摘要
PURPOSE:To increase welding strength by a method wherein string-shaped materials of rough network sheet are shifted and arranged so that one of them is not put on another, high frequency sewing is carried out and the sheets are welded through a lot of point contacts. CONSTITUTION:String-shaped material having no high frequency welding nature is arranged crosswisely and woven to get a sheet of relatively rough network. This sheet is dipped in polymer solution having high frequency welding nature squeezed, dried and gelled. This rough network sheet 1 capable of high frequency sewing and the adjacent sheet 2 of the same kind are shifted to each other and arranged so that string-shaped materials of the respective sheets are not put on each other. The selvage parts of both adjacent sheets are piled on each other or folded and the jointed part is sewed vertically by high frequency. In this method it is possible to obtain a sheet wherein its joint part is strong and which is tough and free of cracks overall.
