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.

Abstract: An article feeding and stacking mechanism for receiving a series of articles from a conveyor and then collating the articles for subsequent cartoning or other disposition. A first indexing or collating wheel lifts the articles from the delivery end of the conveyor and stacks or deposits one or more of the articles on an intermediate support. The articles are then lifted by a second indexing or collating wheel and deposited or stacked in predetermined arrangement on a table for subsequent handling. A pair of control guide wheels are positioned above the collating wheels for restraining or limiting unwanted movement of the articles as they are being handled by the collating wheels. The collating wheels have cut-out or recessed portions at that portion of their support surfaces which would normally engage the edge of the articles, whereby the edges of the articles are not damaged by excessive pressure against the collating wheel support surfaces.
