Definitions
- the present invention relates to a process for producing a web of fibers with a profile of non-uniform thickness.
- the present invention also relates to a method for producing a continuous textile product having a non-uniform transverse profile.
- the present invention also relates to a lapping spreader device and a device for manufacturing a continuous textile product for the implementation of these methods.
- the veil is deposited in segments inclined alternately in one direction and in the other, which overlap.
- the folds between successive segments are aligned along the lateral edges of the sheet produced.
- Such a sheet generally has a profile of uniform thickness over its entire width.
- FR-A-2 234 395 teaches the speed relationships to be observed in the spreader to control the thickness of the web.
- the tablecloth may have a profile of variable thickness by varying the speed of the carriage which deposits the veil at a variable point of the width of the output conveyor, relative to the speed of the conveyors who bring the veil to this carriage. If in a given position ⁇ e the width of the web, the carriage moves at a speed higher than that at which it unwinds the web, the web is stretched and this reduces the thickness of the web at this location. If, on the contrary, the speed of the carriage is lower than the speed of unwinding, the web is deposited in a compressed form which increases the thickness of the sheet at this location.
- This method of profiling the sheet has certain limitations. Stretching and compressing the veil cannot be positioned precisely because there is a distance between where the veil exits the carriage and the place where it is deposited on the exit conveyor. In addition, in particular with certain types of fibers, the tensile or compressive stresses imposed on the veil tend to be transmitted to certain regions of the veil, deposited just before or just after the zone for which a determined traction or compression was desired. Finally, the traction or compression imposed on the veil cannot without risks exceed certain limits.
- DE-C-100 658 and DE-A-195 27 416 describe procedures in which two successive toppings are carried out.
- said longitudinal edges are produced in a bevel.
- some of the folds between segments of the first layer are slightly offset laterally towards the inside of the first layer.
- the purpose of this arrangement is to obtain a final textile product having a regular longitudinal profile.
- the product from the second coating has a uniform transverse profile.
- DE-A-42 34 354 describes a deposit of elementary sails with offset edges, so as to nest the elementary sails together. This results in a reduced thickness and a surface weight, along the edges, which must be eliminated by a cut designated by the reference "T", so that the product which is then sharpened has a uniform transverse profile.
- the object of the present invention is to provide a method and a device for more efficiently producing a sheet of fibers and a continuous textile product with a profile of non-uniform thickness and / or surface weight, in particular floor, over the width of the tablecloth.
- the method for producing a sheet of fibers having a stepped profile by depositing on an outlet conveyor successive transverse web segments connected to each other by pls produced alternately in one direction and in the other by reversing the transverse direction in which the veil is deposited proceeds in which are positioned in es different from the width of the outlet conveyor at least some successive folds of the same direction, is characterized in that folds positioned according to at at least one line located between the lateral edges of the sheet forms a shoulder between two longitudinal zones of the sheet.
- the method for producing a continuous textile product having a transverse profile of non-uniform thickness in which a sheet of fibers is formed by depositing on an outlet conveyor of a spreader-lapper, successive transverse web segments connected to each other by folds made alternately in one direction and in the other by reversing the transverse direction in which the web is deposited, while positioning at locations different from the width of the conveyor output at least some of the successive folds of the same direction, 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 distance between the two folds delimiting this segment will be called the "amplitude" of a segment.
- the successive segments can have a different amplitude and do not all cover the same region of the width of the outlet conveyor.
- the number of overlapping web thicknesses is not the same in all regions of the width of the sheet.
- the invention is particularly suitable for producing a ply whose profile has at least a relatively abrupt thickness variation.
- the lapping spreader device comprising:
- the profiling means comprise means for positioning at locations different from the width of the conveyor output at least some of the reversals of successive direction of travel of the carriage from the same direction of travel of the carriage, so as to define over the width of the sheet at least two zones of different thickness separated by at least one shoulder.
- the device for manufacturing a continuous textile product comprising:
- 1 spreader-lapper comprising: - an output conveyor;
- the guide means being arranged so that the transverse profile of the sheet leaving the spreader-lapper is found in a transverse position in the path through the consolidation machine , is characterized in that the profiling means comprise means for positioning, at locations different from the width of the outlet conveyor, at least certain successive reversals of the direction of travel of the carriage from the same direction of travel of the carriage.
- FIG. 1 is a perspective view of a lapper spreader according to the invention.
