ABSTRACT:
An apparatus is provided for creating a heat seal in polymeric film packaging material located between adjacent bundles of one or more workpieces. The apparatus comprises a support frame and a conveyor system associated with the support frame for receiving a plurality of spaced-apart bundles of one or more workpieces and moving the bundles along a first path extending from a first portion of the support frame to a second portion of the support frame. The spaced-apart bundles are at least partially wrapped in polymeric film material as they move along the first path such that sections of the film material extend between adjacent, spaced-apart bundles. The apparatus further includes a heat seal device for effecting a heat seal in the polymeric film material located between the adjacent bundles. The heat seal device includes a carriage, first servo-drive apparatus for effecting movement of the carriage back and forth along a portion of the first path, a first seal bar assembly mounted on the carriage for movement toward and away from the first path, second servo-drive apparatus for effecting movement of the first seal bar assembly toward and away from the first path, and processor apparatus for controlling the operation of the first and second servo-drive apparatuses.
