Definitions

  • the invention relates to a spinning beam for spinning a plurality of synthetic threads around a spinning system with such a spinning beam.
  • a spinning beam for spinning a plurality of synthetic threads, in which the spinneret plates are arranged in a row, is known from EP-163 248 B (Bag. 1416).
  • a spinning system with such a spinning beam is e.g. known from DE-PS 24 38 364 (Bag. 905) and DE-OS 41 03 990 (Bag. 1811) or the unpublished DE 195 13 941 AI.
  • the arrangement of the spinneret plates in a row results in a large longitudinal extension of the spinning system.
  • a spinning beam according to the preamble of claim 1 and a spinning system with such a spinning beam according to claim 2 are known from EP 0 285 736 B1.
  • the solution for the spinning beam results from claim 1.
  • the solution for a spinning system according to claim 2 results from the characterizing part of claim 2.
  • the spinning beam according to claim 1 has the advantage that all spinnerets are accommodated in a single heating box, the length of the heating box being limited in such a way that there can be no temperature differences along its length and that each row of spinnerets is assigned a multi-spinning pump is. This results in particular in the advantage of greater flexibility, since the entire spinning system does not have to be taken out of operation in the event of a fault on one of the pumps.
  • the spinning system according to claim 2 has the advantage that its blow box can be designed so narrow that it finds space in a narrow arrangement between two rows of nozzles.
  • the blow boxes can be independent of each other and supplied with blown air by two separate fans (claim 3).
  • the vertical cross-section of the blow boxes narrows in the direction of flow, so that the speed at which the blown air emerges through the blow walls in the direction of the filament bundle is essentially the same for all spinnerets of the spinneret row (Claim 4). It is also particularly advantageous in the case of an arrangement of two parallel rows of nozzles if, behind these rows of nozzles and between them, two similar blow boxes are provided back to back, which are separated from one another by a common partition (claim 5).
  • blow boxes arranged below and between the rows of nozzles are designed according to claim 6, since this embodiment is particularly space-saving and through
  • the design of the spinning system according to the invention has the advantage over the prior art that both sides of the spinning beam or the spinning system can be operated independently of one another, e.g. can be operated or shutdown with different throughputs and even independently of one another, if special operational requirements require this or make it appear expedient.
  • 1 shows a cross section through a spinning system.
  • 2 shows a longitudinal section through a spinning system;
  • 3 shows the bottom view under a spinning system;
  • the spinning beam is formed by the two side plates 2 and 3 and the top plate 4 and the lower parts 8.
  • the side plates 2 and 3 are U-shaped in profile.
  • the horizontal U-webs 5 and 6 form part of the top and bottom of the spinning beam 1.
  • the top plate 4 also has a U-shaped cross-sectional profile. It extends over
  • Spare sheet the entire length of the spinning beam 1. It has at least two holes over its length in its base plate, which are used to receive and weld one pump connection plate 11 each. This will be discussed later.
  • the top plate 4 is welded with its side webs 7 to the side webs 5 of the side plates 2 and 3, respectively.
  • the U-shaped opening of the profile points upwards.
  • a multiple pump 12 is pressure-tightly attached to each of the pump connection plates 11.
  • Each multiple pump 12 is driven by a pump shaft (drive shaft) 13.
  • the multiple pump 12 is a gear pump in which a melt flow is fed through melt line 23 and distributed to several pump chambers and then distributed to several distributor lines 14.
  • the melt line 23 is heated by a heating jacket 15. It connects the melt source (eg extruder not shown) to the spinning beam 1.
  • a melt feed line 23 leads into the spinning beam 1.
  • This melt feed line 23 penetrates the base side of the top plate 4 and is then connected to a distributor piece 25. From the distributor piece 25, the melt is distributed to the melt distributor lines 26, one of which leads to a pump connection plate 11 and one of the pumps 12.
  • the pump connection plates 11 each lie centrally over six nozzles 18.
  • the melt flow is fed to the multiple pumps 12 through the melt distributor line 26, which is then distributed by the pumps 12 to 6 distributor lines 14 in each case.
