Definitions

  • the present invention relates to a needling device, particularly used in a needling machine to form a nonwoven pile.
  • This invention also relates to a needling machine equipped with such a device, as well as a method for forming a velvet, in particular a shaved velvet.
  • a needling machine comprises needles that are reciprocated through a web of nonwoven fabric and withdrawn from the web. By penetrating into the tablecloth, the needles consolidate the tablecloth and form loops giving the textile the appearance of a velvet. If the needles penetrate the textile from top to bottom, the loops are formed down below the textile web.
  • the web is generally carried by a carpet formed of brushes articulated between them. The needles emerge from the web down between the bristles of the brushes. The loops thus remain formed between the bristles of the brushes.
  • a stripper is used, above the sheet, to prevent the needles cause the sheet with them when they emerge from the sheet.
  • the loops formed during needling must have substantially uniform lengths. If some loops are less well formed and of insufficient size to be shaved, they remain in the form of a loop. Velvet uniformity is affected, and residual loops are traps for small elements, such as dust, chippings, crumbs, to which the velvet may be exposed. Velvet gets dirty faster; it is more difficult to clean, the elements being retained by the loops. This disadvantage is very significant, in particular for the velvet used for the interior lining of motor vehicles, more particularly as floor mats. If you cut very short a velvet to Irregular loops to shave even the shortest loops, the velvet maker then suffers a significant loss of material when shaving.
  • the document FR 2 704 007 discloses a method of manufacturing a needle punched velvet felt.
  • the document FR 2 105 180 A discloses a method of manufacturing a needled nonwoven fabric.
  • the document AT 322 870 B discloses a needling machine in which the needles of the last row or rows are arranged closely together, along a row.
  • the object of the invention is to provide a device for obtaining loops sufficiently regular to allow to shave the velvet in good conditions.
  • the loops located along the same transverse line of the web have a length which is a function of their respective age, that is to say according to a loop was formed at the beginning or at the end of the passage under the needles.
  • To standardize the length of the loops it would ideally be necessary for all the loops of the same transverse line to be formed at the same time. To get closer to this ideal, it is necessary to reduce the distance between the needles.
  • the débourreurs generally used today have the form of plates pierced with orifices distributed homogeneously and randomly, to avoid the marking of the textile. Each orifice of the plate is a passage for a respective needle through the stripper.
  • the distance between the needles is generally 7 to 8 millimeters. There is a minimum distance imposed by the need for sufficient mechanical strength of the plate, a distance that can be increased locally to meet the need for a random, that is to say irregular, distribution of the needles.
  • the needling device for forming a nonwoven fabric comprises a stripper and needles for the needling of a textile web, the needles being mounted on a needle board and intended to be actuated back and forth. through orifices of said stripper, said stripper comprising at least one zone where the orifices are defined between lamellae and can receive several needles.
  • a lamella is a structural element, or part thereof, having a small thickness measured parallel to the plane of the web.
  • a lamella may have a thickness close to or of the same order of magnitude or even less than a diameter of the needles.
  • the thickness of a lamella will advantageously be close to or of the same order of magnitude or even less than a desired distance between two neighboring needles.
  • the lamellae are advantageously substantially parallel to the direction of movement of the needles.
  • a thin lamella also makes it possible to limit the distance between two needles in two neighboring orifices separated by this lamella.
  • the distance between two needles is substantially similar or of the same order of magnitude or even less than a diameter of these needles.
  • two neighboring needles will advantageously be 3 to 5mm apart.
  • Each slat is preferably arranged to be in contact with one of its slices with the sheet, in order to maintain the sheet on the mat and prevent the sheet is driven by the needles when they perform their withdrawal movement.
  • the slats are biased relative to a direction of movement for the sheet in the device.
  • the lineage formation on velvet is avoided, reproducing in the final textile, the position of the slats.
  • a carpet formed of brushes articulated between them makes it possible to move and to carry the textile web in the device.
  • the loops formed by needling remaining anchored in the carpet brushes, the fact that the slats are biased does not cause transverse drift of the web.
  • the bias is chosen so that the angle formed between the slats and the direction of movement of the sheet is less than 45 degrees, preferably less than 30 degrees. Too great transverse forces can be limited and distributed if the slats are arranged to form a mesh between them, or if they are arranged to form rafters.
  • the mesh may for example form rectangles, squares or lozenges.
  • the rafters can form angles of which the bisector is transverse or longitudinal relative to the direction of movement of the web.
  • the slats can be arranged so that any point of the web, moving in the device, crosses at least one slat.
  • the needles can be grouped into one or more rows between two substantially parallel strips.
  • the needles may be staggered so as to optimize the density of the needles.
  • the zone composed of lamellae may be located downstream of a perforated area of the stripper relative to the direction of movement of the web in the device.
  • the stripper can then comprise, upstream, an area consisting of a plate pierced with orifices, a respective needle corresponding to each orifice.
  • This upstream zone makes it possible to reinforce the sheet by pre-needling, before denser needling, in the slatted area.
  • pre-needling consolidates the web by reinforcing the bonds between the fibers of the web, before the passage of the web in the slatted area.
  • the fibers being better bonded together, it is possible to increase the density of the needles between the lamellae while avoiding a phenomenon of jamming of the fibers between the needles.
  • the devices of the prior art avoids the risk of jamming by isolating each needle in the stripper, which has limited opportunities for bringing the needles.
  • the lamellar zone may advantageously represent 20 to 30 percent of the length of a needling zone, measured according to the direction of movement of the web in the device.
  • a slat deboner allows, without changing the stripper, a wide variety of arrangements for the needles, unlike a single-needle orifice stripper where it is necessary to change the stripper to change the position of the needles, each piercing in the stripper corresponding to a fixed position for a needle.
  • Such a change in the position of the needles is facilitated by a stripper according to the invention, especially since the change of a stripper takes about three hours, while it takes just a few minutes to change a needle board. So, by combining a provision particular needles, on one or more successive needling devices, with a given pitch of the web in the device can be, in a particularly simple manner according to the invention, creates and vary patterns in velvet.
  • the invention relates to a needling machine equipped with a device as previously described, in particular a needling machine adapted to form a nonwoven pile fabric.
  • the invention relates to a method for forming a nonwoven pile fabric, particularly a shaved nonwoven pile, characterized in that such a needling machine is used.

