Abstract
Abstract Apparatus for treating textile fabric in knitted or woven form for effecting relaxation thereof. An openwork conveyor structure supports and conveys the fabric under treatment. An abutment means of openwork construction is arranged in spaced opposed disposition relative to the conveyor structure. First and second treatment medium feed means are arranged in opposed disposition and are adapted to apply a treatment medium to the fabric. There is relative movement between the first and second treatment medium feed means in the feed direction of the conveyor structure to provide, at least periodically, oppositely directed displacement to the fabric at successive locations in the feed direction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
45 words
In or for a machine for the treatment of textile materials, opposed application means arranged in spaced apart disposition for passage of a textile material therebetween, the said application means being adapted for relative motion therebetween in the intended feed direction of the textile material.
Claim 2
Dependent Claim
45 words
In or for a machine for the treatment of textile materials, opposed application means arranged in spaced apart disposition for passage of a textile material therebetween, the said application means being adapted for relative motion therebetween in the intended feed direction of the textile material.
Claim 3
Dependent Claim
130 words
Apparatus for the treatment of textile fabric for effecting relaxation thereof comprising an openwork conveyor structure for supporting and conveying the fabric under treatment, an abutment means arranged in spaced opposed disposition relative to the support surface of the conveyor structure, the abutment means being of openwork construction, and first and second treatment medium feed means arranged in opposed disposition and adapted to apply a treatment medium to the fabric under treatment through the support surface of the conveyor structure and through the abutment means respectively, there being relative movement between the first and second treatment medium feed means, or parts thereof, in the feed direction of the conveyor structure to prOvide, at least periodically, oppositely directed displacement to the fabric at successive locations in the said feed direction thereof.
Claim 4
Dependent Claim
130 words
Apparatus for the treatment of textile fabric for effecting relaxation thereof comprising an openwork conveyor structure for supporting and conveying the fabric under treatment, an abutment means arranged in spaced opposed disposition relative to the support surface of the conveyor structure, the abutment means being of openwork construction, and first and second treatment medium feed means arranged in opposed disposition and adapted to apply a treatment medium to the fabric under treatment through the support surface of the conveyor structure and through the abutment means respectively, there being relative movement between the first and second treatment medium feed means, or parts thereof, in the feed direction of the conveyor structure to prOvide, at least periodically, oppositely directed displacement to the fabric at successive locations in the said feed direction thereof.
Claim 5
Dependent Claim
76 words
Apparatus as claimed in claim 2 wherein the first and second treatment medium feed means each include a plurality of nozzle members arranged in spaced disposition and directed transversely of the fabric under treatment, the said nozzles being movably mounted for cyclic oscillation about respective axes spaced from outlets to the said nozzles and extending in the transverse direction of the fabric, the oscillation of the said first and second feed means being out of phase.
Claim 6
Dependent Claim
25 words
Apparatus as claimed in claim 3 wherein the nozzle members of the first and second feed means are adapted to oscillate 180* out of phase.
Claim 7
Dependent Claim
23 words
Apparatus as claimed in claim 3 wherein the abutment comprises an openwork structure movable in synchronism with the movement of the conveyor structure.
Claim 8
Dependent Claim
26 words
Apparatus as claimed in claim 5 wherein the abutment is movable in synchronism with the movement of the conveyor structure and in the same direction thereas.
Claim 9
Dependent Claim
92 words
Apparatus for the treatment of a fabric comprising a support conveyor, an abutment means arranged in opposed disposition relative to the conveyor and first and second treatment medium feed means disposed behind a support surface of the support conveyor and an effective surface of the abutment means respectively for applying treatment medium to a fabric on the said support surface through such surfaces, the first and second such means being adapted to apply treatment medium to opposite sides of the fabric at successive spaced locations in the feed direction of the fabric.
Claim 10
Dependent Claim
92 words
Apparatus for the treatment of a fabric comprising a support conveyor, an abutment means arranged in opposed disposition relative to the conveyor and first and second treatment medium feed means disposed behind a support surface of the support conveyor and an effective surface of the abutment means respectively for applying treatment medium to a fabric on the said support surface through such surfaces, the first and second such means being adapted to apply treatment medium to opposite sides of the fabric at successive spaced locations in the feed direction of the fabric.
