  • Spray coating applicator apparatus and method
    Patent number: 6547883
    Abstract: 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.

  • Methods and apparatus for the cooling of filaments in a filament forming process
    Publication number: 20020129624
    Abstract: Cooling systems and the methods of cooling filaments using the cooling systems are disclosed. One embodiment of the cooling system includes a layer of nozzles that spray air on the filaments above a pre-pad water spray. Alternatively, another cooling system utilizes air-atomizing nozzles to spray a mixture of air and water on the filaments.

  • Nonaqueous sizing for glass and carbon fibers
    Patent number: 6020064
    Abstract: A nonaqueous sizing composition useful for coating glass or carbon fibers. The composition comprises one or more epoxy resins, one or more polymers, a lubricant and one or more silane coupling agents. The sizing composition reduces the volatile organic components associated with chemical treatment of glass and carbon fibers while also eliminating the need to disperse or emulsify the ingredients of the composition.
