ABSTRACT:
While a series of hollow moulded articles interconnected by waste portions are successively moulded by a rotary moulding machine and are continuously conveyed by a pair of conveyors, the waste portions are removed from one end of each of the articles by applying a twisting force to the waste portions by means of cutter means. The waste portions are removed from the other end of each of the articles, and then such ends may be sealed.
