Definitions

  • the invention relates to a press cover according to the preamble of claim 1.
  • Such jackets are used for pressing devices in which a rotating around a rigid support flexible press jacket is pressed against a particular rigid counter surface.
  • a web is guided, which may be in particular a paper or board web. Due to the flexibility of the press jacket this can be used in a long nip press as a jacket of a Schuhpreßtechnik.
  • the groove width is usually in a range of 0.5 to 1.5 mm, with the preferred groove width being 1.0 mm.
  • the depth of the parallel side walls of such grooves is usually in a range of 0.5 to 2.0 mm, the preferred depth being 1.0 mm.
  • Some of the grooves are also conical at an angle of 5 to 15 °.
  • Such a press cover is for example from the US Pat. No. 5,543,015 known.
  • the blind bores usually have a diameter in the range of 1.6 to 2.8 mm, the preferred diameter being 2.2 mm.
  • Such blind bores typically have a depth in the range of 1.5 to 2.5 mm, with the preferred depth being 2.0 mm.
  • These blind holes are usually cylindrical.
  • a press roll of a roll press is off EP 0 241 389 A1 known.
  • the aim of the invention is to provide a press cover of the type mentioned, which ensures the maintenance of the largest possible storage volume despite the relatively high pressing loads and despite the flow properties of the elastomeric materials überally used.
  • a volume reduction occurring at a respective press load is counteracted by providing a chamfer or a rounding section corresponding to a curved line in the critical opening region of a respective groove, which completely or at least partially compensates for the "depression" of the grooves.
  • the purpose specified in the claims form and design of the grooves is based on the new state of a respective press jacket.
  • the edge length of the chamfer measured in the direction of the groove depth is preferably approximately 1 to 3 times and preferably approximately 2 times the edge length measured in the longitudinal direction transversely to the machine direction.
  • the edge length of the chamfer measured in the longitudinal direction may, in particular, be in a range of approximately 0.1 mm to 0.3 mm and preferably approximately 0.2 mm.
  • Corresponding dimensions are also provided in a corresponding to a curved line extending rounding section. In this case, these dimensions are related to a tangent applied to the rounding section.
  • the edge length of the rounding portion measured in the direction of the groove depth, preferably with respect to a tangent to the rounding portion is about 1-3 times, and preferably twice, the edge length measured longitudinally, preferably with respect to the tangent .
  • the edge length of the rounding portion measured longitudinally, preferably with respect to the tangent applied to the rounding portion may be in a range of about 0.1 mm to about 0.3 mm, and preferably about 0.2 mm.
  • the edge length of the chamfer or of the rounding section measured in the direction of the groove depth can in particular also be dimensioned such that a cylindrical wall section remains between the bottom of a respective groove and the chamfer or the rounding section.
  • the rounding section can run in accordance with a curved line, which at least essentially corresponds, for example, to a circular arc or an involute.
  • press cover according to the invention is Chamfer or the rounding section formed directly on the outer edge of a respective groove.
  • the chamfer or the rounding section can be offset inwardly with respect to the outer edge of a respective groove in the direction of the groove depth and be formed at a distance therefrom.
  • At least the side walls of the groove extending in the circumferential direction of the press jacket are preferably each provided with a chamfer or a rounding section.
  • FIGS. 1 to 4 is shown in a schematic, sectioned partial representation in each case a press jacket 10, which is suitable for a pressing device for the treatment of a material web in a press nip.
  • the material web may in particular be a paper or board web.
  • the press coats after the Fig. 2 and 4 are merely illustrative and are not covered by the claims.
  • a rounding section 20 'extending in accordance with a curved line can also be provided in each case.
  • the edge length y measured in the direction of the groove or bore depth (cf. FIGS. 1 to 3 ) of a respective chamfer 20 in the illustrated exemplary embodiments is approximately 1 to 3 times and preferably approximately 2 times the edge length x measured in the longitudinal direction (compare FIGS FIGS. 1 to 3 ).
  • the longitudinally measured edge length x of a respective chamfer is suitably in a range of about 0.1 mm to about 0.3 mm, wherein it is preferably about 0.2 mm.
  • the rounding sections 20 ' which may alternatively be provided instead of the chamfers 20, expediently have comparable edge lengths x and y, these preferably being measured with respect to a tangent applied to the respective rounding section 20', which is in the plane of the respectively replaced chamfer 20 can run (see the Figures 1 and 2 ).
  • a respective chamfer 20 or a respective rounding section 20 ' is dimensioned such that a cylindrical wall section 24 remains between the bottom 22 of a respective groove 14 or a respective blind bore 16 and the chamfer 20 or the rounding section 20'.
  • the chamfers 20 and the Rundungsabête 20 ' directly on the opening region limiting outer edge of the respective groove 14 (see. FIG. 1 ) or blind bore 16 (see. FIG. 2 ) educated.
  • the present case in the direction of the groove or. Hole depth measured edge length y of a respective chamfer 20 and a respective rounding portion 20 'slightly larger than the depth of the adjoining the bottom 22 cylindrical wall portion 24th
  • the bottom 22 of the groove 14 is formed partially circular in cross section.
  • each of the two extending in the circumferential direction of the press jacket side walls 18 of the respective groove 14 is provided in each case with a chamfer 20 and a rounding portion 20 '.
  • the side wall 18 is provided with a extending over the entire inner circumference ring-like chamfer 20 and rounding portion 20 '.
  • the edge length y of the chamfer 20 measured in the direction of the groove or bore depth is both greater than the distance a of this chamfer from the outer edge and greater than the depth of the cylindrical wall section 24 provided between the base 22 and the chamfer 20 ,
