5 Claims. (Cl. 118-234)
As a speci?c example, the apparatus disclosed herein
is provided for impregnating a glass ?ber roving with a
controlled amount of uncured liquid resin whereby a
length of the impregnated material may be used to form
an article built up in a desired manner with the impreg
nated rovings which are then heat treated to form the ?nal
article. The article thus has a controlled ratio of glass
