Abstract (en)
[origin: WO2012085343A1] The invention relates to a flow pipe for the turbulence generator (14) of the headbox (10) of a fiber web machine, which flow pipe (17, 17') has two ends, an inlet end (13) and an outlet end (15), and between which ends (13, 15) there is a flow channel (16). At least one groove (24) and at least one protrusion (25) is arranged on the external surface (21.1 - 21.4) of the flow pipe (17), in order to attach the flow pipe (17) to adjacent flow pipes (17'). In addition, the invention also relates to a turbulence generator for the headbox of a fiber web machine.
