  • Such a pressing device is known from WO-A-92/17641.
  • the first press roll is as so-called deflection adjustment roller, i.e. the The roller has a stationary support body or a yoke which is rotatably mounted on a roll shell, which is hydraulically open the yoke is supported, even at extremely high Press forces in operation a practically deflection-free Behavior of the roll shell or, if desired, a set certain deflection of the roll shell, wherein the yoke can bend.
  • the second press roll is in the known arrangement as a so-called shoe press roll formed, which in turn has a stationary support body, over which a tubular press jacket rotates.
  • this press jacket runs over a press shoe, the shape of the counter roll, i.e. the first press roll, the is designed as a deflection adjusting roller, is adapted, so that an extremely high pressing force in the area of Press nip can be generated and at the same time gradual increase in the pressure when entering the Press nip is made possible.
  • the invention is therefore based on the object, pressing devices of the type mentioned at the outset, that the maximum bending load that the tensile elements during operation may be reduced.
  • the second press roll is not used as a deflection roll trained, but (e.g. with a smaller machine width) is designed as a quasi-bending-free solid roller, strong Bending moments can be exerted on the tension elements, if the definition of the second press roll on the first press roll only done via the tension elements. Because they are attachments directly attached to the bearing blocks of the second press roller, e.g. e.g. Scraper, felt guide rollers or the like, so would this in the case of conventional arrangements for an additional bending load of the tension elements. Such attachments need on the one hand a floating bearing to accommodate changes in length Operation to compensate for the second press roller.
  • This length compensation is more or less fraught with friction and generates tilting moments around the center during compensatory movements the pivot bearing.
  • Can in the axial direction of the second press roll these tilting moments are not caused by the flexible tension elements are recorded and thus lead to conventional arrangements to uncontrolled inclinations of the pedestals and thus excessive bending stress on the tension elements.
  • the bending load is also strong in this case reduced, namely by means are provided to the on absorb the second bearing blocks exerted tilting moments.
  • the bearing blocks are determined immediately on the rotatable bearing pin, since the bearing pin at the relative low deflection of the solid roller only a slight one Experience passion.
  • the pivot bearings are due to the high of the trunnions absorbed forces and due to the large inclination of the Bearing pins are preferably designed as self-aligning bearings that do not Can transmit tilting moments, i.e. tilting of the pedestals allow.
  • an additional Support a tilt-free support of the bearing blocks in with respect to the rotatable roller jacket, provided the second Press roll is designed as a deflection roll.
  • the second press roll is designed as a solid roll, so is a position fixation by means of the additional support bearings the bearing blocks on the rotating bearing journals of the solid roller reached.
  • the pivot bearings itself be designed as a bearing, the tilting moments be able to record.
  • the pivot bearing as double-row tapered roller bearings in an O arrangement, so that the pedestals immediately without additional support bearings on the roller shell or on the bearing journal of the solid roller in its Angular position can be fixed.
  • This version has the advantage that an additional support bearing can be dispensed with.
  • the second bearing blocks can be connected to a cross member be connected to each other so that a tilt is excluded.
  • additional devices such as with belts, brackets, guides and the like, the bearing blocks in their position relative to the frame fix in order to avoid tilting of the pedestals.
  • Handlebars on the foundation or on the frame can be tilted of the second pedestals and thus an excessive bending load avoid the tension elements.
  • a handlebar provided with a first end rigidly attached to one of the second pedestals is and with a second end on a fixed guide which attacks the second end against displacements in the axial direction secures but shifts in the vertical direction allows, with the second bearing blocks on a horizontal Connection element are coupled together.
  • the handlebars can also be used on the first Bearings can be guided. Such an embodiment is preferred if the first press roll immediately (without ball bushings) is mounted on the first pedestals.

  • one of the second Bearing blocks via a fixed in the axial direction of the press rolls, however, articulated connection movable in the longitudinal direction of the tension elements coupled to the first bracket.
  • a particularly simple version for the articulated connection arises if this comprises a pin which within a Guide is held displaceably in the vertical direction.
  • This measure has the advantage that the articulation at a change of one belonging to one of the two press rolls Press jacket or when changing one passed through the press nip endless felt ribbon is not in the way.
  • Figures 1 and 2 is a pressing device according to the invention designated overall by the number 10.
  • the press device 10 comprises a first press roll 14, which as So-called shoe press roll with a hydraulically pressed Press shoe 11 is formed, and one above the first Press roll 14 arranged second, parallel to this press roll 16, which is designed as a so-called deflection adjustment roller.
  • the structure of a deflection adjustment roller and a shoe press roller is generally known, for which purpose, for example US-A-5,338,279 and to which DE 92 03 395 U1 is referred to the disclosure of which is hereby incorporated by reference.

  • the second press roller 16 is formed as a deflection adjusting roller the bearing pins 55 bend under load, while the roller jacket 58 is hydraulically supported on the yoke 15, is largely free of deflection or a desired one (low) deflection. So the ends come up of the roller tube 58 under load significantly less oblique than the second bearing pin 55. Since each of the collar 56 on the Bushing 57 when the yoke 15 bends considerable frictional forces are transferred to the second bearing blocks 20, 21, would without the tilting training of the pivot bearings tilt the second bearing blocks 20, 21 with the bearing journal 55 since the tensile elements which are flexible in the axial direction of the press roll 16 26 can not absorb these frictional forces, which leads to a strong bending stress of the tension elements 26 would result.
  • the second drive side is also Bearing block 20 via a sliding joint 32 with the first drive-side bearing block 18 connected.
