## Abstract

A rotating filler cam system including a lower die receiving at least one filler cam. The filler cam includes saddles that sit in saddle pockets of the lower die such that the filler cam is rotatably connected to the lower die. At least one wedge assembly is driven to contact the filler cam and rotate the filler cam from a first position to a second position.

## Claims

### Claim 1

A wedge activated rotating cam system comprising:
a rotating filler cam having a first end with a first saddle and a second end with a second saddle;
a lower die having a first end with a first saddle pocket for receiving the first saddle and a second end with a second saddle pocket for receiving the second saddle;
a first saddle keeper positioned within the first saddle; and
a first keeper located on the first end of the lower die and being adapted to maintain the first saddle keeper within the first saddle.

### Claim 2 (depends on 1)

The system of claim 1, further comprising:
a second saddle keeper positioned within the second saddle; and
a second keeper located on the second end of the lower die and being adapted to maintain the second saddle keeper within the second saddle.

### Claim 3 (depends on 1)

The system of claim 1, further comprising:
a wedge connected to a drive mechanism, said wedge being driven by the drive mechanism to engage a portion of said filler cam and to rotate said filler cam from a first position to a second position.

### Claim 4 (depends on 3)

The system of claim 3, further comprising a wear plate positioned between said wedge and the filler cam, wherein said wedge comprises a wedge plate keeper adapted to maintain the wedge plate during rotation of the filler cam.

### Claim 5 (depends on 3)

The system of claim 3, wherein said wedge and the first and second saddles are located below the rotational axis of the filler cam.

### Claim 6 (depends on 1)

The system of claim 1, wherein the saddles and the saddle pockets allow the filler cam to be rotated from a first position to a second position.

### Claim 7

A wedge activated rotating cam assembly comprising:
a rotating filler cam having a first end with a first saddle and a second end with a second saddle;
a lower die having a first end with a first saddle pocket for receiving the first saddle and a second end with a second saddle pocket for receiving the second saddle;
first and second saddle keepers respectively positioned within the first and second saddles;
first and second keepers respectively located on the first and second ends of the lower die; and
a plurality of wedges adapted to be driven by a drive mechanism to engage portions of said filler cam and to rotate said filler cam from a first position to a second position.

### Claim 8 (depends on 7)

The system of claim 7, wherein the first and second keepers are adapted to maintain the first and second saddle keepers within the first and second saddles.

### Claim 9 (depends on 7)

The system of claim 7, further comprising wear plates positioned between said wedges and the filler cam, wherein said wedges comprise wear plate keepers adapted to maintain the slide plates during rotation of the filler cam.

### Claim 10 (depends on 7)

The system of claim 7, wherein said wedges and the first and second saddles are located below the rotational axis of the filler cam.

### Claim 11 (depends on 10)

The system of claim 10, wherein said wedges are constructed as a single piece of steel.
