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.
