Definitions

  • the invention relates to a pressing device for treatment a fibrous web, especially for drainage, Smoothing or calibration of a paper web in one Paper machine, with a shoe press roll and one with this shoe press roll forming a press nip counter roll.
  • shoe press rolls In the treatment of fibrous webs, in particular in the dewatering of paper webs, shoe press rolls are used which cooperate with a counter roll to form a press nip, the counter roll also being able to consist of a shoe press roll.
  • the development trend is to increase the length of the shoes, with a high press pulse with the lowest possible pressure gradients and the lowest possible maximum pressure being achieved in the press nip .
  • the object of the invention is to provide a pressing device at the beginning specified type so that even at substantially flat press nip the high demands on drainage, Smoothing and calibration, especially at high ones Speeds, taken into account and the required Drive power can be introduced.
  • the width of the drive belt preferably corresponds to essentially the width of the fibrous web, and it can be considered waterproof tape, as particular reinforced plastic tape or as a metal tape be trained. It is also possible to use the drive belt to train as a water-absorbing tape and a Press felt web to use.
  • the press nip is preferably of two shoe presses formed wide nip press nip and runs in essentially flat, the length of the pressing surface in the area from about 250 to 600 mm.
  • FIG. 1 shows a press device consisting of two shoe press rolls exists, each a press shoe 1 or 3 and an elastic, circumferential cylindrical roller shell 2 or 4 include.
  • the press shoes 1, 3 are via suitable pressurization devices pressable against each other and lay between them a press nip 7 fixed due to the design of the press shoes 1, 3 is designed as a flat nip.
  • a press nip 7 is a press felt web 6 and a fibrous web during operation or paper web 5 out.
  • the press zone length in Flat nip press nip 7 is preferably in the range of about 250 up to about 600 mm, which makes it possible for gentle treatment with little compaction of the surface layers perform the fibrous web and with a high press pulse work at low pressure gradients.
  • the pressing device is driven in the illustrated embodiment solely through the press felt web 6 leading to this Purpose via at least one not shown in the drawing Felt drive roller is guided, with a Wrap angle in the range of about 200 ° to 270 °, see above that taking into account a between press felt web 7 and Driving roller effective friction ⁇ in the range of 0.2 to 0.4 the required high drive power introduced can be.
  • the press felt web 6 is for this purpose as a web with high Strength and low elongation to absorb felt tension trained up to at least 15 kN / m and can be integrated with Reinforcing elements may be provided.
  • a minor one Elongation is desirable insofar as one is wrapped around one Drive roller the belt does not experience excessive slip and Slip friction occurs instead of static friction.
  • Figure 2 shows a schematic representation of a first variant an advantageous drive unit, a first Guide roller 8 and a second guide roller 9 are used by which either the guide roller 8 or larger diameter both guide rollers 8, 9 can be driven.
  • the relative arrangement of the two guide rollers 8, 9 is preferably chosen so that the distance a between the two guide rollers 8, 9th is smaller than the diameter of the smaller guide roller 9. This results in advantageous looping conditions.
  • FIG 3 shows a schematic representation of another advantageous Variant of a drive unit in which a first Guide roller 8 arranged in a fixed bearing unit 10 and this first guide roller 8 is assigned a second guide roller 9 which is held in a pivot bearing 11, so that the two guide rollers 8, 9 drive one of them can be or both can be driven due to the belt tension are automatically pressed against each other.
  • the two Guide rollers move due to the wrapping the drive belt 6 in opposite directions.
