<p>The invention provides an apparatus and method for shrinking portions of a shinkable film beneath leading and trailing transverse end seams (L, R) of a film wrapped product (P). First and second controllable sources (40, 40') of heated fluid are connected to first and second nozzles (32, 32') positioned beneath a conveyor (20) on which the film wrapped product (P) is conveyed. The nozzles (32, 32') are arranged to travel back and forth below the conveyor (20) and their travel is timed such that the heated fluid from the first nozzle (32) heats only the leading seam (L) and heated fluid from the second nozzle (32') heats only the trailing seam (R).</p> |
