ABSTRACT:
A continuous cutter ring or hoop having relatively thick, large-angle chisel teeth to bend and break attenuated glass fibers in a glass fiber chopping assembly is disclosed. The continuous cutter is an annular ring or hoop of steel or other hard material which is formed having an outer circumference provided with integral, regularly spaced, raised cutting teeth. The continuous cutter is secured on a suitable cutter wheel which cooperates with a second wheel having an elastomer cot around its circumference with the glass fibers to be severed passing between the continuous cutter and the elastomer cot. The cutter teeth are generally chisel-shaped and sever the glass fiber strand without cutting or destroying the elastomer cot. The integrally formed cutter teeth will not separate from the cutter ring and are not subject to being misaligned.
