In the knitting machine in which each feed (I,II) has two selection points (44,52) for a three way selection of the needles, and in which the spacing of the selection points may depart by a distance (x.t) from an exact multiple of the needle gauge (t), the selection points are controlled by respective timing signals with an appropriate phase lag. The signals may be obtained from respective timing signal generators (56,60) and are fed with control signals from a control device (53) through respective gates (54,55) to the selection points. The knitting machine has at least one knitting tool carrier in which knitting tools are displaceably mounted with a needle distance (t), with a knitting cam assembly (12) assigned to the carrier for guiding the knitting tools (9). The carrier and cam assembly are movable relative to one another, the cam assembly containing a number of systems (I,II) lying one behind the other in the direction of movement (v). The systems have respective selection points with one electrically controllable selection member (44,52) respectively. A timing signal generator produces timing signals in temporal intervals corresponding to the distance (t). A program controller (53) coupled with the timing signal generator emits electronic control signals for the controllable selection members. Both the spacings between the first and the spacings between the second selection points are identical to one another and have a value (s) which corresponds to an integer multiple of the distance (t), in that the spacings between the first and second points are all identical in all of the systems (I,II) and are greater or smaller by a fraction x or y of the distance t than corresponds to an integer multiple of the distance t, where x is larger than or equal to 0, and y is less than or equal to 1. The timing signal generator is set to produce first and second timing signal sequence containing timing signals which have temporal intervals corresponding to the distance t but which are offset relative to one another temporally by a value corresponding to the fraction x.t or y.t. The first timing signal sequence is assigned to the selection member (44) of the first selection point and the other timing signal sequence is assigned to the selection member (52) of the second selection point.
