ABSTRACT:
A wet end of a paper-making machine, including a headbox with a chamber and a discharge nozzle. A turbulence generator is connected with the headbox and includes a plurality of fluid passages disposed substantially parallel to each other. Each fluid passage is in fluid communication with the headbox chamber and has an inlet. All of the inlets conjunctively define a fluid inlet area. A fiber stock delivery device includes at least one outlet, with all of the outlets conjunctively defining a fluid discharge area. Each outlet is configured to discharge the fiber stock in a direction substantially parallel to the fluid passages in the turbulence generator. The fluid discharge area of the fiber stock delivery device is smaller than the fluid inlet area of the turbulence generator. A hydraulic increaser interconnects the fluid discharge area of the fiber stock delivery device with the fluid inlet area of the turbulence generator. The hydraulic increaser includes at least two interior abutting surfaces, with each abutting surface having at least one end defining an adjoining edge with another said abutting surface. Each abutting surface defines a line at each end which is disposed tangent to the abutting surface at the respective end. Each tangent line defines an acute angle with a tangent line of an adjacent abutting surface which is between approximately 1.degree. and 10.degree. preferably not greater than approximately 4.degree..
