(57) In a straightener machine for bars and the like, such as flat and section bars of
various description, the straightening operation is performed by pressure members
(24) entrained by two endless flat link chains (14,15) juxtaposed with respect to
a bar path (3a) defined through the machine (1).
The pressure members (24) of the working runs of said chains (14,15) are shifted operatively
toward the bar path (3a) by adjustable guide cams (41-46); thus, the deformations
nor. mally brought about by traditional straighteners of the roller type are prevented
to provide a higher proportion of bars hav- , ing an acceptable degree of straightness.
