## Abstract

A device for processing substrates uses a separation system. Processed substrates can be separated into one or more waste parts and at least one blank. Improved flexibility for treating substrates is provided. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder has first openings and has a detachably secured packing having depressions in which perforations are formed, with at least one perforation covering at least one first opening. The stripping cylinder has a detachably secured packing having raised areas that correspond to the depressions.

## Claims

### Claim 1

A device for treating substrates comprising:
first and second processing cylinders defining a processing nip between which substrates being treated can pass, the substrates passing through the processing nip defined by the first and second processing cylinders being processed by tool parts carried by at least one of the first and second processing cylinders, the tool parts including at least one of cutting tools, punching tools, creasing tools, perforating tools and grooving tools;
a separation system located after, in a direction of substrate travel through the device for treating substrates, the first and second processing cylinders, the separating device separating each substrate, treated by the first and second processing cylinders, into at least one blank substrate section and at least one waste substrate section;
a transport cylinder in the separation system and having a plurality of first air openings;
a detachably secured transport cylinder packing on a circumferential surface of the transport cylinder, the detachably secured transport cylinder packing having a plurality of transport cylinder packing perforations and transport cylinder packing depressions, at least one of the transport cylinder packing perforations covering one of the plurality of transport cylinder packing first air openings, the transport cylinder packing depressions including ones of the perforations;
a stripping cylinder in the separation system and cooperating with the transport cylinder; and
a detachably secured stripping cylinder packing on the stripping cylinder, the stripping cylinder packing having a plurality of raised regions, which raised regions are receivable in the depressions in the transport cylinder packing.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the transport cylinder has a plurality of second air openings, and wherein a first air supply is provided to supply air to the plurality of first air openings and wherein a second air supply is provided to supply air to the plurality of second air openings, independently of the supply of air to the plurality of first air openings by the first air supply.

### Claim 3 (depends on 2)

The device according to claim 2, wherein each of the first and second air supply supplies air to its ones of the plurality of first and second air openings dependent upon an angular position of the ones of the plurality of first and second air openings to which air is being supplied.

### Claim 4 (depends on 2)

The device according to claim 2, wherein the plurality of first and second air supply openings are arranged in alternation in one of a circumferential direction of the transport cylinder and an axial direction of the transport cylinder and are configured as ones of grooves and holes.

### Claim 5 (depends on 2)

The device according to claim 2, wherein each of the first and second air supply comprises one of at least one rotary slide valve and at least one rotary inlet, and wherein the one of the at least one rotary slide valve and the at least one rotary inlet is formed on an end face of the transport cylinder.

### Claim 6 (depends on 5)

The device according to claim 5, wherein the at least one rotary inlet comprises a disk which is assigned to the end face of the transport cylinder.

### Claim 7 (depends on 1)

The device according to claim 1, wherein the device for treating substrates is a component of a sheet-fed printing machine.

### Claim 8 (depends on 1)

The device according to claim 1, wherein the transport cylinder has means for securing the transport cylinder packing on the circumferential surface of the transport cylinder.

### Claim 9 (depends on 8)

The device according to claim 8, wherein the means for securing the transport cylinder packing is one of a clamping element configured as a clamping jaw and a clamping gripper.

### Claim 10 (depends on 8)

The device according to claim 8, wherein the means for securing the transport cylinder packing carries positioning pins to position the packing.

### Claim 11 (depends on 8)

The device according to claim 8, wherein the transport cylinder gripper system is mounted on a means for securing the transport cylinder packing on the circumferential surface of the transport cylinder.

### Claim 12 (depends on 1)

The device according to claim 1, wherein the transport cylinder has a transport cylinder gripper system, embodied, as one of a suction gripper system and a clamping gripper system to secure a leading edge of each of the substrates to the transport cylinder.

### Claim 13 (depends on 12)

The device according to claim 12, wherein the transport cylinder gripper system generates a suction region, the length of which suction region, in an axial direction of the transport cylinder, is equal to a multiple of a length of the transport cylinder in a circumferential direction of the transport cylinder.

### Claim 14 (depends on 13)

The device according to claim 13, wherein the length of the suction region in the axial direction of the transport cylinder is adjustable.

### Claim 15 (depends on 1)

The device according to claim 1, wherein each of the first and second air supply can be switched between a suction air supply and a blower air supply.
