ABSTRACT:
A continuous motion in line sealer assembly includes a sealer star wheel which is coordinated with a plurality of rotatable and receiprocable vacuum heads. Each vacuum head obtains a flexible foil sealing disk from a point of supply and positions the disk atop a container. The vacuum head and container then pass through an induction tunnel to activate a heatable adhesive. A pair of stationary cam plates control both the reciprocal motion of the vacuum head as well as providing it with a dwell time which momentarily interrupts its continuous motion to facilitate sealing disk acquisition.
