Abstract
Abstract This invention relates to apparatus for performing so-called ''''needling'''' operations on textile goods, which apparatus is characterized by the fact that it comprises a needle support member having a multiplicity of felting needles affixed thereto, the long axes of which are oriented substantially normal to the surface of said member, and an associated backing member to support the textile material against the forces experienced during the needling operation, which backing member has a surface comprising pressure-tolerant, laterally displaceable, elongated members which are affixed at one end to the surface of the backing member and have their long axes oriented substantially normal to the surface of said backing member; said needle support member and said backing member each being so structured as to travel repeatedly along a closed travel path each aggregating 360* of angular change and being so positioned with respect to each other that at least at one point along their paths of travel, portions of said needles reside among said elongated members.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
139 words
An apparatus for needling textiles comprising a needle support member which is capable of traveling along a closed travel path and has a multiplicity of felting needles affixed thereto, the long axes of which are oriented substantially normal to the surface of said member, and a backing member which is capable of traveling along a closed travel path and has a surface comprising pressuretolerant, laterally displaceable, elongated fabric support members which are affixed at one end to the surface of said backing member and have their long axes oriented substantially normal to the surface of said backing member; said closed travel paths each aggregating 360* of angular change and being so positioned with respect to each other that at least at one point along said paths, a portion at least of said needles will reside among said elongated members.
Claim 2
Independent Claim
139 words
An apparatus for needling textiles comprising a needle support member which is capable of traveling along a closed travel path and has a multiplicity of felting needles affixed thereto, the long axes of which are oriented substantially normal to the surface of said member, and a backing member which is capable of traveling along a closed travel path and has a surface comprising pressuretolerant, laterally displaceable, elongated fabric support members which are affixed at one end to the surface of said backing member and have their long axes oriented substantially normal to the surface of said backing member; said closed travel paths each aggregating 360* of angular change and being so positioned with respect to each other that at least at one point along said paths, a portion at least of said needles will reside among said elongated members.
Claim 3
Dependent Claim
16 words
The apparatus described in claim 1 wherein said surface of said backing member comprises card wire.
Claim 4
Dependent Claim
17 words
The apparatus described in claim 1 in which at least one of said members is a cylinder.
Claim 5
Dependent Claim
17 words
The apparatus described in claim 2 in which at least one of said members is a cylinder.
Claim 6
Dependent Claim
17 words
The apparatus described in claim 1 in which said needle member and said backing member are cylinders.
Claim 7
Dependent Claim
17 words
The apparatus described in claim 5 in which said surface of said backing member comprises card wire.
Claim 8
Dependent Claim
30 words
The apparatus described in claim 5 wherein the diameter of said needle-bearing cylinder is at least 122 centimeters and the diameter of said backing cylinder is at least 30 centimeters.
Claim 9
Dependent Claim
22 words
The apparatus described in claim 5 wherein the diameter of said needle-bearing cylinder is equal to the diameter of said backing cylinder.
Claim 10
Dependent Claim
22 words
The apparatus described in claim 6 wherein the diameter of said needle-bearing cylinder is equal to the diameter of said backing cylinder.
Claim 11
Independent Claim
122 words
A method of needling textiles comprising the steps of moving a fabric through the point of closure between a needle support member having needles affixed thereto the long axes of which are oriented substantially normal to the surface of said support member, and a backing member having pressure tolerant, laterally displaceable elongated fabric support members affixed at one end to the surface thereof, the long axes of which are oriented substantially normal to the surface of said backing member, moving said members along closed travel paths each aggregating 360* of angular change, positioning said members with respect to each other so that at least at one point along said paths, a portion at least of said needles will reside among said members.
Claim 12
Independent Claim
122 words
A method of needling textiles comprising the steps of moving a fabric through the point of closure between a needle support member having needles affixed thereto the long axes of which are oriented substantially normal to the surface of said support member, and a backing member having pressure tolerant, laterally displaceable elongated fabric support members affixed at one end to the surface thereof, the long axes of which are oriented substantially normal to the surface of said backing member, moving said members along closed travel paths each aggregating 360* of angular change, positioning said members with respect to each other so that at least at one point along said paths, a portion at least of said needles will reside among said members.
Claim 13
Dependent Claim
22 words
A method according to claim 10 wherein at least one of said members is a cylinder rotating 360* about it''s longitudinal axis.
Claim 14
Independent Claim
173 words
An apparatus for needling textiles comprising a needle support member which is capable of traveling along a closed travel path and has a multiplicity of felting needles affixed thereto, the long axes of which are oriented substantially normal to the surface of said member, and a backing member which is capable of traveling along a closed travel path and has a surface comprising pressure-tolerant, laterally displaced, elongated fabric support members which are affixed at one end to the surface of said backing member and having their long axes oriented substantially normal to the surface of said backing member; said closed travel paths each aggregating 360* of angular change and being so positioned with respect to each other that at least at one point along said paths, a portion at least of said needles will reside among said elongated members, said support member being movable relative to said backing member to control the distance between said needLe and backing members and thereby control the depth at which said needles reside among said elongated members.
Claim 15
Independent Claim
173 words
An apparatus for needling textiles comprising a needle support member which is capable of traveling along a closed travel path and has a multiplicity of felting needles affixed thereto, the long axes of which are oriented substantially normal to the surface of said member, and a backing member which is capable of traveling along a closed travel path and has a surface comprising pressure-tolerant, laterally displaced, elongated fabric support members which are affixed at one end to the surface of said backing member and having their long axes oriented substantially normal to the surface of said backing member; said closed travel paths each aggregating 360* of angular change and being so positioned with respect to each other that at least at one point along said paths, a portion at least of said needles will reside among said elongated members, said support member being movable relative to said backing member to control the distance between said needLe and backing members and thereby control the depth at which said needles reside among said elongated members.
Claim 16
Dependent Claim
17 words
The apparatus described in claim 12 in which at least one of said members is a cylinder.
Claim 17
Dependent Claim
17 words
The apparatus described in claim 13 in which said needle member and said backing member are cylinders.
