Method and device for cleaning the removal zone on a carder/carding machine

Abstract

The present invention relates to a method or device for removing dust, waste and short fibres in the removal zone of a carder or carding machine, having a stripper roller or doffer, a doffing cylinder, an upper and a lower press roller, and a transverse conveyor belt. A solution according to the present invention provides at least one of the following means: means, for example a compressed air device, for generating a preset air flow in the region between the stripper roller, the doffing cylinders and the press rollers; an exhaust device for the area of the lower stripper and the lower press roller; an exhaust device for the area above the upper mote knife.

         5 . The device as claimed in any one of the foregoing claims, characterised in that the generated air current is continuously produced.  
     
     
         6 . The device as claimed in any one of the foregoing claims, characterised in that an interval sequence, defined by a duration and the frequency of the generated air current, can be set.  
     
     
         7 . The device as claimed in any one of the foregoing claims, characterised in that the generated air current lasts up to 5 seconds, in any case up to 15 seconds, or up to 60 seconds.  
     
     
         8 . The device as claimed in  claim 10  characterised in that the air current can be generated in intervals of 1 to 60 minutes, or 3 to 30 minutes.  
     
     
         9 . The device as claimed in any one of the foregoing claims, characterised in that the interval sequence can be controlled.  
     
     
         10 . The device as claimed in any one of the foregoing claims, characterised in that it forms a component of the web baffle plate or the web baffle bridge.  
     
     
         11 . The device as claimed in any one of the foregoing claims, characterised in that a waste baffle plate is arranged below the gap through which the dirt is blown.  
     
     
         12 . The device as claimed in any one of the foregoing claims, characterised in that an exhaust device is arranged below the gap through which the dirt is blown.  
     
     
         13 . The device for removing dust, waste and short fibres in the removal zone of a carder or carding machine, having a stripper roller or doffer, a doffing cylinder and an upper and a lower press roller, characterised in that a lower exhaust device is provided for the region of the lower stripper and the lower press roller.  
     
     
         14 . The device as claimed in any one of the foregoing claims, characterised in that the lower exhaust device comprises the entire working width of the carder.  
     
     
         15 . The device as claimed in any one of the foregoing claims, characterised in that the lower exhaust device comprises only a part of the working width of the carder, under the region where the sliver spout is located.  
     
     
         16 . The device for removing dust, waste and short fibres in the removal zone of a carder or carding machine, having a stripper roller or doffer, a doffing cylinder and an upper and a lower press roller, characterised in that an upper exhaust device is provided for the region above the upper mote knife and upper press roller.  
     
     
         17 . The device as claimed in any one of the foregoing claims, characterised in that the upper exhaust device is arranged over the entire working width of the carder.  
     
     
         18 . The device as claimed in any one of the foregoing claims, characterised in that the upper exhaust device is arranged over that part of the working width of the carder where the sliver spout is located.  
     
     
         19 . The device as claimed in any one of the foregoing claims, characterised in that the upper exhaust device is integrated in the cap.  
     
     
         20 . A method for removing dust, waste and short fibres in the removal zone of a carder or carding machine, having a stripper roller or doffer, a doffing cylinder and an upper and a lower press roller, characterised in that particles such as dust, dirt or short fibres accumulated by a preset air flow can be blown away in the region between the stripper roller, the doffing cylinder and the press roller.  
     
     
         21 .
