Abstract: A wear adjustable shredder having spaced apart, parallel rotating shafts, series of interleaved and overlapping cutter disks carried on the shafts, and an adjustable cutter disk assembly carried endmost on one of the shafts, the adjustable cutter disk assembly having an inner adjusting ring and an outer cutting ring with the cutting ring threaded on the adjusting ring. The cutting ring may be rotated with respect to the adjusting ring such that the ring moves axially toward or away from the cutter disks to adjust the spacing of the cutter disks.

Abstract: A paper metering device is disclosed which is adapted for handling a flow of bulky and unmanageable paper such as newspapers or computer printouts and metering the paper into a manageable flow for delivery to further processing. The flow of paper is carried upward on a feed conveyor. A converging conveyor is disposed along a substantial portion of the feed conveyor at the discharge end. The upper layers of the paper contact the underside of the converging conveyor which advances the paper out the discharge end. The converging conveyor is disclosed as a plurality of disks on rotating shafts or as an endless belt. Means for sensing the height of the flow of paper under the converging conveyor is provided, such that the feed conveyor is stopped until the height of the flow is reduced. Also provided is means for jogging the feed conveyor if the feed conveyor is not restarted after a predetermined period of time.
