A device to prevent the rotation of longitudinal advancing rods or wire, particularly for straightening or eventual bending machines, comprising:

on a first working plane (A) a first group of advancing rod deviating means realizing a pathway deviation angle, preferably comprised between 10° and 90°, by two inclined rod roller straightening guide means realizing each one, said continuous arm levers guide means (c,c'), placed along the triangle sides between the deviating angles, of the respective rod angled deviation, being donwards from the second inclined roller straightening guide means (c'), a reangleing means (e) placed, to realign the advancing rod on the advancing working pathway line parallel to said plane;
on a second working plane (B) parallel to said advancing and working pathway line, orthogonal and downwards placed from the first (A): a further first incliend rod roller straightening guide means (c") is placed, being downwards this one a rod roller reagling means (e') on the advancing working line parallel to said plane provided.
