Resin impregnation of fiber structures

An assembly for impregnating a continuous length of glass fibers with a polymeric resin, which comprises;

• a base member;
• a convex surface mounted on the base member and having a first contact point;
• a non-convex, surface positioned apart from and in association with the convex surface, said non-convex surface having a second contact point;
• said first and second contact points being on a path line along which the continuous length is free to travel;
• said path line extending both before and after each of the first and the second contact points;
• said path line changing direction toward the center of the arc of the convex surface at the first contact point;
• said path line changing direction away from the center of the second contact point;
• means for tracting the continuous length under tension along the extended path line, whereby the glass fibers are spread apart as the length changes direction at the first contact point and whereby the spread glass fibers are reconsolidated as the length changes direction at the second contact point;
• and
• means for applying the polymeric resin or a polymeric resin forming composition to the spread glass fibers.
