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.
