Abstract

In the procedure for ensuring a precisely positioned introduction of a substitute yarn in a knitting machine by means of a substitute yarn (15) which is attached by a knotter (13) to a running yarn (12), the machine is halted at the desired position for the change of yarn before or after formation of the connecting knot (16) and afterwards the length of yarn located between the knotter (13) and the yarn working position is drawn out past the connecting knot (16) and taken up to one side and the machine is only started up again when the yarn feeder (11) is feeding the substitute yarn.
