Definitions
- the present invention relates to a method for reducing edge waves in a sheet formation system of a Fourdrinier paper or Fourdrinier cardboard machine in the area of the task of a substance suspension jet supplied by a headbox onto a rotating sieve. It also relates to a sheet formation system, particularly suitable for carrying out the method, of a Fourdrinier paper or Fourdrinier cardboard machine with a headbox, a revolving screen onto which a stock suspension jet supplied by the headbox is applied, and a respective jet boundary on the two screen sides.
- an edge wave can occur, which adversely affects the sheet formation.
- the formation of such an edge wave in an exemplary sheet formation system of a Fourdrinier paper or Fourdrinier cardboard machine is explained in more detail with reference to FIGS. 1 to 3 of the accompanying drawing.
- FIG. 1 shows a sectional partial view of the exemplary sheet formation system 8 of a Fourdrinier paper or Fourdrinier cardboard machine with a headbox 1, which supplies a free-flowing material suspension 2 which strikes a rotating sieve 3 in the area of a beam impact point 4.
- the free jet 2 formed by the headbox 1 becomes on the screen 3 in the area of the jet impact point 4 deflected at an angle ⁇ less than 10 ° in the direction MD. This deflection creates a pressure field 5 which has a length F1.
- the jet impact point 4 on the screen 3 is provided at a distance A in the lower lip 6 of the headbox 1, which distance is measured in the direction MD.
- the dimension or length F1 of the printing field 5 measured in the direction MD runs, for example, from 1 to 1.5 times the beam thickness S1. Due to the backflow, the pressure field 5 begins in the free jet 2 against the direction of flow at a distance F2 from the jet impact point 4, which can be approximately 0.1 to 0.3 times the jet thickness S1.
- the material suspension free jet 2 experiences a kink in the area of the jet impact point 4.

- level E2 there is a pressure curve in between.
- FIG. 2 also shows one of two lateral beam edge boundaries EM of the sheet formation system 8.
- a different flow process in the transverse direction CD to the outside begins, which is based on the Sieve 3 facing the underside of the beam occurs increasingly.
- This flow process comes to a halt in and after the pressure field 5 at a respective lateral beam edge boundary EM of the exemplary sheet formation system 8, as a result of which a pressure surge forms and a flow deflection takes place in the z direction upwards.
- This hydraulic mechanism creates a line-up of the jet edge and an edge wave R.
- the flow can be given space, so that the pressure pulse and the relevant deflection preferably take place in the wire belt running direction MD and less in the z direction.
- the edge wave R can be minimized.
