ABSTRACT:
A method and assembly for sealing articles incorporates a continuously moving transfer mechanism which receives the articles from an intermittent feed and feeds them to an intermittent sealing mechanism. The intermittent sealing mechanism uses an elongate sealing member or heater plate which extends over a substantial portion of the sealing mechanism. The sealing member has a plurality of separate heaters functionally associated with the plate to apply heat to the articles at a plurality of stations during dwell times while the articles move through the sealing mechanism. The sealing member or heater plate reciprocates into and out of contact with the articles during the dwell periods by a cam to effect simultaneous sealing action at the plurality of stations.
