Combing means for a comb of a combing machine

Abstract

Toothed clothing for a comb of a combing machine as well a process for producing same is described. The toothed clothing includes a plurality of adjacently arranged teeth, which form at least one teeth row orientated transversely to the working direction. The teeth of the clothing are formed from the solid and are made in one piece to form a tooth bar. In addition, a top comb and a circular comb for a combing machine having such toothed clothings are also described. The toothed clothings hereby include one or more teeth rows.

       11 . A process according to  claim 10 , wherein as a semi-finished product for the tooth bar a drawn profile is used as the solid, on which the teeth of the toothed clothing are subsequently formed.  
   
   
       12 . A process according to  claim 10  wherein, as seen transversely to the working direction of the teeth, the outer contour of the teeth of a teeth row is formed from the solid.  
   
   
       13 . A process according to  claim 11 , wherein, as seen transversely to the working direction of the teeth, the outer contour of the teeth are formed at least partly by a drawn profile of the tooth bar.  
   
   
       14 . A process according to  claim 11 , wherein the teeth of a teeth row are formed by the shaping of grooves extending in the working direction of the tooth bar.  
   
   
       15 . A process according to  claim 14 , wherein the teeth are shaped at least partly by grinding.  
   
   
       16 . A process according to  claim 14 , wherein the teeth are shaped at least partly by eroding.  
   
   
       17 . A process for producing a toothed clothing according to  claim 5 , wherein a plurality of rows of teeth are shaped on the circumference of a hollow cylinder, which are parallel to its middle axis, and further wherein the hollow cylinder is subsequently divided into a plurality of segments.  
   
   
       18 . A top comb for a combing machine having a toothed clothing, which includes a plurality of adjacently arranged teeth, wherein the teeth form at least one teeth row orientated transversely to a working direction, wherein the teeth row with its teeth is operatively configured as a tooth bar made in one piece, and that a dimension (K) of the teeth row—as seen transversely to the working direction of the teeth—corresponds approximately to a working width (G) of the top comb.  
   
   
       19 . A top comb for a combing machine comprising: 
 a toothed clothing, which comprises a number of adjacently arranged teeth, wherein the teeth form at least one teeth row orientated transversely to a working direction; and    wherein a number of adjacently arranged teeth of the teeth row is operatively configured as a tooth bar made in one piece, wherein a dimension (K) of the tooth bar—as seen transversely to the working direction of the teeth—is less than a working width (G) of the top comb, and further wherein a number of tooth bars are arranged over the working width of the top comb.    
   
   
       20 . A top comb according to  claim 18 , wherein the top comb comprises a base body, to which at least one tooth bar is attached by a fixing mechanism.  
   
   
       21 . A top comb according to  claim 19 , wherein the top comb comprises a base body, to which at least one tooth bar is attached by a fixing mechanism  
   
   
       22 . A top comb according to  claim 20 , wherein the base body, is die-cast to at least one tooth bar in the form of a die-cast part or an injection-molded part.
