FIELD: textile, paper.
SUBSTANCE: invention relates to the methods of technical fabrics seam area ultrasonic welding, using the textured sonotrode and/or a support. The fabric edges are overlapped, like woven, or one or both of the edges may have several loose warp or weft threads. The method includes connecting of fabric overlapped edges by means of ultrasound, thickness reduction of two edges placed one above each other up to the cloth thickness of the fabric itself.
EFFECT: connected area can be perforated, using the laser or other mechanical means to create the seam, having the same woven texture and permeability as the fabric cloth.
