Definitions

  • the invention relates to a press jacket for a press device for treatment a material web such as a paper or cardboard web in particular in a press nip, provided in the outer surface Grooves and / or blind holes.
  • Such press sleeves are used, for example, for press devices, in which a flexible around a rigid support Press jacket is pressed against a particularly rigid counter surface.
  • a web of material in particular can be a paper or cardboard web. Because of the flexibility of the press jacket can in particular also in an extended nip press can be used as the jacket of a shoe press unit.
  • press sleeves are partially grooved or blind holes with which an additional while water storage volume that is as constant as possible during the running time should.
  • the groove width is usually in a range from 0.5 to 1.5 mm, the preferred groove width being 1.0 mm.
  • the depth of the parallel Side walls of such grooves are usually in one area from 0.5 to 2.0 mm, the preferred depth being 1.0 mm. Partially the grooves are also conical at an angle of 5 to 15 °.
  • Such a press jacket is known for example from US-A 5 543 015.
  • the blind holes usually have a diameter in Range from 1.6 to 2.8 mm, with the preferred diameter being 2.2 mm is.
  • Such blind holes usually have a depth in the area 1.5 to 2.5 mm, with the preferred depth being 2.0 mm.
  • these blind holes are usually cylindrical.
  • the aim of the invention is to provide a press jacket of the type mentioned create the despite the relatively high press loads and despite the Flow properties of the elastomer materials commonly used ensures the maintenance of the largest possible storage volume.
  • the press jacket Has grooves and / or blind holes
  • the side walls in the opening area are provided with a chamfer and / or one accordingly have a curve section running round section to one at To counteract the pressure reduction occurring volume reduction.
  • Edge length of the chamfer preferably about 1 to 3 times and preferably about 2 times that in the longitudinal direction transverse to the machine direction measured edge length.
  • the length of the edge measured in the longitudinal direction the chamfer can in particular be in a range from approximately 0.1 mm to 0.3 mm and are preferably about 0.2 mm.
  • Corresponding dimensions are preferably also appropriate for one provided a curve section rounding section. In this case, these dimensions are preferably one on the rounding section applied tangent.
  • the in Direction of groove or hole depth preferably with respect to one the edge length of the tangent applied to the rounding section Rounding section about 1 to 3 times and preferably 2 times that measured in the longitudinal direction, preferably with respect to the tangent Edge length.
  • the edge length measured at the rounding section of the rounding section in a range from about 0.1 mm to about 0.3 mm and preferably be about 0.2 mm.
  • the edge length measured in the direction of the groove or hole depth the chamfer or the rounding section can in particular also be dimensioned in this way be that between the bottom of a respective groove or blind hole and the chamfer or the rounded section is cylindrical Wall section remains.
  • the rounding section can run along a curve line, which is at least essentially, for example, an arc or a Evolvent corresponds.
  • the chamfer or the rounding section is immediate formed on the outer edge of a respective groove or blind bore.
  • the side wall of a respective blind bore is preferably with a ring-like chamfer extending over their entire inner circumference or rounding section.
  • FIG. 1 to 4 is a schematic, sectioned partial view each shown a press jacket 10 for a press device for treatment a material web can be used in a press nip.
  • a material web can in particular be a paper or cardboard web act.
  • a plurality of grooves 14 is in each case in the outer lateral surface 12 and / or blind bores 16 are provided.
  • the side walls 18 of these grooves 14 are each provided with a chamfer 20, in order to counteract a reduction in volume that occurs under pressure.
  • each also a rounding section running according to a curve line 20 ' may be provided.
  • Such rounding sections 20 ' are in the figures 1 and 2 shown in dashed lines.
  • the edge length y measured in the direction of the groove or hole depth (cf. FIGS. 1 to 3) of a respective chamfer 20 amounts to those shown Embodiments about 1 to 3 times and preferably about twice the length x measured in the longitudinal direction (cf. Figures 1 to 3).
  • the chamfer is expediently in a range of approximately 0.1 mm to about 0.3 mm, preferably about 0.2 mm.
  • the rounding sections 20 ' which are optionally provided instead of the chamfers 20 can advantageously have comparable edge lengths x and y, preferably with respect to each other Rounding section 20 'applied tangent measured in the Plane of the respectively replaced chamfer 20 can run (see FIGS. 1 and 2).
  • FIGS. 1 to 4 of a press jacket 10 is in the direction of the groove or hole depth measured edge length y (see FIGS. 1 to 3) of a respective chamfer 20 or a respective rounding section 20 'such that between the bottom 22 of a respective groove 14 or a respective blind bore 16 and the chamfer 20 or the rounding section 20 'a cylindrical Wall section 24 remains.
  • the Chamfer 20 or the rounded sections 20 ' directly at the opening area delimiting outer edge of the relevant groove 14 (see FIG 1) or blind bore 16 (see FIG. 2).
  • the edge length y measured in the direction of the groove or hole depth a respective chamfer 20 or a respective rounding section 20 ' greater than the depth of the cylindrical adjoining the bottom 22 Wall section 24.
  • the bottom 22 is the bottom Groove 14 is partially circular in cross section.
  • each of the two is in the circumferential direction of the press shell extending side walls 18 of the respective groove 14 each provided with a chamfer 20 or a rounded section 20 '.
  • this is in the direction of FIG Groove or hole depth measured edge length y of the chamfer 20 both larger than the distance a of this chamfer from the outer edge as well as larger than the depth of that provided between the bottom 22 and the chamfer 20 cylindrical wall section 24.
