Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
190 words
An apparatus for the treatment of endless textile material lengths which comprises a closed container means adapted to contain a treatment liquor and having a conveying zone and a dwell zone, partition means dividing said dwell zone into two channels each in communication with each other and in communication with said conveying zone, sieve drum means subjected to a suction draft rotatably disposed in the conveying zone, said sieve drum means and said channels being arranged so that said textile material is conveyed in a continuous manner from said sieve drum means into one of said channels around said partition means and through said other channel to said sieve drum means, plait means disposed in said one channel immediately adjacent to said sieve drum means for introducing said textile material into the one channel of said dwell zone, said plait means moving said material to and fro thereby plaiting said material whereby said material is conveyed in a tension-free state through said channels and guide means disposed in said other channel immediately preceeding said sieve drum means for effecting plait-free feeding of said textile material onto said sieve drum means.
Claim 2
Independent Claim
190 words
An apparatus for the treatment of endless textile material lengths which comprises a closed container means adapted to contain a treatment liquor and having a conveying zone and a dwell zone, partition means dividing said dwell zone into two channels each in communication with each other and in communication with said conveying zone, sieve drum means subjected to a suction draft rotatably disposed in the conveying zone, said sieve drum means and said channels being arranged so that said textile material is conveyed in a continuous manner from said sieve drum means into one of said channels around said partition means and through said other channel to said sieve drum means, plait means disposed in said one channel immediately adjacent to said sieve drum means for introducing said textile material into the one channel of said dwell zone, said plait means moving said material to and fro thereby plaiting said material whereby said material is conveyed in a tension-free state through said channels and guide means disposed in said other channel immediately preceeding said sieve drum means for effecting plait-free feeding of said textile material onto said sieve drum means.
Claim 3
Dependent Claim
66 words
The apparatus of claim 1, wherein the treatment liquor fills the dwell zone and establishes a level into the conveying zone up to the point where the textile material is transferred from the treatment liquor to the sieve drum means or the point where the textile material is removed from the sieve conveying means and reintroduced into the treatment liquor for conveyance through the dwelling zone.
Claim 4
Dependent Claim
24 words
The apparatus of claim 2, wherein heating means are disposed in the dwell zone of the container below the level of the treatment liquor.
Claim 5
Dependent Claim
29 words
The apparatus of claim 1, wherein the treatment liquor fills the dwell zone and the sieve drums means is completely immersed in the treatment liquor in the conveying zone.
Claim 6
Dependent Claim
25 words
The apparatus co claim 4, wherein heating means are disposed in the conveying zone of the container near the surface of the sieve drum means.
Claim 7
Dependent Claim
32 words
The apparatus of claim 1, wherein a baffle plate means is disposed inside of that portion of the sieve drum means which is not in contact with the textile material being treated.
Claim 8
Dependent Claim
31 words
The apparatus of claim 1, wherein the cross section of the container means is key-hole shaped and the perforated drum is disposed in the upper, wide portion of said container means.
Claim 9
Dependent Claim
25 words
The apparatus of claim 1, wherein the top of the conveying zone of the container is provided with a filling hole and an airtight lid.
Claim 10
Dependent Claim
21 words
The apparatus of claim 1, wherein the two channels communicated with each other in the lower portion of the dwell zone.
Claim 11
Dependent Claim
59 words
The apparatus of claim 1, wherein the partition means extends from a point close to the bottom surface of the sieve drum To the lower portion of the dwell zone, said partition means terminating at a point sufficiently above the bottom of the dwell zone to enable the conveyance of the textile material from one channel to the other.
Claim 12
Dependent Claim
24 words
The apparatus of claim 1, wherein said guide means comprises a plurality of driven guide rollers disposed immediately subjacent to said sieve drum means.
Claim 13
Dependent Claim
31 words
The apparatus of claim 1, wherein said plait means also causes a rhythmical movement of the treatment liquor through said dwell zone in the direction of travel of said textile material.
