A needle selection device for circular knitting machines for women's stockings, including a pusher jacks associated with each of a plurality of needles of a needle cylinder, each pusher jack having two heels including an upper heel interacting, in a selection position, with a lower cam and a lower heel interacting, in a selection position, with a pressure cam, acting in a radial direction with respect to the cylinder, and with a raising cam. A horizontal collar is provided formed of non-magnetic material anchored around the needle, the collar defining a plurality of radial grooves. A plurality of horizontal elastic selector jacks are positioned in one of the radial grooves. A permanently magnetized ring is fastened below the collar, facing the selector jacks, spaced a distance from the selector jacks to retain said selector jacks only when said selector jacks are inclined downwardly. A permanent magnet is supported by a fixed structure with respect to the cylinder in a region of each pressure cam for removing the selector jack from the horizontal rest position for urging the selector jack to the permanently magnetized ring, to the position inclined downwardly. A vertical tappet is provided positioned between the permanent magnet and an inclined surface of the raising cam, and positioned under the selector jack for selective detachment of the selector jack from contact with the permanently magnetized ring, whereby the position of the selector jack maintains or modifies a position of the corresponding pusher jack upon passage of the pusher jack over the pressure cam for determining non-operation or operation of a corresponding needle.

The tubular knit product with a pocket and a method for forming the pocket using reciprocating motion in tubular knit hosiery manufacturing. The method uses a circular knitting machine fed by a plurality of yarn feeds which all participate in the formation of the pocket by a reciprocating motion. During the reciprocating motion, part rows of stitches from yarns of the various feeds are formed in a sequence on a course. For the next preceding opposite course, the part rows of stitches from the yarns of the various feeds are formed in a sequence which is opposite. For each subsequent course, the sequence is opposite to the preceding course, and the course direction is opposite (reversed). On each successive reversed course, the yarns of the various feeds form rows which progressively decrease in a first part of the construction of the pocket and progressively increase in a second part of the construction of the pocket. The points of reversal of the rows formed by the various yarns on one side of the pocket appear in a sequence opposite to that in which they appear on an opposite side of the pocket.

The articles are formed on individual arcs of needles (13, 15) facing each other on the two bars of the cylinder (11) and of the plate (10), the articles having rows formed partly by the needles of one bar and partly by the needles of the other bar, and having two successive yarn feeds (344, 345); means for guiding and switching (458, 459) the position of the two yarns supply them to the needles at two angles and exchange their positions at each reversal of the entrainment thereof by the selective entraining means comprising pairs of hooks (342, 343; 349, 350) carried by two counter-rotating apparatuses (26; 32).

The thread feeding apparatus for double needle bed knitting machine to form tubular fabric comprises at least two thread-guides for the same number of thread feed systems for the same fabric, said thread-guides are displaced the one relative to the other upon the passage between one needle bed and the other and upon the reversal of the knitting direction, in order to maintain the same precedence order of the thread-guides in respect to the instantaneous direction of motion. In order to ensure the unwinding of the yarns with no crossing thereof, said yarns are unwound from bobbins of yarn which are co-axially disposed in a row, holes or other equivalent thread guiding means being provided, which guiding means rotate preferably with a continuous motion.

Several pairs of tubular articles are formed on two circular fixed fronts of needles using threads reciprocating transfer mechanism. The articles are alternatively formed by the two fronts by using sets of needles whose number may also vary. By using adjacent sets of needles, the two tubular, leg-shaped articles of each pair are successively formed to make up a body, that is, the panties portion for a pantyhose garment.
