Abstract
Abstract A device for reducing splash and spray thrown from vehicle wheels comprising a high density polyethylene substrate layer fusion-bonded to a three-dimensional layer comprises a plurality of balde-like elements extending from a base layer. To improve break resistance at low temperture the three-dimensional layer comprises linear low density polyethylene.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
44 words
A laminated spray-suppression device comprising a substrate layer of high density polyethylene fusion bonded to a grass-like, three-dimensional layer having a plurality of elongated blades extending from a base layer, which is a substantially uniform sheet; said three-dimensional layer comprising linear low density polyethylene.
Claim 2
Dependent Claim
44 words
A laminated spray-suppression device comprising a substrate layer of high density polyethylene fusion bonded to a grass-like, three-dimensional layer having a plurality of elongated blades extending from a base layer, which is a substantially uniform sheet; said three-dimensional layer comprising linear low density polyethylene.
Claim 3
Dependent Claim
35 words
The device of claim 1 further comprising a non-woven fabric core layer intermediate the substrate layer and the grass-like, three-dimensional layer; wherein the fabric core layer is encapsulated on each side with an adhesive layer.
Claim 4
Dependent Claim
45 words
A laminated spray-suppression device comprising a substrate layer of high density polyethylene fusion bonded to a grass-like, three-dimensional layer of linear low density polyethylene having a plurality of blade-like elements extending from cup-like bases integrally molded to and located between parallel rows of rib-like elements.
Claim 5
Dependent Claim
45 words
A laminated spray-suppression device comprising a substrate layer of high density polyethylene fusion bonded to a grass-like, three-dimensional layer of linear low density polyethylene having a plurality of blade-like elements extending from cup-like bases integrally molded to and located between parallel rows of rib-like elements.
Claim 6
Dependent Claim
35 words
The device of claim 3 further comprising a non-woven fabric core layer intermediate the substrate layer and the grass-like, three-dimensional layer; wherein the fabric core layer is encapsulated on each side with an adhesive layer.
