TUBE CUTTING APPARATUS Abstract of the Disclosure A tube cutting apparatus designed for use in severing predetermined lengths of stock from a continuously moving workpiece includes a reciprocating carriage assembly on which is supported a driving motor directly connected to a continuously rotating cutting assembly. The workpiece is fed to the cutting assembly through an axially extending bore in the motor shaft. In one embodiment, the driving motor is fitted with end plates having integrally formed guides thereon. The cutting assembly includes a plurality of pneumatically actuated pistons each of which has either a roller or a cutting wheel secured thereto, all of which cooperate to sever the predetermined lengths of stock from the workpiece. The pistons and associated cutting wheels and rollers are designed to be actuated into engagement in response to application of fluid pressure thereto and are retracted by operation of centrifugal force resulting from continuous rotation of the cutting assembly. In one embodiment, the cutting assembly is specifically designed for quick and easy removal and reinstallation so as to enable rapid changes between different size workpieces. An optional stop assembly is also provided which includes a ram assembly operative to assist in completing the severing operation and in ejecting the workpiece from the tube cutting apparatus upon completion of the cutting operation so as to reduce the possibility of jamming.
