Abstract

887,292. Seaming non-metallic sheet material. METAL BOX CO. Ltd. Sept. 8, 1960 [Dec. 11, 1959], No. 42233/59. Class 42 (1). [Also in Group XVII] A number of connected sleeves are formed in overlying lengths of synthetic plastic film by forming transverse heat seals 7 to define the sleeves, each of which is in the form of a truncated triangle with the open ends 1, 2 of the sleeves formed by the longitudinal edges of the film and by forming a line of weakening 9 parallel to each heat seal 7 to extend from one longitudinal edge of the films to the other to facilitate the removal of one sleeve from the adjoining sleeve. Two lengths 4, 5 of polyethylene film are fed to devices 6 which form the heat seals 7. Perforator devices 8 form openings 9 in the seals 7, the length of the bridge 11 between the openings 9 being of the order of one-quarter that of an opening 9. The endmost openings 10 are intersected by the longitudinal edges of the film to provide a " start " for the removal of a sleeve. The sleeves are formed into a roll 12. The heat-sealing and perforating operations may be performed simultaneously. Alternatively, the lines of weakness may be formed between two adjacent heat seals. The sleeves may be made from tubular material slit lengthwise.
