Abstract:
1. A system for making agglomerated fiber strand segment reinforcing products comprising one or more fiberizers for converting molten material to a plurality of fibers, one or more applicators for applying an aqueous chemical sizing to the fibers, one or more guides for gathering the plurality of fibers into one or more strands, a chopper for separating the wet strands into segments, and an agglomerator for combining two or more of said segments into agglomerates and a dryer for drying said agglomerates, the improvement comprising that the agglomerator comprises a generally horizontal, non-rotating wave chamber having an elongated, curved, vibrating working surface for contact with the wet chopped strand segments, a working surface that is concave in cross section on a plane perpendicular with the length of the wave chamber.
