Fourdrinier section of a web production machine, for paper or cardboard or tissue, has a rotating roller with outer studs and inner eccentric drives to oscillate the fourdrinier in different directions on the web plane
The machine for the production of a fiber web (8), of paper or cardboard or tissue, has at least one fourdrinier (7) with a mechanism to oscillate the fourdrinier in different directions on the web plane. The fourdrinier is oscillated by the projecting studs (6) at least at one rotating roller (1), fitted with eccentric drives (4,5) within it, with rotating out-of-balance weight masses (11-14) to give fourdrinier oscillations at 0.25-1000.0 Hz and preferably 1-100 Hz.
