US 4,143,534 A · Workpiece feed channel

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.

Dependent claims

A feed channel for elongated workpieces comprising:

a plurality of longitudinally spaced adjustable workpiece receiving openings, each said opening being formed by a fixed segment and at least one movable segment which is movable between open and closed positions for respectively exposing said openings to lateral introduction of workpieces thereinto and closing said openings, opposed straightening rolls which are opposed in a predetermined direction lying in a plane, and said fixed segment being profiled and positioned for supporting workpieces of varying diameters with the longitudinal axes of such workpieces lying substantially in said plane even though such axes are spaced varying distances from the bottom of said fixed segment, and positioned to define a side segment and is generally V-shaped, said plane being generally horizontal and said straightening rolls being horizontally opposed.
