<p>An applicator for the deposition of size and other coating compositions onto the surfaces of reinforcing fibers (2), such as glass. The device may be used to apply aqueous or non aqueous size to continuously formed fiber materials in a high speed forming process. The applicator may include an atomizing spray pre applicator (3) in combination with a slide die applicator (6). The atomizing spray pre applicator can be connected to a vacuum source (5), which increases contact of the spray with the fibers, and thereby improves coating coverage. The slide die applicator may include a slide die configuration that reduces leakage of the liquid coating. The process of using the invention can provide a more uniform thin film coating, higher coating efficiency, and better coating coverage than size applicators otherwise known in the art.</p> |
