摘要:
The invention relates to a device for stacking flat, flexible objects situated on a narrow edge, successively in a stacking compartment. The aim of the invention is to avoid the rear edges colliding with the front edges of the next objects, even when the objects have different lengths. To this end, a plurality of deviation elements (3, 4) are used, said elements being successively arranged in the direction of each stacking compartment, in order to deviate the rear parts of the objects (2) seen in the displacement direction; the distances between the objects (2), the length thereof and the position thereof at certain points in time are determined; and, based on said values, the deviation elements (3,4) are temporally controlled in such a way that, for both short and long objects (2), the rear parts of the objects (2) are deviated in relation to the rear edge inside a maximum distance.

In an embodiment, a post-processing apparatus (40) includes: a stacking tray (17); an upward and downward driving unit (89); a binding unit (49); and an upward and downward driving control unit (96). The upward and downward driving unit (89) drives the stacking tray (17) in vertical direction. The binding unit (49) performs binding on recording media (S) on the stacking tray (17). The upward and downward driving control unit (96) controls such that: descent of the stacking tray (17) is performed before a leading edge of a first sheet among the recording media (S) on which the binding is to be performed reaches a position on the stacking tray (17); and after the leading edge of the first sheet is positioned on the stacking tray (17), ascent of the stacking tray (17) is performed before a leading edge of a second sheet among the recording media (S) reaches a position on the stacking tray (17).

Das Taschenfalzwerk umfasst wenigstens eine Falztasche (24) mit einer Einlauföffnung (25) und einen Bogenanschlag (26), wobei vor der Einlauföffnung (25) ein erstes Falzwalzenpaar (18, 20) für einen Transport eines Bogens (12) in die Falztasche (24) und ein zweites Falzwalzenpaar (20, 22) für einen Transport und eine Falzung des Bogens (12) nach Auftreffen des Bogens (12) auf den Bogenanschlag (26) angeordnet sind. Um eine Produktionsleistung bei optimaler Falzqualität zu erreichen, ist die Transportgeschwindigkeit der Falzwalzenpaare (18, 20; 20, 22) unabhängig voneinander einstellbar.
摘要:
A method and apparatus are for decelerating a sheet of paper in a paper-cutting system. The sheet of paper is cut (705) using a cutter, and the sheet is then accepted (710) into a take-away nip. The take-away nip is operated (715) at an initial rate in order to move the sheet of paper away from the cutter at an initial speed. The take-away nip is then operated (735) at a rate decreasing to a final rate, in order to decelerate the sheet of paper to a final speed by the time the sheet of paper exits the take-away nip. The take-away nip is subsequently operated at the initial rate again, prior to accepting another sheet of paper at the initial speed.

Stapeltragetisch mit einer Stapeltragplatte (5) zum Tragen eines Bogenstapels (7), die durch einen Antrieb heb- und senkbar antreibbar ist. Der Antrieb ist bei Vorhandensein eines Gegenstands in einem von der Stapeltragplatte (5) durchfahrenen Bereich stillsetzbar. Im umlaufenden Randbereich der Stapeltragplatte (5) sind ein oder mehrere Sensoren angeordnet, durch die das Vorhandensein eines Gegenstandes in dem von der Stapeltragplatte (5) durchfahrenen Überwachungsbereich erfaßbar sowie bei Erfassung eines Gegenstandes in dem Überwachungsbereich von dem Sensor ein Signal erzeugbar und dem Antrieb diesen stillsetzbar zuleitbar ist.