  • one distributor line 14 leads to a spinneret 18 by opening into the nozzle pot 17 via the channel 28.
  • nozzle pots 17 are identical. Rectangular nozzle pots are possible in horizontal section.
  • two lower plates 8 are provided in a U-shaped cross-sectional profile.
  • the U-webs 16 of the lower plate point downwards and are at their lower ends with the
  • each sub-plate 8 has a plurality of holes which are arranged at equal intervals, e.g. B. six holes. Terminal plates 9 are inserted into these holes and welded to the lower plate 8.
  • Each of the connecting plates 9 projects with a connecting piece 20 into the U-shaped mouth of the lower plate 8.
  • the connecting piece 20 has a thread 19 on its circumference.
  • the nozzle cup 17, which has a corresponding mating thread on its inner circumference, is screwed to this thread.
  • a spinneret 18 is inserted into the bottom of the nozzle pot 17.
  • a piston 21 is movable in the nozzle cup 17.
  • This piston 21 is sealed against the lower connecting piece 20 of the connecting plate 9 by a round seal 22 which surrounds the feed line 28.
  • the piston 21 is sealed by a membrane 24 on its side facing the nozzle plate 18.
  • the melt line 28 penetrates the piston 21 and the membrane 24 in the middle.
  • the membrane 24 abuts the piston 21 under a slight pretensioning force and presses it by means of the sealing ring 22 against the lower end face of the connecting piece 20 of the connecting plate 9.
  • the membrane 24 settles due to the pressure of the melt penetrating into the nozzle pot 17 against the piston 21 and the gap that surrounds this piston and thereby seals the piston 21.
  • the piston and the sealing ring 22 are pressed against the connecting piece 20 of the connecting piece 9 with the required sealing force.
  • the nozzle pack in the nozzle pot 17 is therefore preferably self-sealing.
  • the spinning beam 1 thus has two rows of nozzles 181, 182, each consisting of six nozzles 18.
  • the rows of nozzles are arranged at a short distance from one another.
  • a pump 12 is assigned to each row of nozzles 181, 182.
  • the pump 12 is located approximately in the middle above each row (see FIG. 2).
  • the two pumps are fed in particular from a common melt supply line 23.
  • the melt flow is distributed over six distribution lines 14 each.
  • the distribution lines have the same length and must therefore be on a more or less
  • the distance between the two rows of nozzles is selected so that the distributor lines 14 do not interfere with one another.
  • the melt feed line 23 is fed through an extruder, not shown.
  • the spinning beam 1 itself is with a heating medium, for. B. diphyl steam.
  • a total of twelve threads can be spun with the spinning beam 1, each consisting of a large number of filaments.
  • a cooling device 29 is arranged below the spinning beam 1, specifically in the distance between the two rows of nozzles 181, 182.
  • the cooling device is a flat, perpendicular cuboid, which extends along the rows of nozzles.
  • the cooling device is divided diagonally by a vertical partition 30. This results in two blow boxes 31 and 32.
  • the front wall 33 of each blow box 31, 32 which faces one of the nozzle rows 181, 182 or the filaments emerging from it, is permeable to air and is designed and referred to as a blow wall 33.
  • the air chambers 34 and 35 In front of the two narrow end faces of the blow box 31, 32 are the air chambers 34 and 35, which are each connected to the blow box 31 and 32 via an air slot 36 on the end faces.
  • the air slot 36 extends essentially over the entire height of the blow box.
  • Each of the air chambers 34, 35 is connected to an air connection 37 which opens into the air chamber 34, 35 from below.
  • the air chamber extends over the substantially entire height of the blow box, and in such a way that its cross section decreases steadily, as shown in FIG. 2. This can be accomplished by arranging the side wall 38 facing away from the blow box 31, 32 at an angle, so that the air chamber 34, 35 tapers essentially conically upwards (FIG. 2). But it can also - which is not shown here, the side walls 39 (FIG. 3) adjoining the blow box, so that the air chamber 34, 35 extends over their
