Abstract
A supply package for wet-impregnated multifilament roving is provided in which the multifilament roving is impregnated with a curable liquid having a tack less than about 6 (measured on a Thwing-Albert inkometer) in an amount at least sufficient to fill the spaces between the filaments in the roving, but not in excess of about a 3:2 ratio of curable liquid to fiber, by volume. This impregnated roving is way wound onto a cylinder to provide a crossing angle between the rovings in adjacent layers of at least about 10.degree. to provide free volume storage capacity between the angled rovings which accepts any liquid which may run off. In this manner the wet-impregnated roving can be stored wet in the way wound cylinder and easily withdrawn therefrom when needed.
