FIELD: haberdashery. SUBSTANCE: method involves applying heated thermosensitive material to movable substrate to form teeth. Movable substrate may be brought away from heated material applying point at an angle to substrate. By changing substrate and heated material feeding speed difference in the process of applying the material and by changing angle between substrate and point of applying heated thermosensitive material, fastening characteristics may be changed, particularly, shearing strength of fastener formed by teeth. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 12 cl, 9 dwg, 4 tbl
