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.

This invention relates to apparatus for receiving and mounting or supporting strand material packages formed by winding strand materials such as textile strands about hollow elongate cores. The apparatus has a central shaft, a rear support mounted on the shaft for engaging one end of a package core and a plurality of fingers for engaging the inside diameter of the core. The rear support and fingers together support a package, while accommodating cores of varying types and sizes. Operation of the rear support and fingers is coordinated by a linkage and a latch which interconnect those elements and the shaft.

This invention relates to apparatus for receiving and mounting or supporting strand material packages formed by winding strand materials such as textile strands about hollow elongate cores. The apparatus has a central shaft and a plurality of sets of finger members and connecting link members mounted for movement relative to the shaft. Each set makes up, together with the shaft, a five bar linkage in which the connecting link forms an engaging means which moves into engagement with the inside surface of an elongate hollow package core as the strand material package wound about the core is mounted for use.
