## Abstract

A bale wrapping device for a round baler includes a wrapping material roller having a wrapping material. The wrapping material roller is able to be brought into engagement with a brake roller, and a cutting apparatus for cutting off the wrapping material from the wrapping material roller. A brake apparatus cooperates with the brake roller, and is actuatable by the cutting apparatus such that a rotational movement of the brake roller is able to be braked by the brake apparatus.

## Claims

### Claim 1

A bale wrapping device for a round baler, the bale wrapping device comprising:
a brake roller;
a wrapping material roller for supporting a wrapping material, wherein the wrapping material roller is selectively engageable with the brake roller;
a cutting apparatus configured for cutting off the wrapping material from the wrapping material roller;
a brake apparatus coupled to the brake roller and the cutting apparatus, wherein movement of the cutting apparatus actuates the brake apparatus such that rotational movement of the brake roller is braked by the brake apparatus in response to movement of the cutting apparatus.

### Claim 2 (depends on 1)

The bale wrapping device set forth in claim 1, wherein the cutting apparatus is movable between at least an active cutting position and an inactive cutting position, with the brake apparatus operable to brake rotational movement of the brake roller when the cutting apparatus is disposed in the active cutting position.

### Claim 3 (depends on 2)

The bale wrapping device set forth in claim 2, wherein the bale wrapping device includes an actuator operable to actuate the brake apparatus.

### Claim 4 (depends on 3)

The bale wrapping device set forth in claim 3, wherein the actuator is operable to move the cutting apparatus between the active cutting position and the inactive cutting position.

### Claim 5 (depends on 1)

The bale wrapping device set forth in claim 1, wherein the bale wrapping device includes a drive roller operable to feed the wrapping material into a baling chamber.

### Claim 6 (depends on 5)

The bale wrapping device set forth in claim 5, wherein the drive roller is connected to a drive apparatus.

### Claim 7 (depends on 1)

The bale wrapping device set forth in claim 1, wherein the brake apparatus includes a brake coupling fixedly connected in terms of rotation to the brake roller, and a brake lever coupled to the cutting apparatus, wherein the brake lever is actuatable in response to movement of the cutting apparatus to engage the brake coupling to brake the brake roller.

### Claim 8 (depends on 1)

The bale wrapping device set forth in claim 1, wherein the brake coupling includes at least one actuating element and the brake lever includes a first end having a brake element, wherein the actuating element is configured for gripping engagement with the brake element such that the brake element bears against the actuating element in response to movement of the brake lever.

### Claim 9 (depends on 1)

The bale wrapping device set forth in claim 1, the drive apparatus includes a combined drive and brake drum fixedly connected in terms of rotation to the drive roller.
