Abstract

Automatic mechanism to increase the number of needles in straight knitting machines, characterized by the fact that the number of needles in play during knitting operations is increased by the intervention of tilting fingers that, varying their position along the corresponding knitting according to known means, they determine the setting in working position of the precise needles in each case, whose fingers are mounted in a sliding manner on respective bars parallel to the bores and oscillating, each of which is divided transversely into two halves, being activated Each half by means of a lever and a tie that, in turn, those of the same end, are subject to thrust or traction by an electromagnet excited at will to be acted on a control button governed by the operator of the machine, being an electromagnet is disposed at each end of the machine, in two lateral frames thereof and in a symmetrical position with respect to both needles, to activate each of them the needles arranged in the corresponding halves of the fonturas, taking place the aforementioned activation of the needles by the direct or indirect push that the two in question exert against the rear end thereof, the electrical connection of the push button with the electromagnets is made through two longitudinal half conductor bars, related thereto, along which a contact related to the push button slides.
