FIELD: process engineering. ^ SUBSTANCE: invention relates to method of jointed coated fabrics together and bag made thereof. Coated fabric have polymer fibers stretched along one axis. Proposed fabric is coated by heat-sealing layer of thermoplastic polymer material with fusion point lower than crystallisation/fusion point of aforesaid fibers. Two coated fabric are arranged one above the other with their heat-sealing layers located face-to-face. At least, one coated fabric is heated on the side of polymer fibers stretched along one axis to temperature below crystallisation/fusion point of aforesaid fibers to fuse heat-sealing layers. ^ EFFECT: simplified heat-sealing, higher strength of joint. ^ 14 cl, 6 dwg |
