ABSTRACT:
An improvement in the production of chopped fibers is provided. Long fibers, commmonly in the form of roving, are fed through a chopper assembly comprising a cutter wheel having a plurality of outwardly-extending blades and a back-up roll having a soft cylindrical surface which the blade edges contact with the fibers therebetween. The chopped fibers then are directed downwardly through a discharge chute to a distribution chute below the chopper where they are directed by air to a point of application, e.g. being mixed with resin and applied to a surface of a mold or mandrel. The chopper fibers have had a tendency to agglomerate into hunks or balls below the chopper assembly and such tendency has heretofore been substantially reduced by the use of static bars located below the chopper assembly. An air system is now provided for directing air downwardly past the chopper assembly to convey the chopper fibers therefrom through the discharge duct and the distribution chute. This air flow substantially prevents agglomeration of the fibers and eliminates the need for the static bars heretofore employed.
