ABSTRACT:
A method and apparatus is disclosed for the in-line pre-impregnation of glass or synthetic fibers with a non-aqueous chemical treatment. The apparatus includes a first applicator for applying a curable, non-aqueous chemical treatment agent and a second applicator for applying a curing agent for the chemical treatment agent. The fibers are passed over the first and second applicators which are arranged either in parallel or in series, and are then joined by a gathering device to initiate curing of the chemical treatment agent on the fibers. In an alternative embodiment, the apparatus includes a spray gun in which a mixture of the non-aqueous chemical treatment agent and curing agent are sprayed onto an applicator roll in contact with the fibers.
