  • Patent number: 5538193
    Abstract: A waste paper processing system includes an upper shredding portion and a lower compressing portion. The shredding portion includes to horizontally parallel shafts mounting thereon a plurality of circular blades. The shafts are rotated to spin outwardly of a space between the shafts from a paper feeding direction. Presser arms are provided for retaining paper from above during shredding and stopper arms and a filter portion are provided below the blades to assure the paper is shredded sufficiently. After shredding the paper falls into a hopper and is introduced via a rotor to the compression portion. In the compression portion a screw is rotated for urging the shredded paper into a compression tube the tube as a narrower portion at the lower end for assuring sufficient compression of the shredded paper. In addition, water is added to the shredded paper in the upper side of the compression tube for binding the shredded paper together as pulp.
