摘要

A simplified method for making an impermeable joining on three-layer or bi-layer fabric materials, either with or without a complex construction on a joining side thereof, and being preliminarily joined by a stitching or ultrasound joining arrangement, wherein said method comprises only two method steps, a first joining step of joining two fabric material panels and a second impermeabilizing step carried out by cauterizing and sealing a strip element, and being performed by a single machine in a single operation thereof.
