Abstract

In a heddle frame with an upper ( 10 ) and with a lower frame part ( 11 ) and with heddle bars ( 17, 18 ) attached to the frame parts, it is provided that the frame parts ( 10 ) are provided with a profiled rib ( 24 ) running in the longitudinal direction, and that the heddle bars ( 17 ) have a profiled longitudinal groove ( 25 ) gripping around the profiled rib.

1 . Heddle frame comprising at least one frame part extending in a longitudinal direction, and including at least one heddle bar attached to the frame part, said frame part being is provided with a profiled rib running in the longitudinal direction, and wherein the heddle bar comprises a profiled longitudinal groove engaging the profiled rib.  
   
   
       2 . Heddle frame according to  claim 1 , wherein the profiled rib of the frame part and the profiled longitudinal groove of the heddle bar form a positive connection transverse to the longitudinal direction.  
   
   
       3 . Heddle frame according to  claim 1 , wherein the profiled rib of the frame part forms a snap-in connection with the profiled longitudinal groove of the heddle bar.  
   
   
       4 . Heddle frame according to  claim 1 , wherein the profiled longitudinal groove is undercut and the profiled rib has a cross-section adapted thereto.  
   
   
       5 . Heddle frame according to  claim 4 , wherein connection between profiled rib and profiled longitudinal groove is configured in dovetail form.  
   
   
       6 . Heddle frame according to  claim 1 , wherein the frame part is an extruded section.  
   
   
       7 . Heddle frame according to  claim 1 , wherein the heddle bar ( 17 ,  18 ) is an extruded section of steel.  
   
   
       8 . Heddle frame according to  claim 7 , wherein the extruded section is post-treated by cold-rolling.  
   
   
       9 . Heddle frame according to  claim 7 , wherein the section of the heddle bar is provided with ribs on both sides of a substantially rectangular longitudinal groove.  
   
   
       10 . Heddle frame according to  claim 9 , wherein one of the ribs has a smaller cross-section than the other rib.  
   
   
       11 . Heddle frame according to  claim 1 , wherein the profiled rib of the frame part is affixed to the longitudinal groove of the heddle bar.  
   
   
       12 . Heddle frame according to  claim 1 , wherein the frame part comprises a first material and the heddle bar attached thereto comprises a second material.  
   
   
       13 . Heddle frame according to  claim 1 , comprising an upper frame part and a lower frame part to which the heddle bar is attached.
