ABSTRACT:
Fastening of a profile bar to adjustment spindles at a discharge opening of a head box of a paper machine. A series of fastening holes or recesses are made into one edge of the profile bar and provided with chamferings. In the end of the adjustment spindles situated next to the discharge opening, a recess is provided with a series of screws being fitted in one side thereof. These screws are provided with ends coresponding to the chamferings in the fastening holes of the profile bar. A second set of screws coaxial with the first set of screws are provided in an outer wall of the recess, with inner ends of the second set of screws being provided with parts corresponding to the outer chamferings of the fastening holes in the profile bar. The inside or first set of screws can be locked in a position such that, when the profile bar is attached into connection with the inside screws by the holes and the chamferings thereof, a center plane of the profile bar coincides with an axial center plane of the adjustment spindles. The profile bar can be locked into position by the outside or second set of screws.
