Definitions

  • the invention relates to a drying section in a machine for producing and / or treating a fibrous web according to the preamble of patent claim 1.
  • a fluid medium such as. Water is applied to the fibrous web.
  • the moistening devices are arranged, for example, in single-row dryer groups, usually directly below the suction rolls (suction suction rolls) around which the fibrous web is guided on the drying fabric running between the fibrous web and the outer surface of the suction roll.
  • This arrangement of the moistening device has the disadvantage that on the housing of the moistening device, in particular in the gap formed between the outer surface facing the outer surface of the roller and the outer surface of the roller, the usually only 80-800mm (about 80-150mm in the operating position of the Befeuchtungseinrichrung and about 100-800mm in the inoperative position of the Befeuchtungseinrichrung) is wide, soiling, such as paper scraps, can accumulate, for example, can occur when the web is broken. Often also scraps of paper accumulate during transfer of the paper web in the gap between the lateral surface of the roller and the outer surface of the housing of the moistening device facing the lateral surface of the roller, even though the moistening device is in the inoperative position during transfer.
  • the object is achieved by a machine for the production and / or treatment of a fibrous web with a section of a wire looping around a sieve.
  • the screen is associated with a moistening device with a housing of the outer surface of the roller opposite.
  • the fibrous web is further guided on the wire around the roller so that one side rests on the wire and the other side is exposed.
  • the moistening device is arranged such that the moistening device can act upon the other side of the fibrous web with a fluid application medium.
  • the machine according to the invention is characterized in that the housing of the moistening device extends in the web running direction only on a portion of the screen on which the fibrous web runs upwards.
  • the invention is based on the idea that in the position of the moistening device in which the fibrous web is guided upwards, almost no remains of the fibrous web can reach the housing of the moistening device, since the fibrous web on the wire looping around the web in the web running direction often first down and is subsequently guided upward and thus arrive at a web break or in a railway overpass resulting web residues directly into the machine cellar and not to the housing of the moistening.
  • the housing of the moistening device extends in its extension along the upwardly extending sieve, rests or shreds of the fibrous web, which nevertheless reach the housing, bounce off or slide down from the latter.
  • the invention thus proposes a machine for producing and / or treating a fibrous web with a greatly reduced tendency to soiling the moistening device and thus significantly increased productivity.
  • web running direction is to be understood as meaning the spatially changing running direction of the fibrous web in the machine
  • machine direction is to be understood as meaning the longitudinal extent of the machine for producing and / or treating a fibrous web
  • the housing comprises an outer surface facing the outer surface of the roller with at least one opening for the outlet of the fluid application medium and extends to the outer surface of the housing facing the lateral surface of the roller in the web running direction substantially along the portion of the screen, on which the housing extends in the web running direction.
  • the housing extends in its length in the web running direction, so that the housing is relatively "slender" in its other dimensions that do not extend in the web running direction and therefore reduced contact surfaces for the accumulation of dirt, such as scraps the fibrous web, has.
  • the housing is arranged in the machine direction next to the roller, i. depending on the direction of web travel before or after the roller, and extends in its length at least in sections over the same height as the roller.
  • a further embodiment provides that the wire is guided in the looping region of the roller between the lateral surface of the roller and the fibrous web.
  • a preferred embodiment of the invention provides that the sieve is guided along the portion on which extends the housing at least in sections on the roller. Further preferred, when the wire along the portion on which the housing extends, is first guided in the web running direction on the roller and subsequently runs away from the roller upwards. In this case, the housing extends in the web running direction over the pick-up point of the screen from the roller away.
  • the housing of the moistening device thus has, for example, a sufficient size to accommodate further units, such as, for example, an extraction or the like.
  • the outer surface of the housing facing the lateral surface of the roller is formed by a nozzle plate which, in particular in the cross-machine direction, is curved in an untwisted manner and in a web running direction, i. the Siebbahn following, runs.
  • the housing extends in the web running direction along the wire over a horizontal line which extends through the center of the roller.
  • the housing in the web running direction with respect to a passing through the center of the roller vertical line a maximum over an angular range of greater than 0 ° to 150 ° , preferably from 30 ° to 130 °, extends when the considered angular range at the vertical is 0 ° and increases in the web running direction.

  • the atomizer nozzle may, for example, be a pneumatic atomizer nozzle or a multi-component nozzle, in particular a two-component nozzle.
  • Two-fluid nozzles are, for example, in the DE199 49 236A described.
  • the fluid application medium is a liquid, in particular water, chemicals or a mixture thereof.
  • the atomization of the application medium in the nozzle by means of a sputtering gas, such as. Air or steam.
