Abstract

Zur Erhöhung der Haltekraft eines Sauggreifers ist in des­ sen Greiferfuß (18) etwa im Zentrum mindestens ein Stift (17) angeordnet. Dadurch kann eine schlupffreie Übernahme des in einem Druckwerk 1 bedruckten Bogens von dem Druckzylin­ der (5) an den Überführungszylinder (9) erfolgen. Bei der Übernahme des hinteren Bereiches (15) des Bogens (12) durch die Sauggreifer können die Stifte (17) in den Bogen (12) eindringen und diesen gegebenenfalls durchbohren. Im letzte­ ren Falle ist es zweckmäßig, in Abhängigkeit von der Länge des Bogens jeweils elastische Streifen (19) auf dem Druck­ zylinder (5) anzuordnen. To increase the holding force of a suction pad is in the sen gripper foot (18) approximately in the center at least one pin (17) arranged. This allows a slip-free takeover of the in a printing unit 1 printed sheet from the printing cylinder the (5) to the transfer cylinder (9). In the Takeover of the rear area (15) of the arch (12) by means of the suction pads, the pins (17) can be inserted into the bow (12) penetrate and pierce it if necessary. In the last one ren case it is appropriate depending on the length of the sheet each elastic strips (19) on the print to arrange the cylinder (5).
