Abstract:
A method for producing a fiber composite containing fibers that constitute at least an essential component of the composite, the fibers having lengths between 20 and 150 mm and being delivered substantially above the height of a material column to a first discharge device through which the fibers are pulled out of the material column and then to a second discharge device which, for the production of a nonwoven fabric with the fibers, directly cooperates with the first discharge device for loosening, clearing and accelerating fibers pulled out of the first discharge device by imparting to the fibers a substantially horizontal acceleration, resulting in ejection of the fibers along parabolic trajectories with an adjustable ejection range established by adjusting operating parameters of the second discharge device, to thereby place and distribute the fibers on a forming belt.
