  • Turbulence generator in the headbox of a papermaking machine
    Patent number: 5110416
    Abstract: A turbulence generator (20) in the headbox of a paper making machine which produces internal microturbulence in the pulp suspension flow (F), whereby the homogeneity of the flow is improved. The turbulence generator (20) comprises a system of turbulence tubes, which consists of a number of turbulence tubes (22) placed one above the other and side by side. These tubes start at the inlet side of the turbulence generator (20) having thereat a substantially circular cross-section, being gradually and smoothly, in the flow direction, converted to a rectangular cell structure with planar sides. The cell structure (30) at the outlet side (23) of the turbulence generator (20) consists of an overlapping cell system, wherein there are at least two inclined middle cell rows (31, 32; 31a, 31b, 32a, 32b) placed one above the other, in which cell rows the cells have rectangular cross-sections. The cells have a shorter planar side (X) and a longer planar side (Y).
