Definitions

  • the present invention relates to the field of manufacturing of an air-woven nonwoven designated under the name "airlay” technique. It relates more particularly to a machine improvement for the formation of a nonwoven by airway which significantly increases the production speed, without prejudice to the quality of the nonwoven form.
  • the "airlay” technique is essentially characterized by the dispersion in a room and the projection on a surface of mobile reception, of individual fibers by means of an air flow high speed, said receiving surface being breathable and allowing the formation and transport of the nonwoven.
  • non-woven the veil of fibers formed by the "airlay” technique, even if this veil has not undergone special binding treatment.
  • the means which are capable of creating inside the dispersion chamber an air flow allowing scatter the fibers inside the chamber and project them onto the training and transport surface consist in particular of suction means arranged below the forming surface and for transporting the nonwoven, which is breathable.
  • downstream wall of the dispersion is a plate whose lower edge is applied to the surface of the nonwoven leaving said chamber, the box of suction being arranged over the entire surface which extends vertically from the bottom edge of the upstream wall and the bottom edge of the wall downstream of the dispersion chamber.
  • Upstream and downstream are defined in relation to the direction of displacement of the formation and transport surface of the nonwoven.
  • the contact of the lower edge of the wall downstream of the dispersion chamber with the surface fibers of the nonwoven generates friction which is likely to cause irregularities on the nonwoven fabric, especially since the speed of displacement of the formation and transport surface of the nonwoven is important.
  • the front wall of the dispersion is porous in its lower part, said lower part having preferably a curved profile substantially in an arc.
  • the sheet thin microperforated which constitutes the lower part of the downstream wall of the dispersion chamber exerts a weak force on the nonwoven compression which compresses it slightly. This provision prevents the suction flow created by the suction box does not generate an incoming air flow which would enter the interior of the dispersion passing between the lower edge of the downstream wall and the strand the upper surface of the formation and transport of the nonwoven, a such air flow being detrimental to the quality of said nonwoven.
  • the low, porous part of the front wall of the dispersion chamber can also be constituted by a porous rotary cylinder, in particular a microperforated cylinder.
  • This embodiment makes it possible to avoid friction, when the cylinder is driven at a peripheral speed which is equal to the speed of movement of the formation surface and transport of the nonwoven.
  • the present invention aims to provide a machine for the formation of an aeraulic nonwoven, which overcomes the disadvantages of the aforementioned known machines.
  • said means are suitable for carrying out aspiration in an area - called suction area - from the formation and transport surface of the nonwoven which extends under the dispersion chamber and downstream of it, with a decrease in the suction speed between upstream and downstream of said area.
  • the downstream wall of the dispersion is a plate whose lower edge delimits, with the strand the upper surface of the formation and transport of the nonwoven, a passage space whose height is greater than the thickness of the nonwoven leaving the dispersion chamber.
  • the downstream wall of the chamber dispersion is a rotary cylinder, preferably porous or perforated.
  • This variant is particularly advantageous when it is necessary to compress the veil of fibers, to evacuate the air contained between the fibers.
  • the suction means are consist of a single suction box, in which the conditions suction are decreasing from upstream to downstream of the area suction.
  • the suction means are consisting of a multi-stage suction box, each stage having separate suction conditions.
  • a first stage with the highest suction speed V1 is arranged under the dispersion chamber in a main section of the suction zone extending up to a distance d - preferably from 5 to 20 mm, for example 10 mm - plumb from the bottom edge of the downstream wall of the dispersion chamber and at least one second stage, developing a suction speed V2 lower than V1, extends downstream of the first floor on a secondary section of the area suction.
  • the speed is not uniform over the entire length of the chamber suction speed, the highest suction speed in the section main, located upstream of the suction zone, which corresponds to the first suction stage while lower in the section secondary of the suction zone which extends beyond the first floor, especially over distance d.
  • the machine in the secondary section of the suction zone, has a single second stage in which the suction speed gradually decreases, from upstream downstream of said secondary section.
  • the machine in the secondary section of the suction zone, has a plurality N of seconds successive stages.
