Machine for the continuous treatment of fabric

Abstract

The machine comprises an inlet basin ( 1 ) for the fabric (T); an outlet basin ( 3 ) for the fabric; between the inlet basin and the outlet basin a fabric treatment path with pneumatic transportation with alternate motion of the fabric. The treatment path comprises at least two side by side conduits ( 15, 17, 19, 21, 23, 25 ), between which at least one intermediate basin ( 5, 7, 9, 11, 13 ) is positioned for collecting the fabric.

         4 . A machine according one or more of the preceding claims, characterized in that said inlet basin ( 1 ) and said outlet basin ( 3 ) have a bottom with a depressed central area and lateral sides inclined in an upwards direction.  
     
     
         5 . A machine according to one or more of the preceding claims, characterized in that said conduits have a cross-section in a shape that is adapted to working with fabric in rope form.  
     
     
         6 . A machine according to  claim 5 , characterized in that said conduits have an approximately circular cross-section.  
     
     
         7 . A machine according to one or more of the preceding claims, characterized in that each conduit includes two Venturi tubes positioned in opposite directions to perform the pneumatic transportation of the fabric in the two directions alternatively; motion reversing means being provided for activating alternatively one or the other of said Venturi tubes.  
     
     
         8 . A machine according to one or more of the preceding claims, characterized in that an impact wall ( 35 ,  37 ) is positioned in front of each end of said conduits, against which the fabric is flung during treatment.  
     
     
         9 . A machine according to one or more of the preceding claims, characterized in that associated with each end of said conduits a member ( 39 ,  41 ) is provided for raising the fabric from the basin towards the respective conduit.  
     
     
         10 . A machine according to  claim 9 , characterized in that said raising member includes a motorized reel.  
     
     
         11 . A machine according to one or more of the preceding claims, characterized in that said inlet basin, said outlet basin and said at least one intermediate basin are constituted by a partition of a common basin.  
     
     
         12 . A machine according to one or more of  claims 1  to  10 , characterized in that said inlet basin, said outlet basin and said at least one intermediate basin are separate from each other.  
     
     
         13 . A machine according to  claim 12 , characterized in that said at least one intermediate basin oscillates independently of the adjacent basins.  
     
     
         14 . A machine according to one or more of the preceding claims, characterized in that it includes measuring members to detect the quantity of fabric in each basin, associated with intercepting elements to close off the drawing air through the relative conduits and intercepting the transport of the fabric in the conduits according to the quantity of accumulated fabric detected.  
     
     
         15 . A machine according to  claim 14 , characterized in that the quantity of fabric is measured by the weight of the fabric in the basin.  
     
     
         16 . A machine according to  claim 14  or  15 , characterized in that there are two of said measuring members, in order to measure the quantity of fabric accumulated at each of the two ends of the respective basin.
