ABSTRACT:
A method of dispensing a reinforcement strand includes the steps of chopping the reinforcement strand into discrete reinforcement fibers, directing the discrete reinforcement fibers into a dispensing nozzle so that the discrete reinforcement fibers travel along a path extending generally along a longitudinal axis of the nozzle, introducing a fluid into the nozzle in a circumferential direction with respect to the longitudinal axis, thereby creating a vortex of the fluid surrounding the discrete reinforcement fibers in the nozzle, dispensing the discrete length reinforcement fibers from the nozzle as a flow, and controlling the flow of fibers dispensed from the nozzle by controlling the fluid introduced into the nozzle.
