Abstract
Apparatus for making a stable block from paper including means for providing a plurality of moist paper fragments, means for roughening the outer surface of a group of the moist paper fragments, and means for compressing the group of paper fragments to form the group of paper fragments into a stable block without the addition of an adhesive.
Claims20
An apparatus for making stable blocks of paper comprising:
- a first conveyor;
- means for supplying paper fragments to said first conveyor;
- said first conveyor moving the paper fragments along a first path;
- a pickup conveyor for removing paper fragments from the first conveyor and moving the paper fragments along a second path which extends upwardly from the first conveyor, said second path forming an obtuse angle with the first path;
- means defining an open zone extending downwardly from the upper end of said pickup conveyor whereby the paper fragments fall from the upper end of the pickup conveyor through said zone;
- means for directing a liquid into said zone beneath the upper end of said pickup conveyor;
- means for transporting the paper fragments from said zone-defining means;
- means downstream of said directing means for compacting the paper fragments;
- and
- means downstream of the compacting means for compressing the compacted paper fragments to form stable blocks of paper.

Apparatus for making stable blocks of paper, comprising:
- means for providing shreds of paper having small fibers;
- means for fluffing the shreds of paper;
- means for moistening the fluffed shreds of paper;
- means for providing an initial compaction of the moistened shreds of paper;
- and
- extruding means operative under heat and pressure on initially compacted shreds of paper to intertwine the fibers and compact the shreds of paper and form the blocks,
- the extruding means including dies provided with die passages for receiving the shreds of paper and at least portions of the surfaces of the die passages being roughened.

Apparatus for making stable blocks of paper, comprising:
- means for providing shreds of paper having small fibers;
- means for moistening the shreds of paper;
- and
- extruding means for applying heat and pressure to the moistened shreds of paper to compress the shreds of paper into blocks, the extruding means including dies having passages with roughened surfaces for intertwining the fibers to facilitate the formation of the blocks and the retention of the blocks in compressed form.
