Abstract
The invention is an apparatus and method for accurately applying a cord to a rotatable mandrel while manufacturing cord reinforced articles. The apparatus includes a rotating build mandrel, a cord supply, and a feed capstan for assisting in feeding cord from the cord supply to the mandrel along a defined cord path. At least two drums of differing diameters are located in the cord path. Encoders are connected to each drum for measuring at least the angular movement of the drum. Using the angular movement of the drums, the effective pitch line differential of the cord is determined.
