Abstract
In a guiding device for aligning sheets of paper (13) being stacked in a stacking tray (11) to which the sheets (13) are fed by means of a feeding mechanism (3, 5), deflectable fenders (25 and 26) are provided which are suspended from a mounting element (27) located above the path of the sheets and which extend into the path of each sheet (13), and are contacted and deflected by such sheet. The deflected fenders (25, 26) exert pressure on the contacting surface of the sheet so that the sheet when released by the feeding mechanism (3, 5) enters the stacking tray (11) from above in a controlled manner. At least one (26) of the fenders (25, 26) takes the form of a loop consisting of a flexible web (28) whose two ends are united and suspended from the mounting element (27). As suspended, the flexible loop makes and maintains large area contact with the sheet until stacked resulting in sheets aligned laterally with respect to one another in the stack.
