Definitions
- the invention relates to a machine for producing and / or dimming a Fibrous web with a press section for dewatering this, an upstream Shaper for sheet formation and a downstream drying section for drying the Fibrous web.
- the disadvantage here is the large space requirement and the relatively high production cost for the two extended press nips, which involve the participation of relatively expensive shoe press rolls be formed.
- the object of the invention is therefore to provide a paper machine with a small, yet efficient and with as little effort as possible To create press section.
- the object was achieved in that the press section from only a press nip formed by two press rolls, through which in addition to the Fibrous web, arranged on both sides thereof, at least one press felt is guided, the fibrous web in the former to a dry content of at least 18%, preferably at least 20% is dewatered, the first dry group of the Dryer section consists of a maximum of 3 heated drying cylinders, which of the The fibrous web is partially wrapped and the fibrous web from the former to at least one roller or one at the end of the first drying group Belt in the form of a forming wire, a press felt, a transfer belt or one Dryer screen is supported.
- the dry content of at least 18%, preferably at least 20% after Shaper allows the restriction to only one extended nip in the Press section. Because of the relatively high moisture content of the fibrous web after the press nip is a closed guide of the fibrous web from the former especially up to the end of the first drying group, especially in high Machine speeds are important. In addition, extensions of the Fibrous web also due to the high moisture content at the beginning of the dryer section be balanced as quickly as possible, which is why at least the first drying group is as short as possible. Otherwise there would be a risk of web breaks or Wrinkling. A compensation of the stretching is generally achieved in that the following dryer group is operated at a higher speed than the previous one.
- the length of the press nip should be greater than 300 mm, preferably greater than 500 mm.
- the web speed should not exceed 1500 m / min to ensure a sufficient pressing time.
- the line force in the press nip should be above 800 KN / m, preferably above 1000 KN / m and in particular above 1200 KN / m. This enables pressing impulses of more than 60 KPa s to be achieved.
- At least one suction device should be in the former before the transfer point of the fibrous web on the press section at least one suction device can be arranged, which by the forming wire sucks the water out of the fibrous web.
- the fibrous web to the press section together with at least the fibrous web an endlessly circulating, water-absorbent and / or water-permeable Band is passed through a pre-press nip preferably formed by two rollers.
- the forming wire should be as water-permeable tape wrapping around the vacuumed roller.
- To take up the water squeezed out in the pre-press nip should also at least one roller in the form of a press roller from a water-absorbent Be wrapped in a band in the form of a press felt.
- a moistening device should be in the press section in front of the press nip preferably in the form of a steam box to influence the Moisture cross profile of the fibrous web be present. So that comparative effect of several press nips within the press section not only achieved, but also surpassed.
- at least in the Press section or a subsequent unit sensors for detecting the Moisture cross profile of the fibrous web can be arranged, which at least on the Act on the humidifier. The results of these sensors can also be used Control of the suction device and / or the pressing forces in the pre-press nip in the former to be used. However, this presupposes that at least the However, the moistening device preferably also the suction device and / or the Pressing forces across the fiber web can be controlled separately in zones.
- the The fibrous web leaves the press nip horizontally or inclined downwards and at least over the upper press felt a gutter to catch the from the upper Press roller centrifuged water can be arranged.
- At least the first drying group should be very short, preferably from at most 2, in particular from at most one heated Drying cylinder can be designed.
- FIG. 1 shows a schematic section of a paper machine for producing a wood-free paper web with a finished basis weight between 50 and 100 g / m 2 .
- the fibrous web 1 is one water-permeable forming screen 10 supported to the transfer point to the press section 4 guided.
- the fibrous web 1 is at a dry content of at least 20% drained.
- the fibrous web 1 together with the forming wire 10 and a water-absorbent press felt 19 by a pre-press nip formed by a vacuumed roll 17 and a press roll 18 16 out.
- each press roll 5 of an endless revolving press felt 6.7 is wrapped.
- the fibrous web 1 from Forming wire 10 passed to the upper press felt 6, what from a suction guide roller 22 of the upper press felt 6 is supported.
- the lower press felt 7 via a moistening device 13 led in the form of a steam blow box, the water vapor to influence the Moisture cross profile of the fibrous web 1 is used.
- the first drying group 8 consists only of a heated drying cylinder 9, which the fibrous web 1 is guided, the fibrous web 1 from the dryer fabric 11 this drying group 8 is pressed against the drying cylinder 9.
- the fibrous web 1 is always one Roller or a belt supported so that the fibrous web 1 runs safely is guaranteed at high speeds.
- the generally endless ones Belts are guided over normal 23 or suction guide rollers 22.
- the fibrous web 1 is together with the Dryer screen 11 of the respective dryer group alternately in an analogous manner Drying cylinder 9 and suction guide rollers 22 out.
- the nip itself is a cylindrical lower press roll 5 and one upper shoe press roll 5, wherein the shoe press roll 5 from a flexible press jacket, which he uses a pressure shoe with concave Contact surface is guided. This allows the formation of long press nips with over 300 mm length.
- the line force in the press nip is over 1000 KN / m and Web speed at 1200 m / min.
