A collet (22) is rotated to wind a strand (14) and build a package. The strand is reciprocated with a strand reciprocator (30) having a strand guide (38) to lay the strand in a pattern on the package surface (20) 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 (96, 98) to control the package density.

Why it's free to use
- Filed March 16, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 16, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