  • the suction speed can be constant in each of these N second stages or may be decreasing progressive from upstream to downstream of said floor.
  • the machine in the secondary section, has a pressure roller, preferably porous or perforated, arranged transversely above the transport surface nonwoven, suitable for applying to the veil of fibers beyond the downstream wall of the dispersion chamber.
  • the pressure roller is arranged directly above a partition separating two second floors in the secondary section.
  • a machine for manufacturing a nonwoven by air comprises a conveyor implementing a 1 porous conveyor belt which is tensioned on drive rollers.
  • the upper strand 1a of this conveyor belt 1 which in the examples illustrated is substantially horizontal, is driven at a constant speed predetermined in the direction of transport indicated by arrow F.
  • This upper strand 1a of the conveyor belt 1 forms a surface breathable, which allows both the formation and transport of nonwoven.
  • This machine also includes a chamber 2 of dispersion of the fibers, which overcomes the upper strand 1a of the strip conveyor 1 and which extends over the entire width of this upper strand 1a.
  • This dispersion chamber 2 has an upstream wall 3 and a downstream wall 4, which extend transversely to the direction of movement F of the conveyor belt 1, as well as two walls longitudinal connecting the two upstream 3 and downstream 4 walls, which longitudinal walls extend parallel to the direction of displacement F.
  • the lower edges of the upstream 3 and longitudinal walls are flush with the upper strand 1a of the strip conveyor 1, possibly being provided with a seal 5 bearing on said upper strand 1a.
  • a suction box which is able to create an air flow inside the dispersion chamber 2 7, symbolized by arrows, used to disperse the fibers (not shown) inside said chamber 2 and project them onto the upper strand 1a.
  • an injection of air through the upper opening of the dispersion chamber can help the dispersion of fibers.
  • the box 6 extends, under the strand upper 1a, on a suction zone 9, which zone 9 occupies, in width, the width at least of the dispersion chamber 2 and in length a distance D which is greater than the length L of the dispersion chamber 2.
  • the suction conditions used in the box 6 are such that the suction speed - measured in the box 6 - in the downstream part 9a of the suction zone 9 is lower than the suction speed in the upstream part 9b of the zone suction 9.
  • the box 6 is a multi-stage box, comprising a first floor 10 which extends under a so-called main section of the area suction 9, this main section 9c extending in length over a distance 1 which is less than the length L of the suction zone 9 surmounted by the dispersion chamber 2.
  • this main section 9c extends from substantially the lower edge 11 of the upstream wall 3 of the chamber dispersion 2 (or slightly downstream thereof) to a distance d from plumb with the lower edge 12 of the downstream wall 4 of the dispersion chamber 2.
  • the suction speed V1 is generated at the first stage 10 and uniform over the entire length 1 of said stage 10.
  • the suction box 6 has a second stage 13 which covers the secondary section 9d of the suction zone, which goes beyond the main section 9c previously defined.
  • the conditions used are such that the speed suction gradually decreases over the entire length of the secondary section 9d from the entrance to the exit thereof, as illustrated in Figure 1 by the continuous decrease in arrows V2, symbolizing the suction speed in said section secondary 9d.
  • the secondary section 9d is divided into five sub-sections 9d 1 , 9d 2 , 9d 3 , 9d 4 , 9d 5 from upstream to downstream of said secondary section 9d.
  • the suction speed V3 is constant. This speed V3 decreases from one section to another from upstream to downstream of said secondary section 9d.
  • Each sub-section 9d 1 to 9d 5 corresponds to a stage 14 to 18 of the suction box 6.
  • the fourth exemplary embodiment which is illustrated in FIG. 4 is a combination of the second and third examples previously described, the suction speed V5 gradually decreasing in some stages 14, 16 and 18 while it remains constant in certain others 15, 17.
  • the suction box 6 has three stages, namely the first stage 10 which corresponds to the main section 9c of the suction zone 9 and two successive second stages 14 and 15 which correspond to the sub-sections 9d 1 and 9d 2 of the secondary section 9d of the suction zone 9.
