Abstract
Abstract The procedure consists essentially of causing the corded fabric (4) to circulate in a continuous manner through a bath (3) of treatment liquid, and is characterized by the fact that the fabric (4) is subjected simultaneously to injection and spraying of the treatment bath liquid (3), by means of mixing air with the liquid, which separates into microparticles, the intake of the bath being effected from different points and at low pressure. The device comprises a substantially circular chamber (1), means (5) for the pulling of the fabric, with the fabric (4) circulating through a passageway defined between an outer plate (6) located next to the wall of the chamber (2) and an inner plate (7), and is characterized by the fact that it comprises a plurality of points (9, 10, 11, 12) of injection and spraying of the bath liquid along the entire run of the fabric (4) in the chamber (1). The plates (6, 7) form a spout (8) which facilitates the movement of the fabric ( 4). It also includes a grid (13) which permits better draining of the fabric (4). The dye is applied in a homogeneous manner.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
145 words
An apparatus for treating a corded fabric comprising; a chamber; a bath of treatment liquid within said chamber; means mounted within said chamber for continuously pulling said corded fabric; an inner plate and an outer plate, said inner plate and outer plate mounted within said chamber and together forming a passageway constituting a run through which said corded fabric can be continuously circulated; and a plurality of means for respectively spraying said corded microparticles formed by said treatment liquid having been mixed with air at a plurality of points within said chamber wherein said means for spraying comprise an overflow injector located adjacent said initial zone of said run, another injector located within said initial zone, still another injector located substantially at a point equidistant from an inner surface of said inner plate, and a shower element located in a receiving zone for said fabric.
Claim 2
Independent Claim
145 words
An apparatus for treating a corded fabric comprising; a chamber; a bath of treatment liquid within said chamber; means mounted within said chamber for continuously pulling said corded fabric; an inner plate and an outer plate, said inner plate and outer plate mounted within said chamber and together forming a passageway constituting a run through which said corded fabric can be continuously circulated; and a plurality of means for respectively spraying said corded microparticles formed by said treatment liquid having been mixed with air at a plurality of points within said chamber wherein said means for spraying comprise an overflow injector located adjacent said initial zone of said run, another injector located within said initial zone, still another injector located substantially at a point equidistant from an inner surface of said inner plate, and a shower element located in a receiving zone for said fabric.
Claim 3
Dependent Claim
66 words
The apparatus of claim 1, wherein said inner plate and said outer plate are located so as to be substantially parallel to each other throughout most of the run of said corded fabric but converge at an initial zone of said run to form thereby a spout which facilitates movement of said fabric such that the possibility of knot formation in said corded fabric is reduced.
Claim 4
Dependent Claim
63 words
The apparatus of claim 1, further comprising a closed distillation circuit connected to said chamber, said closed distillation circuit comprising a distillation column connected to said chamber, a condensation device connected to said distillation column, and a receptacle connected to said condensation device and directly to said chamber, said circuit functioning to enable the recovery of solvents from said bath of treatment liquid.
Claim 5
Dependent Claim
28 words
The apparatus of claim 1, further comprising means for controlling the viscosity of said bath of treatment liquid such that agglomerations of colorant particles therein are substantially avoided.
Claim 6
Dependent Claim
28 words
The apparatus of claim 1, further comprising means for controlling the viscosity of said bath of treatment liquid such that agglomerations of colorant particles therein are substantially avoided.
Claim 7
Dependent Claim
63 words
The apparatus of claim 1, further comprising a closed distillation circuit connected to said chamber, said closed distillation circuit comprising a distillation column connected to said chamber, a condensation device connected to said distillation column, and a receptacle connected to said condensation device and directly to said chamber, said circuit functioning to enable the recovery of solvents from said bath of treatment liquid.
Claim 8
Dependent Claim
50 words
The apparatus of claim 1, further comprising a grid formed by a plurality of bars on tubes, said grid abutting said outer plate so as to facilitate contact between said bath and said corded fabric, to facilitate self-expressing of said corded fabric, and to facilitate movement of said corded fabric.
Claim 9
Dependent Claim
43 words
The apparatus of claim 7, wherein said chamber comprises a plurality of openings in such arrangement that circulation of said treatment liquid through said grid forms arcs around said bars or tubes such that said microparticles are sprayed in a plurality of directions.
