Abstract
A paper hold-down device for a sheet collecting and stacking apparatus comprising a sheet hold-down arm disposed at the entrance to the apparatus for holding down the trailing edge of the stack at the entrance while the next sheet is fed onto the stack. A cam is fixed to a moving sheet feeding mechanism and acuates the hold-down arm as the feeding mechanism moves into alignment with the entrance to the apparatus. A spring is connected to the arm for returning it to its original position as the sheet feeding mechanism moves away from the entrance thus allowing the sheet that was just fed to join the others in the stack.
