ABSTRACT OF THE DISCLOSURE Yarn feeding device for feeding thread F to needles A of a machine for knitting stockings and similar products operating with a needle cylinder 51 in a continuous one-way motion and with an additional thread guide 98 which cyclically moves beyond the needles in an arc of needles intended to form, without applying tensions to the yarn, chains of loops in the heel of the stocking by placing the thread in front of the needles when they are lifted. Several additional sinkers 59 are positioned above the traditional sinkers 55, and a cam 61 operates the additional sink- ers 59. The cam 61 is in turn operated by two sector gears 63-65, with an interposed idle pinion 67 and with the intervention of rods 73-77 which, by interfering with corresponding pegs 71-75 in sector gears 63-65, stop either one of them to stop cam 61 or to move beyond it. In this manner, the yarn F supplied by the thread guide 98 to the needles A to form the heel is of greater length than that of the arc of the corresponding needles and equal to the length of the loops that the needles must form in each chain.
