DEFINITION

Classification: 242/419.1

Slackness sensor:

(under subclass 419) Subject matter wherein the elongated material moves along a desired path subject to a degree of gravitational or similar sag proportional to the stress in the material, and the tension control system includes means to apply a retarding force against the running material in response to a detector actuated in response to deviation of the material from the desired path.
