Abstract
Percent take-up feed of a yarn, which is taken up onto a pirn by rotary surface contact with a take-up roller via delivery rollers, is time-functionally and continuously changed by a speed converter which is inserted into a rotation transmission mechanism between both rollers and whose speed conversion ratio is adjusted by a pilot shaft in accordance with a programme which is designed on the basis of the take-up feed characteristic curve in order to obtain a yarn of uniform stretch property, the characteristic curve being in practice approximated by a combination of three or fewer straight lines.
