Abstract

937,011. Packaging. DU PONT OF CANADA Ltd. June 28, 1961 [July 2, 1960], No. 23321/61. Class 94(1). A synthetic plastic bag is sealed by a thermoplastic tape 2 formed into a U-shaped crosssection enfolding the mouth of the bag and heat sealed to both outside surfaces, The apparatus for sealing the bag comprises two knurled wheels 10 and 11 mounted on each side of chains 14 and 15 and a unit 29 which folds the tape 31 about the bag mouth. The bag is forwarded by the chains 14 and 15 and the tape is drawn from a roll 26 to the unit 29 and over the mouth of the bag. The wheels 10 and 11 press the tape against the bag mouth and forward them together to the heat sealers 25. The tape is automatically cut off by the knife assembly 30.
