  • Bag making, filling, and packaging method and apparatus
    Patent number: 4965985
    Abstract: A method and apparatus for sealing and closing an end of a sleeve, more particularly an apparatus and method for bag making, filling, and packaging for intermittently delivering a packaging film of a predetermined length, while forming the film into a tubular shape by a bag making cylindrical body; filling the tubular packaging film with a material to be packaged; and clamping the tubular film by closing a pair of opposed sealing devices to heat seal the tubular film. Apparatus is provided for cooling the heat sealed end of the tubular film by a device which is independent of the sealing device. The heat sealed end of the tubular sleeve is positioned and directly engaged by the cooling members which serves to shorten the cooling time, yet provides an improved seal with an improved appearance.
