Definitions

  • the invention relates to a nonwoven layer with the features in the preamble of procedural and Device main claims.
  • Such a fleece layer is known from EP-0 609 907 A2 known.
  • the trained as a so-called band layer Fleece layer has two relatively movable Main carriage and two endless and looped all-round driven laying tapes.
  • the tapes are running parallel at least in the section between the main carriages, taking up and guiding the pile between them.
  • the fleece layer on the input side has a pile pick-up a so-called tape infeed of the laying tapes. That of two Side tapes come together here and form an inlet section with an opening angle of the tapes of at least 20 °.
  • the inlet slot on The entrance to the inlet section is therefore very large and much wider than the pile thickness.
  • the one Laying tape fed pile is in the tape infeed with a obtuse angles obliquely downwards against the horizontal redirected. Due to the large opening angle and the wide Inlet slit, the pile is open in the inlet section and is only at the bottom between the two adjacent pulleys between the laying tapes clamped and guided on both sides.
  • the pile can be in the Inlet section at high speeds from the bottom Lift off the tape. This can be especially the case with sensitive Lead to faults. In this arrangement, the Feed speed limited.
  • FR-2 553 102 shows another nonwoven layer.
  • the two laying tapes have two parallel juxtaposed and straight belt sections that are extend vertically downwards, making the horizontal fed pile at the belt inlet a deflection of 90 ° experiences.
  • such Belt infeed also only for limited Feed speeds of the pile and Working speeds of the fleece layer can be used. If the feed speeds get too high, it can to demolish in the very light and highly sensitive Fiber pile come.
  • WO 91/15618 shows a further variant of the Belt infeed, in which both laying tapes over the main carriage two large deflection rollers are guided. This forms there is also another inlet funnel for one Placing tape fed pile.
  • the two large deflection rollers are horizontally next to each other at about the same height arranged, whereby the pile only about at midpoint of the two rollers by the ones that come close together here Laying tapes are recorded and guided on both sides. Before and then the tapes pass through the roller shape apart again.
  • These two aforementioned fleece layers are for higher feed speeds of the pile and Processing speeds of the fleece layer designed.
  • the tape inlet according to the invention as in the prior art, there is an inclined downward sloping inlet section, which, in contrast to the prior art, is formed by two tape sections running close to one another.
  • the belt sections form a narrow inlet slot between their adjacent deflecting rollers when they enter the belt inlet, which slot is adapted to the pile thickness.
  • the two belt sections take up the fed pile and guide it on both sides and / or cover it.
  • the band sections are at an obtuse angle against the Feed or infeed direction directed obliquely downwards.

It is advantageous to use the lower one Deflection point to provide at least one belt loop. In a particularly advantageous embodiment There are at least two strap loops, the first Band loop in front of the deflection point and the second Band loop is arranged behind it. This will result in the critical points of the diversion Relative speeds of the laying tapes or their Band sections prevented.

  • the one running between the uppercarriage and the laying carriage Outlet path can also be at an angle to Horizontal run. This allows one more Reduction of the deflection angle of the pile in the superstructure and a reduction in the centrifugal forces acting on the pile in the redirection area.
  • the lower laying tape in the inlet section can be in one Run straight ahead of the inlet. Of the The pile is fed from a feed belt onto this laying belt transfer. Alternatively, this can be done in the inlet section lower laying tape also designed as a feed belt be. In this case, the lower tape can be used for formation of the inlet gap before the inlet is redirected twice be.
