Precision winding method and apparatus

摘要

A method and apparatus for step precision winding yarn into a package (P). During winding, the traverse frequency is adjusted so that a first actual winding ratio parallels adjacent a first integer winding ratio. When the rotational velocity of the package decreases sufficiently, the traverse frequency is step increased so that the first actual winding ratio step decreases to the second actual winding ratio adjacent a second integer winding ratio. A ratio between the first actual winding ratio and the first integer winding ratio defines an integer offset ratio and a ratio between the second actual winding ratio and the second integer winding ratio corresponds to the integer offset ratio.