  • An endless belt 60 is mounted on the frame 110.
  • the frame conveys the web 7 in the needling machine between an input device and an output device not shown in the figures.
  • a needling head 104 is mounted movably relative to the frame 110, so that during needling, it is driven by a vertical reciprocating movement A.
  • a needle board 4 is fixed on the head 104 and animated by the same movement . Needles 3 are fixed on the needle board 4. They extend from this plate, vertically downwards, perpendicularly to the plane of the sheet 7.
  • the endless belt 60 is formed of brushes 6 articulated with each other. It is partially shown in FIG. figure 2 .
  • the web 7 of nonwoven fabric rests horizontally on bristles 8 of the brushes 6.
  • the hairs are oriented upwards.
  • the displacement of the belt causes the displacement of the ply 7 in the needling device, according to the direction of movement S.
  • the needle board 4 and the needles 3 attached to it are driven by the same vertical reciprocating movement A as the head 104, so that the needles penetrate and pass through the sheet and then emerge from below, where they form loops 5, between the bristles 8 of the brushes 6, then the needles are extracted from the web from above. This movement is repeated alternately during the movement of the web in the needling machine.

  • the stripper 101 defines a needling width L7 for the sheet 7.
  • the transverse dimensions L30 of the orifices 30 and L2 of the strips 2 are chosen such that an appropriate offset of each row relative to the others ensures that, over the needling width L7, any point of the sheet which passes through the needling device passes next to the same number of orifices. Such an arrangement allows a substantially uniform needling of the ply 7.
  • the width L2 of a lamella is equal to one third of the width L30 of a current orifice, so that a transverse offset of the value L2 between two adjacent rows makes it possible to ensure that each point of the lap, which regardless of its position on the needling width L7, passes opposite three orifices 30 and facing a lamella 2.
