Abstract

Improvements in the draw frames of high draw for the production of discontinuous textile fibers, of the type comprising three groups of rotating cylinders and horizontal axis, respectively feeding, control and drawing, and where each group comprises lower cylinders and upper cylinders cooperating with one another along a generatrix, said cylinders being obtained on at least partially transverse trees, in order to vary the distance between the various groups of cylinders, characterized by the fact that the trees relative to the cylinders lower parts of each group of cylinders are supported in the extremities, in a rotating manner, by two support bodies mounted movably on a base in a direction perpendicular to said trees and that, for each group of cylinders, the first of the two support bodies it is linked superiorly, through means with hinge of perpendicular axis the trees have a rotating arm that supports the upper cylinders, while the second of the two support bodies has blocking means able to cooperate with the rotating arm to block the upper cylinders in contact with the lower cylinders, the pairs of support bodies are displaceable relative to the various groups of cylinders independently of one another.
