Abstract

1446573 Let-off take-up motions SULZER BROS Ltd 28 Sept 1973 [29 Sept 1972] 45488/73 Heading D1E The cloth tension is measured and the signal derived therefrom is used to control the warp let-off. A load cell 30 on a breast beam 12 measures the cloth tension and its output signal Xe is fed to a comparator 31 where it is compared with a set tension value Xk. The output signal Xa from the comparator 31 is fed to a controller 32 which adjusts the input to a variable speed motor 24 which drives a friction roller 8 pulling off the warp. The cloth speed, i.e. pick density can also be sensed, as well as the tension, by a sensor 33 which also feeds its signal Z into the controller 32 to adjust let-off.
