Title: Selection device for oscillating jacks in a circular knitting machine

Abstract: A selection device for oscillating jacks in a circular knitting machine comprising selection levers pivotal between an active position in which the jacks are radially thrust by a thrust profile of the levers, and an inactive position. The levers are moved into one of these positions by engagement of a control profile of the levers by the butts and are held in this position by a permanent magnet. The flux of the magnet can be neutralized temporarily by program-controlled windings to permit release of a selected lever whereby the lever is moved into its other position by means of a bias.
