Shunt for a web divided into several sectional webs

Abstract

A shunt for a web, in particular a web of corrugated board, which is to be divided into several sectional webs in the conveying direction, comprises several shunting elements which are disposed side by side below the web of corrugated board and which are individually movable at least into a top position and a bottom position. Several compressed-air nozzles are provided, which are disposed above the shunting elements and directed towards the shunting elements and which are individually actuated by compressed air.

1 . A shunt ( 6 ) for a web ( 2 ) of corrugated board, which is to be divided into several sectional webs ( 2   a ,  2   b ,  2   c ,  2   d ) in the conveying direction ( 1 ), comprising 
 a plurality of shunting elements ( 13 ), 
 which are disposed side by side below the web ( 2 ) of corrugated board, and  
 which are individually movable at least into a top position and a bottom position;  
   an adjusting drive ( 15 ) which acts on each shunting element ( 13 ), moving each shunting element ( 13 ) between the positions; and    several compressed-air nozzles ( 16 ) which are disposed above the shunting elements ( 13 ) and directed towards the shunting elements ( 13 ), 
 the nozzles ( 16 ) being individually actuatable by compressed air.  
   
   
   
       2 . A shunt ( 6 ) according to  claim 1 , wherein the compressed-air nozzles ( 16 ) are individually actuatable by compressed air from a valve unit ( 19 ) which is triggered by a control unit ( 22 ).  
   
   
       3 . A shunt ( 6 ) according to  claim 1 , wherein at least one compressed-air nozzle ( 16 ) is disposed above each shunting element ( 13 ).  
   
   
       4 . A shunt ( 6 ) according to  claim 1 , wherein each compressed-air nozzle ( 16 ) is disposed centrally above a shunting element ( 13 ).  
   
   
       5 . A shunt ( 6 ) according to  claim 1 , wherein each compressed-air nozzle ( 16 ) is disposed closely above a shunting element ( 13 ) in the top position thereof.
