Forming shoulder of a tubular bag packaging machine

Abstract

The present invention relates to a forming shoulder of a tubular bag forming, filling and sealing machine, wherein the forming shoulder ( 2 ) is produced from a porous material and is divided into individual segments ( 3 ). (FIG. 1 )

1 . A forming shoulder of a tubular bag forming, filling and sealing machine, characterized in that the forming shoulder ( 2 ) is produced from a porous material and is divided into individual segments ( 3 ). 
     
     
         2 . The forming shoulder according to  claim 1 , characterized in that said forming shoulder is produced by a sintering process. 
     
     
         3 . The forming shoulder according to  claim 1 , characterized in that said forming shoulder is produced by a generative process. 
     
     
         4 . The forming shoulder according to  claim 1 , wherein the forming shoulder is configured such that gas can be selectively applied via a gas supply to individual segments ( 3 ) or gas can be selectively suctioned from individual segments ( 3 ) in order to form an air cushion or a vacuum which is effective on the surface of the segment ( 3 ). 
     
     
         5 . The forming shoulder according to  claim 1 , characterized in that individual segments ( 3 ) are in each case provided with at least one pressure sensor for measuring a ram pressure or for measuring a flow resistance. 
     
     
         6 . The forming shoulder according to  claim 1 , characterized in that said forming shoulder has a porous surface layer. 
     
     
         7 . The forming shoulder according to  claim 1 , characterized in that the entire material of the forming shoulder ( 2 ) is porous. 
     
     
         8 . The forming shoulder according to  claim 1 , characterized in that at least individual segments of the segments ( 3 ) are linear. 
     
     
         9 . The forming shoulder according to  claim 1 , characterized by a measuring and control unit which is operatively connected to sensors that are associated with the individual segments ( 3 ). 
     
     
         10 . The forming shoulder according to  claim 5 , characterized in that individual segments ( 3 ) are in each case provided with at least one pressure sensor for measuring a ram pressure or for measuring a flow resistance. 
     
     
         11 . The forming shoulder according to  claim 10 , characterized in that said forming shoulder has a porous surface layer. 
     
     
         12 . The forming shoulder according to  claim 10 , characterized in that the entire material of the forming shoulder ( 2 ) is porous. 
     
     
         13 . The forming shoulder according to  claim 10 , characterized by a measuring and control unit which is operatively connected to the sensors that are associated with the individual segments ( 3 ). 
     
     
         14 . The forming shoulder according to  claim 1 , characterized in that at least individual segments of the segments ( 3 ) are circular.
