Negative Let-Off Mechanism

Experiment Name: Study on Negative Let-Off Mechanism.

Introduction:
Let-off is to supply warp thread in the weaving zone at a predetermined rate. Negative let-off is a mechanism for controlling the rotation of the beam on a weaving, warp knitting or other fabric forming machine where the beam is pulled round by the warp against a breaking force applied to the beam.
