ABSTRACT:
In a packaging system, carton sleeves are sealingly closed at their bottoms while received upon respective mandrels, the open-topped cartons are removed from the mandrels and filled, and the filled cartons are sealingly closed at their tops. Between the bottoms being sealingly closed and the cartons being filled, selected cartons are turned through a right-angle about their own axes to bring their top closure sealing sub-panels into a correct orientation for top-sealing. For enabling such turning the mandrels are turnable about their own axes by a cam displaceable between operative and inoperative positions.
