Abstract
A fiberizer is described having a rotor to which plural hammers are mounted for fiberizing a sheet of fibers delivered to the rotor as the rotor is rotated. A feed mechanism utilizing a pair of seal rollers, at least one of which is driven, is configured for effective delivery of both wet or dry sheets to the fiberizer. The hammers are configured to minimize dead spaces within the fiberizer. In addition, air flow is directed through the fiberizer to minimize accumulations of fibers therein. Furthermore, an optional liquid flushing mechanism is provided for periodically cleaning the fiberizer during use.
