Abstract
The invention provides an apparatus and method for shrinking portions of a shrinkable film beneath leading and trailing transverse end seams of a film wrapped product. First and second controllable sources of heated fluid are connected to first and second nozzles positioned beneath a conveyor on which the film wrapped product is conveyed. The nozzles are arranged to travel back and forth below the conveyor and their travel is timed such that the heated fluid from the first nozzle heats only the leading seam and the heated fluid from the second nozzle heats only the trailing seam.
