Abstract

532,643. Seaming non-metallic sheets. ROYAL & CO., T. M. Sept. 18, 1939, No. 26075. Convention date, Oct. 29, 1938. [Class 42 (i)] [Also in Group XVII] A web of paper &c. 1 is united to a lining 2 of thermoplastic material or coated with a layer of same, and the web is then folded into tubular form with the longitudinal edges in abutting relation. A strip 6 of thermoplastic is fed into the tube to cover the abutting edges and is fused thereto by a heater 9 to form a screw A. The tube is cut into bag lengths by rollers 10, 11 and the lengths then enter an end sealing mechanism comprising a number of grips 14 on an endless belt 15 and heating elements 16 which fuse the thermoplastic layer along a transverse zone B to close the end. The bag may be formed with bellow sides.
