A roller cover and associated pair of cams attachable to opposite ends of the roller cover. Each of the cams has an outer diameter extending radially outwardly beyond an outer diameter of the roller cover a predetermined distance for maintaining the outer diameter of the roller cover a corresponding distance from the surface being coated during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface.

In one aspect, methods of making a carbon coating are described herein. In some implementations, a method of making a carbon coating comprises applying a first adhesive material to a substrate surface to provide an adhesive surface; rolling a carbon source over the adhesive surface to provide a carbon layer on the adhesive surface; and rolling an adhesive roller over the carbon layer to remove some but not all of the carbon of the carbon layer to provide the carbon coating.

A paint roller sleeve assembly and a method for washing it for reuse. The sleeve assembly includes a core of a size to fit a conventional paint roller handle. The core is compressible by hand radially, to allow a tubular flexible outer cover including a backing layer and a layer of paint-carrying fiber pile to be removed for washing and thereafter be replaced on the core for reuse.

A paint applicator having improved paint-carrying capacity, release, and coverage. The applicator includes a paint-carrying surface that is treated with a silicone emulsion, a silicone emulsion comprised of a nonionic macro-emulsion of a functional polysiloxane, or a mixture thereof. Also provided is a method for treating such paint applicators in which a silicone emulsion is applied to the paint-carrying surface, and subsequently dried and cured.

The invention provides: a method for applying a liquid to the rim of a container by transfer from a roller whose surface is composed of a tubular warp or weft knit of 21 rib construction; a glass jar or equivalent container whose rim has a coating of varnish, adhesion promoter or heat-sealing primer formed by an application method; a jar or equivalent container comprising a seal heat-sealed to the rim.

Described are methods of making a paint roller using thermoplastic strip material, adhesive and a composite cover material. The materials can be assembled in a continuous manufacturing process by helically winding a strip comprising polypropylene around a mandrel so as to form a helically wound strip, advancing the wound strip along the mandrel, applying a molten layer of adhesive comprising polypropylene onto the outer surface of the wound strip, wrapping a strip of composite cover material about the wound strip and over the layer of adhesive, and allowing the adhesive to cool, thereby laminating the composite cover material with the outer surface of the wound strip.

A retention assembly for a hollow tubular decorating roller comprising a fixed mount member that is securable in use to a roller frame. The fixed mount member includes a first primary support formation and a first retention formation that extends radially beyond the first primary support formation. The retention assembly also includes a separable mount member that is selectively couplable with the fixed mount member. The separable mount member includes a second primary support formation and a second retention formation that extends radially beyond the second primary support formation. The first and second primary support formations are received, in use, by a respective end of a hollow tubular decorating roller. The first and second retention formations cooperate with one another while the separable mount member is coupled with the fixed mount member to in use retain a hollow tubular decorating roller therebetween.

A thin highly-open fabric or sleeve is placed over a paint roller cover, allowing the flow of paint in and out of the roller cover and smoother paint films.

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.
