Definitions

  • the present invention relates to the general field of circular needling tables for the production of needle-punched textile structures from an annular fiber preform.
  • a circular needling table generally comprises a horizontal annular plate on which is placed an annular fiber preform, drive means (usually frictional) in rotation of the fibrous preform around the axis of the plate, and a device needling head having a needling head extending over an angular sector of the plate and driven in relative vertical movement with respect to the plate.
  • drive means usually frictional
  • a device needling head having a needling head extending over an angular sector of the plate and driven in relative vertical movement with respect to the plate.
  • the main object of the present invention is thus to overcome such disadvantages by proposing a needling table which makes it possible to obtain a textile structure with perfectly sharp edges and to prevent the material from creeping.
  • a circular needling table of a textile structure formed from an annular fiber preform comprising a horizontal annular plate on which is intended to be arranged an annular fiber preform, drive means rotation of the fibrous preform around the axis of the plate, and a needling device having a needling head extending over an angular sector of the plate and animated by a relative vertical movement with respect to the plate, and comprising in addition, according to the invention, means for guiding the fiber preform under the needling head.
  • the needling table comprises guide members of the fibrous preform which are integral with a stripper plate interposed between the needling head and the plate.
  • the guide members may be formed by pins extending vertically from the stripper to the plate and positioned angularly so as to form an outer and inner guide of the fiber preform.
  • the plate then advantageously comprises holes located each facing one of the guide pins of the stripper.
  • the guide members may be formed by inner and outer walls extending vertically from the stripper to the tray.
  • the needling table comprises inner and outer vertical walls for guiding the fibrous web which are integral with the plate and which are positioned angularly so as to form an outer and inner guide of the fiber preform.
  • the needling table may further comprise a stripper plate interposed between the needling head and the plate, the outer guide wall of the fiber preform or the stripper then having vertical notches to allow the lowering of the stripper.
  • a circular needling table 10 according to a first embodiment of the invention is very schematically represented on the Figures 1 and 2 .
  • the invention is applicable to any circular needling process in which annular textile layers (or layers) are stacked and needled on a tray to form a needled fibrous preform of annular shape.
  • These layers may be previously formed by juxtaposed rings or ring sectors cut from a non-woven fabric or fabric of unidirectional or multidirectional fibers. They can also be formed by coils wound flat from a feeding device such as that described in the patent application.
  • WO 02/088449 or by turns formed to from deformed braids, or by turns formed from a deformable two-dimensional texture (braid or helical fabric).
  • the fibrous annular preform 12 to needling rests directly on a horizontal annular plate 14 of the needling table. It is rotated about a vertical axis 16 by a set of conical rollers 18a, 18b kept in permanent contact with the annular preform.
  • This assembly may comprise two conical rollers spaced 120 ° and each actuated by an independent geared motor 20a, 20b.
  • a common drive coupled with a suitable kinematics could also be considered.
  • the annular preform 12 thus rotated passes a needling device 22 comprising in particular a needling head 24 which overhangs a predetermined angular sector of the horizontal plate 14.
  • This needling head is driven in a reciprocating vertical movement relative to to the plate 14 by means of a suitable drive device 26 (for example of the crank-handle type).
  • the needling head 24 carries a specified number of needles 28 which are provided with barbs, hooks or forks to take fibers from the stacked layers of the annular preform and transfer them therethrough as they enter the preform .
  • the plate 14 of the needling table comprises a series of vertical perforations 30 located facing the needles 28 of the needling head for the passage thereof during the needling of the first layers of the preform annular. Furthermore, at each needling of a new layer, the plate of the needling table is moved vertically, by means of motor means 32 adequate, a determined pitch of descent corresponding to the thickness of a layer needled.
  • the needling device 22 also comprises a stripper plate 34 which is interposed between the needling head 22 and the plate 14.
  • This stripper has the function of ensuring a maintenance of the annular preform portion located under the needling head during the passage of the needles 28 therethrough.
  • the stripper 34 is able to be moved vertically with respect to the plate 14, by example by means of the drive device 26 of the needling head. This movement is synchronized with that of the needling head so that the stripper 34 is lowered and applied against the annular preform portion located under the needling head during the passage of the needles (case of the figure 4 ).
  • the stripper comprises a series of perforations 36 passing through it from one side to another and located opposite the needles 28 of the needling head for the passage thereof during the needling of the strata of the annular preform.
  • the stripper 34 comprises guide pins 38a, 38b extending vertically from its inner face to the plate 14 and angularly positioned to form an outer and inner guide of the annular preform.
  • the stripper 34 comprises for example four inner pins 38a defining an arc of a circle centered on the vertical axis 16 of the inner side and six outer pins 38b defining an arc of a circle centered on the axis 16 of the outer side.
  • These inner and outer pins delimit between them a path for the passage of the annular preform under the needling head.
  • the plate 14 comprises a series of holes 40 each located opposite one of the guide pins 38a, 38b of the stripper 34 for the passage thereof during the lowering of the stripper.
  • the guide pins 38a, 38b are made of metal and are welded to the stripper also metal.
  • the spacing between the inner pins and the outer pins is possible to adjust the spacing between the inner pins and the outer pins to adapt to the dimensions of the preform by changing stripper.
  • FIGS. 5A-5B , 6A-6B represent a second embodiment of these guide means.
  • the various referenced elements of the needling table are identical to those described in connection with the first embodiment.
  • the horizontal plate 14 of the needling table here comprises vertical guide walls of the annular preform which are positioned angularly so as to form an outer and inner guide of the preform.
  • the plate carries an outer horizontal plate 42a at the end of which is mounted an outer guide wall 44a which extends vertically from the outer plate to the needling head 24.
  • the plate also carries an inner horizontal plate 42b at the end of which is mounted an inner guide wall 44b which extends vertically from the inner plate to the needling head.
  • These walls 44a, 44b form an outer guide and an inner guide for the annular preform portion positioned under the needling head.
  • these guide walls are fixed relative to the horizontal plate 14.
  • the outer guide wall 44a may comprise vertical notches 46 to allow the passage of the edges of the plate forming the stripper ( Figures 5A-5B , 6A-6B ).
  • the edges of the plate forming the stripper may comprise such vertical notches 46 'to allow its lowering.
  • the figure 8 represents yet another variant embodiment of a circular needling table in which the vertical walls 44'a, 44'b for guiding the preform under the needling head 24 are integral with the stripper 34 (rather than the plate) these walls extend vertically from the plate forming the stripper to the plate 14 of the table. Furthermore, recesses 48 of complementary shape to these guide walls 44'a, 44'b are formed in the plate facing the walls to allow the lowering of the stripper.
