ABSTRACT:
An annular knitting machine comprises a thread exchange device, at least knot unit, means forming a thread processing point, a thread storage device located between the knot unit and the thread processing point, and a control device provided with a microprocessor and a knot data storage for the thread exchange device, the thread exchange device having a sensor which supplies pulses dependent upon a movement of a machine part, the control device also having a microprocessor and a knot data storage and formed so that a length of a thread which is guided through the thread storage device between each knot unit and the thread processing point associated with the latter is maintained at a constant value fixed in the storage of the control device, the sensor supplying movement dependent pulses and being formed as a displacement sensor which is independent of a needle pitch of a needle plate and provides a fixed pulse number per a displacement length unit.
