摘要

Improvements in bracing and rubber roller applied in set of drafting system of roving frames, filatu00f3rio and MVs and their processes to obtain improved roller bracing and, more particularly, the Manch u00f5 es (1a) and (1b) are made in a composiu00e7u00e3 The particular layers of nitrile rubber and.At least one of them presents the external surface with roughness (R1), the rollers (2), in turn, present their external surfaces with roughness (R2) constituting, together with the Manch u00f5 es (1a) / (1b), a set of torsion applied in the drafting system of machinery filatu00f3rio roving frames. And MVs or equivalent which enhances considerably the twisting of cotton yarn (FA).Synthetic fibers or mixtures, as well as to improve the production of bars of wires twisted, since it reduces in approximately 600% of production time of a bar of 1 meter.
