Definitions

  • the present invention relates to a method for producing a sheet of fibers with non-uniform thickness profile.
  • the present invention also relates to a method for create a continuous textile product with a profile transversal non-uniform.
  • the present invention also relates to a device spreader spreader and a device for manufacturing a continuous textile product for the implementation of these processes.
  • the veil is deposited in segments tilted alternately in one direction and the other, which overlap.
  • the folds between successive segments are aligned along the lateral edges of the produced web.
  • Such a sheet generally has a thickness profile uniform throughout its width.
  • FR-A-2 234 395 teaches the speed relationships to be respected in the spreader for to control the thickness of the tablecloth.
  • the sheet may have a profile of variable thickness in varying the speed of the carriage which lays the veil in a variable point of the width of the exit carpet, by relative to the speed of the carpets that convey the veil to this cart. If in a given position of width of the tablecloth, the cart moves at a higher speed to that to which he unwinds the veil, the veil is stretched and this reduces the thickness of the web at this location. If, on the other hand, the speed of the carriage is lower than speed of unwinding, the veil is deposited in a form compressed which increases the thickness of the tablecloth at this location.
  • This method of profiling the tablecloth has certain limitations. Stretches and compressions of the veil do. can be positioned precisely because there is a distance between the point where the sail comes out of the carriage and the place where it is deposited on the exit conveyor. In addition, particularly with certain types of fiber, tensile or compressive stresses imposed on the sail tend to be transmitted to certain regions of the veil, just before or just after the zone for which specific traction or compression was desired. Finally, the traction or compression imposed on the sail does not may not without risks exceed certain limits.
  • DE-C-100 658 and DE-A-195 27 416 disclose processes in which two successive laps are performed. To prevent the longitudinal edges of the first tablecloth form transverse edges on the second web, said longitudinal edges are made bevel. For this, some of the folds between segments of the first topping are slightly shifted laterally towards inside the first tablecloth. The goal of this provision is obtaining a final textile product having a regular longitudinal profile. The product from second topping has a uniform transverse profile.
  • DE-A-42 34 354 describes a deposit of sails elementary elements with staggered edges, so as to elementary veils between them. This results in a thickness and a reduced surface weight, along the edges, which must be removed by a section designated by the reference "T", so that the product which is then needled has a uniform transverse profile.
  • the object of the present invention is to propose a process and a device to achieve more efficiently a web of fibers and a continuous textile product with a profile of thickness and / or uneven surface weight, in particular staggered, across the width of the web.
  • the method for producing a layer of fibers having a stepped profile in depositing on an exit conveyor of the sail segments successive transversals connected to each other by folds made alternately in one direction and the other by inversion of the transverse direction in which the veil is deposited, a process in which different locations of the conveyor width of exit some at least successive folds of the same direction, is characterized in that pleats positioned according to minus one line between the lateral edges of the tablecloth form a shoulder between two longitudinal zones of the tablecloth.
  • the method to create a continuous textile product with a profile cross-section of non-uniform thickness in which a layer of fibers by depositing on an exit conveyor of a crosslapper, transverse web segments successive connected to each other by folds made alternately in one direction and the other by inversion transverse direction in which the veil is deposited, while positioned in different locations exit conveyor width at least some of the folds successive ones of the same meaning, is characterized in that the non-uniform profile of the web is substantially preserved in transverse orientation of the continuous textile product until the end of a subsequent consolidation step.
  • the amplitude of a segment will be called the distance between the two folds delimiting this segment.
  • the successive segments can have different amplitude and do not all cover the same region of the width of the output conveyor.
  • the number overlapping layers of sail is not the same in all regions of the width of the web.
  • the fold position can be chosen with a relatively high accuracy, the profile of the resulting sheet respects clear and precise way the desired theoretical profile.
  • the invention is particularly suitable for to produce a sheet whose profile has at least one variation of relatively abrupt thickness.
  • the lapping spreader shown in perspective in the figure 1 includes a feed mat 1 which collects the veil of fibers 2 resulting for example from a not shown card and carries it in the enclosure 3 of the spreader, where the veil is folded into a sheet 4 coming out of the enclosure 3 by an exit conveyor 6.
  • the carpet feed 1 is driven at a speed that is typically a constant speed in the direction of the arrows 7 penetrating the fiber web 2 in the chamber 3, by means of an electric motor 8.
