Abstract
Control arrangement for trimmings machines, characterized in that the control drum, which assembles the endless chains of command, composed of the bolsters that determine the drive of the thread guide mechanism, describes two turns for each turn made by the motor shaft of the machine, which drives the drum itself through a multiplier transmission, and so that every two contiguous masons of said chain correspond to one pass of the machine, which maltons have their active outer surface according to slopes smoothed for the purpose of to avoid rebounding of the rollers of said system of thread guide mechanism and to achieve a perfect and constant contact, all this in such a way that the cycle corresponding to the set of passes, formed by two half-passages, is carried out with greater speed than in the conventional machines in which each turn of the drum corresponds to one turn of the motor shaft of the machine.
