Abstract

A sheet-transporting element includes suction openings for holding print sheets, longitudinal sliders including air passages, and transverse sliders including air passages. The longitudinal sliders and the transverse sliders are disposed in a cross-wise configuration and are movable into different positions corresponding to various sheet formats in the positions blocking selected ones of the suction openings.

First claim

The invention claimed is:

1. A sheet-transporting element, comprising:
suction openings for holding print sheets;
longitudinal sliders including first air passages;
transverse sliders including second air passages;
said longitudinal sliders and said transverse sliders being disposed in a crosswise configuration and being movable into switching positions corresponding to different sheet formats for blocking different ones of said suction openings;
a first actuating drive for switching said longitudinal sliders;
a first spindle drive connected to said first actuating drive; and
a first longitudinal slider switch and a second longitudinal slider switch supported on said first spindle drive for linear movement;
said first spindle drive having a right-hand thread screwed into said first longitudinal slider switch and a left-hand thread screwed into said second longitudinal slider switch.

2. The sheet-transporting element according to claim 1 , wherein said first actuating drive is a first motor.

3. The sheet-transporting element according to claim 1 , which further comprises a second actuating drive for switching said transverse sliders.

4. The sheet-transporting element according to claim 3 , wherein said second actuating drive is a second motor.

5. The sheet-transporting element according to claim 3 , which further comprises:
a second spindle drive connected to said second actuating drive; and
a transverse slider switch being adjusted by said second spindle drive.

6. The sheet-transporting element according to claim 5 , wherein the sheet-transporting element is a tray and said transverse slider switch is configured for linear movement.

7. The sheet-transporting element according to claim 5 , wherein the sheet-transporting element is a drum and said transverse slider switch is supported to pivot.

8. A sheet-transporting element, comprising:
suction openings for holding print sheets;
longitudinal sliders including first air passages;
transverse sliders including second air passages;
said longitudinal sliders and said transverse sliders being disposed in a crosswise configuration and being movable into switching positions corresponding to different sheet formats for blocking different ones of said suction openings;
a first actuating drive for switching said longitudinal sliders;
a first spindle drive connected to said first actuating drive;
a first longitudinal slider switch and a second longitudinal slider switch supported on said first spindle drive for linear movement; and
cam followers disposed on said longitudinal sliders, said first longitudinal slider switch and said second longitudinal slider switch including switching cams entering into switching contact with said cam followers.

9. A sheet-transporting element, comprising:
suction openings for holding print sheets;
longitudinal sliders including first air passages;
transverse sliders including second air passages;
said longitudinal sliders and said transverse sliders being disposed in a crosswise configuration and being movable into switching positions corresponding to different sheet formats for blocking different ones of said suction openings;
an actuating drive for switching said transverse sliders;
a spindle drive connected to said actuating drive;
a transverse slider switch being adjusted by said spindle drive; and
cam followers disposed on said transverse sliders, said transverse slider switch including a switching cam entering into switching contact with said cam followers.
