Patent ID: 7059226

Claim:
An apparatus for forming a hand operated sheet turning device comprising: a stack of sheets of flexible material having a void or notch shape extending inwardly from the edge of each sheet, the void or notch shapes alternating in position with each successive sheet in the stack, comprising: (a) a feeder mechanism for moving sheet material in a feed path, the feeder mechanism comprising: i. first and second paper trays at opposite sides of the feed path, the first paper tray being adapted for receiving the sheet material in the form of stacked sheets, the second paper tray being adapted for sequentially receiving sheets from the feed path; and ii. means synchronized with the notch die mechanism for sequentially advancing a top sheet from the first paper tray into the feed path; (b) a notch die mechanism comprising a die cutter, a die anvil, and means for periodically advancing the die cutter into engagement with the die anvil from opposite sides of the feed path; and (c) index means for registering a leading edge of the sheet material at alternating offset distances ahead of the notch die mechanism prior to successive operations of the notch die mechanism, the index means comprising a stop mechanism coupled to the notch die mechanism for periodically blocking leading edges of alternating sheets at different distances beyond the die cutter and die anvil of the notch die mechanism; whereby successive sheets are formed with alternating alignment of the voids or notches therein for facilitating sequential page turning by alternating the placement of a user's finger and/or thumb on the void or notch of each successive sheet.
