Method and apparatus for treating textile goods in rope form

Abstract

In a method for treating textile goods in rope form in a closed treatment tank, the textile goods are joined at the ends to form an endless rope. By means of a gaseous stream of feeder medium, made to act on the rope via feed nozzle means, a rotational motion inside the treatment tank is imparted to the rope. The rope emerging from the feed nozzle means is lapped, on entering a J-box located in the treatment tank, by the feed nozzle means itself, which execute a reciprocating motion.

       4 . The method as defined by  claim 1  wherein when a treatment tank is used that contains more than one J-box, separate feed nozzle means are used for each J-box.  
   
   
       5 . The method as defined by  claim 1  wherein the gaseous stream of feeder medium is generated by blower means, which are mounted on the treatment tank and are moved at least in part jointly with the feed nozzle means.  
   
   
       6 . An apparatus for treating textile goods in the form of at least one endless rope, having 
 a closable treatment tank;    at least one J-box, located in the treatment tank, for receiving the rope at least during part of the treatment period;    feeding means for feeding the rope, which have feed nozzle means through which the rope passes, with a rope inlet and a rope outlet, which are capable of being acted upon by a gaseous feeder medium, lending a forward motion in a rotational direction to the rope, and which are located entirely inside the treatment tank;    devices for causing a treatment agent to act on the rope in the treatment tank; and    steering and guiding devices for the rope in the treatment tank, by which the rotating endless rope is guided over a rotational path located in the treatment tank and including the feed nozzle means and the J-box;    wherein the feed nozzle means are movably supported in the treatment tank, and associated with them are adjusting means by which a motion causing the rope, emerging from their rope outlet, to be laid in place can be imparted upon entry into the downstream J-box.

       10 . The apparatus as defined by  claim 8  wherein the blower has a suction stub, discharging into the treatment tank, and a compression stub, coaxial to the suction stub, that communicates with the feed nozzle means.  
   
   
       11 . The apparatus as defined by  claim 10 , wherein the suction stub and/or the compression stub is pivotably supported relative to the treatment tank.  
   
   
       12 . The apparatus as defined by  claim 6  wherein each of the feed nozzle means has a feeding segment for the rope, which segment ends in the rope outlet and is movable jointly with the feed nozzle means.  
   
   
       13 . The apparatus as defined by  claim 7  wherein the adjusting device has a pivoting device, which is coupled to the feed nozzle means and by which the feed nozzle means are pivotable about the vertical axis.  
   
   
       14 . The apparatus as defined by  claim 12 , wherein the feeding segment has an outlet part, having the rope outlet, which is supported on the feed nozzle means displaceably in the passage direction of the rope through the feed nozzle means.  
   
   
       15 . The apparatus as defined by  claim 14 , wherein the outlet part is coupled to an adjusting device of the adjusting means that imparts a reciprocating axial motion to the outlet part.  
   
   
       16 . The apparatus as defined by  claim 13  wherein the pivoting device and the adjusting device are coupled to one another by a control unit, by which the pivoting device and the adjusting device are triggerable jointly or separately to generate a motion of the rope outlet.  
   
   
       17 . The apparatus as defined by  claim 6  wherein it has filter means, located in the treatment tank, which are connected upstream of the suction stub of the blower.  
   
   
       18 . The apparatus as defined by  claim 17 , wherein the filter means are located in the treatment tank removably through at least one opening in the treatment tank.  
   
   
       19 . The apparatus as defined by  claim 6  wherein deflection means that deflect the rope are located in the region between the rope inlet and the J-box.
