Definitions

  • the invention relates to a system for forming a pleated textile product.
  • Pleated textile products are used for instance as basic material for making clothing, usually women's clothing, and for the production of furnishing textiles, particularly window-covering products such as curtains, so-called 'panel tracks' and the like, and wall covering products.
  • a strip of textile material is fed to a pleating station in which one or more folds are arranged in the material.
  • the known pleating stations comprise, depending on the direction of the folds which must be arranged in the material, one or more upward and downward movable pleating knives received in a guillotine-like guide frame.
  • pleats are arranged in transverse direction in the material, wherein the length of the pleats is thus limited by the maximum possible length of the knife on the one hand and the maximum width of the textile length on the other.
  • the formed pleats are otherwise immediately fixed in this method as a result of the temperature of the pleating knives.
  • US 2,786,616, upon which the precharacterising portion of appended claim 1 is based, and FR 330,446 describe pleating systems having means for feeding material, means for pleating the material in a longitudinal direction and means for fixing the pleats.
  • US 2,786,616 has a pair of coacting rotatable rollers as part of the means for fixing.
  • the invention now has for its object to provide a system for manufacturing pleated textile products with which a textile material can be pleated and optionally finished on industrial scale and at great speed, and with which products of very diverse dimensions can be manufactured.
  • a system is provided according to the invention with:
  • the pleating device can herein comprise at least one mould with a profiled opening corresponding with the desired contour of the pleated products.
  • a continuous length of material can hereby be pleated with little effort.
  • the roller can have a relatively large diameter. Deformation in transverse direction of the just pleated material is hereby minimized.
  • the system is preferably also provided with a device for finishing the length of material with the fixed pleat or pleats.
  • This finishing device can comprise cutting means for cutting the length of material into pieces in transverse direction, in addition to cutting means for severing one or more longitudinal edges of the length of material.
  • the cutting means which are preferably adapted to heat-seal the formed cut edge so as to preserve the form of the product, can preferably comprise ultrasonic cutters.
  • the cutting means can be further adjustable in order to-form textile products with different dimensions.
  • further means controllably connected to the cutting means can be present for detecting the position of the length of material, which may for instance comprise optical sensors.
  • a buffer can also be provided for temporarily storing the material for cutting, for instance during adjustment of the cutting means.
  • the system can further comprise a device for mutually connecting a number of pieces in longitudinal direction.
  • This connecting device can for instance comprise a sewing machine, in particular a longitudinal seam sewing machine.
  • a further device can be arranged between the finishing device and the connecting device for turning over one of the severed pieces, which can then be stitched to the other pieces in the reversed position.
  • the invention also relates to a pleating device, a fixing device, a finishing device and a connecting device for use in a system as described above.
  • a system 1 for forming a pleated textile product comprises a device 2 for feeding a length of flat material 3, a device 4 for arranging one or more longitudinal pleats 5 in the length of material 3 and a device 6 for fixing the pleat or pleats 5.
  • the system 1 is further provided with a finishing device 7, which is placed in series with fixing device 6 and which is adapted to cut longitudinal edges 8 from the length of pleated material 3.
  • Behind finishing device 7 can be arranged a conveyor table or belt 9, behind which a winding unit 10 is arranged (fig. 1). This arrangement is used particularly when, after pleating, the material will be further processed into a textile product at a different location.
  • finishing device 7 can also be adapted to cut the length of pleated material in transverse direction, whereby pieces or panels 48 are formed.
  • a conveyor belt or table 9 can then also be present to feed pieces or panels 48 through to a take-off device 11 on which pieces 48 are received to then be mutually connected to form a complete product (fig. 2).
  • Feeding device 2 comprises a holder 12 for a supply roll 13 and a number of tension rollers 14, 15 and 16 (fig. 3). At least the last tension roller 16 is herein provided with a profile 17 running outward on both sides from the centre, whereby length 3 is pulled tight in transverse direction. Feeding device 2 further comprises two co-acting contour rollers 18, 19 whereby the length of material is already brought to some extent into the desired pleat form.
  • Pleating device 4 comprises a mould 20 with an opening, the contour of which corresponds with the ultimately desired pleat pattern in the material.
  • the contour which is formed by co-acting standing and hanging T-shaped guides 21 and 22, herein tapers gradually in the feed direction.
  • T-shaped guides 21, 22 are relatively high and narrow on the infeed side (fig. 4A), while on the out-feed side they are relatively low and wide whereby the material is gradually carried into the desired (box) pleat form (fig. 4B).
  • Forms of mould other than shown here are otherwise also possible.
  • a sawtooth mould could thus possibly be used if so-called flat pleats have to be arranged in the material instead of the shown box pleats.
  • Fixing device 6 follows on immediately from pleating device 4, which can be virtually integrated therein (fig. 5).
  • Fixing device 6 is provided with a roller 23 of relatively large diameter and a pressure belt 25 co-acting therewith which is guided over a number of rollers 24.
  • Roller 23 is heated, whereby pleats 5 are fixed in the length of material 3 by a combination of heat and pressure.
  • an insulation cover 55 is placed around the part of roller 23 which does not co-act with pressure belt 25.
  • the material in fact consists of a plurality of layers after pleating, deformations thereof transversely of the plane must be avoided as far as possible, since any deflection will result in the outer layer having to cover a greater distance than the inner layer, whereby creases could eventually be formed in the inner layer.
  • the choice of radius for roller 23 is therefore as large as possible, whereby the curving of the length of material 3 remains limited during fixing.
  • the infeed of the roller moreover lies substantially in one line with the outfeed of mould 20 of pleating device 4, so that the length of material 3 is in principle only bent in one direction.
