PCT No. PCT/EP88/00384 Sec. 371 Date Jan. 4, 1990 Sec. 102(e) Date Jan. 4, 1990 PCT Filed May 5, 1988 PCT Pub. No. WO88/08893 PCT Pub. Date Nov. 17, 1988.In a method for positively feeding an elastic yarn to the knitting system of a circular knitting machine having a yarn feeder apparatus controlled by an electronic control unit, the apparatus of a take-out signal (A) initiates the count of a preselected number of position signals (p) before generating a stop signal (S), or otherwise the take-out signal (A) is disregarded for a preselected space of time at the end of which the stop signal (S) is generated, the number of position signals (p) or the space of time, respectively, being selected in accordance with the yarn quality and/or the distance between the yarn feeder apparatus and the knitting system. In this manner the yarn feeding operation is continued for relaxing the elastic yarn. The electronic control unit (3) of the yarn feeder apparatus (2) in the circular knitting machine (1) includes a delay circuit (19) for controlling the generation of the stop signal (S).
