Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
100 words
A circular yarn pad having two composite layers for use on a floor cleaning machine, each of said layers comprising a flat primary substrate material, a plurality of yarn segments having a major proportion of each segment protruding from a first face of said primary substrate material in fixed relation thereto, a secondary backing material secured to a second face of said primary backing material, said second face being opposite from said first face, wherein said layers are securely joined with said backing materials in opposed relation and said first faces of said substrate materials directed in mutually opposite directions.
Claim 2
Dependent Claim
100 words
A circular yarn pad having two composite layers for use on a floor cleaning machine, each of said layers comprising a flat primary substrate material, a plurality of yarn segments having a major proportion of each segment protruding from a first face of said primary substrate material in fixed relation thereto, a secondary backing material secured to a second face of said primary backing material, said second face being opposite from said first face, wherein said layers are securely joined with said backing materials in opposed relation and said first faces of said substrate materials directed in mutually opposite directions.
Claim 3
Dependent Claim
21 words
The yarn pad of claim 1 wherein said yarn segments are uniformly distributed over the face of said primary substrate material.
Claim 4
Dependent Claim
15 words
The yarn pad of claim 1 wherein said yarn segments are substantially uniform in length.
Claim 5
Dependent Claim
27 words
The yarn pad of claim 1 wherein said layers are securely joined by means of a uniform adhesive layer interposed between said backing materials in opposed relation.
Claim 6
Dependent Claim
22 words
The yarn pad of claim 1 wherein said yarn segments are in the form of loops extending from said primary substrate material.
Claim 7
Dependent Claim
14 words
The yarn pad of claim 1 wherein said yarn segments are comprised of nylon.
Claim 8
Dependent Claim
14 words
The yarn pad of claim 1 wherein said yarn pad is annular in shape.
Claim 9
Independent Claim
159 words
A method of manufacturing a layered composite from which yarn pads may be cut, comprising the steps of: (a) affixing a plurality of yarn segments to protrude from a first face of a first section of substrate material; (b) securing a backing material to a second face of said first section of substrate material, said second face being opposite said first face; (c) affixing a plurality of yarn segments to protrude from a first face of a second section of substrate material; (d) securing a backing material to a second face of said second section of substrate material, said second face being opposite said first face; (e) affixing said first section of said substrate material and said second section of said substrate material together in backing material opposed configuration, thereby orienting said respective first faces of said first and said second substrate materials in mutually opposite directions and forming a layered composite from which yarn pads may be cut.
Claim 10
Independent Claim
159 words
A method of manufacturing a layered composite from which yarn pads may be cut, comprising the steps of: (a) affixing a plurality of yarn segments to protrude from a first face of a first section of substrate material; (b) securing a backing material to a second face of said first section of substrate material, said second face being opposite said first face; (c) affixing a plurality of yarn segments to protrude from a first face of a second section of substrate material; (d) securing a backing material to a second face of said second section of substrate material, said second face being opposite said first face; (e) affixing said first section of said substrate material and said second section of said substrate material together in backing material opposed configuration, thereby orienting said respective first faces of said first and said second substrate materials in mutually opposite directions and forming a layered composite from which yarn pads may be cut.
Claim 11
Independent Claim
154 words
A method of manufacturing a circular yarn pad comprising the steps of: (a) affixing a plurality of yarn segments to protrude from a first face of a first section of substrate material; (b) securing a backing material to a second face of said first section of substrate material, said second face being opposite said first face; (c) affixing a plurality of yarn segments to protrude from a first face of a second section of substrate material; (d) securing a backing material to a second face of said second section of substrate material, said second face being opposite said first face; (e) affixing said first section of said substrate material and said second section of said substrate material together in backing material opposed configuration, thereby orienting said respective first faces of said first and said second substrate materials in mutually opposite directions and forming a layered composite; (f) cutting said composite into a circular shape.
Claim 12
Independent Claim
154 words
A method of manufacturing a circular yarn pad comprising the steps of: (a) affixing a plurality of yarn segments to protrude from a first face of a first section of substrate material; (b) securing a backing material to a second face of said first section of substrate material, said second face being opposite said first face; (c) affixing a plurality of yarn segments to protrude from a first face of a second section of substrate material; (d) securing a backing material to a second face of said second section of substrate material, said second face being opposite said first face; (e) affixing said first section of said substrate material and said second section of said substrate material together in backing material opposed configuration, thereby orienting said respective first faces of said first and said second substrate materials in mutually opposite directions and forming a layered composite; (f) cutting said composite into a circular shape.
Claim 13
Dependent Claim
21 words
The method of claim 8 or 9 wherein said first and second substrate materials are affixed by application of an adhesive.
Claim 14
Dependent Claim
28 words
The method of claim 8 or 9 wherein said yarn segments are affixed uniformly over said respective first faces of said first and second sections of substrate material.
Claim 15
Dependent Claim
41 words
The method of claim 8 or 9 wherein a flat stiffening member is interposed between said first section of said substrate material and said second section of substrate material, immediately prior to said affixing of said first and second sections together.
