ABSTRACT:
Device to compensate the elongation of two or more wire rods or round bars on machines fed with two metallic wire rods or round bars of iron or alloys thereof of a type for building work, the machines being, for instance, bending/shaping machines, the device comprising a pair of opposed rolls (12), namely an upper roll (12a) and a lower roll (12b) respectively, the rolls (12) defining between them respective inner (17a) and outer (17b) passes (17), with which the wire rods passing through cooperate, at least one (12a) of those rolls (12) being able to move substantially parallel to itself on a plane containing the axes of the rolls (12), the rolls (12a-12b) having respective shafts (15a-15b) each of which is fitted to a relative support (13), namely to respective upper (13a) and lower (13b) supports, the other roll (12b) being able to move in a controlled rocking manner on the plane containing the axes of the rolls (12) and being adjusted by a bottom positioning screw and a return spring (22).
