ABSTRACT:
An apparatus for monitoring the output of a fiber cutter arranged to cut long fiber roving strands into short clippings and to feed the clippings into a slurry-containing mixer, the monitoring apparatus having a plurality of rotatably mounted assemblies each comprising a rotating shaft and a plurality of arms mounted thereon. During normal operation the fiber clippings fall through the moving arms and into an apparatus wherein the fibers are mixed into a slurry, such as a calcined gypsum slurry. Malfunction of the cutting apparatus resulting in the discharge of long fiber strands causes entanglement of the fiber strands with the moving arms, thereby causing rotation of the assemblies to discontinue and actuating an alarm and automatic switches, thereby rendering the entire apparatus inoperative and preventing serious entanglement of the mixing and conveying apparatus which could result in long shut-down periods.