  • the output conveyor 6 is driven in the direction of the arrows 9 making out the layer 4 of the enclosure 3, by means of an electric motor 11.
  • the rotational speed of the motor 11 can be constant, or, alternatively, vary for example like this is described in FR-A-2 234 395.
  • the pinch zone 16 ends between a cylinder of guide 17 supporting the feed belt 1 and a guide cylinder 18 supporting the rear carpet 12, which define between them a slot of unwinding of the veil 2 opening down over the exit conveyor 6.
  • the longitudinal direction of the carpet 1 and the rear carpet 12 is perpendicular to the longitudinal direction of the output conveyor 6.
  • the reel slot 19 is therefore parallel to the direction longitudinal of the exit conveyor 6.
  • the circuit followed by the feed belt 1 and the back carpet 12 to the interior of the enclosure 3 is not represented in all because it can take any known form, for example, according to FR-A-2 234 395, EP-A-0 517 563, FR-A-2,553,102 etc ...
  • the two cylinders 17 and 18 defining the slot of 19 are carried by a topping carriage 21 which is only very schematically represented in FIG.
  • carriage 21 is coupled to a drive means 22 such an endless toothed belt bypassing two pulleys 23, 24.
  • One of the pulleys 23 is connected to the shaft of an electric drive motor 26 capable of operate in both directions, to be able to move the trolley 21 back and forth parallel to the direction transverse of the output conveyor 6 as illustrated arrows 27.
  • Two guide rails, of which only one 28 is shown in Figure 2 to simplify this, can be provided on both sides of mats 1 and 12 for support and guide the carriage 21 in its movement of and comes according to the arrows 27.
  • the carriage 21 may comprise rollers rolling in the 28. Any other appropriate means of guidance is possible.
  • the drive motor 26 of the topping carriage 21 is controlled by a control unit 29 itself connected or part of a programming desk 31 ( Figure 1).
  • the control unit 29 defines at every moment the speed of the motor 26, and therefore on the one hand the amplitude of the movement back and forth of the topping carriage 21 and on the other hand the laws of speed and acceleration of the carriage, in particular during slowdown, shutdown and re-acceleration in the opposite direction at each change of direction of the carriage 21.
  • the veil 2 follows between its entry into the enclosure 3 by means of the feed belt 1 and its exit through the unwinding slot 19, a path of variable geometry, which passes through an upper carriage (not shown).
  • the purpose of these provisions is to achieve inside the enclosure 3 a variable accumulation of sail 2, to make an adaptation between the location fixed where the veil 2 penetrates at constant speed into the machine by the feed belt 1 and the location variable where the slot 19 unwinds the veil 2.
  • This adaptation can be achieved by a simple mechanical coupling between the two carriages as described in FR-A-2,553,102.
  • more sophisticated commands described in particular in FR-A-2 234 395 make it possible to establish a speed report variable between the two carriages to control the thickness deposition of the veil 2 on the output conveyor 6 despite the inevitable variations in the absolute speed of the trolley of 21.
  • mechanical coupling between the two trolleys is not planned.
  • the unit of control 29 has a link 32 with an engine drive the upper carriage to drive the truck superior in a coordinated manner with the trolley of 21.
  • the control unit 29 is connected to the motor 13 to control the speed of the rear carpet 12 of way it equals the speed of carpet 1 at all instant in the pinch zone 16.
  • the FR-A-2 553 102 shows however that in certain configurations of machine where the pinch zone makes a turn around of a guide cylinder, both mats can be driven by the same engine coupled to this cylinder and suitably speed-driven in correlation with the back and forth movements of the lapper carriage 21.
  • a segment 2b is in formation, it started by a fold 2ab which separates it from segment 2a which has just been finished, and it will end with a 2bc fold in the other meaning, ie to the left, which will separate him from segment 2c next.
  • the folds are parallel to the longitudinal direction of the output conveyor 6 and the web 4.
  • the folds of the same meaning that succeed each other along the tablecloth 4, instead of being all superimposed along a corresponding lateral edge of the tablecloth as the state of the art taught, are at otherwise offset laterally with respect to other.
  • the folds 2ab to left of the tablecloth and 2da to the right of the tablecloth are adjacent to the respective lateral edge of the web 4, while that the folds 2cd and 2bc are shifted towards the inside of the tablecloth 4.
