Abstract

An apparatus for shrinking a wrapping about goods carried on a pallet has a transport device defining a support surface for displacing the palletized goods in a transport direction and including an upstream conveyor, a station conveyor spaced downstream by an upstream gap from the upstream conveyor, and a downstream conveyor spaced downstream by a downstream gap from the station conveyor. A heat ring has upstream and downstream portions and side portions extending in the direction therebetween. This ring is displaceable between a lower position with the upstream and downstream portions in the gaps below the surface and the side portions flanking the station conveyor and an upper position above the surface. An actuator displaces the ring between its upper and lower positions. Thus the ring need merely be moved upward once the pallet is positioned on the station conveyor within it to preshrink the wrap and drive out the air in it, then is moved down once to its starting position to fully shrink the wrap in place.
