Abstract
On the warping machine (12) the width (11) of the yarn strip (10) is continuously monitored by means of a line camera (25). The measured strip width is compared in a processor (32) to a stored reference value, with deviations forming a control signal for activating a control motor (35) at the warping reed (9). That ensures continuous strip width regulation, at full winding speed.
