Abstract
A continuously operating machine is provided for wrapping articles with a heat shrinkable plastic film automatically and sequentially. Articles are continuously, transferred along a horizontal pathway to a plurality of processing stations. At a first station, articles are tubularly overwrapped and sealed along a side edge thereof with excess film material being automatically trimmed away. Next, the articles are separated one from the other at a second station and at a last succeeding station, the resulting wrapped articles are subjected to thermal film shrinking. The side seal and trim apparatus includes a heat seal and trim unit which engages free side edges of the film tube to one another and trims excess away, the unit being sandwiched between drive and alignment members.
