ABSTRACT:
Apparatus for straightening elongate material, such as wire, has a rotary member which includes an internal passage through which the material is passed. Guide means in the rotary member guide the material through the passage and include deflection means for deflecting, and thus flexing, the material as it passes through the rotary member. The deflection means is so shaped as to cause the path taken by the material to have a first, curved portion which is directed away from the axis followed by a second portion, which is substantially parallel with the axis of rotation or is less tightly curved as the first portion, both portions being spaced from said axis of rotation, and preferably preceding a third curved portion which is substantially the same radius of curvature as the first curved portion and which directs the wire back towards said axis of rotation. This arrangement allows for a greater degree of flexing of the wire for any given extent of radial displacement from the axis of rotation and thus improves the effectiveness of the straightening apparatus. The straightening apparatus can be used in a wire bending machine which incorporates a bending head situated downstream of the straightening apparatus.
