Definitions

  • WO 00/73032 discloses a method of operating a device for laying a web of finite fibers after the air laying process, wherein the device consists of a rotatably mounted laying drum whose jacket is permeable to the fibers.
  • the laying drum is flowed through by a stream of air radially in the direction of an endless belt carrying the nonwoven to be laid and advancing along the laying drum, wherein the fibers to be laid to a fleece are fed centrically and frontally in the axial direction of the laying drum.
  • the feeding of the pulp fibers is done according to this prior art unilaterally and alternately by two drums of a laying drum pair, the drums are mounted axially on one side, but on the Faserzu slaughter on the outer surface of the drum.
  • Within the laying drum is a comb drum whose combs touch the surface of the laying drum.
  • each laying drum is parallel to a second drum assigned, which must be connected to each other via pipes, which also attack on the end faces.
  • a laying device thus consists of two laying drums, between which fibers flow in the circulation.
  • the laying drums extend over the entire working width, which can reach up to 4 or 5 m.
  • the drums In order to achieve a uniform distribution of the fibers on the endless belt, the drums must have a corresponding diameter. However, this is limited by the required dimensions of the ball bearings, which are arranged for the rotatable mounting of the laying drum at its outer diameter. The reason for this are the necessary eccentric openings in the end faces of the laying drums.
  • the ball bearings can not be built in any size in their diameter now. At a higher speed - as is necessary here in the operation of the laying drum - run the balls of the ball bearings too large diameters, which are over one meter, in the bearing shells too fast, so that the lubricating film breaks off.
  • the invention has for its object to find a solution to the problem.
  • the laying drums should be made in any desired diameter, the namely results from the respective width of the web to be laid.
  • a larger diameter of the laying drums for the production speed of the web to be laid is advantageous.
  • the solution is found in that the fibers are fed centrically on both end faces of the laying drum.
  • the device for laying a web of finite fibers as well as pulp fibers by the air laying method is provided with a rotatable mounted in a housing permeable laying drum with a centric end opening for feeding the fibers, wherein the laying drum is disposed above a nonwoven to be laid endless belt, which is assigned below a suction box for sucking the laying drum radially above the supplied air.
  • the front-side openings for feeding the fibers into the laying drum are now arranged centrically on both sides. It is thus the axis of the laying drum designed as Faserzu meltrohr, which must have only such a large diameter that the necessary amount of fibers can be introduced.
  • the diameter of the necessary ball bearings for the rotatable mounting of the laying drum is completely independent of the outer diameter of the laying drum.
  • the laying drum can be built to any extent, the ball bearings will never run hot even at high peripheral speed.
  • a comb drum In the laying drum, a comb drum is to be stored, the combs of which rub on the inside of the mantle of the laying drum and convey the fibers through the openings of the mantle.
  • This comb drum is also stored centrally in the laying drum, and indeed this comb drum forms the fiber insertion opening in the axis and the bearing of the laying drum is then arranged around the corresponding insertion tube.
  • a laying drum 3 is rotatably mounted.
  • a ball bearing 4 which is arranged in an opening 5 of the housing 1.
  • a further ball bearing 7 is arranged, which supports the tubular axis 8 of a comb drum 9.
  • the central opening 10 of this tube axis 8 is to be sized so that the through this opening 10 incoming fibers are timely and completely over the length of the drum 3 can be introduced. Irrespective of this, the diameter of the laying drum 3, which can take any measure determined by other parameters, is independent.
  • Such a fiber insertion opening 10 is provided on both end sides of the laying drum. The fibers are therefore not conveyed around between two drums in the circuit, but only a laying drum 3 forms a laying unit.
  • the comb drum 9 consists of two circular end plates 11, 12, which have the fiber inlet openings 10 in the center. On the outer circumference are attached around tubular supports 13 which extend parallel and axially of the inner shell of the laying drum 3. Radially outwardly radially directed combs 14 are mounted centrally in the tubes 13, which ends in height of the inner surface of the jacket of the laying drum 3. Both the laying drum 3 and the comb drum 9 driven to run, with a relative speed between the drums, this can be the same direction or also directed opposite.
  • a suction box 15 is arranged, through which the top of the laying drum 3 supplied air 16 is sucked.
  • the emerging from the laying drum 3 fibers arrive with the air flow on the endless belt 2, lie down there and form the fabric to be produced.
  • the endless belt 2 or the fleece lying thereon is sealed by a sealing roller 17, 18 to the suction box or to the housing 1.
  • any number of single-drum device can be arranged one behind the other. So it is not necessary drum pairs.
  • the adjacent laying devices require only one wall 19 for separation.
