ABSTRACT:
A filamentary tow package is prepared in which the tow is in layers of substantially vertical folds and has adjacent layers impacted with one another. Sections of the tow are alternately twisted to give helix angles varying from greater than 45.degree. in an S direction to greater than 45.degree. in a Z direction. The helix angle of the tow is increased by impacting it into layers of tow previously laid down. Removal of tow from the package is improved.
