## Abstract

The disclosure describes an improved paint roller wherein ribs are incorporated into either the roller core or the nap. Alternatively, the improved paint roller may use individual ribs positioned between the roller core and the nap. The incorporation of ribs into the roller core/nap assembly improves application of coating material to the nap and subsequent transfer of coating material to a surface.

## Claims

### Claim 1

A paint roller comprising:
a roller core;
a nap;
a rib positioned between said roller core and said nap.

### Claim 2 (depends on 1)

The paint roller of claim 1, wherein said rib runs transversely from one edge of said roller core to the opposing edge of said roller core.

### Claim 3 (depends on 1)

The paint roller of claim 1, wherein said rib spirals around said roller core.

### Claim 4 (depends on 1)

The paint roller of claim 1, wherein said rib is defined by a series of discrete protrusions.

### Claim 5 (depends on 1)

The paint roller of claim 1, wherein said rib is positioned on a bias from the central axis of said roller core.

### Claim 6 (depends on 1)

The paint roller of claim 1, wherein four ribs are equally positioned around said roller core and between said roller core and said nap.

### Claim 7 (depends on 6)

The paint roller of claim 6, wherein said ribs are integrally formed with said roller core.

### Claim 8 (depends on 7)

The paint roller of claim 7, wherein said ribs are incorporated into the composition of said nap.

### Claim 9 (depends on 1)

The paint roller of claim 1, wherein said rib is rigid.

### Claim 10 (depends on 9)

The paint roller of claim 9, wherein said rib has a height of about 10% to 25% of the thickness of nap.

### Claim 11 (depends on 1)

The paint roller of claim 1, wherein said rib is compressible.

### Claim 12 (depends on 11)

The paint roller of claim 11, wherein said rib has a height of about 10% to 100% of the thickness of nap.

### Claim 13 (depends on 1)

The paint roller of claim 1, wherein said rib is prepared from a material capable of flexing back and forth as said paint roller moves back and forth over a surface.

### Claim 14 (depends on 1)

The paint roller of claim 1, wherein said roller core further carries at least one open slot and said rib is positioned within said slot such that said ribs extends above the surface of the roller core.

### Claim 15 (depends on 1)

The paint roller of claim 1, wherein said roller core further carries at least one groove and said rib is positioned within said groove such that said ribs extends above the surface of the roller core.

### Claim 16 (depends on 14)

The paint roller of claim 14, wherein said open slot is at a non-perpendicular to the surface of the roller core.

### Claim 17 (depends on 15)

The paint roller of claim 15, wherein said groove is at a non-perpendicular to the surface of the roller core.

### Claim 18

A paint roller comprising:
a roller core;
a nap;
a rib positioned within said nap.

### Claim 19

A paint roller comprising:
a roller core;
a nap;
a rib integral with said roller core.

### Claim 20

A paint roller comprising:
a roller core having a slot passing through the surface of said roller core;
a nap;
a rib extending from the interior of said roller core through the surface of said roller core to a position above the surface of said roller core.

### Claim 21 (depends on 20)

The paint roller of claim 20, wherein said slot is configured to impart an angle different from a radial line extending from the axis of roller core.

### Claim 22

A paint roller comprising:
a roller core having a groove in the exterior surface of said roller core;
a nap;
a rib positioned within said groove and extending above the surface of said roller core.

### Claim 23 (depends on 22)

The paint roller of claim 22, wherein said groove is configured to support said rib at an angle different from a radial line extending from the axis of roller core.
