Definitions

  • the invention relates to a method for zone-by-zone application of fluffy material to a web-shaped, forward-moving base, a device for carrying out this method and a use of this device.
  • Powdery liquid-absorbent material has the disadvantage, however, that after the diaper has been produced between the paper fibers, it can come to the outside of the diaper and thus come into skin contact with the skin surface of the toddler to be diapered, which is undesirable.
  • the object of the present invention is, in particular, to provide a method which, in precisely metered form, enables flakes to be applied zone by zone to a forwardly moving base, such as a diaper web made of paper fibers.
  • the invention further relates to a device for carrying out the method according to the invention.
  • the invention also relates to a use of the device according to the invention as claimed in claim 15.
  • a fiber-bonded liquid absorber based on polyacrylate in Form of flakes is applied zone by zone to a paper web.
  • a liquid absorber is sold, for example, by the Hanfspinnerei Steen & Co. GmbH., D-2053 Schwarzenbek, under the name SAFF.
  • the device shown for the zone-by-zone discharge of fluffy absorption material 1 onto a web-shaped, continuously advancing base sheet 2 has a level-controlled storage container 3 for receiving the absorption material flakes 1 to be discharged and a controllably adjustable metering arrangement 5 which interacts with the outlet opening 4.
  • This metering arrangement 5 consists of an endless needle belt 8, which is guided over two deflection rollers 6 and 7, the latter at its flake dispensing point B being in engagement with a rotating floack wiping roller 9, which hangs from the storage container in the needles projecting outward from the needle belt 8 3 stripped flakes 1 on the applicator assembly 10.
  • the continuously rotating application arrangement 10 has, as can be seen in particular from FIG. 4, an application belt 12 which is designed to be air-permeable to zones on the support web 2 and is evident from FIG. 5 and which is guided over the deflection rollers 13, 14 and 15.
  • the application tape 12 consists of an air-permeable wire or synthetic fiber fabric, which is coated with an air-impermeable plastic 17 except for the zones 16 corresponding to the desired application pattern 11.
  • the continuously rotating application belt 12 or its zone-permeable, air-permeable flock receiving points 16 stand during their movement from the delivery point B of the metering arrangement 5 until engagement with the underlay web 2 to be occupied, via a vacuum chamber 18 formed on the inside of the application belt 12 with a vacuum source 19 in connection.
  • a blowing nozzle 21 directed towards the belt surface can additionally be provided, the blowing effect of which, however, is limited in such a way that the absorption flakes held on the belt surface by the regions 16 in these regions 16 are not also blown away.
  • the air-permeable belt regions 16 are uncoupled from the negative pressure when they overflow over the deflection rollers 14 and 15, they are designed as slotted rollers, as can be seen from FIGS.
  • the webs 22 between adjacent suction slots 23 should of course be as narrow as possible in order to achieve a suction effect that is as extensive as possible.
  • suction slits, bores, pores or other air-permeable designs of the deflection roller outer sides are also conceivable.
  • an overpressure chamber 24 is arranged in order to transfer the flakes located in these areas 16 to the top of the underlay 2 with the help of overpressure acting through the areas 16.
  • a vacuum chamber 25 acting in this flake transfer area from below through the underlay 2 can also be provided.
  • the deflecting roller 13 can, like the other deflecting rollers 14 and 15, also be designed as a slotted roller and connected to an overpressure source at this deflecting point or also integrated into the overpressure chamber 24.
  • a cleaning roller 26 can also be provided for the complete cleaning of the application belt surface from any flakes and / or flake components that are still on the surface.
  • the drive of the metering arrangement 5 and the discharge arrangement 10 is controlled in a controlled manner as a function of the speed of the support web 2 determined with the measuring device 27 with the aid of a computer 28.
  • FIG. 6 shows a second exemplary embodiment of a device according to the invention, parts analogous to the first embodiment being provided with the same reference symbols, so that a repeated description of these parts is unnecessary.
  • a needle roller 8 'and a discharge roller 12' are used instead of a needle belt 8 and a discharge belt 12 ', but everything else can remain the same.
  • the flake container 3 is suspended in a vibratable manner via resilient suspensions 29 and connected to a vibrator 30.
  • the discharge roller 12 ' is also provided on its cylindrical outer surface analogous to the discharge belt 12 with the desired application pattern 11 corresponding air-permeable areas 16, and the stationary partition 31 separates the inside of the discharge roller 12' in a vacuum region 18 and an overpressure region 24th
