Title (EN) SUPPLY PACKAGE FOR WET-IMPREGNATED MULTIFILAMENT ROVING
(FR) DISTRIBUTEUR DE MECHES A PLUSIEURS FILAMENTS IMPREGNEES DE LIQUIDE
Abstract:
(EN) 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 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 In this manner the wet-impregnated roving can be stored wet in the way wound cylinder and easily withdrawn therefrom when needed.
(FR) Distributeur de meches a plusieurs filaments impregnees de liquide dans lequel la meche est impregnee d"un liquide polymerisable possedant un coefficient d"arrachage inferieur a 6 environ (mesure a l"aide d"un appareil Thwing-Albert), la quantite de ce liquide etant suffisante pour remplir les espaces entre les filaments de la meche, mais n"excedant pas la quantite correspondante a un rapport de 3:2 entre les volumes respectifs de liquide et de fibre. La meche impregnee est bobinee autour d"un cylindre de facon telle que l"angle forme entre deux meches situees dans des couches adjacentes soit d"au moins 10 environ, ceci afin de menager un volume libre permettant le stockage entre les meches ainsi orientees, volume qui peut recevoir tout liquide susceptible de fuir. De cette facon la meche impregnee de liquide peut etre stockee sur le cylindre et prelevee de celui-ci a la demande.
