摘要

Perfeccionamientos in circular machines of means and similars, that essentially comprise an electronic and electromechanical equipment apt to replace the programming with mechanical chain in machines, that include a cylinder of the needles, a drum of the cams of programming and controls to modify the speed of the cylinder between a slow regime and at least a faster regime characterized by the fact of understanding: - a counter of the turns of the cylinder of the needles combined with means of resetting the same, - a programmer group that receives the pulses of said turn counter and which is programmed by means of switchable contacts; - a rotating member integral with the drum of the program and a fixed member, cooperating with each other through controlled contacts by sectors developed according to angular extensions corresponding to the discrete advances of the drum to determine signals according to the instantaneous position of the drum and the duration of the desired successive movements of the latter, on corresponding output lines - a set of matching circuits, fed by the signals of the programmer group and by the signals of the output lines derived from the contacts controlled by the sectors, said matching circuits determining an output, a signal after a number of turns programmed for each determined stopping position of the drum of the cams, in order to control the advance with movement of the cylinder, or through a stepper motor.
