ABSTRACT:
A glass fiber attenuator is disclosed which is used in the fiber forming process. The attenuator is comprised of two rapidly moving endless belts which travel along a predetermined path. The belts have surface portions which engage glass fiber strand and apply attenuating forces to the fibers which are being drawn. The attenuator has a smooth surface bearing means to abruptly change the direction of movement of the belt with respect to the strand traveling along the predetermined path. At least a portion of one of the belts rides over a stationary member having sufficient porosity to pass a fluid therethrough. Adequate pressure of the fluid causes the belt to ride on the fluid along the predetermined path.
