Tension control by servo motor in textile application using electronic let off and electronic take up technique

Weaving is the mostly used method of fabric production for the decoration, clothing and home furnishing textile sectors and paper industry. However, in textiles including cloth and produced on weaving machines Irregular of the weft insertion method used. For weaving very high cycle and acceleration rates is required for weaving machines. Furthermore, weaving machines has very large number of non linear motion sequences and timing. As per Mechatronic solution using the combination of servo drives for warp let-off and fabric take-up are used. More recently, non linear motion and weft insertion have also been implemented with electric drives in some instances. That type of let off motion in which the weaver's beam is driven with the help of servo motor, as the beam diameter changes, RPM of the beam are controlled through load cell. Take-up is used to draw the fabric of cloth at regular rate (picks/inch). It is synchronized with let off motion. The speed of take up is less than let off motion due to crimp of warp.
