A delivery for a sheet-processing machine for keeping the extent thereof required downline from the delivery pile as short as possible, includes a frame and grippers revolvable, during operation, along a gripper path within the frame. The grippers seize sheets at a location on the gripper path and drag the sheet along sections of the gripper path in a transport direction. A first switching element is provided, for defining a first end of a first one of the sections of the gripper path located downline with respect to the transport direction. A second switching element defines a second end of a second section of the gripper path located downline with respect to the end of the first section. The first switching element is provided on the frame, and the second switching element is provided on a guide part fixed to the frame, and serves for determining a section of a course of the gripper path.

1. In a sheet-processing machine, a delivery comprising a frame, grippers revolvable, during operation, along a gripper path within said frame, said grippers serving for seizing a respective one of the sheets at a location on said gripper path and for dragging the sheet along sections of said gripper path in a transport direction, a first switching element, by which a first end of a first one of said sections of said gripper path, disposed downline with respect to said transport direction, is definable, and a second switching element, by which a second end of a second section of said gripper path, disposed downline with respect to the end of the first section, is definable, said first switching element being disposed on said frame, and said second switching element being disposed on a guide part fixed to said frame, and serving for determining a section of a course of said gripper path. 2. The delivery according to claim 1, wherein said switching elements are adjustable between a respective switching position and a respective ineffective position and the reverse. 3. The delivery according to claim 2, wherein one of said two switching elements is in said switching position thereof when the other of said two switching elements is adjusted into said ineffective position thereof, and the reverse. 4. The delivery according to claim 2, wherein said first switching element is adjustable from said respective switching position thereof into the respective ineffective position by being liftable with respect to the gripper path, and said second switching element being adjustable from the respective switching position into the respective ineffective position by being movable laterally off the gripper path. 5. The delivery according to claim 1, including a coupling mechanism attached to said frame, said coupling mechanism having a coupler forming said first switching element. 6. The delivery according to claim 5, wherein said coupling mechanism includes a first rocker pivotable about a locally fixed, first geometric axis and a second rocker pivotable about a second geometric axis and having a position that is adjustable. 7. The delivery according to claim 6, wherein said second geometric axis is adjustable to geometric locations on a circular path. 8. The delivery according to claim 1, including a pivot arm attached to said guide part and carrying said second switching element. 9. The delivery according to claim 2, wherein said switching elements are connected kinematically to one another. 10. The delivery according to claim 9, including a spring for biasing said second switching element with an actuating force in a direction towards said switching position thereof, and a control cam adjustable while said first switching element is being adjusted, and by which said second switching element is adjustable from said switching position thereof into said ineffective position thereof counter to said actuating force and, under the action of said actuating force, is adjustable from said ineffective position thereof into said switching position thereof. 11. The delivery according to claim 1, wherein said frame has a side wall. 12. The delivery according to claim 1, wherein said guide part is a deflection rail arrangement.
