## Abstract

A turnbar for use in a turnover module in a printing system includes one or more air-cushioned sections and one or more friction sections. Each air-cushioned section includes holes formed in a portion of a perimeter of the turnbar. Each friction section includes a friction-inducing material disposed over or affixed to another portion of the perimeter of the turnbar. Pressurized air or gas is output through the holes to produce a cushion of air or gas between a print media and the air-cushioned section. The turnbar can include one or more pistons within the turnbar, or one or more sleeves within or around the turnbar, or a combination of pistons and sleeves, to adjust airflow through the air-cushioned section.

## Claims

### Claim 1

A turnbar for use in a turnover module comprising:
an air-cushioned section that includes a plurality of holes in a portion of a perimeter of the turnbar; and
a friction section that includes a friction-inducing material affixed to another portion of the perimeter of the turnbar positioned adjacent to the air-cushioned section.

### Claim 2 (depends on 1)

The turnbar as in claim 1, further comprising another air-cushioned section that includes a plurality of holes in a different portion of the perimeter of the turnbar.

### Claim 3 (depends on 2)

The turnbar as in claim 2, wherein an area of one air-cushioned section is different from an area of the other air-cushioned section.

### Claim 4 (depends on 1)

The turnbar as in claim 1, further comprising at least one piston inside the turnbar for adjusting an area of the air-cushioned section.

### Claim 5 (depends on 1)

The turnbar as in claim 1, further comprising a movable sleeve for adjusting a size of the air-cushioned section.

### Claim 6 (depends on 2)

The turnbar as in claim 2, further comprising at least one piston inside the turnbar for adjusting an area of at least one of the air-cushioned sections.

### Claim 7 (depends on 1)

The turnbar as in claim 1, wherein an area of the air-cushioned section is divided into zones and each zone is controlled individually to output air.

### Claim 8 (depends on 2)

The turnbar as in claim 2, wherein an area of at least one of the air-cushioned sections is divided into zones and each zone is controlled individually to output air.

### Claim 9

A turnover module comprising:
one or more turnbars, wherein at least one of the one or more turnbars includes
one or more air-cushioned sections, wherein each air cushioned section includes holes in a portion of a perimeter of the turnbar; and
one or more friction sections each including a friction-inducing material disposed over another portion of the perimeter of the turnbar.

### Claim 10 (depends on 9)

The turnover module as in claim 9, wherein an area of one air-cushioned section is different from an area of another air-cushioned section.

### Claim 11 (depends on 9)

The turnover module as in claim 9, further comprising at least one piston inside the at least one turnbar for adjusting an area of one or more air-cushioned sections.

### Claim 12 (depends on 9)

The turnover module as in claim 9, further comprising at least one movable sleeve for adjusting a size of one or more air-cushioned sections.

### Claim 13 (depends on 9)

The turnover module as in claim 9, wherein an area of the one or more air-cushioned sections is divided into zones and each zone is controlled individually to output air.
