Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
11 words
A fabric made using the composite linear element of claim 1.
Claim 2
Dependent Claim
17 words
A composite linear element of claim 1 in which the coating on the central portion is discontinuous.
Claim 3
Dependent Claim
187 words
A composite linear element comprising: a linear bundle of glass filaments, the bundle including a central body of closely grouped glass filaments; a coating of elastomeric material impregnating the central body, the bundle further including surface filament portions along the length of the bundle, the surface filament portions comprising groups of dispersed glass filaments laterally extending from the central body beyond the outer surface of the coating on the central body between spaced apart locations; and a separate individual coating of the elastomeric material on individual dispersed glass filaments of the surface filament portions, the elastomeric material of the separate individual coatings being merged with the elastomeric material on the central body only in the regions where the dispersed surface filaments emerge from the central body to form a unitary coating on the bundle of glass filaments, the individual coating being sufficiently thin that the coated surface filaments project from the coated central body to be in spaced apart relationship with the outer surface of the coating on the central portion, substantially all of the spaces between the coated filaments and the coated central body being open.
Claim 4
Dependent Claim
178 words
A composite linear element for reinforcing elastomeric material comprising: continuous glass filaments tightly grouped together in a substantially parallel relationship into a central portion; a coating of elastomeric material impregnating the central portion; randomly spaced surface portions in which selected groups of dispersed filaments from the central portion extend outwardly from the outer surface of the coating on the central portion in undulatory waves having substantially less filament density than the central portion; and a separate individual coating of the elastomeric material on individual filaments of the selected groups of filaments of the surface portions, the flexible material of the separate individual coatings being merged with the flexible material on the central portion only in the regions where the dispersed surface filaments emerge from the central portion, the individual coatings being sufficiently thin that the coated surface filaments project from the coated central portion to be in spaced apart relationship with the outer surface of the coating on the central portion , substantially all of the spaces between the coated filaments and the coated central portion being open.
Claim 5
Dependent Claim
25 words
The composite linear element of claim 5 in which the elastomeric material of the coating on the central portion only partially impregnates the central portion.
Claim 6
Dependent Claim
22 words
The composite linear element of claim 5 in which the elastomeric material impregnates from 10 to 15 microns into the central portion.
Claim 7
Dependent Claim
16 words
The composite linear element of claim 1 in which the flexible coating material is a plastic.
Claim 8
Dependent Claim
177 words
A composite linear element for reinforcing elastomeric material comprising: continuous glass filaments tightly grouped together in a substantially parallel relationship into a central portion; a thin coating of elastomeric material on the central portion; randomly spaced surface portions in which selected groups of filaments from the central portion extend outwardly from the central portion beyond the outer surface of the coated central portion in undulatory waves having substantially less filament density than the central portion; and a separate individual coating of elastomeric material on individual filaments of the surface portions, the elastomeric material of the separate individual coatings being merged with the elastomeric material on the central portion only in the regions where the filaments of the surface portions emerge from the coated central portion and being sufficiently thin that the coated surface filaments project from the coated central portion to be in spaced apart relationship with the outer surface of the coating on the central portion, substantially all of the spaces between the coated filaments of the central portions and the coated central portion being open.
Claim 9
Dependent Claim
15 words
The composite linear element of claim 9 in which the elastomeric material is partially cured.
Claim 10
Dependent Claim
135 words
A composite linear element for reinforcing elastomeric material comprising: a linear bundle of glass filaments including a central body of closely grouped glass filaments extending lengthwise of the bundle and dispersed surface filaments extending laterally of the central body; a coating of elastomeric material on the central body; and a separate individual coating of the elastomeric material on the dispersed surface filament sufficiently thin that at least some of the dispersed surface filaments project in spaced apart relationship beyond the outer surface of the coating on the central body, substantially all of the spaces between the coated filaments and the coated central body being open, the coating material on the dispersed surface filaments merging with the coating material on the central body only in the regions where such surface filaments emerge from the central body.
