System for packaging a succession of objects in a foil

摘要

A packaging system has a guide at a sealing station which forms the leading end of an elongated wrapping foil into a tube having a closed downstream end. A conveyor feeds a succession of objects spaced apart in a transport direction by gaps into the tube at this station. A pair of grippers can close on the leading edge of the object to be wrapped in the tube and pull it through the sealing station so as to position its rear end immediately downstream of a pair of vertically displaceable welding tools that are closed on the tube in back of the object to weld together the sides of the tube and form a new closed end on the tube.
