  • the shoe presses of the type mentioned are flexible Roll shell usually through the concave bent inwards Press shoe pressed against a rigid counter roll. Between Press roll and counter roll creates a press nip, which has a certain length in the direction of feed of the material to be pressed, so-called press zone length. The longer this press zone is, the larger the at the same contact pressure of the Press shoe placed on the material to be pressed. The contact pressure the press shoe can over in the feed direction the press zone can also be different, i.e. a gradient exhibit.
  • the press zone is extended, so the press shoe into consideration.
  • these are with the Lengths of approx. 300 mm reached today limits, because the immersion depth of the flexible roll shell due to the replica of the counter roll concave support surface of the press shoe accordingly increased.
  • Such a strong immersion of the flexible Roller shell has the disadvantage of a strong one Curvature of the roll shell in the inlet and outlet area of the Press opening.
  • the deformations are particularly strong and critical in the area of the two edges of the press shoe, since here also in the axial direction a transition to the radial one Support of the roller jacket due to circular cylinder shape he follows.
  • the invention has for its object a shoe press of the type mentioned in such a way that this Disadvantages do not occur.
  • the deformation of the roll shell in the area of the two axial edges of the Press shoe can be reduced.
  • rollers are each a shoe with a flat support surface have, the support surfaces of the two shoes to each other are essentially parallel and one between them Form press nip, and that at least one support device radially flexible, in particular elastic is.
  • the radially flexible support devices are given one additionally leadership. It also becomes a three-dimensional one Deformation of the roller shell of the pressure roller in the area avoided between the press shoe and the roll jacket support, because by rolling off the flexible support devices the support devices are on the shoe of the counter roller deformed in the same way as the roll shell in the area of the shoe of the pressure roller.
  • the counter roller can use rigid supports for your roll shell be provided without excessive deformation of the roll shell occurs.
  • both have Roll each a radially flexible support device for an axial end portion of their roll shell, wherein these support devices on opposite to each other axial ends of the two rollers and one axial End region of the shoe opposite the other roller are provided and are supported on this.
  • the each other supports of the two rollers can be used as rigid tension discs be formed. Also due to this asymmetrical
  • the jacket support becomes a very small roll jacket deformation achieved, however, both rollers essentially are constructed identically and have the same width can. In addition, the width of the press nip is larger here.
  • rollers there are two Rollers, each having a radially flexible support device for both axial end areas of the roll shell have, the support devices each in pairs are arranged opposite each other.
  • the support devices roll with each other in this embodiment and thus also guarantee a low level Mantle deformation.
  • the two rollers are in the trained essentially the same.
  • a radially flexible support device is preferably one Rim provided with a particularly air-filled tube. This is structurally inexpensive and enables one Adjustment of the radial flexibility of the support device by changing the pressure in the hose.
  • the Rim brackets can be provided.
  • Variable diameter of the rim are preferred for this Elements of the rim can be moved radially. By change of the rim diameter can be the contact pressure of the hose on the counter roller and thereby flexibility and deformation of the roll shell can be adjusted.
  • an additional Sealing hose may be provided.
  • roller jacket and hose are preferably form-fitting connected to each other, the hose in particular its support side with circumferentially extending Grooves is provided, in which corresponding elevations intervene on the inside of the roller shell.
  • the invention can be inflexible support devices eccentric clamping washers provided and a shoe asymmetrical in at least one roller be arranged.
  • the two rollers preferably essentially the same diameter as one another on.
  • the shoe press shown in FIGS. 1 and 2 comprises a first press roll 1 with a stationary support 2 circumferential flexible roll shell 3 and at least one largely flat support surface 4 for the inside 5 of the Roll shell 3 having the first shoe 6.
  • the first shoe 6 of the roller 1 acts with a second, likewise one at least largely flat support surface 7 shoe 8 together, the one rotating around a stationary carrier 9 flexible roll shell 10 of a second roll 11 supports.
  • the support surfaces 4 and 7 of the two shoes 6 and 8 run essentially parallel to one another, preferably with a low average convergence in Running direction of the roll shell 3.
  • the side shields 12, 13 of the two rollers as a rim 14, 15 with air-filled Hose 16, 17 formed.
  • the rim 14, 15 is there rotatably supported on the stationary carrier 2, 9 while the hose 16, 17 is firmly connected to the roll shell 3, 10, in particular is glued. In this way, one radial support of the axial end areas of the roller shells 3, 10 achieved with radial compliance.
  • the two rollers 1 and 11th essentially with respect to that between the rollers 1, 11 formed press nip 20 formed symmetrically to each other. That is, the two roller shells 3, 10 face each other same width and the flexible side plates 12, 13 are arranged opposite each other in pairs.
  • the shoes 6, 8 of both rollers have the same Width and also essentially the same length on.
  • the two shoes 6 and 8 of the two rollers 1 and 11 are each with respect to the assigned stationary carrier 2 or 9 radially adjustable, as indicated by arrows 18 and 19 is. Only roller 1 is preferred Equipped for pressure control, while the Roller 11 only with means to compensate for deflection of the stationary support 9 by radial adjustment of the Shoe 8 is equipped.
  • the roller 1 is therefore self-stressing Press roll formed while the roller 11 does this serves as a counter roll, the shoe 8 at least on one Place radially rigidly connected to the stationary support 9 is, but preferably at two adjacent to the ends of the shoe 8 Put.
  • Press nip 20 By the formed between the two rollers 1 and 11 Press nip 20 is in the illustrated embodiment a paper web 21 and on the roller 1 facing On the side of the paper web 21, a felt belt 22 is guided. in principle can also on the opposite side of the Paper web 21 a felt belt through the press nip 20 become.
  • the invention are the rollers 1, 10 and in particular the Shoes 6, 8 basically designed in the same way as in the first variant shown in FIGS. 1 and 2.
  • the shoes 6, 8 also have a flat, mutually parallel support surface 4 and 7 on.
  • the in 3 shown variant of the invention only the roller 1 with radially flexible side plates 12, 13 in the form of with air-filled tubes 16, 17 provided rims 14, 15 trained while the second roller 11 rigid side shields 112, 113.
  • both the width of the roll shell 10 and the width of the shoe 8 of the second Roller 11 larger than the respective width in the first Roller 1.
  • the width of the roll shell 3 corresponds to the first roller 1 substantially the width of the shoe 8 the second roller 11 so that the two flexible side shields 12, 13 of the first roller 1 the two axial end regions of the shoe 8 of the second roller 11 arranged opposite are.
  • the hoses 16, 17 of the first roller 1 on the shoe 8 of the second roller 11 at Operation of the shoe press can be unrolled.
  • this is the Deformation of the roll shell 3 in the area of the shoes 6, 8 corresponding deformation of the axial end regions of the roll shell 3 by pressing the flexible side plates 12, 13 of the first roller 1 to the shoe 8 of the second roller 11. It is also ensured here that the roller shell 3 between shoe 6 and the two side plates 12, 13 practical no three-dimensional bending deformation is experienced. Due to the larger width of the second roller 11 is here despite the use of rigid side shields 112, 113 excessive bending deformation between the shoe 8 and the two side plates 112, 113 also avoided.
  • both rollers 1, 11 are each with a radially flexible side plate 12 and a radial rigid side plate 113 equipped, but to each other opposite axial ends of the rollers 1, 11 are provided are.