  • the topping is performed in a repeating pattern comprising the four aforementioned segments 2a, 2b, 2c and 2d defined by the folds 2da, 2ab, 2bc and 2cd which delimit them.
  • the repetitive execution of this lapping pattern produces, in the example shown, four rows of folds, corresponding respectively to folds 2ab and 2da forming the edges side of the tablecloth 4, and two rows 2bc and 2cd located at a certain distance from the longitudinal edges of the tablecloth.
  • a central zone 4a located between the folds 2bc and 2cd the thickness of the sheet is maximum because all segments are present.
  • Figure 3 shows the folding diagram of the sail 2 on the output conveyor 6.
  • Figure 4 shows the profile of web obtained, with a shoulder 4ab and 4ac between the central zone 4a and each lateral band 4b, 4c.
  • the shoulders 4ab, 4ac form along the folds 2cd and 2bc respectively.
  • the thickness variations of the tablecloth correspond to variations in surface weight corresponding along the transverse profile of the web.
  • a programming step is added during start-up preparations of the spreader by means of the programming panel 31.
  • This step is to ask the user to define the sequence of races that the lapper carriage must perform to produce the topping pattern.
  • the user may have to define for example the number of market reversals of trolley (number of pattern folds) and the position of each of these reversals (position of the folds of the pattern) relative to the transverse dimension of the conveyor of 6. Taking into account such instructions by the spreader and in particular by the control unit 29 is within the reach of the skilled person since the spreaders of the trade are able to work in different tablecloth widths.
  • the lateral edges of the veil 2 do not form any variation in thickness along the sheet 4.
  • the user chooses the speed of the output conveyor 6 by displaying the choice of the value "n".
  • n 4
  • the spreader executes four lapping patterns while the output conveyor 6 advances the web 4 on the distance L.
  • each pattern includes four segments it there is therefore, in every point of the length of the sheet, sixteen sail thicknesses in the central zone 4a and, by therefore, only eight thicknesses in each band lateral 4b, 4c.
  • each pattern of topping includes a segment (2a) extending over the entire width of the web, a segment (2b) covering only the central zones 4a and one of the lateral bands 4b, a segment (2c) covering only the central zone 4a, and a segment (2d) covering only the central zone 4a and the other sideband 4b.
  • each tablecloth pattern comprises six segments 2a-2f, among which segments 2f and 2a cover the central zone 4a and one of the sidebands 4b; two other segments successive 2c and 2d cover the central zone 4a and the other sideband 4b, while segments 2b and 2e do not cover as the central area 4a.
  • the profile obtained is similar to that of Figures 3 and 4, except that the thickness of the lateral bands 4b and 4c is equal to third of the thickness of the central band 4a.
  • each pattern of topping corresponds to two successive layering patterns of FIG. 3 with the only difference that fold 2cd is moved from the shoulder 4ab to the lateral edge of the tablecloth.
  • the segments 2c and 2d which are connected by this fold are lengthened correspondingly.
  • the fold 2gh corresponding to the other fold 2cd of the two patterns of successive layering of Figure 3 still extends along of the shoulder 4ab.
  • the tablecloth is thus made asymmetrical shown in Figure 8, where the band 4b extending between the folds 2cd and 2gh is a one and a half times thicker than the other sideband 4b, which is, as before, half as thick as central area 4a.
  • FIG. 9 shows that it is possible avoid having to make segments covering only the thicker central area 4a.
  • the tablecloth pattern is consisting of pairs of segments 2b, 2c; 2nd, 2f corresponding to a round-trip of the veil between one of the side edges of the web and shoulder 4ac respectively 4ab furthest from this edge. These pairs are separated by segments 2a; 2d covering the whole width of the tablecloth.
  • Figures 9 and 10 also shows that the 4ab and 4ac shoulders layout is not necessarily symmetrical with respect to the longitudinal axis of the tablecloth.
  • all the folds in one of the senses 2ab, 2cd are adjacent to a first edge lateral of the tablecloth.
  • One 2bc folds in the other direction is adjacent to the other side edge of the web.
  • the other fold 2da in said other direction coincides with a shoulder 4 of formed by the web between a lateral extra thickness 4d, and a thinner zone 4e of the web.
  • the extra thickness 4d is adjacent to the first side edge of the web between the folds 2ab and 2cd on one side, and the folds 2bc on the other.
