Abstract: Winding apparatus, such as a Model 959 take-up machine, manufactured by Leesona Corporation, Warwick, R.I., has a base on which a spindle frame is pivotally mounted for receiving a yarn package and urging the package against a roller bail mounted on the base. As the package increases in diameter during winding, the spindle frame is progressively moved away from the roller bail which continues to engage the face of the package. The package may tend to bounce or otherwise move away from and toward the roller bail for various reasons, such as an eccentricity in the longitudinal face of the package developing during winding or caused by an eccentric package core. A friction type dampener is provided for dampening such movement of the package on and off of the bail. This dampener has a frictional dampening part fixed to the base and movably secured to the spindle frame by a leaf spring having one end fixed to the dampener and the other end secured to the spindle frame to eliminate any play therebetween in the direction of movement of the spindle frame toward and away from the roller bail, while permitting relative movement between the spindle frame and the dampener. Frictional retardation provided by the dampener is adjustable.
