Definitions

  • This invention relates to a production line for nonwoven textiles obtained by needling.
  • a needling nonwoven manufacturing line generally consists of the following machines: - a card - a blamire or spreader-lapper - a pre-needling machine - one or more needling machines - a winding device - subsequent stages of manufacturing such as pasting, latexing, etc.
  • the purpose of the card is to create, from individual fibers, a light, coherent but fragile veil.
  • the purpose of the blamire is to deposit this veil in several superimposed and progressively offset layers, so as to produce a mattress or a sheet of a higher surface weight.
  • the purpose of needling machines is to consolidate this mattress by interpenetration of fibers and layers. Planks filled with a large number of vertical needles regularly strike up and down the mattress of fibers parading horizontally below these needle planks. Fibers from the upper layers are drawn by the needles to the lower layers, and a felting effect follows which gives the mattress greater resistance, this resistance depending strongly on the penetration density of the needles in the sheet.
  • the reel receives the needled product and puts it in the form of rolls suitable for transport to the later stages of manufacture.
  • this ply undergoes changes in the distribution of the fibers.
  • volume density of the material increases as the needling progresses, in the sense that the thickness of the sheet is greatly reduced by the interpenetration of the fibers of the different layers.
  • V shape obtained at the end of the production line therefore constitutes a cause of loss of profitability of the process, which the producers obviously try to reduce to the minimum, without however being able to control it perfectly.
  • the object of the present invention is to provide producers with an additional and effective means for reducing material losses, by creating better sectional regularity of the product leaving the needling machines.
  • the method consists in artificially creating, by the card and the blamire, a tablecloth whose weight varies on the width approximately inversely with the distribution of weight which one would obtain at the exit of the needlepunchers in the traditional process.
  • FIG 1 there is shown a section of the output of a card 1, a machine well known in textile circles.
  • the last drum 2 is the painter who delivers the final web 3 from the card, this web being detached from the painter 2 by the beating comb 4.
  • This veil is deposited on a conveyor belt 5 which transports it to the blamere 6.
  • the latter by means of other conveyor belts 7 and following a circuit of which there are many variants in the industry, conducts the veil towards another conveyor belt 8 arranged under the conveyor belts 7 and whose direction of travel 11 (FIG. 2) is 90 degrees relative to that 10 of the conveyor belts 7.
  • the driving rollers 9 move alternately from the end A to the end B of the conveyor belt 8.
  • FIG. 2 shows how the layers are deposited on the conveyor belt 8.
  • the number of reciprocations performed by the cylinders 9 while the conveyor belt 8 advances from C to D is an integer, so that the edges of the successive layers coincide and that the sheet has an equal weight at all points.
  • the curve observed has a shape of the type shown in figure 3.3.
  • the object of the present invention is to restore at the outlet of the last needling machine a constant weight distribution over the width of the ply.
  • the frequency that we choose for the speed variation of the doffer is obviously the frequency of the reciprocating movement of the cylinders 9.
  • the weight of the veil which is deposited must be on the conveyor belt 8 is maximum.
  • the weight of the web which is deposited on the conveyor belt 8 must be minimum. Between these extreme positions the weight of the veil can vary according to any curve to be chosen according to experience; in particular this curve can be a straight line.
  • This delay constitutes an additional parameter of the system, which can be easily taken into account by using a computer 15 to regulate the speed of the comber 2 according to the position of the cylinders 9.
  • the computer 15 receives the information of the position of the cylinders 9 of the sensor 17, calculates the corresponding speed of the painter 2, but does not send the corresponding instruction to the motor control 19 of the painter only after the delay which has been determined. This period can be determined by calculation or experimentally.
  • the action of the pre-needling machine instead of creating a V-shaped deformation, reduces the amplitude of the counter-V curve, and at the exit of the pre-needling machine a weight curve is obtained such that shown in figure 4.2.
  • the action of the needling machine also reduces the amplitude of the initial counter-V, and a weight curve is obtained at its exit as indicated in Figure 4.3., Which is the goal of the producer of nonwoven , namely to obtain a product as flat as possible at the exit of the production line.
  • the movement of the cylinders 9 is carried out by a system comprising chains for translation, these chains being driven by chain wheels 18 themselves controlled by a DC motor 14.
  • the motor 14 is controlled by a computer 15, which calculates its speed and, as soon as the cylinders 9 have achieved the translational stroke necessary to achieve the desired ply width, commands it to brake in a very short time and to reverse its direction of rotation, therefore the direction displacement movement of the cylinders 9.
  • a sensor 16 placed in the center of the conveyor belt 8 gives the computer the midpoint G of the sheet (fig. 2).
  • the operator chooses the width of the GE or GF sheet on the computer on each side of this midpoint.
  • An incremental encoder 17 is placed on the chain wheel 18, an encoder which permanently provides the computer 15 with the indication of the position of the cylinders 9. Knowing that the midpoint G of the ply, given by the sensor 16, represents the point where the veil 12 deposited should be the heaviest, and that the extreme points E and F, calculated by the computer 15, represent the points where the veil should be the lightest, the computer can calculate at any time speed of the doffer 2 to obtain the desired sail weight. This requires that we have entered in the computer the value of the weight of the veil that we want in the center or at the ends and the curve of the weights that we want to follow.
  • the invention also covers all the other embodiments the aim of which would be to periodically vary the speed of the card doffer 2 in order to obtain at the outlet of the blamire 6 a ply whose weight is deliberately irregular, so as to counteract the 'effect of destruction of the regularity of the weight of the tablecloth normally created by needling machines or machines according to the blamire.
  • the invention also covers cases where the blamire is replaced by another machine intended to superimpose several layers of veil so as to produce a thicker sheet. We will call these machines “stacking machines”.
  • the invention also covers cases where the needling machines are replaced by other machines intended to consolidate the sheet or carry out any treatment on this sheet. We will call these machines “consolidation machines”.
