Definitions

  • the invention relates to a seal for delimiting two pressure areas different internal pressure inside a perforated, rotatable Roll shell, the pressure ranges from the roll shell and one to Roller jacket towards the open pressure box are limited, the seal between Pressure box and roller jacket available and at least one printing area with one Overpressure or vacuum source is connected.
  • the object of the invention is therefore to provide a seal with reduced wear to develop.
  • the object was achieved in that the seal from at least one, cylindrical, rotatably mounted in a seal holder Sealing element is formed, the axis of rotation of which is parallel to the axis of rotation of the Roll shell runs.
  • the rotatable arrangement of the sealing element reduces the friction between the sealing element and the inside of the roll shell significantly.
  • the rotating roll shell offset by contact, d. H. Friction the sealing element in rotation around its axis of rotation, so that no or at least one strong reduced relative movement between the roll shell and the cylindrical Sealing element occurs.
  • the seal is formed by only one or more cylindrical sealing elements becomes. These can be one behind the other and / or parallel to the direction of rotation Axis of rotation can be arranged side by side.
  • the adaptation and the sealing effect can be significantly improved if that Sealing element is pressed against the inside of the roll shell.
  • a sealing element made of metal, in particular made of hard metal and / or of a plastic, preferably an elastic Plastic and / or ceramic.
  • the outer surface of the sealing element can be smooth or profiled, preferably in Circumferential direction or axially grooved or a polygonal cross section have.
  • a fluid such as water, compressed air or the like is particularly suitable for this. etc. ..
  • a particularly simple construction results when the sealing element in one Seal holder of the pressure box is rotatably fixed.
  • This seal is because of the cylindrical shape and the rotation of the Sealing element less susceptible to contamination than standing sealing strips.
  • the suction roll has two inside each other delimited pressure ranges 7,8, in which different air pressures prevail. While a pressure area 8 is not evacuated, i. H. There is normal pressure other pressure range 7 connected via a line 12 to a vacuum source.
  • the suction roll has a rotatable roll shell 2 with a perforation in Form of through holes 9.
  • the negative pressure in the pressure area 7 causes sucking in air through the perforation of the roll shell 2.
  • FIG. 2 shows the use of the suction roll in a machine for producing a Paper, cardboard, tissue or other fibrous web 1 shown.
  • the Fibrous web 1 runs here together with an air-permeable band on both sides 10.11 to the suction roller. Then the fibrous web 1 wraps together with the inner band 10 the part of the roll shell 2, which with the Vacuum source connected pressure range 7 limited. This negative pressure causes through the perforation of the roll shell 2, a suction of the fibrous web 1 the band 10 and thus stabilizes the run of the fibrous web 1.
  • the reinforced Adhesion of the fibrous web 1 it is possible during the wrapping of the Suction roller to guide the outside band 11 away from the fibrous web 1.
  • the belt 10 After the wrapping, the belt 10 leads the fibrous web 1 to one in alone Web running direction 13 following unit of the machine.
  • the pressure areas 7, 8 are opened from one to the roll shell 2 Pressure box 6 and the roller shell 2 limited.
  • the pressure areas 7,8 here extend axially over the entire length of the Suction roll. However, it is also possible to axially have a plurality of pressure ranges 7, 8 to be arranged side by side.
  • the seal is rotated by one in one Seal holder 4 mounted, cylindrical sealing element 3 is formed.
  • the axis of rotation of the sealing element 3 runs parallel to the axis of rotation of the Roll shell 2.
  • the contact pressure can be, for example, hydraulic or with a Compressed air filled pressure hose.
  • the sealing cylinder 3 is made of metal and rotates in the pressing essentially at the same speed as the roll shell 2. This significantly reduces friction and wear.
  • the sealing element 3 is axially along the Sealing element 3 extending row of nozzles 14 with a lubricant, here Water sprayed.
  • the lubricant can also, as shown in Figure 4, via a bore 17 to one Sealing element 3 open groove 18 of the seal holder 4 are brought. At the Covering the area of the groove 18 takes the outer surface of the Sealing element 3, the lubricant.
  • the arrangement according to FIG. 3 has a scraper 16 assigned to the sealing element 3 for removing the contaminants previously dissolved by the application of water.
  • the scraper 16 runs parallel to the axis of rotation.
  • the lubricant is supplied via a recess 15 of the seal holder 4 at the inlet of the sealing element 3 in the gap between the sealing element 3 and the seal holder 4.
  • a pressure area 7,8 is connected to an overpressure source, this can be done similarly implement a blowing zone or blowing roller.
