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.

Abstract: A knitting machine, in particular a flat-bed knitting machine with a plurality of needle beds in each of which longitudinally extending needle tricks are formed in which a knitting needle moves longitudinally. The knitting needles comprise two parts, with one part including a needle head and the other part including a needle butt. The needle head defines a stitch forming part and the needle butt defines a movement-initiating part. A coupling device is provided for each needle to couple the two parts together. A coupling operating device is provided on the cam box carriage for operating the coupling devices in such a manner that the stitch forming part which has knitted is separated from the movement-initiating part until such time as the needle is again selected.

Abstract: A flat-bed knitting machine with a plurality of needle beds in each of which an intermediate plate is situated which is displaceable between four operating positions to thereby control the movement of an associated needle. Also located in each needle bed are pairs of selector plates and associated with each needle bed is an electro-magnetic selecting device which controls the location of the selector plates as a function of the knitting pattern relative to a cam track assembly and the intermediate plate associated with the selector plates.
