ABSTRACT:
An apparatus for the controlled feeding of concrete strengthening and adhesion material, such as plastic fibers, to a concrete mix. The apparatus includes a set of reciprocating spikes that contract the fibers with a comb-like action that separates the individual fibers and moves them forward to a rotating agitator having a central rotating shaft with spokes extending outwardly to provide a further separation of fibers and a forward movement of the fibers toward a rotating impeller which moves the fibers forward and downward to a duct which exits to a concrete mixing apparatus. The separation of the fibers prior to entry into the concrete mix serves to inhibit or prevent subsequent aggregation or balling of the fibers in the mix.
