ABSTRACT:
A washer cutting machine is disclosed wherein a sleeve of an elastomeric material suitable for use as a washer is placed on a mandrel and rotated. A predetermined length of the sleeve extends beyond the end of the mandrel, and a knife-edge moves in a radial direction to cut a ring from the end of the sleeve of a width such that it may be suitable for use as a washer. The machine is programmed so that the steps of loading the sleeve on the mandrel, cutting a washer from the sleeve, advancing the sleeve the width of a washer to be cut at the completion of each cutting operation, and stopping operation of the machine after the last washer has been cut therefrom, are all carried out automatically.