- FIG. 2 is a partial schematic view of the topping carriage and the outlet conveyor
- FIG. 3 is a schematic sectional view along III-III of Figure 2;
- FIG. 4 is a schematic view showing the sheet profile obtained with the covering pattern illustrated in Figure 3;
- the feed belt 1 is driven at a speed which is typically a constant speed in the direction of the arrows 7 causing the web of fibers to penetrate 2 in the enclosure 3, by means of an electric motor 8.
- the outlet conveyor 6 is driven in the direction of the arrows 9 causing the sheet 4 to come out of the enclosure 3, by means of an electric motor 11.
- the speed of rotation of the motor 11 can be constant, or, as a variant, vary for example as described in FR-A-2 234 395.
- the nip zone 16 ends between a guide cylinder 17 supporting the feed belt 1 and a guide cylinder 18 supporting the rear belt 12, which define between them a slot for unwinding the web 2 opening towards the bottom above the output conveyor 6.
- the longitudinal direction of the feed belt 1 and the rear belt 12 is perpendicular to the longitudinal direction of the output conveyor 6.
- the unwinding slot 19 is therefore parallel to the longitudinal direction of the output conveyor 6.
- the circuit followed by the feed conveyor 1 and the rear conveyor 12 inside the enclosure 3 is not shown in its entirety because it can take any known form, for example from FR-A-2 234 395, EP-A-0 517 563, FR-A-2 553 102 etc ...
- the two cylinders 17 and 18 defining the unwinding slot 19 are carried by a lapping carriage 21 which is only very schematically shown in FIG. 2.
- the carriage 21 is coupled to a drive means 22 such as a belt endless toothed bypassing two deflection pulleys 23, 24.
- One 23 of the pulleys is connected to the shaft of an electric drive motor 26 capable of operating in both directions, in order to be able to move the carriage 21 back and forth comes parallel to the transverse direction of the output conveyor 6 as illustrated by the arrows 27.
- Two guide rails, only one of which 28 is shown in FIG. 2 to simplify it, can be provided on either side of the belt 1 and 12 for supporting and guiding the carriage 21 in its reciprocating movement according to the arrows 27.
- the carriage 21 may include rollers rolling in the rails 28. Any other suitable guide means is envisaged geable.
- the motor 26 for driving the lapping carriage 21 is controlled by a control unit 29 itself connected or forming part of a programming console 31 (FIG. 1).
- the control unit 29 defines the speed of the motor 26 at all times, and therefore on the one hand the amplitude of the back and forth movement of the lapping carriage 21 and on the other hand the laws of speed and acceleration of the carriage, in particular during slowing down, stopping and re-acceleration in the opposite direction each time the direction of carriage 21 changes.
- the one- ci carries other cylinders supporting the two belts 1 and 12, and it is actuated back and forth parallel to the transverse direction of the output conveyor 6, therefore parallel to the back and forth movement of the lapping carriage '21.
- the purpose of these provisions is to achieve inside the enclosure 3 a variable accumulation of web 2, to achieve an adaptation between the fixed location where the web 2 enters the machine at constant speed through the feed belt 1 and the variable location where the slot 19 unwinds the web 2.
- This adaptation can be achieved by a simple mechanical coupling between the two carriages as described in FR-A-2 553 102.
- control unit 29 has a link 32 with a drive motor of the upper carriage to drive the upper carriage in a coordinated manner with the lapping carriage 21.
- control unit 29 is connected to the motor 13 to control the speed of the rear belt 12 so that it is equal to the speed of the belt 1 at all times in the pinch zone 16.
- the FR-A-2 553 102 shows however that in certain configurations machine where the pinch zone .makes a turn around a guide cylinder, the two belts can be driven by the same motor coupled to this cylinder and suitably controlled in speed in correlation with the back and forth movements of the lapper carriage 21.
- the combined action of the back and forth movement of the lapping carriage 21, of movement of the belts 1 and 12, and of advancement of the outlet conveyor 6 according to arrow 9, causes the deposition of the web 2 on the outlet conveyor 6 according to a zigzag formed of successive segments designated by the references 2a, 2b, 2c, 2d in the example of FIGS. 1 to 4, each limited by a fold in one direction and a fold in the other direction.
- the segments extend transversely on the output conveyor, however making an angle different from 90 ° with respect to the longitudinal direction of the output conveyor 6.
- These successive segments which overlap obliquely with respect to each other form the sheet 4
- Such a sheet is generally intended for a subsequent consolidation treatment, such as a needling treatment (not shown).
- a segment 2b is in formation, it started with a fold 2ab which separates it from the segment 2a which has just been finished, and it will end with a fold 2bc in the other direction, c 'is to say to the left, that will separate it from the following segment 2c.
