ABSTRACT:
An apparatus is disclosed for the attenuation or advancing of strand material, such as glass strands. The apparatus includes a single belt and a plurality of wheels around which the belt is driven and guided. The strand is attenuated as it passes between the belt and one of the wheels. The wheel which, along with the belt, attenuates or advances the strand may have a plurality of pins or bars to form its exterior surface, which surface is then discontinuous. Alternatively, this wheel surface may be continuous. The driving force for the belt comes from another of the wheels, with the driving force being applied to the belt on the opposing surface of the belt from that which contacts the strand.
