Apparatus for manufacturing a honeycomb structure having slits

Abstract

An apparatus for manufacturing a honeycomb structure having slits and a plurality of arrays of numerous cells aligned in parallel, wherein the slits communicate with external space and are formed along the cell arrays. The apparatus includes an extruder having an extruding die for a honeycomb structure, and a slit forming member arranged near the extruding die and protruding along arrays of a molded article being extruded in which slits are to be formed.

What is claimed is:  
     
         1 . An apparatus for manufacturing a honeycomb structure having slits and a plurality of arrays of numerous cells aligned in parallel; the slits communicating with external space and being formed along the cell arrays, which comprises: 
 an extruder having an extruding die for a honeycomb structure; and    a slit forming member arranged near said extruding die and protruding along arrays of a molded article being extruded in which slits are to be formed.    
     
     
         2 . The apparatus for manufacturing a honeycomb structure having slits according to  claim 1 , 
 wherein the slit forming member is arranged so as to protrude inwardly toward the extruding die.    
     
     
         3 . The apparatus for manufacturing a honeycomb structure having slits according to  claim 1 , 
 wherein said slit forming member is arranged so as to protrude slit forming member outwardly toward the extruding die.    
     
     
         4 . The apparatus for manufacturing a honeycomb structure having slits according to  claim 3 , 
 wherein said slit forming member is a J-shaped bit.    
     
     
         5 . The manufacturing apparatus for a honeycomb structure having slits according to  claim 1 , further comprising: 
 monitoring means for monitoring a position of the molded article being extruded; and    control means for controlling actions of the slit forming member.    
     
     
         6 . The manufacturing apparatus for a honeycomb structure having slits according to  claim 2 , further comprising: 
 monitoring means for monitoring a position of the molded article being extruded; and    control means for controlling actions of the slit forming member.    
     
     
         7 . The manufacturing apparatus for a honeycomb structure having slits according to  claim 3 , further comprising: 
 monitoring means for monitoring a position of the molded article being extruded; and    control means for controlling actions of the slit forming member.    
     
     
         8 . The manufacturing apparatus for a honeycomb structure having slits according to  claim 4 , further comprising: 
 monitoring means for monitoring a position of the molded article being extruded; and    control means for controlling actions of the slit forming member.
