Abstract
A paired-roll straightening machine designed for straightening rolled shapes, round and shaped tubes and rolled section stock comprises a number of stationarily installed stands mounting pairs of driving shafts which form passes by their rolls, corresponding to the cross section of an article being straightened. The rolls form pairs with some of the pairs intended for propelling the article and the remaining pairs for bending the article. Each roll of the pairs intended for bending the article is provided with an individual drive for rocking in a given plane. In addition, each bending pair of rolls is provided with an additional drive for combine rocking of both rolls of the pair in a plane perpendicular to the given one. This allows for multiplanar elastoplastic bending of the article to be performed in the course of straightening.
