ABSTRACT:
A banderoling machine joins film webs from a roll to form a film curtain. Film is placed around material to be banderoled to form a loop and the loop is tightened to clamp at least one of the film webs, and is heat-sealed and separated from the remainder of the film. The web need not be positioned exactly and there is no film waste by providing, a film changing unit where both the working film web and the supply film web are guided through a film sealing unit having at least one separating heat-sealing device to produce a pinch-separating seam between the old working film web and the supply film web and between the excess supply film web and the remainder of the old working film web.
