Patentansprüche:Patent claims: 1. Vorrichtung zum Vereinzeln von Schriftstücken aus einem Stapel,' bei der ein angetriebenes, mit über die gesamte Länge gleichmäßig ■ verteilten Löchern versehenes endloses Förderband vor einer an eine Vakuumleitung angeschlossenen Saugwanne läuft, dadurch gekennzeichnet, daß eine variable Antriebs-Übersetzung (14) zwischen dem Antrieb (10,11) des Förderbandes (6) und einer Einrichtung (16) zur periodischen Unterdruck-Erzeugung in der Saugwanne (9) angeordnet ist, so daß die Frequenz der Unterdruck-Erzeugung gegenüber der Antriebsgeschwindigkeit des Förderbandes verv änderbar ist. """1. Device for separating documents from a stack, 'in which a driven endless conveyor belt provided with holes evenly distributed over the entire length ■ runs in front of a suction pan connected to a vacuum line, characterized in that a variable drive transmission (14) the conveyor belt (6) and means (16) for periodically vacuum generation in the suction head (9) is arranged between the drive (10,11) so that the frequency of the negative pressure generating respect to the drive speed of the conveyor belt is ver v alterable . """ 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Einrichtung (16) zur periodischen Unterdruck-Erzeugung in der Vakuumleitung (17, 18) als Drehschieber ausgebildet ist.2. Apparatus according to claim 1, characterized in that the device (16) for periodic negative pressure generation in the vacuum line (17, 18) designed as a rotary valve is. 3. Vorrichtung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, daß die variable Antriebs-Übersetzung (14) als Wechselgetriebe ausgebildet ist, dessen Antriebswelle (13) mit dem Antrieb (10,11) des Förderbandes (6) und dessen ä Abtriebswelle (15) mit der Einrichtung (16) zur periodischen Unterdruck-Erzeugung verbunden sind.3. Device according to claims 1 and 2, characterized in that the variable drive transmission (14) is designed as a change gear whose drive shaft (13) with the drive (10, 11) of the conveyor belt (6) and its ä output shaft ( 15) are connected to the device (16) for periodic negative pressure generation.