- folds 2cd in the same direction as the folds 2ab, and separating the segments 2c from the segments 2d, and folds 2da, in the same direction as the folds 2bc, and separating the segments 2d from the segments 2a.
- the folds are parallel to the longitudinal direction of the outlet conveyor 6 and of the sheet 4.
- the folds of the same direction which follow one another along the ply 4 are instead offset laterally with respect to each other.
- the folds 2ab to the left of the tablecloth and 2da to the right of the tablecloth are adjacent to the respective lateral edge of the tablecloth 4, while the folds 2cd and 2bc are shifted towards the interior of the tablecloth 4.
- the coating is carried out according to a repeating pattern comprising the aforementioned four segments 2a, 2b, 2c and 2d defined by the folds 2da, 2ab, 2bc and 2cd which delimit them.
- This covering pattern produces, in the example shown, four rows of folds, corresponding respectively to the folds 2ab and 2da forming the lateral edges of the sheet 4, and two rows 2bc and 2cd situated at a certain distance from the longitudinal edges of the web.
- a central zone 4a located between the folds 2bc and 2cd the thickness of the sheet is maximum because all the segments are present.
- FIG. 3 shows the folding diagram of the web 2 on the outlet conveyor 6.
- FIG. 4 shows the sheet profile obtained, with a shoulder 4ab and 4ac between the central zone 4a and each lateral strip 4b, 4c.
- the shoulders 4ab, 4ac are formed along the folds 2cd and 2bc respectively.
- the sharpness with which the shoulders 4ab, 4ac appear is exaggerated in FIG. 4, especially as long as the ply 4 has not undergone a consolidation and compacting treatment such as the needling.
- the variations in thickness of the ply correspond to variations in corresponding surface weight along the transverse profile of the ply.
- a programming step is added during preparations for putting the spreader into operation by means of the programming console 31.
- This step consists in asking the user define the sequence of strokes that the lapper carriage must perform to produce the lapping pattern.
- the user may have to define, for example, the number of trolley reversals (number of folds of the pattern) and the position of each of these reversals (ply position of the pattern) relative to the transverse dimension of the conveyor. output 6.
- the taking into account of such instructions by the spreader and in particular by the control unit 29 is within the reach of those skilled in the art since the trade spreaders are capable of working in different widths of ply.
- each pattern comprises four segments there are therefore, at any point of the length of the sheet, sixteen thicknesses of web in the central zone 4a and, consequently, only eight thicknesses in each lateral strip 4b, 4c.
- each covering pattern comprises a segment (2a) extending over the entire width of the sheet, a segment (2b) covering only the central zones 4a and one of the side bands. 4b, a segment (2c) covering only the central area 4a, and a segment (2d) covering only the central area 4a and the other side strip 4b.
- each coating pattern comprises six segments 2a-2f, among which segments 2f and 2a cover the central area 4a and one of the side bands 4b; two other successive segments 2c and 2d cover the central zone 4a and the other lateral strip 4b, while the segments 2b and 2e only cover the central zone 4a.
- the profile obtained is similar to that of FIGS. 3 and 4, except that the thickness of the lateral strips 4b and 4c is equal to one third of the thickness of the central strip 4a.
- each layering pattern corresponds to two successive layering patterns of Figure 3 with the only difference that the fold 2cd is moved from the shoulder 4ab to the side edge of the ply.
- the segments 2c and 2d which are connected by this fold are elongated correspondingly.
- the fold 2gh corresponding to the other fold 2cd of the two successive topping patterns of FIG. 3 always extends along the shoulder 4ab. This produces the asymmetrical sheet shown in Figure 8, where the side strip 4b extending between the folds 2cd and 2gh is one and a half times thicker than the other side strip 4b, which is, as before, twice less thicker than the central area 4a.
- FIGS. 9 and 10 shows that it is possible to avoid having to produce segments covering only the thicker central zone 4a.
- the topping pattern consists of pairs of segments 2b, 2c; 2e, 2f corresponding to a round trip of the veil between one of the lateral edges of the ply and one shoulder 4ac respectively 4ab furthest from this edge. These pairs are separated by segments 2a; 2d covering the entire width of the tablecloth. It is thus possible to make an overthickness 4a having a very reduced width without the lapping carriage having to at any time carry out such a reduced stroke between two reversals of its direction of travel. Such a reduced stroke of the lapping carriage could cause anomalies in the deposition of the web 2.
- FIGS. 9 and 10 also shows that the arrangement of the shoulders 4ab and 4ac is not necessarily symmetrical with respect to the longitudinal axis of the ply.
