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 app…
