Abstract: Disclosed is an apparatus and method for false twisting a monofilament or multifilament yarn. False twisting means are provided to impart twist to the yarn and the twisting means employs a fluid medium both to twist the yarn and control the tension of the yarn being twisted. Additionally, there may be separate means provided to supplement or more accurately control the twist being imparted to the yarn.

Abstract: An apparatus is disclosed for taking up one or more strands. The strands are received by a capstan from a strand processing source of supply at a relatively high tension. Each strand is fed by the capstan to a take-up apparatus at a relatively low tension so long as at least a particular minimum force is applied by the take-up apparatus for winding to the particular strand. When this minimum force is no longer applied to the strand the capstan ceases to feed the strand. The capstan is continuously driven at a constant speed. Preferably, a skewed idler roll is provided in association with the capstan for maintaining the strand wraps about the capstan and roll separate and distinct from each other. The tension at which the strands are fed to the winder may be varied by means of adjustable bails for varying the length of contact of the strands with the capstan. One of these bails is provided to obtain substantially equal tension of the strands fed to the take-up apparatus upon start-up of the apparatus, and another of the bails provides for a desired tension of the strands fed to the take-up apparatus during subsequent taking up of the strands. When winding of any strand stops, for example, when a wound package is full and the strand is cut, or the strand breaks between the capstan and the take-up apparatus the minimum force required for feeding of the strand to the take-up apparatus terminates so that feeding of the strand is automatically stopped while the capstan continues to be rotated.

Abstract: Winding apparatus for concurrently winding a plurality of strands of yarn into separate take-up packages while continually monitoring the tension in each strand and compensating for variations therein to wind the take-up packages to be of substantially equal diameter is disclosed. The apparatus includes a plurality of spaced winding units each adapted to wind an individual strand of yarn into a take-up package. All of the winding units are driven with one common variably controlled motor. Further, each separate winding unit includes a rotatable package support and a separate package pressure roll for engagement with the periphery of an associated take-up package. Means are provided for applying a separate biasing force to each package support to control the pressure under which each said package support engages its associated pressure roll.

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.
