Abstract
Abstract A running sole for a sports shoe and a method of manufacturing such a sole, wherein the carrier of woven fabric has fiber bristles projecting downwardly therefrom at least over certain areas of the carrier, the bristles being stiffened and glued to one another by impregnation with a synthetic resin, such as an epoxy resin adhesive, which is applied to the bristles by moving an applicator relative to the woven fabric carrier such that the fiber bristles come into contact with the applicator and take up the resin therefrom.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
39 words
A running sole for a sports shoe comprising a carrier, fiber bristles distributed at least over certain areas of said carrier and extending downwardly therefrom, and a synthetic resin impregnation stiffening and gluing said fiber bristles to one another.
Claim 2
Dependent Claim
39 words
A running sole for a sports shoe comprising a carrier, fiber bristles distributed at least over certain areas of said carrier and extending downwardly therefrom, and a synthetic resin impregnation stiffening and gluing said fiber bristles to one another.
Claim 3
Dependent Claim
29 words
A running sole as claimed in claim 1, wherein said carrier is a woven fabric with which the fiber bristles are interwoven and project therefrom is a velvet-like manner.
Claim 4
Dependent Claim
24 words
A running sole as claimed in claim 2, wherein the fiber bristles are arranged in the manner of a Manchester cloth in parallel ribs.
Claim 5
Dependent Claim
16 words

Claim 6
Dependent Claim
21 words
A running sole as claimed in claim 2, wherein the fiber bristles are arranged on said carrier in a specific pattern.
Claim 7
Dependent Claim
25 words
A running sole as claimed in claim 2, wherein the woven fabric carrier is formed from cotton and the fiber bristles are formed of polyester.
Claim 8
Dependent Claim
18 words
A running sole as claimed in claim 6 wherein the woven cotton fabric carrier is reinforced with polyester.
Claim 9
Dependent Claim
18 words
A running sole as claimed in claim 1 wherein the synthetic resin impregnation is a synthetic resin adhesive.
Claim 10
Dependent Claim
16 words
A running sole as claimed in claim 8, wherein the adhesive is an epoxy resin adhesive.
Claim 11
Dependent Claim
18 words
A running sole as claimed in claim 1, wherein the carrier is entirely free from synthetic resin impregnation.
Claim 12
Dependent Claim
21 words
A running sole as claimed in claim 1, wherein the carrier is adhesively secured to the insole of a sports shoe.
Claim 13
Dependent Claim
73 words
Method of manufacturing a running sole comprising the steps of forming a carrier with fiber bristles extending downwardly from at least certain areas of the carrier, uniformly feeding a synthetic resin impregnation to an applicator, displacing the carrier relative to the applicator such that the fiber bristles come into contact with the applicator and take up the synthetic resin therefrom, and cutting out the running sole to the desired shape from the carrier.
Claim 14
Dependent Claim
73 words
Method of manufacturing a running sole comprising the steps of forming a carrier with fiber bristles extending downwardly from at least certain areas of the carrier, uniformly feeding a synthetic resin impregnation to an applicator, displacing the carrier relative to the applicator such that the fiber bristles come into contact with the applicator and take up the synthetic resin therefrom, and cutting out the running sole to the desired shape from the carrier.
Claim 15
Dependent Claim
35 words
A method as claimed in claim 12, wherein the carrier is moved below the applicator so that the synthetic resin impregnation taken up by the fiber bristles runs a short distance along the fiber bristles.
Claim 16
Dependent Claim
15 words
A method as claimed in claim 12 wherein the applicator is a slit nozzle applicator.
Claim 17
Dependent Claim
15 words
A method as claimed in claim 12 wherein the applicator is a rotating drum applicator.
