Definitions

  • the invention relates to a spiral sieve made of plastic spirals for paper machines.
  • the invention is therefore based on the object of creating a spiral screen which has a top which is as dense and homogeneous as possible, has no seam zone in the closed state and can therefore also be used in the wet end in the paper machine.
  • the top should also be such that the screen can also be used for papers with the highest quality requirements.
  • a flock height of up to 3 mm is sufficient for the dryer section in the case of sieves, the fibrous web being formed from polyester fibers.
  • the flock height is greater than 3 mm and the fibrous web consists of polyamide fibers. If necessary, mixed flocking from fibers of different lengths is also possible.
  • all other types of synthetic fibers used in dry or wet areas can also be used. The Beflok - hence, kung each application adaptable.
  • the sieve is formed from flattened spirals, i. that is, if the filaments consist of flattened wire at least on the top of the sieve.
  • the fiber pile is colored black. This coloring causes the screen to heat up a lot, which has a favorable effect on the drying process.
  • a further embodiment of the invention proposes a method for producing the spiral screen, in which, according to the invention, individual spiral screen segments are subjected to flocking and the flocked segments are connected to form a screen.
  • a spiral sieve is formed from the plastic helices for this purpose, which is subjected to a pre-thermosetting. The sieve is then divided into segments, the size of which is determined by the size of the flocking machine, and the segments are flocked. The flocked segments are then joined together again to form a spiral sieve. This sieve is supplied open and endlessly assembled in the paper machine.
  • the relevant segments are provided with an adhesive layer and guided over the negatively charged metal plate of the flocking machine.
  • the container for the flocking material is charged positively.
  • the flocking height is determined by the length of the individual fibers.
  • the flocking density is predetermined by the flocking duration and other usual parameters.
  • the temperature of the pre-heat setting is set such that it is above the drying temperature for the flocked segments and that the latter is higher than the temperature of the final heat setting of the entire screen.
  • FIG. 1 An endless spiral sieve made of plastic coils for paper machines is not shown, since sieves of this type are generally known.
  • Fig. 1 the segment of such a screen is therefore shown schematically in a side view.
  • the segment 1 consists of a plurality of plastic helices 2, which are connected to one another by the plug wires 3.
  • the top 4 of the segment 1 and thus also of the spiral sieve is provided with flocking from the fiber pile 5.
  • the segment was coated with an adhesive 6 before flocking.
  • the flock height 7 was chosen with regard to the purpose of the paper screen.
  • the wires 8 of the coils 2 are flattened on the outside of the sieve.
  • the individual segments 1 are joined together to form an endless sieve. For this, it is advantageous if the end coils 10 and 11 are removed before the connection process in which the plug wires 12 and 13 are removed.
  • the new end coils of segment 1 which then arise are connected to one another with the end coils of the adjoining segments formed in the same way by inserting the coils into one another and inserting a plug wire.
  • the segment 15 shown in FIG. 2 has essentially the same structure as the segment 1 according to FIG. 1, with the difference that the wires of the coils 2 are not flattened on the upper side of the segment and that one on the fiber pile 5 Fleece layer 16 is placed and needled to the segment.
  • the application of the fibrous web to the top of the segment takes place in the same way as described in FIG. 1.
  • the fabric sieve 21 consists in the usual way of warp and weft threads, the warp threads ending at the connection point of the seam in loops 22, in which the spirals 23 and 24 engage.
  • Pins 25 and 26 serve for the articulated connection of the helixes 23 and 24 inserted into the loops 22.
  • the helixes 23 and 24 are connected to one another by means of the pin 27 provided on its top 28 with the flocking 29.
