ABSTRACT:
A device for disentangling and spreading short steel fibers used for the reinforcement or crack prevention of concrete or mortar employed for civil engineering works, building constructions or the like. The device comprises a hopper for storing short steel fibers which has a bottom opening which is connected to a nozzle. A horizontal disc rotated by a motor is mounted at the intersection of the bottom of the hopper and the nozzle with the plane of the disc parallel with the general orientation of the nozzle, the disc being formed with a plurality of plate shaped members ranged radially on its upper surface forming an impeller. Projecting from the upper surface of the disc on the axis thereof is a central boss having a plurality of vanes radially mounted thereon in such a manner that they are alternately at different heights. The boss also has pendulum-like agitating arms pivotally mounted at the top thereof.
