Abstract: A rotary closing machine for closing bottles with mouth lips by closures such as closure caps, corks and the like, which includes a supply container for receiving and supplying closures of the just mentioned type, and also includes a conveying device for feeding the content of the supply container to closing units having closing elements which are adapted to be lifted and lowered in the process of closing the bottles by the closure caps or the like closures. For pressing the closures, e.g. closure caps, against the respective bottle mouths and permanently deforming the closures on the bottle mouth, each closing unit has a deforming member and a holding down member extending through the deforming member; these two members are movable relative to each other. The device furthermore comprises a rotatable element associated with the conveying device for transferring the closures from the conveying device to a holding device at the lower end of the holding down member.

Abstract: A conveyor mechanism including two belts carries two types of interfitting molded articles such as cups and lids from a molding machine to an assembly station, maintaining a constant orientation between them. The assembly station comprises a pair of synchronized and overlapping star wheels, counterrotated by a Geneva drive, which remove the molded articles from the conveyor belts, bring them into vertical alignment, and come to a momentary stop in this position in which a plunger synchronized with the Geneva motion of the star wheels joins the two parts together and pushes them into an overlying stacker tube, whereupon the star wheels resume their motion. Several stacker tubes, linked by an endless transport chain, are capable of receiving a limited number of pairs of molded articles, their drive mechanism being so coupled with the star-wheel drive as to advance the chain to bring a loaded stacker tube to an unloading station whenever a preceding tube in the array has been filled.
