  • Patent number: 5358187
    Abstract: The present invention relates to the production of shredded paper products such as bedding materials composed of paper bits. Scrap newspapers in tabloid format, or standard straight broadsheet format are cut into a multiplicity of bits, the dimensions predictably and consistantly controlled to insure the paper bit production of substantially uniform and optimally acceptable sizes (length and width) most suitable for the type of end product use intended. This permits the selective production of shredded paper products customized to meet a particular end use, for example bedding material particularly suited for large animal bedding or bedding materials more suitable for small animals such as poultry and/or agricultural mulches.
