STRAIGHTENING ROLLER FOR A ROLLER STRAIGHTENING MACHINE
The subject-matter of the invention is straightening roller for a roller straightening machine intended specifically for straightening railway or tramway rails, characterised in that the working surface of straightening roller is concave over its entire length, while the level of concavity is variable from the extreme points described by radii, which are also the maximum width of the working surface of the straightening roller, up to the centre of the straightening roller's axis of symmetry, where lines inclined towards each other at an obtuse angle between 178° and 179.5° converge and are smoothly joined by a radius - in this area the roller reaches its maximum difference in diameter at the extreme, most convex points and at the straightening roller's axis of symmetry.
