Definitions

  • the present invention relates to a press jacket flexible material for a pressing device for drainage a material web in a press nip, the Press jacket transverse to the web running direction over a press area, which corresponds to the width of the press nip, and per se edge areas adjoining both sides of the pressing area extends and on its outside with recesses for Water absorption is provided.
  • Such a press jacket is from DE 44 01 580 A1 known.
  • the press jacket described in this document is along its entire width in the direction of web travel extended grooves for water absorption. additionally can be provided further grooves or holes that should increase the elasticity of the press cover, but not are trained to absorb water.
  • the provided over the entire width of the press jacket Water grooves have the disadvantage that over time Damage, particularly in the form of cracks, because the press jacket is weakened in the area of the grooves.
  • the invention has for its object a press jacket of the type mentioned in such a way that the danger damage to the press casing, in particular belt formation, is reduced without dewatering performance the press jacket is reduced.
  • the recesses in the two outer areas of the press cover can preferably be designed as blind holes, for example circular, polygonal or oval Can have cross-section.
  • the grooves in the inner area of the press jacket can either be straight in the direction of web travel run, or for example wavy or be zigzag-shaped.
  • the total opening area of the wells per unit area of the press jacket is in the inner area and in both outer Areas of the press jacket preferably substantially the same.
  • the total storage volume of the wells is also pro Area unit of the press jacket in the inner area and two outer areas of the press shell preferably in essentially the same. Deviations can occur in both cases be of the order of ⁇ 10%. hereby there will be even drainage throughout Width of the web guaranteed.
  • the invention is preferred for a press jacket for a Shoe press applicable, but can also be used for example a press jacket of a rigid roller can be used.
  • the press jacket 1 shown in Fig. 1 extends transversely to Web running direction I over a press area P, which by the Width of a press shoe 2 acting on the press jacket 1 is specified, and adjoining on both sides Edge areas R. To the two sides, the press jacket 1, as shown, tapered in a known manner his.
  • the press jacket 1 On the side facing away from the press shoe 2 is the press jacket 1 provided with depressions 3 and 4, which the recording of Water from one through the nip of the whole here guided web of material, not shown, serve in particular paper web.
  • the press jacket 1 in the embodiment of 1 is formed as a circular blind holes 3 in cross section, while in the inner space remaining in between B the depressions of the press jacket 1 as in the direction of web travel I extending straight grooves 4 are formed.
  • the number and cross section of the holes 3 and the grooves 4 is chosen so that the total opening cross section of the wells 3 and 4 of the press jacket 1 in areas A and B. per unit area of the roll shell 1 essentially is the same size, so that a sufficient drainage performance is given over the entire pressing range P. Should a different drainage performance over the pressing area P may be desired, so the number and the total opening cross section of wells 3 and 4 of course be varied accordingly. The same applies to the total storage volume of wells 3 and 4.
  • Fig. 2 of an inventive Press cover 1 essentially agrees with the variant of Fig. 1 match.
  • the left half of Fig. 2 are in the outer area A rectangular cross-section depressions 3 and in the inner region B in the web running direction I zigzag extending grooves 4 shown.
  • the right Half of FIG. 2 are depressions 3 in the outer region A. with an oval cross-section and wavy in the inner area B. Grooves 4 shown.
  • the different forms of the wells 3 and 4 can be combined in any way , that is, not all in FIG. 2 Variations shown for a single press jacket 1 be provided.
  • the length is limited by the Wells 3 in the two outer areas A cracking by spreading in the area of the wells Damage caused by the load on the press jacket when Operation of the pressing device prevented.
  • I continuous grooves 4 in the inner area B of the press jacket 1 is also a good drainage performance of the press jacket 1 ensured.