  • This number of stages is not exclusive, and can be greater as in the example illustrated in FIG. 2, but it can also be two .
  • the fibers are ejected individually to inside the dispersion chamber 2, are dispersed by the flow of air over the entire horizontal section of said chamber 2 and are projected onto the upper strand 1 a of the conveyor belt 1. Because of the accumulation of fibers on the upper strand 1a during the movement of the conveyor belt 1, a nonwoven is thus formed 13 which is conveyed to the outside of the dispersion chamber 2 passing to the right of the downstream wall 4 of said chamber 2, which in the example illustrated is a plate.
  • the spacing e between the edge lower 12 of said downstream wall 4 and the upper strand 1a is determined so that this spacing is greater than the thickness of the nonwoven formed in the dispersion chamber 2, as it stands when it leaves said chamber 2.
  • This spacing e depends on the grammage of the nonwoven. It is preferably from 5 to 50 mm, for example of 30 mm.
  • the air flow that moves the fibers inside the chamber dispersion 2 is created in particular by the suction box 6, more precisely by the suction generated by the section portion suction 9 which is located to the right of the dispersion chamber 2.
  • Other complementary means could be implemented, for example example an air injection at the top of the dispersion chamber 2, in order to help the spotting of the fibers of the cylinder 8.
  • the nonwoven is somehow supported by the second stage 14 of the suction box 6 in which the speed suction V2 is lower than the speed V1 of the first stage.
  • This management takes place while the nonwoven 13 is still inside the dispersion chamber 2, over the distance d then then that the nonwoven 13 has come out of the dispersion chamber 2.
  • This outlet in charge which continues at the level of the second stage 14 of the box suction 6 allows that there are no disturbances caused by the passage of the nonwoven under the lower edge 12 of the downstream upright 4 of the dispersion chamber 2 since we observe substantially the same air flow regime on either side of this downstream amount 4.
  • FIG. 5 there is a pressure roller 20 which is perpendicular to the partition 21 which separates the two successive stages 14, 15 of the secondary section 9a.
  • This roller presser 20 is mounted transversely above the upper strand 1a of the conveyor belt 1, applying to the nonwoven 13.
  • the distance T between the vertical passing through the lower edge 12 of the wall downstream 4 and the vertical tangent to the rear of the roller 20 is, from preferably relatively small, preferably 10 to 30 mm.
  • the dispersion 2 has a length L of the order of 60 mm, that of the section main 9c of the order of 50 mm and that of the first stage 9d, of the secondary section of the order of 80 mm.
  • the distance T is of the order of 20 mm for a roller 20 having a diameter of the order of 100 mm.
  • the nonwoven is then taken care of by the suction created by the next second stage 15 of the suction box 6, of which the suction speed V3 is lower than the suction speed V2 of the second stage 14.
  • this support can be carried out successively with other second stages 16 to 18 until there is no longer any suction at all beyond the box 6.
  • This gradual reduction (by stages in the present example) of the suction in the secondary zone 9d allows there to be a gradual loosening of the fibers of the nonwoven 13, under the effect of said aspiration. This is what makes it possible to obtain the desired result, namely the production of a particularly homogeneous nonwoven, in good industrial conditions, at high speed.
  • the suction speed V1 at the main section 9c of the suction zone 9 was of the order of 30 to 90 m / s.
  • the suction speeds of the five second stages located at the secondary section 9d of the suction zone 9 were respectively equal to or of the order of 0.8 V, 0.6 V, 0.4 V and 0.2 V, knowing that V being the speed of the most upstream first stage and had a value itself less than V 1 , for example 0.8 V 1 .
  • the first stage at speed V1 of the suction box was equipped with its own fan, while for the five second stages, a single fan made it possible to obtain this gradual reduction in suction speed thanks to the use of sheets. perforated.
  • the present invention is however not limited to the modes of which have been described by way of non-exhaustive examples.
  • All appropriate means can be used to obtain the suction speeds in the suction box, whether from a single fan or a plurality of fans, and from additional elements capable of reducing the suction speed possibly gradually, from upstream to downstream of the suction area.
