Abstract
A system is disclosed for applying plastic labels on cylindrical can bodies which includes moving the cans end-to-end in a continuous series through a forming horn over which a strip of heat-shrinkable sheet plastic is drawn to form the plastic strip into an envelope around the cans with the opposite edges of the strip adjacently disposed longitudinally of the cans, welding the opposite edges of the plastic strip to form a tube around the series of cans, heating the plastic tube to shrink it against the cans, severing the plastic tube between cans to separate them into individually wrapped cans, and further shrinking at least the ends of the plastic tube into snug engagement against the ends of the side wall of each can.
