Combing device for a circular comb and method for the manufacture of the combing device

Abstract

Embodiments of the invention relate to a combing device for a combing machine exhibiting at least a circular comb and at least a top comb, with a number of comb teeth serving to engage in a fiber fleece and arranged side by side in a direction approximately vertical to the direction of combing, with the combing device exhibiting at least one comb element with at least two, three, or more comb teeth made in one piece and arranged side by side in the direction extending vertically to the direction of combing.

1 . A Combing device for a combing machine exhibiting at least one circular comb and at least one top comb, the combing device comprising:
 at least one comb element with at least two, three, or more comb teeth made in one piece, serving to engage in a fiber fleece, and arranged side by side in a direction extending vertically to a direction of combing.   
   
   
       2 . The Combing device of  claim 1 , wherein at least one of the comb teeth has a saw tooth shaped design with two tooth flanks extending parallel to the direction of combing and a tooth face connecting the tooth flanks and extending vertically thereto. 
   
   
       3 . The Combing device of  claim 1 , wherein the at least one comb element exhibits at least one fastening area made in one piece with the comb teeth and designed for the attachment of the at least one comb element to the combing machine. 
   
   
       4 . The Combing device of  claim 1 , wherein the at least one comb element has at least two, three, or more additional comb teeth arranged in series in the direction of combing. 
   
   
       5 . The Combing device of  claim 1 , wherein tips of the comb teeth, arranged side by side in the direction extending vertically to the direction of combing, are arranged on a straight line extending vertically to the direction of combing. 
   
   
       6 . The Combing device of  claim 4 , wherein tips of the additional comb teeth arranged in series in the direction of combing are arranged approximately on a circular arc. 
   
   
       7 . The Combing device of  claim 1 , wherein the at least one comb element is made at least in part from high-alloyed, stainless steel. 
   
   
       8 . The Combing device of  claim 7 , wherein the high-alloyed, stainless steel is chrome nickel steel. 
   
   
       9 . The Combing device of  claim 1 , wherein the combing device belongs to a top comb. 
   
   
       10 . The combing device of  claim 1 , wherein the combing device belongs to a circular comb. 
   
   
       11 . A Method comprising:
 forming, from a cuboid-shaped raw material block, slots in the raw material block, with the slots separating individual comb teeth from each other in a direction extending vertically to a direction of combing; and   removing the comb teeth from the raw material block in an aspect vertical to the direction of combing, with a connecting area connecting the comb teeth with each other in the direction extending vertically to the direction of combing.   
   
   
       12 . The method of  claim 11 , further comprising preserving a fastening area of the raw material block. 
   
   
       13 . The method of  claim 11 , wherein said forming comprises forming two, three, or more slots simultaneously. 
   
   
       14 . The method of  claim 11 , wherein said forming and/or said removing are performed using spark erosion machining or spark erosion depth machining. 
   
   
       15 . The method of  claim 11 , wherein said removing further comprises processing, from two opposite directions, the raw material block, respectively extending vertically to the direction of combing.
