摘要

Turbulence device with flaps for the lip channel in the headbox of a paper machine. The device contains one or more disk-like turbulence flaps 30 whose input edges are fixed in the direction of flow F in conjunction with the support structure of the turbulence generator 20 of the headbox or the like. The turbulence flaps 30 are free at their output edge and extend in the cross direction over the entire width of the headbox. Holes 33a and recesses 33b, 33c that extend inward from the smooth surface 32 are present in the disk-like turbulence flaps 30a, 30b, 30c, with which the holes and/or recesses turbulence formed in the pulp suspension stream running past the flaps is made more effective.
