66925-400 ABSTRACT Melt Extruded Polymeric Compositions and Processes of Moulding Them Moulded articles such as gaskets for container caps are made from a thermoplastic composition at high speed, for instance above 100 per minute, by continuously cutting a continuous supply of molten thermoplastic composition into molten pieces and trans- ferring the molten pieces to a moulding position at which they are moulded into the gaskets or other desired articles, and the compo- sition includes a melt-release material that continuously replen- ishes a melt-release layer on the surfaces by which the molten composition is cut and transferred to the moulding position.
