## Abstract

A bale wrap mechanism for use with a roll of wrap material, the bale wrap mechanism including a frame including a wrap chute formed from one or more perimeter walls, where the wrap chute defines a wrap axis extending longitudinally therethrough, and where the one or more perimeter walls at least partially define a passageway, a wrap arm coupled to the frame, the wrap arm having a mounting point movable with respect to the frame, and a shaft coupled to the mounting point and configured to support the roll of wrap material thereon, where the shaft is configured to travel along a wrap path during a wrapping process, where the wrap path surrounds the passageway, and where the wrap path is non-circular in shape.

## Claims

### Claim 1

A bale wrap mechanism for use with a roll of wrap material, the bale wrap mechanism comprising:
a frame including a wrap chute formed from one or more perimeter walls, wherein the wrap chute includes a wrap axis extending longitudinally therethrough, and wherein the one or more perimeter walls at least partially define a passageway;
a first wrapping arm having a first end pivotably coupled to the frame and a second end opposite the first end;
a slider slidably coupled to the first wrapping arm and defining a mounting point, wherein the slider is movable with respect to the first wrapping arm between the first end and the second end of the first wrapping arm; and
a shaft coupled to the mounting point, wherein the shaft is configured to rotatably support the roll of wrap material thereon,
wherein the shaft is configured to travel along a wrap path during a wrapping process, wherein the wrap path surrounds the passageway, and wherein the wrap path is non-circular in shape.

### Claim 2 (depends on 1)

The bale wrap mechanism of claim 1, wherein the wrap path is rectangular in shape.

### Claim 3 (depends on 1)

The bale wrap mechanism of claim 1, wherein the passageway is rectangular in cross-sectional shape taken perpendicular to the wrap axis.

### Claim 4 (depends on 1)

The bale wrap mechanism of claim 1, further comprising a brake assembly configured to adjust the speed at which a length of wrap material is dispensed from the roll of wrap material.

### Claim 5 (depends on 1)

The bale wrap mechanism of claim 1, wherein first member is pivotable with respect to the frame about a first axis, and wherein the first axis is parallel the wrap axis.

### Claim 6 (depends on 1)

The bale wrap mechanism of claim 1, further comprising a brake assembly configured to adjust the tension of the wrap material dispensed from the roll of wrap material.

### Claim 7 (depends on 6)

The bale wrap mechanism of claim 6, wherein the brake assembly is configured to maintain a substantially constant applied tension profile for at least one complete cycle about the wrap path.
