ABSTRACT:
A device for sealing wrapping material on pieces of candy or similar products, in what is known as the "soap" style of wrapping, and for exiting the products, in their sealed wraps, from the wrapping machine. Each wrapped product is first received in a correspondingly dimensioned pocket of a horizontal conveyor disk, which intermittently conveys the product along a sequence of plates, comprising a presser plate, a first heat-welding plate, and a first cooling plate. The presser plate eliminates bulges of the sides of the product, created during the wrapping. It presses other sides of the product, with folded tabs of the wrap thereon, into the pocket. The heat-welding plate then seals portions of the wrap on a then exposed side of the product. After the cooling and during one of the steps in the intermittent travel of the disk, the product enters a similarly dimensioned but differently arranged pocket of a vertical, intermittently movable conveyor disk, which by the next following steps in its intermittent travel conveys the product along a second set of heat welding and consecutive cooling plates, for sealing the folded tabs of the wrap on then exposed sides of the product. The vertical disk finally brings the product in its sealed wrap to an exiting station.
