Abstract: A continuous supply of tubing is fed intermittently into a work station. Partial cuts are made at periodic intervals by a cutoff head that operates in timed relation with tube clamping device. Tube gripping device then pulls on the end portion or segment to position it precisely downstream of and in alignment with the freshly cut tubing end. A double tube end forming device moves in between the downstream end of the tubing and the upstream end of the tube segment. This device has tube end forming heads that include tooling for suitably shaping both these ends simultaneously.

Abstract: A machine for straightening an elongated workpiece has a plurality of coacting tools which include first and second sets of tools arranged in alternate series along a fixed longitudinal axis to engage successive longitudinally spaced portions of a workpiece positioned therebetween with its longitudinal center line generally aligned with a longitudinal axis. A cam operated lever system simultaneously reciprocates the tools of the first and second sets in opposite transverse directions relative to the longitudinal axis and each other to alternately displace portions of the center line of the workpiece to one and the opposite side of the longitudinal axis. A mechanism is provided to vary the magnitude of reciprocating lever movement to vary center line displacement between a position of maximum displacement and a position wherein workpiece portions are substantially longitudinally aligned.

Abstract: A tube cutting machine has a cutting station and an intermittently operable feed means comprising an air cylinder operating a feed clamp assembly. The cylinder and clamp assembly axially advance an elongated section of tubing to present trailing end portions of leading end tube sections at the cutting station. A cutting clamp assembly securely holds the tube rearwardly of each trailing end portion for the cutting operation. A centrally apertured rotary cutting head has three radially movable rotary cutters or rollers which effect a partial cut at each trailing end portion. The cutting head and its operating means include positive mechanical actuating means for the small rotary cutters or rollers and an adjustable means is provided for precisely limiting inward cutter or roller movement in accordance with tube diameter and wall thickness.
