Abstract
To determine thread winding parameters for reducing the rate at which deviations from a cylindrical shape are formed in thread packages being wound, thread packages are successively formed by laying thread upon a driven rotary chuck while pressing a driven rotating contact roller against the package in a manner causing a circumferential force to be transmitted therebetween. Each package is inspected for deviations from a cylindrical shape. The generation of slippage is promoted at an interface between the contact roller and package. The amount of promoted slippage is changed between the forming of successive packages to change the rate at which the deformations are formed.
