  • the method according to the invention can be used in particular to join portions of knitting produced by at least two groups of needles located in two sectors of a same bed, constituted for example by the needle cylinder of a cylinder-and-dial machine, which are mutually angularly spaced around the axis of the bed, on the same machine used to produce them.

  • each of which accommodates at least one engagement element which can be constituted by a hook or by a pusher or by a needle, which can move on command along the corresponding radial slot in order to pass from an extracted position, in which it protrudes from the peripheral profile of the dial, to a retracted position, in which it is recessed within the dial in order to avoid interfering with the needles of the needle cylinder.
  • the engagement elements can interact with at least one needle of the needle cylinder in order to engage a loop of knitting or more generally a portion of a row of knitting produced by the needles of the needle cylinder or in order to release a loop of knitting or a portion of a row of knitting engaged previously to a needle of the needle cylinder.
  • the engagement elements can retain the loop of knitting or portion of row engaged previously without interfering with the needles of the needle cylinder.
  • the engagement elements can pick up loops of knitting, in the strict sense of the term, from the needles that have produced them or can retain portions of loop linking yarn during the formation of a row of knitting by the needles of the needle cylinder and then release to the needles of the needle cylinder the loops of knitting previously picked up or the portions of loop linking yarn previously retained.
  • the expression "loop of knitting” is understood hereinafter to designate a portion of a row of knitting which can be constituted by a loop of knitting in the strict sense of the term or by a portion of loop linking yarn.
  • each engagement element is constituted by two or more elements arranged side-by-side, which are generally arranged in a same radial slot of the dial and cooperate with each other and with the needles of the needle cylinder in order to pick up loops of knitting from the needles of the needle cylinder or release to the needles of the needle cylinder loops of knitting previously picked up by other needles of the needle cylinder or retained during the formation of a row of knitting on the part of the needles of the needle cylinder.
