Definitions
- Press roll having a rotating or rotating press cover and a counter roll, wherein the fibrous web is dewatered in an extended press nip between the counter roll and the press cover of the press roll.
- the invention also relates to a method for treating a fibrous web which is carried out with the device according to the invention.
- the rotating press cover not only fulfills its function as a pressing element, but also serves as a means for further transport of the fibrous web after mechanical dewatering.
- a transfer fabric which is performed in some embodiments in addition to the felt through the extended press nip, is therefore superfluous.
- the aim of the invention is also to disclose a rotating press cover, with which a reliable further transport of the fibrous web can be carried out after the press nip.
- the polymer layer may also comprise a particulate filler having a different hardness than the polymer layer, such as kaolin clay, a polymer material or metal, preferably stainless steel.
- a particulate filler having a different hardness than the polymer layer, such as kaolin clay, a polymer material or metal, preferably stainless steel.
- Fiber web is passed from the press cover to a transfer element, is guided, wherein a press cover with the properties according to the
- the press cover 25 transfers the fibrous web 9 to a transfer element 31.
- the transfer element 31 is a transfer cover 27.
- the transfer element can also be a roller which takes over the fibrous web 9 from the press cover 25. This roller can also be drained.
- the conditioning of the transfer fabric 27 should be such that there is no or only a very small moistening of the transfer fabric
- the conditioning can be carried out for example with compressed air or a compressed air sword.
- Fiber web transported 9, is continuously sucked.
- Fiber web 9 can be used.
- the fibrous web 9 can be removed from the press cover 25, for example, be scraped, and a
- FIG. 2 A comparison with FIG. 2 shows that the press felt 14c is no longer needed in the board machine according to the invention.
- a precisely defined press profile can act on the fibrous web 9.
- a press profile of a long-nip press unit 29 is shown in FIG. 6 as a curve 37.
- Curve 38 shows a press profile of a press unit with standard rollers without extended press nip 26.
- the adjustable felt guide 40 also allows adjustment of the contact surface or the contact length between felt 33 and fibrous web 9 after the extended press nip 26.
- a steam blower box (not shown) be provided to heat the fibrous web 9 before the extended press nip 26.
- the smallest possible pressing pressure on the fibrous web 9 should preferably act on entry of the fibrous web 9 into the extended press nip 26.

Abstract
L'invention concerne un dispositif et un procédé de traitement d'une bande continue de matière fibreuse (9) dans une machine à papier ou à carton, dans un ensemble de presse à longue zone de pression (29), comprenant un rouleau de pression (24) présentant un revêtement de pression rotatif (25), et un contre-rouleau (23), la bande de matière fibreuse (9) étant débarrassée de l'eau qu'elle contient, dans une zone prolongée de pression (26) entre le contre-rouleau (23) et le revêtement de pression (25) du rouleau de pression (24). L'invention est caractérisée en ce que la bande continue de matière fibreuse (9) est guidée, après avoir quitté la zone prolongée de pression (26), sur un revêtement de pression rotatif spécial (25) du rouleau de pression (24), vers une zone de transfert (30), dans laquelle la bande continue de matière fibreuse (9) est transférée du revêtement de pression (25) sur un élément de transfert (31, 27).
