Zuführeinrichtung für Stangenmaterial.

摘要

An apparatus comprising a plurality of support members (6) mounted on a rail (5) and movable longitudinally of the rail, a housing (7) mounted on each of the support members (6) and rotatable about a support shaft (22) perpendicular to the length of the rail, and a contact ring (8) mounted on the housing and rotatable about an axis perpendicular to the support shaft (22). An elongated material is inserted through the contact rings (8) and rotated about its longitudinal axis as positioned longitudinally of the rail (5). The angle of inclination of the rotational axis of the material (31) relative to the axis of rotation of each contact ring (8) is variable by rotating the housing (7) about the support shaft (22). Lengths of elongated material of varying diameters are supportable each at its outer periphery by the outer periphery of each contact ring (8) at its axial one end and the other end thereof, with the center axis of the material positioned at a constant level, while the material is prevented from deflective revolution during its rotation. The elongated material supported by the contact rings (8) is fed longitudinally thereof by a feed mechanism.
