Abstract
Abstract The crease displacement and the achievable dilution factor in the conventional continuous pretreatment or aftertreatment operations of fabric ropes with liquid means in rope washers are not adequate, and consequently the water consumption necessary for satisfactory results is too high. To date the existing problems can only be solved with squeeze rollers which, however, have an adverse effect on the goods. According to the invention the textile rope is now introduced into a treatment store of a liquid-operated jet apparatus, is subjected to the action of the treatment liquor, is then carried along by a steam- or more generally gas-operated jet arrangement and conveyed into an interim store, where dewatering takes place. From the interim store the goods, with satisfactory dilution factor, are then passed to the next isothermal or non-isothermal treatment stage of the same or a very similar structure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
A process for treating textile woven or knitted fabric rope guided through jet apparatus during the continuous passage of the rope through various successive but separate wet-treatment zones of the apparatus, the process comprising the steps of supplying a treatment liquor to the textile rope entering a wet-treatment zone as the rope passes through a liquid-operated jet arranged to move the rope along its path of travel, simultaneously forcing the rope into an immediately following storage space filled with the same treatment liquid, where the continuously moving rope is subjected to the action of the treatment liquid, continuously removing the textile rope thus wet-treated from the storage space by a downstream steam- or gas-operated jet, and feeding the rope into a subsequent interim store where the continuously moving rope is largely freed of the previously applied treatment liquid.
Claim 2
Dependent Claim
138 words
A process for treating textile woven or knitted fabric rope guided through jet apparatus during the continuous passage of the rope through various successive but separate wet-treatment zones of the apparatus, the process comprising the steps of supplying a treatment liquor to the textile rope entering a wet-treatment zone as the rope passes through a liquid-operated jet arranged to move the rope along its path of travel, simultaneously forcing the rope into an immediately following storage space filled with the same treatment liquid, where the continuously moving rope is subjected to the action of the treatment liquid, continuously removing the textile rope thus wet-treated from the storage space by a downstream steam- or gas-operated jet, and feeding the rope into a subsequent interim store where the continuously moving rope is largely freed of the previously applied treatment liquid.
Claim 3
Dependent Claim
28 words
The process as claimed in claim 1, including the step of assisting the movement of the rope along its path of travel by means of a driven winch.
Claim 4
Dependent Claim
29 words
The process as claimed in claim 1, including the step of passing the treatment liquor through the successive wet-treatment stages countercurrent to the path of travel of the rope.
Claim 5
Dependent Claim
19 words
The process as claimed in claim 1, wherein the individual successive wet-treatment stages are carried out under isothermal conditions.
Claim 6
Dependent Claim
24 words
The process as claimed in claim 1, including the step of spraying the textile rope immediately before it enters the steam- or gas-operated jet.
Claim 7
Independent Claim
91 words
An apparatus for treating textile woven or knitted fabric rope comprising a liquid-operated jet arranged to receive and move the rope along its path of travel, an immediately following storage space holding treatment liquor and arranged to receive the passing textile rope, a steam- or gas-operated jet arranged downstream of the storage space to receive and move the rope along its path of travel, and an interim store directly downstream from the steam- or gas-operated jet for receiving the textile rope and freeing the rope of the previously applied treatment liquid.
Claim 8
Independent Claim
91 words
An apparatus for treating textile woven or knitted fabric rope comprising a liquid-operated jet arranged to receive and move the rope along its path of travel, an immediately following storage space holding treatment liquor and arranged to receive the passing textile rope, a steam- or gas-operated jet arranged downstream of the storage space to receive and move the rope along its path of travel, and an interim store directly downstream from the steam- or gas-operated jet for receiving the textile rope and freeing the rope of the previously applied treatment liquid.
Claim 9
Dependent Claim
28 words
The apparatus as claimed in claim 6, including annular spray nozzles and drainage plates immediately upstream from the steam- or gas-operated jet for spraying the rope with liquid.
Claim 10
Dependent Claim
25 words
The apparatus as claim in claim 6, including annular suction nozzles immediately downstream from the steam- or gas-operated jet for removing liquid from the rope.
Claim 11
Dependent Claim
18 words
The apparatus as claimed in claim 6, wherein the interim store is double-walled with a perforated inner wall.
Claim 12
Dependent Claim
22 words
The apparatus as claimed in claim 6, wherein the interim store is double walled with an inner wall of side-by-side slide bars.