- all the folds in one of the directions 2ab, 2cd are adjacent to a first lateral edge of the ply.
- One 2bc of the folds in the other direction is adjacent to the other lateral edge of the sheet.
- the other fold 2da in said other direction coincides with a shoulder 4de formed by the ply between a lateral extra thickness 4d, and a thinner zone 4e of the ply.
- the extra thickness 4d is adjacent to the first lateral edge of the ply between the folds 2ab and 2cd on one side, and the folds 2bc on the other.
- the example in FIGS. 13 and 14 shows that it is possible to make an additional thickness 4d and respectively 4f along each lateral edge of the ply, on either side of a thinner central zone 4e.
- the topping pattern is composed of two half-patterns, each of which is the same as in FIG.
- the lateral strip 4d is delimited by a relatively abrupt shoulder 4de because the folds 2bc and 2h ⁇ which form it in each coating pattern are exactly superimposed.
- the shoulder 4ef separating the other lateral strip 4f from the central zone 4e is softened because there is a slight lateral offset "d" between the folds 2ef and 2kl which form this shoulder.
- the two coating half-patterns in FIG. 13 are identical.
- the extra thicknesses 4d and 4f are offset towards the inside of the ply by corresponding offset of the segments 2b and 2c as well as folds 2ab, 2bc and 2cd which delimit them.
- the topping pattern includes 2gh, 2h ⁇ , 2 ⁇ j and 2ja folds adjacent to the side edges of the tablecloth, as well as segments connecting these folds together and with the rest of the topping pattern. The profile obtained is that shown in FIG.
- FIGS. 17 and 18 corresponds to another embodiment for forming two longitudinal ribs 4d and 4f each located at a certain distance from the longitudinal edge of the ply.
- the coating pattern corresponds to a half-pattern in FIGS. 13 and 14 but in which the segment 2a is replaced by three segments 2g, 2h and 2a.
- the segment 2h has a terminal zone which overlaps the segments 2e and 2f and another terminal zone which overlaps the 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 FIGS. 9 and 10.
- Each end of the segment 2h is connected with the opposite lateral edge of the sheet by a fold 2gh and respectively 2ha and a segment 2g and respectively 2a.
- the folds 2gh and 2ha form the outer longitudinal edge of the ribs 4d and 4f respectively, while the folds 2bc and 2ef define the inner longitudinal edges of said ribs.
- FIGS. 19 and 20 is identical to that of FIGS. 17 and 18 except that, in each covering pattern, each pair of segments 2b, 2c; 2e, 2f covering only one side strip and an adjacent rib 4b and 4d; 4f and 4c is replaced by two superimposed pairs 2b, 2c and 2j, 2k; 2e, 2f and 21, 2m. This has the effect of making the lateral bands 4b and 4c thicker than the central zone 4a.
- FIG. 21 illustrates that at the outlet of the spreader-lapper 41, which may be that of FIGS. 1 and 2, the ply 4 with in the example three zones 4a, 4b, 4c separated by two shoulders 4ab and 4ac is guided by appropriate means symbolized by the reference 44, to a consolidation machine 42, typically a needling machine.
- the means 44 are at least partly formed by the conveyor 6 of the spreader-lapper 41.
- the non-uniform stage profile produced by the spreader 41 is still in transverse orientation when passing through the needling machine 42.
- the ply 4 does not undergo an intermediate treatment such as a second ply which would change this orientation.
- the textile product moves in a straight line from the outlet of the spreader 41 to the entry into the needling machine 42.
- Intermediate treatments between the spreader 41 and the needling machine 42 are not excluded: it may be for example a pre-needling, an intermediate storage, etc.
- it is important that the transverse profile of the product entering the needling machine 42 retains the trace of the transverse profiling produced by the spreader-lapper 41.
- the textile product obtained has a profile in which the profile resulting from lapping is essentially found, with in the example three zones of continuous thickness 43a,
- the invention is not limited to the examples described and shown, the aim of which is not to make an exhaustive list of possibilities, but to show by what means the relative thicknesses, the symmetries and asymmetries, the number of ranges of different thicknesses, and the mode of transition between two ranges of different thickness, can vary almost infinitely by the methods and devices according to the invention.
- the combination of these two possibilities would even make it possible to achieve four progressively decreasing thicknesses.
- the invention is compatible with any arrangement varying the thickness, in particular the degree of positive or negative stretching, of the web deposited on the outlet conveyor. This makes it possible to combine the more or less abrupt variations in thickness due to the invention with more gradual variations between different points of the width of the same thickness zone defined by the invention.
