Abstract
An apparatus for controlling a selectable knitting machine mechanism such as needle selection mechanism or a yarn feed changeover mechanism in a knitting machine having a rotating knitting machine component such as a needle cylinder, a cam box, or a dial is disclosed. The apparatus includes at least one sensor for detecting the rotational speed of the knitting machine component and generating a periodic signal therefrom. A control mechanism cooperates with the sensor and generates a control signal to the selectable knitting machine mechanism responsive to a predetermined trigger point of the periodic signal. The control mechanism includes a mechanism for delaying the predetermined trigger point when the rotational speed of the knitting machine component is relatively slow and for advancing the predetermined trigger point when the rotational speed of the knitting machine is relatively fast. The control mechanism includes a phase-control, frequency/voltage converter.
