the face material is water-proof. The seamed structure can be prepared by a method which includes the following processes: (A) a process of preparing a precursor seamed layer structure by sewing the water-proof face material and the back material at least along the seam lines with a specified hot melt adhesive resin sheet between them; (B) while pressing the seamed layer structure by means of surfaces of a specified pressure plate body, applying sufficient high-frequency voltage to melt the hot melt adhesive resin sheet, thus fluidizing only the hot melt adhesive resin sheet and having a part of the resin sheet enter and fill into the sewing needle holes which constitute the seam lines. An embodiment of a method of forming the seamed structure is disclosed together with a high-frequency heating processing device, which is suitable for processing of shoes.
