Abstract: 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 mounted on the housing and rotatable about an axis perpendicular to the support shaft 22. An elongated material 31 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 31 supported by the contact rings 8 is fed longitudinally thereof by a feed mechanism 60.

Abstract: A device for preventing deflection of an elongated workpiece rotating about its longitudinal axis is provided with a contact ring (9) that is rotatably mounted about a support shaft (12) perpendicular to the axis of rotation of the contact ring (9). The angle of inclination of the rotational axis of the contact ring (9) is variable relative to the rotational axis of the elongated workpiece (M) inserted throught the ring (9), by rotating the housing (6) about the support shaft (12). The periphery of the workpiece (M) is supported by the inner periphery of the contact ring (9) at two points, i.e., at axial ends of the contact ring. Thus, elongated workpieces of different diameters can be supported by varying the inclination angle of the axis of the contact ring (9) relative to the workpiece (M).
