         7 . The device according to  claim 6 , wherein the plurality of adjusting slats is divided into a first set and a second set, wherein the first set serves as a stop for the first outer wall and the second set serves as a stop for the second outer wall. 
     
     
         8 . The device according to  claim 7 , wherein the adjusting slats in the first and second sets of adjusting slats touch each other, and at least one adjusting slat of the first set touches the first inner wall and at least one adjusting slat of the second set touches said second inner wall. 
     
     
         9 . The device according to  claim 8 , wherein the adjusting slats of the first and second sets of adjusting slats that are located between the the adjusting slats of the first and second sets of adjusting slats that serve as a stop for the corresponding outer wall, and the adjusting slat which touches the corresponding inner wall, form a whole. 
     
     
         10 . The device according to  claim 6 , wherein the first mold half is not moveable relative to the holder and wherein the first outer wall always touches said first inner wall. 
     
     
         11 . The device according to  claim 10 , wherein at least some adjusting slats of the plurality of adjusting slats touch each other and an adjusting slat of the plurality of adjusting slats touches said second inner wall, whereby the adjusting slats between the adjusting slat which serves as a stop for the second outer wall and the adjusting slat which touches the second wall form a whole. 
     
     
         12 . The device of  claim 1 , wherein the holder is a block having at least one a recess in the longitudinal direction provided to receive the plurality of adjusting slats. 
     
     
         13 . The device further comprising displacement means for moving the first mold half relative to the second mold half.
