Method and apparatus for regulating the yarn strip width in warping machines

摘要

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.
