Abstract: Individual differently colored or colorable feed filament ends are withdrawn from respective creel-mounted packages and passed through a separation guide. The separation guide serves to "normalize" the filament end-to-end positions and tensions. That is, the separation guide will cause the individual feed ends to be in specific predetermined positions relative to the other feed ends regardless of the position of the package on the creel. In addition, the separation guide will effectively cause a short length of each feed end to be parallel to, and separated by a substantially uniform distance from, corresponding lengths of the other feed ends. This parallel alignment of individual end lengths and the substantially uniform filament end-to-end positioning thereby imparts substantially uniform tensions on the feed ends while substantially maintaining their respective positions in the combined yarn product relative to one another.
