Definitions

  • the invention relates to a device for laying a nonwoven, in particular a Toiletfilzleger, in which a card web is deposited on a delivery conveyor belt of great width to a nonwoven.
  • nonwoven layers have long been known and usually designed as a co-casual Leger, in which a superstructure and a laying carriage each reciprocate in the same rhythm and the same direction.
  • Two pile conveyor belts serve to transport the card web to the depositing gap in the laying carriage, wherein in a section between the superstructure and the laying carriage, the card web is sandwiched between two sections of the two conveyer belts.
  • a secure guidance of the card web is guaranteed to Ableggespalt in the laying carriage.
  • the pile conveyor belts with their lower sections simultaneously serve as cover tapes which cover the laid non-woven fabric.

  • a particularly embodied embodiment of a nonwoven layer is known from EP 1 816 243 A1 known.
  • a supporting carriage is provided, which is located on the side facing away from the upper carriage side of the laying carriage and supports the lower run of the running on this page Flortransportbandes.
  • the support car with the speed of the upper carriage is movable and especially helpful when the laying carriage is located close to the superstructure, because then the bridged by the lower strand of the to be supported pile conveyor belt distance is particularly large.
  • the present invention is therefore based on the object of specifying a device for laying a nonwoven, are further avoided in the blowing in the pile and thus ensures a particularly uniform storage of the web.
  • the device for laying a nonwoven fabric from a card web has a transfer belt lying transversely to a delivery conveyor belt above the same movable laying carriage, a superstructure and two pile conveyor belts for guiding the card web over the superstructure and the laying carriage into a delivery gap formed on the laying carriage, wherein in an area between the upper carriage and the laying carriage two sections of the two pile conveyor belts for receiving the card web between the sections extend at least partially parallel.
  • At least one support roller is arranged in the region of the arranged between the superstructure and the laying carriage sections of the two Flortransportb respectively.
  • the at least one support roller is arranged in a movable support carriage.
  • the support carriage is preferably movable parallel to the direction of movement of superstructure and laying carriage. This ensures that the support car movement Not affected by superstructure and laying carriage and at the same time an arrangement of the support carriage in each case in the middle between uppercarriage and laying carriage is possible to evenly subdivide the space between the superstructure and laying carriage, which must bridge the two Flortransportbs.
  • the drive of the support carriage is preferably coupled to the drive of the laying carriage or the upper carriage.
  • a chain or a toothed belt is preferably mounted on the support carriage, which is guided via a drive gear connected to a motor and a deflection wheel, wherein the drive gear is driven by the same shaft as a drive gear of the laying carriage or the superstructure, but has a different circumference than this ,

  • the two support rollers are arranged at a distance next to each other and arranged the two between the superstructure and the laying carriage Sections of the two Flortransportb selected run through the space between the support rollers. In this way, an even better avoidance of belt vibrations can be ensured by generating a slight tension in the belt section between the support rollers.
  • the device is preferably designed as a co-casual.
  • the support car is preferably located at a level with and between the uppercarriage and the laying carriage, which simplifies the overall kinematics of the web laying machine.
  • the drive of the support carriage is designed such that the support carriage moves synchronously with the superstructure and the laying carriage and at a speed which is between the speed of the laying carriage and the speed of the superstructure.
  • the first pile conveyor belt on the superstructure forms a tape inlet with an obliquely downwardly sloping inlet section and is also returned through the laying carriage and parallel as a pile conveyor belt over the delivery conveyor belt to the superstructure, and the second conveyor belt is movable only over a transversely to the delivery conveyor belt Tensioning car, but not passed through the superstructure.

  • the driven guide roller 7 is coupled to a motor (not shown) and is intended to cover the cover 6 in different To drive directions.
  • the other guide roller 5, which is rotatably mounted in the clamping carriage 3, partially wrapped by a Flortransportband 11, which is further referred to in the second Flortransportband 11, via a driven guide roller 12 and a stationary guide roller 13 to one in the first clamping carriage 10th mounted second deflecting roller 14 is guided, which is partially wrapped by the pile conveyor belt 11, from where the pile conveyor belt 11 via further stationary guide rollers 12a and 13a to the laying carriage 3 runs back.
  • the second pile conveyor belt 11 has a lower run, which runs at a close distance above the delivery conveyor belt 1.
  • the driven deflection roller 12 is coupled to a motor (not shown) and is intended to drive the second pile conveyor belt 11 in different directions.
  • a chain or a toothed belt 15 is mounted, which via a motor (not shown) connected to the drive gear 16 and a guide wheel 17 runs. With the aid of these drive devices, the laying carriage 3 can be moved back and forth across the delivery conveyor belt 1 transversely to its transport direction.
  • an upper carriage 18 is mounted so as to be movable transversely to the transport direction of the delivery conveyor belt 1 on rails or tubes 3a in the machine frame.
  • the rails or tubes 3a may be the same rails or tubes on which the laying carriage 3 is mounted movable.
  • the uppercarriage 18 has an upper guide roller 19 and a lower guide roller 20, which are laterally offset from each other. About these two guide rollers 19 and 20 runs another Flortransportband 21, which is subsequently called first Flortransportband 21. In the area bounded by the two guide rollers 19 and 20 in the uppercarriage 18, the first pile conveyor belt 21 is inclined obliquely downwards.
  • the first Flortransportband 21 runs parallel to the upper strand of the second Flortransportbandes 11.
  • the first Flortransportband 21 is after the laying carriage 3 via a stationary mounted, motor-driven guide roller 25 and from there via a in a second clamping carriage 23rd mounted deflecting roller 24 out to then over several stationary in the machine frame mounted (hereinafter "stationary") guide rollers 22 to run before it reaches the upper carriage 18 again.

  • the pile conveyor belts 6 and 11 form at the point where they are deflected in the laying carriage 3 of their guide rollers 4 and 5, a gap which is initially referred to as a discharge gap.
  • the second pile conveyor belt 11 is driven so that its upper run follows the movement of the lower run of the first pile conveyor belt 21 because both belts enclose the pile web on their way between the upper carriage 18 and the laying carriage 3 between them.
  • a total of three bands were included in the nonwoven.
  • the invention can also be applied to all other nonwoven layers, inter alia, those with two strips, as long as the two pile conveyor belts 11, 21, the card web in the area between the superstructure 18 and laying carriage 3 at least partially sandwich.
  • a support roller 28 is now arranged in the region between the uppercarriage 18 and the laying carriage 3, which can be designed as part of a support carriage 30.
