Abstract
Abstract A cleated dust control mat (10) having a rubber or rubber-like backing in which the longitudinal edges (24) of the rubber-like backing (20) projecting outward from the pile surface thereon are smooth and thicker than the body of the rubber or rubber-like backing material. The thicker edges are produced by using a perforated silicone pad which is narrower than the desired width and has beveled edges thereon to provide a curved transition therein between the body and the longitudinal edges of the backing material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
57 words
A dust control mat comprising: a pile surface fabric, a rubber-like material connected to said pile surface fabric and extending beyond at least two edges of said pile surface fabric and a plurality of friction resistant cleats on the bottom of said rubber-like material under said pile surface fabric but not extending beyond the outer edges thereof.
Claim 2
Dependent Claim
57 words
A dust control mat comprising: a pile surface fabric, a rubber-like material connected to said pile surface fabric and extending beyond at least two edges of said pile surface fabric and a plurality of friction resistant cleats on the bottom of said rubber-like material under said pile surface fabric but not extending beyond the outer edges thereof.
Claim 3
Dependent Claim
37 words
The dust control mat of Claim 1 wherein the portion of said rubber-like material extending beyond the edges of said pile surface fabric is thicker than the body of said rubber-like material under said pile surface fabric.
Claim 4
Dependent Claim
14 words
The dust control mat of Claim 2 wherein the edges are approximately 10% thicker.
Claim 5
Dependent Claim
29 words
The dust control mat of Claim 3 wherein said rubber-like material has an arcuate shaped transition area between the body of the rubber-like material and the thicker edges thereof.
Claim 6
Dependent Claim
50 words
A pad for use in forming cleats in a rubber backed dust control mat comprising: a length of silicone or silicone-like material having two longitudinal edges, said longitudinal edges being cut at an angle of between 10° - 25° with a horizontal surface and a plurality of perforations formed therein.
Claim 7
Dependent Claim
50 words
A pad for use in forming cleats in a rubber backed dust control mat comprising: a length of silicone or silicone-like material having two longitudinal edges, said longitudinal edges being cut at an angle of between 10° - 25° with a horizontal surface and a plurality of perforations formed therein.
Claim 8
Dependent Claim
11 words
The pad of Claim 5 wherein said angle is approximately 10°.
Claim 9
Independent Claim
199 words
A method of forming a unitary dust control mat having a pile fiber upper surface and a rubber-like backing extending beyond at least two edges of the pile fiber upper surface comprising the steps of: placing a perforated silicone-like rubber material having a width less than the desired dust control mat on the surface of a conveyor belt, placing a strip of rubber-like material on top of the silicone-like pad so that its longitudinal edges overlap the edges of the silicone-like material, place a layer of pile fabric on top of the rubber-like material to form a layered structure, indexing the layered structure into a heated press molding machine, applying pressure to the layered structure in the press molding machine to vulcanize the rubber-like material and cause the rubber-like material to pass through the perforations in the silicone-like material to form cleats, causing the longitudinal edges to bend over the edges of the silicone-like material to form uncleated portions of a thickness greater than the body of the rubber-like material, indexing the vulcanized and adhered layered structure to a stripping station outside the press molding machine and stripping the composite structure from the conveyor belt and the silicone-like material.
Claim 10
Independent Claim
199 words
A method of forming a unitary dust control mat having a pile fiber upper surface and a rubber-like backing extending beyond at least two edges of the pile fiber upper surface comprising the steps of: placing a perforated silicone-like rubber material having a width less than the desired dust control mat on the surface of a conveyor belt, placing a strip of rubber-like material on top of the silicone-like pad so that its longitudinal edges overlap the edges of the silicone-like material, place a layer of pile fabric on top of the rubber-like material to form a layered structure, indexing the layered structure into a heated press molding machine, applying pressure to the layered structure in the press molding machine to vulcanize the rubber-like material and cause the rubber-like material to pass through the perforations in the silicone-like material to form cleats, causing the longitudinal edges to bend over the edges of the silicone-like material to form uncleated portions of a thickness greater than the body of the rubber-like material, indexing the vulcanized and adhered layered structure to a stripping station outside the press molding machine and stripping the composite structure from the conveyor belt and the silicone-like material.
Claim 11
Dependent Claim
19 words
The method of Claim 7 wherein the layered structure is preheated prior to passage into the press molding machine.
Claim 12
Independent Claim
172 words
The method of making a cleated, rubber backed dust control mat having at least two edges of greater thickness than the body of the rubber backing material, placing a perforated silicone-like pad having perforations therein and at two angled edges therein onto a conveyor belt, placing a rubber backing material over the silicone-like pad with the edges thereof extending beyond the angled edges of the silicone pad, placing a pile fabric on top of the rubber backing material to form a layered structure, placing the layered structure into a heated press molding machine, supplying heat and pressure to the layered structure to cause the rubber backing to be vulcanized to the pile fabric, and the rubber material to be forced through the perforations in the silicone-like pad to form cleats while the angled edges of the silicone pad are bent over by the rubber material to form uncleated, thicker rubber edges for the vulcanized dust control mat and stripping the vulcanized dust control mat off the conveyor belt and the silicone pad.
Claim 13
Independent Claim
172 words
The method of making a cleated, rubber backed dust control mat having at least two edges of greater thickness than the body of the rubber backing material, placing a perforated silicone-like pad having perforations therein and at two angled edges therein onto a conveyor belt, placing a rubber backing material over the silicone-like pad with the edges thereof extending beyond the angled edges of the silicone pad, placing a pile fabric on top of the rubber backing material to form a layered structure, placing the layered structure into a heated press molding machine, supplying heat and pressure to the layered structure to cause the rubber backing to be vulcanized to the pile fabric, and the rubber material to be forced through the perforations in the silicone-like pad to form cleats while the angled edges of the silicone pad are bent over by the rubber material to form uncleated, thicker rubber edges for the vulcanized dust control mat and stripping the vulcanized dust control mat off the conveyor belt and the silicone pad.
Claim 14
Dependent Claim
20 words
The method of Claim 9 wherein the layered structure is preheated prior to being supplied to the press molding machine.
