DEFINITION

Classification: 242/421.5

Slackness sensor:

(under subclass 421) Subject matter wherein the tension regulating system includes a detector responsive to changes in gravitational sag or similar deviation of material from a desired path as the material unwinds from the delivery coil, which detector serves as a material stress information input component.
