STRAIGHTENER

WIPO Patent Application WO/2006/003728

A1

A straightener in which the shape of guide bar facings is simplified and the guide bar facings are effectively used. In the straightener, a clearance (S) opening in a direction orthogonal to a line connecting the axes of straightening rolls (12) and (14) to each other in a plane orthogonal to a carrying route is formed between the vertically opposed straightening rolls (12) and (14). The pair of guide bar facings (30) and (30) guiding a work material (W) are formed in generally rectangular flat plate shapes, and disposed on the inlet side and the outlet side for the work material (W) of both straightening rolls (12) and (14). Also, the guide bar facings (30) are disposed aslant relative to a carrying face (PL) along the opening direction of the clearance (S) so as not to be interfered with both straightening rolls (12) and (14). The guide faces (32) of the guide bar facings (30) are formed such that the guide bar facings (30) can be linearly moved forward and backward along the opening direction of the clearance (S) relative to the carrying route in the state of facing the carrying route parallel with each other through the clearance (S).
