Description

technical field

[0001] The invention relates to a structural element for a functional part in a headbox and a headbox comprising the functional part. The invention also relates to a structural element for a headbox and a method for producing the structural element. Background technique

[0002] As is known in the art, in a paper machine or other type of web making machine, stock or fiber suspensions are usually fed from a stock header or stock headers directly or through separate The pipes are supplied to the headbox, and the plurality of individual pipes guide the flow of fiber stock and are connected with the upstream end of the headbox. The slurry is then discharged as a spray from the slice chamber of the headbox through slice lip openings on the forming wire, the slice lip openings being located at the downstream end of the headbox, to form a web on the wire.

[0003] A paper machine can produce a single-ply paper or board web comprising only one type of cellulosic fi...
