Delivery for a machine processing flat printing materials

A delivery for a sheet-processing rotary printing machine having a frame and processing flat sheets in a transport direction along a transport path, the transport path defining a transport generatrix, the delivery comprising:

• circulating gripper systems each dragging a sheet in the transport direction along the transport path during operation of the printing machine and selectively releasing the sheet at one of:
• a first location on the transport path to form a sheet stack;
• and
• a second location on the transport path downstream of the first location with respect to the transport direction;
• a suction belt conveyer having a geometric axis parallel to the transport generatrix of the transport path, said suction belt conveyer including suction belt modules each having:
• a first roller;
• a second roller disposed downstream of said first roller with respect to the transport direction;
• and
• a conveying run connected to said first roller and to said second rollers and running from said first roller to said second roller during operation of the printing machine;
• a crossmember:
• defining said geometric axis,
• pivotably mounted in the frame about said geometric axis,
• selectively adjustable to different pivoting positions, and
• carrying and adjusting said suction belt conveyor to different working positions by pivoting about said geometric axis;
• said conveying run of each of said suction belt modules forming a variable support surface for a sheet released at the second location, said variable support surface defining a support generatrix oriented parallel to the transport generatrix of the transport path;
• and
• a physical position of said support surface being variable while maintaining an orientation of said support generatrix.

In a sheet-processing rotary printing machine processing flat sheets in a transport direction along a transport path, the transport path defining a transport generatrix, a sheet delivery comprising:

• circulating gripper systems each dragging the sheet in the transport direction along the transport path during operation of the printing machine and selectively releasing the sheet at one of:
• a first location on the transport path La form a sheet stack;
• and
• a second location on the transport path downstream of the first location with respect to the transport direction;
• a suction belt conveyer with suction belt modules each having:
• a first roller;
• a second roller disposed downstream of said first roller with respect to the transport direction;
• and
• a conveying run connected to said first roller and to said second rollers and running from said first roller to said second roller during operation of the printing machine;
• said suction belt modules being adjustable between a working position and a position located away from said working position;
• a locking device releasably fixing each of said suction belt modules in said working position;
• and
• said locking device releasing a respective one of said suction belt modules from said working position through a transverse force loading said conveying run of said one suction belt module;
• said conveying run of each of said auction belt modules forming a variable support surface for a sheet released at the second location, said variable support surface defining a support generatrix oriented parallel to the transport generatrix of the transport path;
• and
• a physical position of said support surface being variable while maintaining an orientation of said support generatrix.
