ABSTRACT:
In a packaging machine of the kind in which a tubular film is wrapped around the articles to be packaged as they are advanced over a conveyor belt and the film is heat-welded and severed, the improvement consisting in that the welding and the counter-welding rods are vertically reciprocated between respective inactive positions and an approached position whereat both rods cooperate to effect the welding and the film-severing. The height adjustment to allow for different heights of the articles to be packaged is thus greatly facilitated and the film pull reduced.
