ABSTRACT:
A feed arrangement for a rotating bar includes a rotary drive carrying a series of axially spaced clamping devices comprising collets through which the bar passes. The clamping devices are axially reciprocated in phased sequence and the collet of each device closes upon the bar while the device is moving forwards. The sequence is so controlled that at all times the bar is clamped by the collet of at least one forwardly moving device and is thereby continuously fed forwards while being rotated by the active clamping device.
