ABSTRACT OF THE DISCLOSURE A supply package for wet-impregnated multi- filament 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° 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 In this manner the wet- impregnated roving can be stored wet in the way wound cylinder and easily withdrawn therefrom when needed.
