Abstract
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.
Claims5
An apparatus for drying sizing compositions disposed onto a fan of fibers attenuated from molten glass streams emerging from a heated bushing prior to the fibers being gathered into a strand and wound to form a package, said apparatus comprising:
- (a) an enclosure through which said fibers pass, comprised of front, back and side wall portions, disposed below said bushing and spaced sufficiently therefrom for heated air around the bushing to be drawn into said enclosure and pass therethrough with said fibers;
- (b) a size applicator mounted adjacent said back wall portion for applying a size composition to the fan of fibers passing through said enclosure;
- (c) a vent opening in said back wall portion above said size applicator for permitting some of said heated air to exit said enclosure;
- (d) a divider disposed in said enclosure below said size applicator to form a first and second longitudinal chamber in said enclosure, wherein said fibers pass through said first chamber;
- and
- (e) a damper pivotally attached to said divider at its end adjacent said size applicator for controlling the relative amounts of heated air passing through said first and second chambers.
