Abstract:
In a sheet skewing and sheet forward feeding system for inducing skew rotation of a sheet while also feeding the sheet forwardly in a sheet path with first and second laterally spaced positively driven sheet feeding nips, wherein said sheet skewing system selectably provides a difference in said driving of said first and second positively driven sheet feeding nips for said inducing of said rotation of a sheet, the improvement comprising:a differential drive system for said inducing of said skew rotation of the sheet; said differential drive system operatively connecting between said first and second laterally spaced sheet feeding nips; a differential drive motor controlling said differential drive system; and a single forward drive motor operatively connected to positively drive both of said first and second laterally spaced positively driven sheet feeding nips to feed the sheet forwardly in the sheet path by said single forward drive motor being operatively connected to at least one of said first and second laterally spaced positively driven sheet feeding nips through said differential drive system, said differential drive motor being of substantially lower power than said forward drive motor, wherein said differential drive system comprises a laterally movable variable angle mechanical interconnection between said first and second laterally spaced positively driven sheet feeding nips.
