Abstract

Improvements in sewing machines that allow to automatically make stitches forming different motifs, in which at least one of the two elements carrying a needle and tissue conveyor is subject to the action of a command device intended to locate the exact location where the the needle attacks or punctures the tissue, characterized in that this control device comprises a digital progribuidor that supplies electrical signals, a series of contact elements to which said signals are transmitted, a drive device mechanically linked to said element. Carrier needle and transporter of the tissue that moves in one direction and in another, an explorer device that moves at the same time as the said element in front of the said contact elements with each of which is contacted, successively and, finally an electrically operated stop mechanism at the moment in which the referee the scanner is in front of the contact element fed by the distributor, causing the stop of the actuating device and, consequently the stop of the driven element, needle holder and tissue conveyor in a position thus determined by the distributor.
