Abstract

A device for the determination of the position of leading or trailing draw-down elements which can be shifted to operated in opposite directions in flat-bed knitting machines has a single step motor for shifting the draw-down elements, a position sensor and a switching element movable in relation to each other and cooperating with each other, the switching element indicating a basic position of the two draw-down elements. So that in such a device besides the basis position of the two draw-down elements the shifted position, i.e. which of the two draw-down elements is in the draw-down position, can be machine-internally determined, a second switching element is provided, which is operationally connected with the position sensor, the second switching element and the position sensor being movable in relation to each other and the second switching element being synchronously movable with the first switching element. Furthermore, the second switching element is associated with one of the two draw-down elements for the determination of the switched position of the two draw-down elements.
