Hopper blender system and method for coating fibers |
摘要 |
A system for coating discontinuous fibers with a liquid coating material uses a hopper/blender which entrains the fiber particles in a toroidal mass of moving fibers. The hopper/blender has an inverted conical section with an agitator assembly rotated therein. The agitator assembly has a base disc with tubular blades projecting outwardly therefrom into the conical section. Aft swept lifter blades relative to the direction of rotation are mounted to the agitator disc. A method of applying a liquid coating material to discontinuous fibers is also disclosed.
