Abstract

The present invention discloses a device ( 100 ) for abrading or removing material from a joint or groove by means of at least one abrasive area ( 30 ) provided at a rib ( 20 ) associated with a main body ( 10 ).

1 . Device for abrading or removing material from a joint or groove by means of at least one abrasive area provided at a rib associated with a main body. 
     
     
         2 . Device according to  claim 1  wherein the main body is embodied as a wedge or a three-dimensional trapezium. 
     
     
         3 . Device according to  claim 1  wherein the main body comprises
 at least one air chamber in its inner part or 
 at least one indentation on its outside. 
 
     
     
         4 . Device according to  claim 1  wherein the abrasive area's side averted from the joint or groove is melted into the rib. 
     
     
         5 . Device according to  claim 1  wherein the abrasive area's side averted from the joint or groove is glued at the rib. 
     
     
         6 . Device according to  claim 1  wherein the abrasive area is embodied as a substrate at least sectionally or at least partially provided with abrasive material. 
     
     
         7 . Device according to  claim 6  wherein the abrasive material comprises bort or ceramic splinters. 
     
     
         8 . Device according to  claim 6  wherein the abrasive material is isle- or field-wise arranged on the abrasive area and the abraded or removed material is dispatchable between the respective isles or fields. 
     
     
         9 . Device according to  claim 6  wherein the substrate comprises a tissue carrier tape. 
     
     
         10 . Device according to  claim 1  wherein the rib is insertable into a recess of the main body and fixable in the recess. 
     
     
         11 . Device according to  claim 10  wherein the rib is essentially T-shaped and the rib's region averted from the abrasive area is form-fittingly receivable in the recess. 
     
     
         12 . Device according to  claim 1  wherein the rib's side averted from the abrasive area comprises at its one end at least one snap-in nose. 
     
     
         13 . Device according to  claim 12  wherein the at least one snap-in nose is arranged at the rib's front end in terms of the working direction. 
     
     
         14 . Device according to  claim 12  wherein the rib's section comprising the at least one snap-in nose is elastically supported in relation to the rest of the rib. 
     
     
         15 . Device according to  claim 10  wherein the snap-in nose
 is engageable into a notch provided in the recess when the rib is inserted in the recess and 
 is disengageable from the notch by pressing a region at the end of the rib in order that the rib can be pulled out of the recess. 
 
     
     
         16 . Device according to  claim 15  wherein the region protrudes beyond the main body at the rib's front end in terms of the working direction when the rib is inserted in the recess. 
     
     
         17 . Device according to  claim 12  wherein the snap-in nose
 is engageable into a notch provided in the recess when the rib is inserted in the recess and 
 is disengageable from the notch by pressing a region at the end of the rib in order that the rib can be pulled out of the recess. 
 
     
     
         18 . Device according to  claim 17  wherein the region protrudes beyond the main body at the rib's front end in terms of the working direction when the rib is inserted in the recess. 
     
     
         19 . Device according to  claim 1  wherein the rib's region facing the abrasive area comprises a protrusion at one of its two ends or at both ends opposite the main body. 
     
     
         20 . Device according to  claim 1  wherein the rib's region facing the abrasive area is slanted or angled or bent or curved at one of its two ends or at both ends.
