The conical end of an adjustable pin 28, which is adjustable with the aid of a two-armed lever, is arranged in an arm of an angle lever 29, which is mounted in the tiltable yarn guide support ring and is seated on the lever arm 27. This is that one arm of this lever pivots the axis of the support on a pin 30 on the support 1 for the tiltable thread guide support ring so that the circular path of the intersects, and that at this point with this lever 30 pin 28 approximately in the longitudinal axis xx of the support arm one of a cam track of the main control trunnion 3 runs. In the other arm of the angle lever mel controlled angle lever cooperates. 29 one end of a pull rod 31 is attached,

Claim: _the auxiliary control drums are immovable on the cam-thread changing device on a circular knitting plate or the base plate of the machine, especially on a single-cylinder machine, and control the individual thread guides with the aid of multi-system circular knitting machines to manufacture 5 intermediate levers on which the thread guides are positioned of stockings and the like, which come with a main closing of the tiltable frame to rest on the control drum and a tiltable thread guide. The rotation of all auxiliary support ring is provided, on which at least two control drums are arranged by the impulse of the main control thread guide consoles, of which the drum, even when the thread guide support ring is raised, each has an auxiliary control drum for controlling more than one thread guide The auxiliary control drums on the thread guide cam disks are made up of several, the number of which is attached to the supporting ring so that they correspond to the thread guide intermediate levers and form an immovable whole by means of a ratchet and thread guide, rotating wheel and an associated pawl with the on the thread guide acting spring tension bar is characterized in that 15 is caught by the individual consoles.
