LEVER SYSTEM FOR COMPENSATING THE FORCES INDUCED BY A THREAD GUIDE SHAFT IN RAPID ALTERNATING MOVEMENT

摘要

The present invention relates to a lever system for compensating the forces induced by a thread guide shaft in rapid alternating movement along a thread winding frame and the said compensating lever system comprises the following elements interacting in a co-ordinated way: - L-shaped lever elements; - cams with identical profiles, each cam being associated with one of the said L-shaped levers; - elements which are elastic in tension and in compression, intervening simultaneously in each stage of accumulation and return of kinetic energy; - mechanical rolling members fixed on a slider, which is made integral with the thread guide shaft; the said mechanical members are combined in alternating movement with the profiles of the cams to impart angular movements to the L-shaped levers.
