It is provided with cam sets in association with intermediate jacks having a long upper butt and a short lower butt and said intermediate jacks are adapted to assume three different positions, one in which both butts emerge, corresponding to the jersey knitting stage, another in which only part of the long butt emerges corresponding to the tucking stage and a third position in which no butt emerges, corresponding to the welting stage.

Abstract: Procedure for knitting hose with a toe and heel in a circular knitting machine having more than one feed and two needle cylinders. All needles are brought to an upper path during knitting of the toe and heel with alternating motion, and at every oscillation of the cylinder those needles alone which have been selected to knit the course relative to the oscillation are brought back to work from the upper path towards a lower working path. The selection of needles is brought about by cooperation between fixed radial cams situated so as to correspond with the main feed and appropriate selection actuators. The selection for jacquard designs takes place upwardly from the lower path to the upper path by cooperation between appropriate selection actuators and movable radial cams located so as to correspond with each feed. The upper path serves to exclude the needles of the lower cylinder from work and also to protect the upper cylinder needles, the lower path being the path for jacquard designs.

Abstract: For needle selection in a circular knitting machine, a device is disclosed which comprises a plurality of superimposed selecting levers, individually pivoted to a common structure and selectively movable between a position where they do not interfere with the pattern jack butts and a position where they interfere therewith, to urge them toward the needle cylinder. The selective movement is accomplished by means of electromagnets, one for each selecting lever, which are energized in accordance with the machine knitting program and move intermediate, preferably rod-like, drive elements the axial displacement whereof results in a pivotal movement of the respective selecting levers between the cited positions. The engagement of the intermediate elements with the selecting levers is accomplished through geometrical coupling. A minimal force is sufficient for the actuation, so that the size of the electromagnets can be minimized, while a prompt response is ensured.
