Abstract

A new system for making agglomerates of chopped glass fiber strand segments is disclosed and claimed. The agglomerates, made by feeding wet chopped fiber strand segments into a wave chamber having a vibrating curved surface that produces a wave-like flow pattern in the segments and agglomerates, have a substantially higher bulk density and greatly improved flow characteristics than conventional chopped strand reinforcements. The wet agglomerates are usually dried in any conventional dryer.
