ABSTRACT:
The invention relates to method and apparatus for producing fibers from heat-softened mineral material, such as glass. More specifically, this invention relates to method of and apparatus for glass fiber production using a bushing of the type having an orifice plate with a plurality of closely-spaced orifices and a flat exterior surface comprising moving a receiving member into spaced-apart relationship immediately below the orifice plate of the bushing, flowing heat-softened glass through the orifice plate to form a body of heat-softened glass between the receiving member and the orifice plate and in contact with the receiving member, and moving the receiving member with the body of glass from the orifice plate at a rate effective to form fibers.
