ABSTRACT:
A feed channel for elongated workpieces including a plurality of adjustable workpiece receiving openings. Each opening is formed by a plurality of profiled segments including a fixed segment and at least one movable segment. The movable segments are movable to expose the openings for lateral introduction thereinto of an elongated workpiece. The movable segments are then moved to reduce the size of the openings and engage the workpiece for at least partially straightening same. The movable segments are then moved to increase the size of the openings for providing longitudinal and rotational movement of the workpiece relative to the openings. Workpieces are smoothly carried into the feed channel instead of being rolled or dropped thereinto. The fixed segments are positioned and profiled for locating the longitudinal axes of various diameter workpieces in the same plane.