  • FIG. 13 and 14 shows that it is possible to realize a thickness 4d and respectively 4f along each side edge of the web, from other of a central zone 4th less thick.
  • the reason for tablecloth is composed of two half-motifs each of which is the same as in Figure 9 except that segments 2b, 2c, 2h and 2i covering only a portion of the width of the web, from one of the side edges thereof, have a amplitude too small for them to overlap segments 2e, 2f, 2k and 21 covering only part of the width of the web from the other side edge thereof. he there is therefore in the central zone 4e only segments 2a, 2d, 2g, 2j covering the entire width of the web.
  • the sideband 4d is delimited by a Shoulder 4de relatively abrupt because the folds 2bc and 2hi that form it in every tablecloth pattern are exactly Bunk.
  • the shoulder 4ef separating the other lateral band 4f of the 4th central zone is softened as it there is a slight lateral shift "d" between folds 2ef and 2kl which form this shoulder.
  • the two half-patterns of the Figure 13 are identical.
  • the excess thicknesses 4d and 4f are offset towards the inside of the sheet by corresponding shift of segments 2b and 2c as well as folds 2ab, 2bc and 2cd which delimit them.
  • segments 2e and 2f and the folds 2de, 2ef and 2fg which delimit them.
  • the layering pattern includes folds 2gh, 2hi, 2ij and 2ja adjacent to the side edges of the web, as well as segments connecting these folds together and with the rest of the tablecloth pattern.
  • the profile obtained is the one represented in FIG. 16, with weak sidebands 4b and 4c.
  • Figures 17 and 18 corresponds to another embodiment to form two ribs 4d and 4f each located at a certain distance from the longitudinal edge of the web.
  • the reason for topping is a half pattern of Figures 13 and 14 but in which segment 2a is replaced by three segments 2g, 2h and 2a. Segment 2h has a terminal zone which overlaps the 2nd and 2nd segments and another area terminal that overlaps segments 2b and 2c to form the extra thicknesses 4d and 4e respectively, which can therefore have a very small width for the same reasons as the excess thickness 4a of Figures 9 and 10.
  • Each end of the segment 2h is connected with the edge opposite side of the sheet by a fold 2gh and respectively 2ha and a segment 2g and 2a respectively.
  • Folds 2gh and 2ha form the outer longitudinal edge of the ribs 4d. and respectively 4f, while the folds 2bc and 2ef define the inner longitudinal edges of said ribs.
  • Figures 19 and 20 is identical to that of Figures 17 and 18 except that in each pattern of topping, each pair of segments 2b, 2c; 2nd, 2f does not covering only one lateral band and an adjacent rib 4b and 4d; 4f and 4c is replaced by two superimposed pairs 2b, 2c and 2j, 2k; 2nd, 2f and 21, 2m. This has the effect of make the sidebands 4b and 4c thicker than the central area 4a.
  • Figure 21 illustrates that at the exit of the crosslapper 41, which may be that of FIGS. 2, the sheet 4 with in the example three zones 4a, 4b, 4c separated by two shoulders 4ab and 4ac is guided by appropriate means symbolized by reference 44, to a consolidation machine 42, typically a needling machine.
  • the means 44 are at least partly constituted by the conveyor 6 of the crosslapper 41.
  • the non-uniform profile staged produced by the spreader 41 is still in transverse orientation when passing through the needling 42. This means in particular that the sheet 4 does not undergo any intermediate treatment such as second topping that would change this orientation.
  • the product textile moves in a straight line from the exit of the crosslapper 41 at the entrance to the needling machine 42.
  • the textile product obtained has a profile in which found essentially the resulting profile of the glaze, with in the example three zones of continuous thickness 43a, 43b, 43c separated by two shoulders 43ab and 43ac, although that the needling has considerably compacted the profile.
  • the invention is not limited to examples described and represented, the purpose of which is not to make an exhaustive list of possibilities but to show by which means the relative thicknesses, the symmetries and dissymmetries, the number of thickness ranges different, and the mode of transition between two beaches of different thickness, can vary almost to infinity by the methods and devices according to the invention.
  • the invention is compatible with any provision varying the thickness, especially the degree positive or negative stretching of the veil deposited on the output conveyor. This allows to combine the variations thickness more or less abrupt due to the invention with more gradual variations between different points of the width of the same zone of thickness defined by the invention.
