1. Arrangement for driving a warp beam from a main shaft of a machine via a stepless adjustable drive having a displaceable coupling element for controlling step-up in said stepless adjustable drive, comprising:

  • a setting means for displacing the coupling element in a direction for maintaining a predetermined thread provision rate, the setting means comprising;

    (a) a setting member having a control input and adapted to adjust said coupling element, said setting member being operable to adjust said coupling element in response to signals applied to said control input, and (b) a computing means including;

    (i) an input arrangement for receiving data signifying a prescribed thread provision rate as well as predetermined operating parameters of the machine, the stepless adjustable drive and the beam, which include a winding variable related to actual wind diameter, and (ii) a calculating segment for calculating the desired position of the coupling element from values received by said input arrangement to produce a signal output signifying an appropriate position signal for the setting member, said computing means being coupled to said setting member to apply said signal output to said control input.
