Zusammenfassung:	A paper machine headbox vane has a vane component ( 2 ) and a pivot member ( 3 ) connected together with anchoring elements ( 4 ), which pass through holes ( 5, 6 a, 6 b) provided in both components ( 2, 3 ). The vane ( 1 ) is fastened to a headbox engagement groove in the headbox by the pivot member ( 3 ) which has two or more pivot member elements ( 3 a1 , 3 a2 , 3 a3) which have positioning holes for positioning the vane component ( 2 ) and the pivot member elements ( 3 a1 , 3 a2 , 3 a3) in relation to each other. A least one longitudinal hole in each element allows its free linear movement in relation to the vane component ( 2 ). The vane component ( 2 ) has a longitudinal opening ( 7 ), which receives the pivot member ( 3 ) with an opening between two successive pivot member elements ( 3 a1 , 3 a2 , 3 a3). The vane component ( 2 ) and the pivot member elements ( 3 a1 , 3 a2 , 3 a3) can be of different materials.
