Abstract
The invention relates to a back-edge stop in the form of a cross-member for sheet stackers of sheet-fed presses having a vertically positionable intermediate stacker which forms a relatively large stack, the cross-member being pivotally connected to the sheet brake by way of a link parallelogram support. A sheet brake has disposed on it fixed sheet stops and at least one further fixed sheet stop having a recess in which a brush is pivotally mounted, the bristles of the brush being inclined forwardly and downwardly and extending into the major surface of the stack a distance substantially equivalent to the difference in sheet size. As the intermediate stacker rises and falls, the brush is pivoted, by way of an inclined cam surface on the cross-member, this surface being connected non-positively to engage an actuating edge of the brush to make a controlled pivoting movement around a horizontal axis extending transversely to the direction of sheet movement.
