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.
