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 by a lap sealer or side sealer. 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 second station comprises a cross head sealer unit which includes a skip seal mechanism thereon for overriding mechanical synchronization of the cross head sealer to the remainder of the machine through a predetermined number of sealings, allowing for packages of greater length to be accommodated, the skip seal mechanism further including a shock absorbing subassembly for smoothing action of the cross head sealer unit, increasing functional longevity of the cross head sealer unit.
