Abstract
An apparatus for producing glass fibers is disclosed. The glass filaments are passed across a gathering shoe which may reciprocate in a path such that, when extended, the gathering shoe positions the filaments such that they are out of contact with the application surface of an applicator, which is located between the bushing through which the filaments are attenuated and the gathering shoe so that the filaments are not coated with a binder and/or size from the application surface. The gathering shoe is extended when waste strand is being attenuated, such that the waste strand is not coated with the binder and/or size.
