Definitions
- Patent classes D21F 1/02, 04, 06, 08 listed and known only the difference to this invention, which corresponds to the current state of the art, is the simpler construction and the modular construction.
- this invention can serve for all types of web-shaped carriers or for the refinement of such products.
- Cloth casseroles are used to manufacture or refine web-shaped products such as paper, cardboard, tissue, nonwoven or nonwoven; in addition, they are used for finishing only for fabric and film webs.
- the task of the headbox is to distribute a mass which is uniform over the web width and web direction or over time and which, in the dried or hardened state, imparts certain technological or chemical properties to the product.
- the quality of the product produced or finished with the headbox is measured in the
- Sample size, sampling, measurement errors, ie the statistical treatment of the production goods, have a decisive influence on the numerical values of the above-mentioned quality features.
- the quality data have unlimited sample size no deviation or with a very small sample a large deviation.
- the quality data are to be defined accordingly and thus the requirements for the respective headbox which influences the deviations in the characteristics are to be defined.
- headboxes With the interface on the pipeline, headboxes currently consist of a constant part:
- Turbulence generators e.g. Tube bundle or perforated plate
- the aim of this invention is to
- the headbox basically consists of:
- a central distributor (1) made of flexible plastic pipes (2) r the inside is smooth, but otherwise are freely movable.
- Control valves (3) are installed in these lines and can be operated both by hand and by hydraulic or electrical controls.
- ER S The substance distribution modules (4), in which a turbulence generator (5) is integrated, connect to the control valves.
- An adjusting device (6) is located after the turbulence generator.
- Sheets 1 and 5 of the drawings show the sketch of a system described above, here for a fourdrinier screen, consisting of a distributor (1), connected to it 4 modules (4) of a headbox with a total width of 2000 mm, the headbox nozzle without a partition the overall width is sufficient.
- module 1 is switched off, for example, by moving the adjustment device (6) in the nozzle, the web width can be reduced by .500 mm.
- Sheet 2 of the drawings shows the sketch of a device similar to sheet 1, but the distributor (1) is arranged here to the side of the system.
- Sheet 3 of the drawings shows the sketch of a device similar to sheet 1, the distributor (1) here, however, being led out obliquely to the side of similarly known constructions.
- the connecting elements between the distributor and the headbox also consist of flexible lines (2).
- Sheet 4 of the drawings shows the sketch of the system described at the beginning for an inclined screen. Two of these headboxes are arranged here with a barrier water chamber in between.
