Embodiment Construction

[0020] figure 1 A printing press 1 is shown, in which printing sheets 5 are printed by means of offset printing or inkjet printing. The printing press 1 has a stacker for collecting printed sheets 5 onto a stack. A chain gripper 2 is provided in the stacker, which transports the printed sheets 5 to the stack. The chain gripper 2 comprises two revolving chains which carry gripper bridges between them, which gripper bridges hold the front edges of the printed sheets 5 clamped. These gripper bridges move along the gripper bridge tracks 3 . The lower run of the two chains (Trume) runs through the powder air channel 4 .

[0021] along the transport direction 9 of the sheets 5 (see figure 2 ) Dust sheet 5 with powder before stacking. The dusting equipment required for this purpose is not shown together in the figures. The powder not adhering to the printing sheet 5 reaches the powder air channel 4 and is dragged away together with the chain gripper 2 .

Abstract

The invention relates to a method for operating a printing press, in which a printing sheet is conveyed along a gripper bridge track (3) in a powder air channel (4) by means of a chain gripper. An air curtain (7) is projected through the pneumatic seal (6), which intersects the gripper bridge track (3). In this case, at least one operating parameter of the pneumatic seal (6) is set as a function of at least one operating parameter of the printing press.

Description

technical field [0001] The invention relates to a method for operating a printing press, in which the printed sheets are transported in powder air ducts by means of chain grippers along gripper bridge rails, and an air curtain is ejected via pneumatic seals, which The air curtain intersects the gripper bridge track (kreuzt). Background technique [0002] In the third drawing of the document DE 196 43 747 A1, a device for applying a separating medium to a flat product is shown. In this device, the products are conveyed by means of a conveying device under separators. On the outlet-side end of the partition, an axial fan is arranged, the downwardly directed air flow of which generates an air curtain of the type which encloses the separating medium with respect to the conveying path ( Abkapselung), while the separating medium does not pass from the separator into the downstream section of the conveying path. [0003] The disadvantage of this is that the efficiency of axial f...
