ABSTRACT:
In the process for the control of the warp speed during direct warping, the winding diameter is determined by a contactless measurement. The actual thread speed is determined from the winding diameter and the current warp beam rate of rotation. A direct warping machine for carrying out this process has a transducer for measuring the winding diameter. This transducer is located proximate to but not in contact with the circumference of the winding for measuring the winding diameter. Also included is an arrangement for the determination of the rate of rotation of the warp beam. Also, a computer can calculate the thread speed from the above outputs that correspond to winding diameter and rate of rotation.
