Abstract
A vane is mounted to a turbulence generator in a headbox by a mounting arrangement that includes an assembly bar that is rigidly connected to an anchoring element of the turbulence generator. The anchoring element has an engagement groove of dovetail shape that receives a similarly shaped protrusion on the assembly bar to rigidly mount the assembly bar to the anchoring element. The assembly bar also includes a continuous journaling groove configured to receive a pivot member of the vane to fix the vane to the assembly bar while leaving the vane free to pivot about a pivot axis that extends in the cross-machine direction.
