ABSTRACT:
This invention comprises apparatus and methods for folding and crimping shredded strips of sheet material into preselected lengths of interlocking, decorative material and/or bulk packaging material. The apparatus generally includes an attachment for a commercial paper shredding device which shreds sheet material therein. The apparatus comprises a movable barrier against which the shredded strips of sheet material are impelled upon being expelled from cutting blades of the shredding device. The movable barrier causes the strips to become controllably jammed within a confined area between the barrier and the cutting blades. Further insertion of additional strips into the confined area causes the strips to become compacted, folded, and crimped against a remaining dam of jammed sheet material located within the confined area. This causes the strips to fold and press against themselves, and form lengths of thin sheet material having an accordion-shaped configuration. Cutting blade components may be provided to further cut the strips into preselected lengths.
