Class Information
Number: 242/418.1
Name: Winding, tensioning, or guiding > Tension control or brake > Supply controlled > Feeder associated with coil > Slackness sensor
Description: Subject matter wherein the material is adapted to be advanced along a path by the feeder at a rate to establish a desired level of material tension that is reflected by a degree of gravitational or similar sag of an unsupported portion of the material, and the tension control system includes a detector actuated in response to deviation of the material from an acceptable degree of sag to adjust the rate of advancement by the feeder to thereby reestablish the desired tension.
