  • FIGS. 6A and 6B illustrate another embodiment of the textile material drive module
  • FIG. 7A and 7B illustrate yet another embodiment of the textile material drive module.
  • FIG. 1 schematically illustrates a circular type needling machine intended for needling a textile structure, or annular preform, produced from a wound strip, of fabric or nonwoven, of a textile material to be needled and provided with an automatic feeding device according to the invention.
  • This machine intended for needling textile structures 10 formed from a strip of a textile material to needling delivered continuously by supply means 12 conventionally comprises a needling table 14, forming a winding plate, on which goes come to rest this strip of textile material and which is movable vertically under the action of movement transmission means 16 as the strip unfolds.
  • Drive means 18 advantageously consisting of three conical rollers 20 each actuated by an independent geared motor group 22 and preferably arranged at 120 ° above this table, will then frictionally drive the rotation of this strip of textile material on the needling table.
  • the needling of the strip is carried out by a needling head
  • this needling head is driven in a vertical reciprocating movement by conventional displacement means 26.
  • Cutting means 28 (see FIG. 5) arranged upstream of the needling zone are also provided for cutting the strip once the final predetermined thickness for the textile structure has been obtained (sensors not shown make it possible to precisely control this thickness as and when the different layers are superimposed) .
  • Central control means 30 connected to the movement transmission means of the table 16, to the drive means of the textile structure 18, to the means of reciprocating movement of the head 26, and to the cutting means 28 make it possible to ensure the control and synchronization necessary to obtain a continuous needling process.
  • evacuation means 32 allow this structure to be pushed out of the needling table, for example towards a conveyor belt (not shown) with a view to its transfer to another station of the production line as a processing station thermal such as that illustrated by international patent application WO96 / 33295 and relating to densification in annular stacks.
  • the means 12 for supplying the material to be needled comprise a storage basket 40 containing a rolled up strip of textile material 42 and formed from a central barrel 44 with an axis of rotation C at the lower part of which (also called backplane 44a) is fixed a series of fins 46a-46f forming perforated receiving plate and intended, in particular during its transport, to support the strip wound around the central drum.
  • the storage basket is installed on the needling machine, in the same axis C of the needling table, at an upper frame 50 of this machine.
  • the openings of the tray are intended to be traversed by the conical rollers 48a-48f of an unwinding assembly advantageously driven by a belt and carrying out the extraction of the strip at the backplane (see figure 2).
  • the conical rollers for driving the unwinding assembly partially pass through the perforated receiving plate forming the bottom of this basket so that these rollers come into direct contact with the material. textile to unroll.
  • the unwinding of the strip results from the rotation on themselves of the conical rollers for driving the unwinding assembly, this rotation being obtained by friction from a crown 52 centered on rollers 54a, 54b, 54c integral with the chassis of the machine 50 and set in rotation about the axis C by a belt 56 driven by a motor 58 (see FIG. 1A) whose speed is advantageously regulated from the central control means 30, for example as a function of the average rotational speed of the preform.
  • the drive means of the rollers 48 cannot be limited to the aforementioned friction system alone, and individual drive of each roller by a motor-reduction unit controlled from the central control means 30, like that 22 used for the tapered rollers 20, is for example also possible.
  • the free end of the unrolled strip 42 is taken between one of the drive rollers 48b and a pressure roller 60, held against this drive roller by means of an elastic element acting in traction 62 (see FIG. 4), and it is guided (swallowed) between the fins 46b-46c under the receiving plate towards a helical chute 64, 66 (twist) bringing the textile material onto the needling table 14 at the level of a conical drive roller 20.
  • the initial setting of the end between the drive roller and the pressure roller is generally carried out manually when setting in place of the basket, the rest of the process then taking place automatically.
  • the helical chute integral with the chassis 50 of the machine is formed in two successive parts 64, 66 separated only by a space 68 forming a groove to allow the passage of the cutting means 28. All along this path, the strip is kept in contact with this chute by drive means preferably joined in two separate assemblies 70, 72 respectively disposed one 70 upstream the other 72 downstream of these cutting means 28.
  • Each drive assembly is preferably powered by an individual geared motor group 78, 80 controlled from the central control means 30. However, a common motorization is equally possible.
  • Each drive assembly 70, 72 comprises at least two, preferably three, rollers 74a, 74b, 74c; 76a, 76b, 76c each mounted on a support integral with the chassis 50 and connected together by a drive belt 82, 84 which drives the textile sheet along the twist.
  • the choice of the number of rollers to be used is essentially a function of the dimensions of the chute themselves linked to the overall size of the needling machine.
  • the rollers are arranged one behind the other so as to best match the helical shape of the chute.
  • Each geared motor group 78, 80 is connected to one 74a, 76a of the rollers of each drive assembly by means of a cardan link 86, 88.
  • a dancer roller 90 articulated on the frame 50 and intended to guarantee a regular tension on the unwound strip of textile material 42 after it has been cut by the cutting means and before it is taken up again at the needling table 14 by one of the conical drive rollers 20.
  • any slack in this unwound strip is eliminated and the needling rate can then be precisely controlled.
  • FIGS. 6A and 6B illustrate a second embodiment of the separate drive assemblies 70, 72 in which, to better conform to the shape of the twist 64, the drive belt 82, 84 is mounted on a plurality of inclined rollers 92a, 92b, 92c, 92d, 92e, 92f.
