  • Patent number: 6736938
    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.

  • Patent number: 6030500
    Abstract: An arrangement for feeding stock to a headbox in a papermaking machine which comprises at least one stock header with an inlet for receiving stock into the header and a plurality of stock header outlets permitting stock to leave the header. For each stock header outlet there is a stock conduit downstream of the stock header outlet permitting stock to pass from the stock header outlet, through the conduit to the inlet of the headbox. The arrangement includes a dilution header for feeding a diluent such as water to a plurality of stock conduits. The dilution header has an inlet for receiving a diluent not the dilution header and a plurality of outlets permitting the diluent to leave the dilution header. For each dilution header outlet, there is a diluent conduit permitting the passage of a diluent from the dilution header into a stock conduit.
