Abstract

763,254. Making bags. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 10, 1954 [Nov. 25, 1953], No. 32699/53. Class 94(2). [Also in Group VIII] A bag, formed from flexible thermoplastic film is made by heat sealing a flat disc onto the flanged end of a tube. The tube 16 is placed over a former 10 with some stretching so that a part projecting above the former bends in to lie upon it. The disc is placed on the flange so formed and a sealing head heat seals it to the tube. The head comprises a heated sealing ring 5 and two rings 6, 7 resiliently connected to the ring 5 and clamping between them a disc of glass cloth 8. The sealing ring operates through the cloth and after sealing, the glass cloth remains in contact with the bag end while the sealing ring makes its initial upward movement, allowing time for cooling, after which the bag is released. The former is faced with a layer 9 of heat resisting rubber. Specifications 655,646 and 680,351 are referred to.
