Attorney, Agent or FirmAbstractApparatus for inverting and stacking sheets successively conveyed along a path. Each sheet is sensed and actuates an inverting means which causes an element to engage and slow the leading edge of the sheet at a discharge region and deflect it from the path to a stacking platform. The trailing portion of the sheet continues to be moved by conveying means at approximately its original velocity and moves past the leading edge so that the sheet is rolled over and deposited in an inverted position on the stacking support or preceding sheet. The stacking support is sloped upward at its outer edge to facilitate removal of a portion of the stacked sheets while continuing the stacking operation. The conveying means extend over the stacking support to insure that the shorter sheets as well as the longer ones are properly deposited on the stack. By using a plurality of sheet engaging elements on the inverting means, sheets having a wide range of sizes can be deposited on the stack. | |
