Abstract
Abstract An apparatus for treating a length of textile material which has a pile surface includes at least one sieve drum washing bath for washing the entire width of the textile material to even out or level irregularities across the width of the pile surface, a first steamer unit for treating the washed textile material, a dye applicator unit for applying dye to the steamed and washed textile material and a second steamer unit for treating the dye-containing textile material with steam to fix the dye to the textile material. The sieve drum washing bath includes a sieve drum positioned within a container for the treatment liquid and is provided with a plurality of nozzle openings arranged within the container and spaced closely adjacent to the sieve drum for directing the treatment liquid in the form of a plurality of jets across the width of the textile material being supported on the sieve drum.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
199 words
An apparatus for treating a length of textile material having a pile surface which comprises means for washing the entire width of the textile material with a treatment liquid to equalize irregularities across the width of the pile surface; a first steamer unit for treating the washed textile material to a steam-containing atmosphere; means for applying the dye to the steamed and washed textile material; and a second steamer unit for treating the dye-containing textile material with steam to fix the dye to the textile material; said washing means including at least one sieve drum washing bath comprising a rotatably mounted sieve drum positioned in a liquid container containing the treatment liquid, said sieve drum having a sieve surface for supporting the textile material, being at least partly immersed within the treatment liquid, and being so arranged within the container that the liquid flows from the outside to the inside of said sieve drum and a plurality of nozzle openings arranged within said container and spaced closely adjacent to said sieve drum surface for directing the treatment liquid in the form of a plurality of jets across the width of the textile material being supported on said sieve drum.
Claim 2
Independent Claim
199 words
An apparatus for treating a length of textile material having a pile surface which comprises means for washing the entire width of the textile material with a treatment liquid to equalize irregularities across the width of the pile surface; a first steamer unit for treating the washed textile material to a steam-containing atmosphere; means for applying the dye to the steamed and washed textile material; and a second steamer unit for treating the dye-containing textile material with steam to fix the dye to the textile material; said washing means including at least one sieve drum washing bath comprising a rotatably mounted sieve drum positioned in a liquid container containing the treatment liquid, said sieve drum having a sieve surface for supporting the textile material, being at least partly immersed within the treatment liquid, and being so arranged within the container that the liquid flows from the outside to the inside of said sieve drum and a plurality of nozzle openings arranged within said container and spaced closely adjacent to said sieve drum surface for directing the treatment liquid in the form of a plurality of jets across the width of the textile material being supported on said sieve drum.
Claim 3
Dependent Claim
30 words
An apparatus according to claim 1, further comprising a liquid suction drain means mounted downstream of the sieve drum washing bath for removing excess treatment liquid from said textile material.
Claim 4
Dependent Claim
61 words
An apparatus according to claim 1, wherein the first steamer unit comprises a steaming duct closed at the top and including means for guiding the textile material from the bottom to the top and from the top to the bottom, said guide means comprising a rotatably supported reversing roller for the textile material mounted at the top of said steaming duct.
Claim 5
Dependent Claim
29 words
An apparatus according to claim 3, wherein at least one impact roller is associated with the textile material along the path of the textile material within the steaming duct.
Claim 6
Dependent Claim
45 words
An apparatus according to claim 1, wherein said plurality of openings are arranged in form of mutually spaced slits over approximately 180° of the circumference of the sieve drum surface, said slits being provided by means extending across the operational width of the textile material.
Claim 7
Dependent Claim
68 words
An apparatus according to claim 5, wherein said means for providing said slits is a plurality of plates mounted concentrically around and close to the sieve surface of the sieve drum, said plates being provided with inwardly extending leg members, the leg members of adjacent plates together forming a slit through which the treatment liquid is passed in the form of a jet onto the sieve drum surface.
Claim 8
Dependent Claim
33 words
An apparatus according to claim 6, wherein said adjacent leg members are positioned to converge in the direction of the sieve drum thereby providing a tapered slit through which the treatment liquid passes.
Claim 9
Dependent Claim
46 words
An apparatus according to claim 5, wherein the liquid flow exiting from the slits is directed in the same direction as the direction of rotation in one portion of the sieve drum and opposite to the direction of rotation in another part of the sieve drum.
Claim 10
Dependent Claim
97 words
An apparatus according to claim 8, wherein said slits are defined by a plurality of plates mounted concentrically around and close to the sieve drum, said plates having leg members extending therefrom toward the sieve drum, the leg members of adjacent plates forming a slit therebetween, each slit being arranged to subtend an angle which on the upwardly moving portion of the sieve drum are slanted in the direction of the rotation of the sieve drum and on the downwardly moving portion of the sieve drum are slanted opposite to the direction of the sieve drum rotation.
Claim 11
Dependent Claim
23 words
An apparatus according to claim 9, wherein the two leg members forming a slit terminate at different distances from the sieve drum surface.
Claim 12
Dependent Claim
44 words
An apparatus according to claim 10, wherein the leg members defining a slit are, as seen in the direction of rotation of the sieve drum, first long and then short and in the second portion of the sieve drum, first short and then long.
Claim 13
Independent Claim
152 words
An apparatus for treating a length of textile material having a pile surface which comprises means for washing the entire width of the textile material with a treatment liquid to equalize irregularities across the width of the pile surface, said washing means including at least one sieve drum washing bath comprising a rotatably mounted sieve drum positioned in a liquid container containing the treatment liquid, said sieve drum having a sieve surface for supporting the textile material, being at least partly immersed within the treatment liquid, and being so arranged within the container that the liquid flows from the outside to the inside of said sieve drum, and a plurality of nozzle openings arranged within said container and spaced closely adjacent to said sieve drum surface for directing the treatment liquid in the form of a plurality of jets across the width of the textile material being supported on said sieve drum.
Claim 14
Independent Claim
