ABSTRACT:
A mechanical device for controlling the tension in a traveling textile yarn includes a base, a flutter member pivotably mounted on the base and a cylindrical post eccentrically mounted rotatably on the base adjacent the post, the flutter member and post being independently biased toward one another and yieldably movable independently away from and toward one another. A yarn monitoring arm is integral with the post and extends outwardly therefrom for engagement with a traveling yarn passing between the post and the flutter member. Tension increases and decreases in the yarn act on the monitoring arm to effect movement of the post in its rotational directions away from and toward the flutter member to increase and decrease the frictional drag and thereby offset the tension change. The flutter member yields to yarn thickness fluctuations and is adapted for flutter-like pivotal movement in response to yarn ballooning and untwisting actions to dampen same while maintaining the frictional drag on the yarn. The device is effective for maintaining a very low amount of tension in a traveling yarn while still providing an effective stop motion.