  • finishing device 6 Since in the shown embodiment of finishing device 6 use is made of a per se conventional roller, this latter is here placed at an angle ⁇ in a frame 26, whereby the infeed is indeed situated at the same height as pleating device 4. After being released from roller 23 the length of material 3 is guided along a cooling device 27, whereafter the material is deflected downward over a number of rollers 28 in the direction of finishing device 7.
  • Finishing device 7 comprises means 29 for cutting the or each longitudinal edge 8 off the length of material 3, in addition to means 30 for cutting length of material 3 in transverse direction into pieces or panels 48.
  • Both longitudinal cutting means 29 and transverse cutting means 30 can be formed by ultrasonic cutting units with a lower knife or horn 31 and an upper knife or cutting wheel 32.
  • the choice of an ultrasonic cutting unit results in the material being heat-sealed immediately on forming of the cut, whereby the form, particularly the pleat form, is preserved and, in addition, fraying of the material is prevented.
  • With the embodiment having upper knives and lower knifes moving away from and towards each other the cutting means 29, 30 can moreover be displaced without damaging the material, whereby possible cutting losses are minimized.
  • the longitudinal cutting means 29 are adjustable in transverse direction along a beam 53, wherein the one knife 29 has only a fine adjustment with a displacement range of about 175 mm, this being particularly intended to enable following of variations in the progression of material 3, while the other knife has a relatively large adjustment range in the order of 1.40 m, whereby material lengths of different width can be formed.
  • This knife also has a fine adjustment in order to follow the progression of pleats 5 in length of material 3.
  • Longitudinal cutting means 29 are controlled in each case by an optical sensor 33, here a photocell, which detects the progression of pleats 5.
  • the position of optical sensors 33 is also adjustable. Adjustment of the knifes and sensors can herein take place both manually and pneumatically.
  • the finishing device 7 is provided with a first buffer 34.
  • This buffer comprises a compensation roller 35 displaceable transversely of the transport direction of the material and a guide plate 36.
  • compensation roller 35 drops slowly downward in the direction of the position 35' shown in dotted lines, while feeding device 2 and fixing device 6 run on slowly.
  • the speed at which roller 35 drops is of course adapted herein to the speed at which the material leaves fixing device 6.
  • Drive'rollers 37 and 38 are otherwise rollers which are only rotatable in one direction and which co-act with a pressure roller 39 respectively 40 arranged thereabove. Strips 41 severed by longitudinal cutting means 29 along the edges 8 of length of material 3 are eventually discharged downward via a guide roller 42.
  • finishing device 7 is also adapted to perform a transverse cutting operation.
  • a transverse cutting unit 30 is present which takes a dual form in the shown embodiment in order to increase the effectiveness and reduce the time length of material 3 has to be stopped.
  • Transverse cutting unit 30 is herein displaceable in transverse direction of length of material 3 along a beam 54, wherein, as stated, the length of material 3 is brought to a standstill.
  • finishing device 7 has a second buffer 43 which is likewise formed by a compensation roller 44 and a guide plate 45 placed thereunder.
  • a driven roller 46 which co-acts with a roller 47 to tighten the length of material 3 is temporarily stopped.
  • Compensation roller 44 then moves downward at a speed such that all the material supplied by longitudinal cutting means 29 is stored in buffer 43. After the transverse cutting operation has been performed and the driven roller 46 has been started again, the material is pulled out of buffer 43 by temporarily causing this roller to rotate more rapidly.
  • the material of the length 3 can otherwise be supported during both the cutting operation in longitudinal direction and the transverse cutting operation.
  • a static support for instance by means of a pneumatic system with which the material is sucked against a surface.
  • a dynamic support system for instance in the form of guide plates or guide rollers, whereby the material is stabilized and the pleats can optionally be opened up in order to enable a cutting operation to be carried out in the pleat without damaging the surrounding material.
  • transverse unit 30 may take a "flying" form and to thus co-displace with the length of material 3 for cutting (fig. 2).
  • finishing device 7 the material reaches a conveyor belt or table 9, whereby it is discharged.
  • this conveyor belt or table 9 will be provided with means for controlling transverse cutting means 30.
  • control means then comprise a sensor (not shown here) which ascertains that a determined quantity of material has passed through transverse cutting means 30, whereafter these latter can be activated.
  • the pieces or panels 48 formed by transverse cutting means 30 can finally be taken off conveyor 9 and stacked by a transfer device 11.
  • Panels 48 can also be passed directly to a connecting device in which they are mutually connected in longitudinal direction. This will apply particularly to pieces and panels 48 which are used in the form of curtains, the width of which generally amounts to a multiple of the width of a piece of fabric.
  • the pieces or panels are used as panel tracks, it will generally not be necessary to mutually connect them, but it will only be necessary to arrange all manner of suspension members, weightings and the like therein.
  • a slightly different cutting pattern is also chosen for this purpose.
  • the length of material is cut on either side on a fold line 5 (fig. 7A), whereafter one of the panels is turned over prior to the connecting.
  • the short leg 51 of the last pleat of this panel 48' is unfolded slightly and connected to the long leg 52 of the last pleat of the other panel 48 (fig. 8), whereby after this second panel 48' has been folded back to its original position a relatively wide pleated panel results, the seam 50 of which is invisible from the visual side 49 of the panel.
  • a cutting line is herein chosen in a pleat lying on the rear side, which falls behind the pleat on the visual side 49 during use (fig. 7B).
  • the method and the system according to the invention enable pleating, cutting to size and processing into end products of lengths of textile material at relatively great speed and on industrial scale.
