Abstract: An automatic sheet jogging and stapling machine is disclosed and includes a downwardly, sidewardly inclined platform for receiving sheets of paper, and a side wall and bottom release gate that extend upwardly from the platform to define a sheet receiving corner. Longitudinally and laterally movable jogging fingers are provided to align the sheet edges against the release gate and side wall and a stapling head is mounted spaced above the sheet receiving platform to staple the sheets together. The release gate is opened to gravitationally eject the stapled paper. A cam operated control sequentially actuates the longitudinally and laterally movable jogging fingers, the stapling head, and the release gate.
