Abstract
The present invention is directed to a heat-sealing apparatus of a flow wrapper machine which facilitates efficient, reliable and versatile operation. Notably, the apparatus includes multiple ring gears driven by multiple servo motors in a desirably compact configuration, with the arrangement including quickly removable heat-sealing die heads for efficient operation and service. The improved drive mechanism facilitates more accurate heat-sealing head placement, smoother operation, controlled stops, independent temperature control, and continuous running through die jams. Also included is a four-bar link on the heat-sealing head for opening and closing the heat-sealing dies.
