Abstract: A self-supporting package of strand is disclosed. The disclosed method of manufacturing a package of strand is directed to the bulk collection of the strand. The disclosed strand collection system includes an attenuator that attenuates filaments from a bushing. The attenuator includes a pair of belts between which the strand is pinched to pull the filaments from the bushing. The attenuator directs the strand to a deflector assembly that slows down and imparts a degree of movement to the strand. The deflector assembly includes primary and secondary deflector surfaces which the strand engages. After the strand deflects off the secondary deflector surface, it is directed into a container assembly. The attenuator and deflector assembly traverse above the container assembly to deposit the strand. The container assembly is periodically vibrated by a vibrating mechanism as it collects strand. The vibrations settle and shift the strand in the container assembly for better strand distribution.

Abstract: An apparatus for forming multiple packages on a single collet includes a pair of collets that are mounted on a rotatable turret. A moving strand is provided and the collet is rotated to wind the strand and build a first package on one end of the collet. The strand is reciprocated with a strand reciprocator to lay the strand on the package surface as the package rotates. After the first package is built, a strand positioner and a secondary shoe assist in transferring the strand to build a second package on the collet. After the second package is built, the turret is rotated while the cam moves away from the collet and turret. The strand breaks off after a few revolutions of the second collet. Then, the cam moves toward the second collet to begin building a first package on the second collet.

Abstract: A collet is rotated to wind a strand and build a package. The strand is reciprocated with a strand reciprocator having a strand guide to lay the strand in a pattern on the package surface as the package rotates. As the package builds, the diameter of the package increases. A method includes a startup procedure for selecting a desired rotational speed or torque of the collet prior to building the package. As the package builds, the torque on the collet is monitored and kept within upper and lower operating curves to control the package density. The method can also monitor the torque of the cam and/or receder to control the force exerted by the strand guide on the package.
