An apparatus for applying a liquid composition to one or more fibers of a fan of fibers provides a housing defining an elongated passageway therethrough such that the fan of fibers travels along a path through the passageway. The apparatus further provides a plurality of centrifugal spray heads including at least a first centrifugal spray head mounted in the housing and supplied with the liquid composition under pressure for directing the liquid composition onto one or more fibers of the fan of fibers passing a first location of the path. The plurality of centrifugal spray heads further includes at least a second centrifugal spray head mounted in the housing and being supplied with the liquid composition under pressure to direct the liquid composition onto one or more fibers of the fan of fibers passing a second location of the path.

Spray coating applicator apparatus and method

An applicator for the deposition of size and other coating compositions onto the surfaces of reinforcing fibers, 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 in combination with a slide-die applicator. The atomizing spray pre-applicator can be connected to a vacuum source, 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.

Applicator for coating fibrous materials

A sizing applicator is provided for applying a coating of sizing composition to glass fibers. The sizing applicator includes a housing and a roll applicator which is rotatably coupled to the housing. The housing has a supply port adapted to receive sizing composition from a sizing supply source, an exit slot and a passageway extending from the supply port to the exit slot. The passageway receives sizing composition from the supply port and delivers the sizing composition to the exit slot such that the sizing composition exits the housing and is received on an outer surface of the roll applicator. The roll applicator is spaced from the housing such that the housing does not substantially contact the sizing composition once it is received on the roll applicator.

Apparatus for applying a generally uniform sizing composition to glass

A method and apparatus are provided for producing uniformly sized glass fibers. A heated bushing supplies streams of molten glass to be drawn into continuous fibers, and a drawing device attenuates the streams into fibers. A sizing applicator has a coating element engaging the drawn fibers, which applies a coating of sizing composition to the fibers. A shoe spaced from the applicator engages the fibers and causes the fibers to sweep back and forth across the element.

Method and apparatus for applying a sizing composition to glass fibers

Energy efficient apparatus for forming migration free glass fiber packages composed of fibers bearing substantially uniform coatings of size composition. Heated air from around the fiber forming bushing is drawn into a chamber through which the glass fibers pass to cause the water or solvent in the applied size to be evaporated. The flow of heated air through the chamber is regulated so as to obtain substantially uniform size application to the fibers.
