Abstract: A moving strand is provided and a size is applied to the strand. A collet is rotated to wind the strand and build a package. The strand is reciprocated with a strand reciprocator to lay the strand at a wind angle on the package surface as the package rotates. A rotatable collet receives the strand to build a package. A strand reciprocator is mounted to guide the strand from edge to edge of the package and to lay the strand in a helical pattern on the package surface as the package rotates. The collet and the cam for the strand reciprocator are driven by motors. A collet inverter drive and a cam inverter drive control the rotational speed of the collet and cam, respectively. A controller is operatively connected to control the collet and cam inverter drives. A memory device such as a computer provides information to the controller of the waywind and wind angle as a function of package buildup time.

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.

Abstract: A guide eye for use with a traverse mechanism of a strand package winder is positioned with respect to the surface of the package during the package build process so that the guide eye contacts the package surface in the larger diameter, end regions of the package. This positioning provides a minimal free length between the point at which the strands leaves the guide and the point at which the strand contacts the package surface, giving better control over the placement of the strand onto the package surface, particularly in the end portions of the package. Further, the guide eye is pressed against the package surface, slightly compressing the surface and pressing a portion of the preceding stand courses against the package. This pressure helps to fix the strand in the position in which it was laid down to reduce displacement of the strand course during the package build process.
