Device for the formation of tubular overwrappings in heat-sealable material |
摘要 |
A method of fashioning tubular overwrappings with a heat-sealable material, and a device in which single commodities are directed in succession together with respective sheets of heat-sealable material into a set of pockets spaced apart at a constant pitch around the periphery of an indexing wheel rotated through steps of length equal to a submultiple of the pitch of the peripheral pockets. The pockets currently occupied pause after each step in alignment with a relative set of heat-seal stations and are accompanied through the first step, approaching the first heat-seal station, by a moving folder positioned so as to flatten a first longitudinal flap of the relative sheet against the flank of the commodity; a second flap is flattened similarly over the first flap by a fixed folder whereupon the two flaps are held fast in overlap contact, ready for heat-sealing.
