Definitions

  • the present invention relates to a tufting method and a device for implementing this method.
  • the tufting technique applied particularly in the production of carpets intended for flooring, consists of stitching linearly through a weft fabric of needles carrying the thread, which is held by swivel hooks during each stitching, needles and hooks being located on either side of the weft fabric.
  • the unwinding to the fabric is done in a continuous and regular way.
  • the needles and the hooks are placed in series in modules which together constitute respectively the bench of needles and the bench of hooks.
  • the bench of needles can move along the longitudinal axis thereof relative to the (transverse) direction of advancement of the fabric, but the hook bench remains fixed.
  • the movement of the needle bank is limited, since each hook a hook must be in front of a needle.
  • the displacement of the needle bank is a function of the distance between two successive needles (designated in the tufting technique as a gauge) and must correspond to one or a multiple of the gauge.
  • Another possibility is to change the gauge pitch, but switching from one gauge to another requires changing and adjusting the banks of needles and the banks of hooks. And the modification of the gauge requires the adjustment of the control devices, cams, hydraulic equipment, etc ... These adjustments are long and tedious, so that the tufting looms are generally left at a standstill when the workshop does not have to not produce the gauge and the pile height for which they have been set.
  • the object of the present invention is to propose a tufting method and a device for implementing this method avoiding the drawbacks mentioned.
  • Another object of the invention is to propose a method and a device for the implementation of this method making it possible to produce a large possibility of variant designs.
  • Yet another object of the invention is to propose a tufting process allowing movements of the needles independent of the gauge.
  • a series of needles arranged one beside the other with a given spacing, each carrying a thread, prick through a weft fabric which unwinds normally, while that a series of hooks, located on the other side of the fabric, retain the thread, characterized in that several stitching operations are carried out according to successive and simultaneous movements in the lateral position of the needles and the hooks in both directions while the unwinding of the weft fabric is interrupted, the fabric being kept fixed and stretched during these lateral displacements.
  • the device which is the subject of the invention consists of a bench of needles, a bench of hooks, means for unwinding a weft fabric between the needle bank and the hook bank, means for stitching the needles carrying the thread through the fabric and means for pivoting the hooks to hold the thread passing through the fabric, characterized by means for controlling the advancement of the weft fabric by jerking at variable speed and for keeping this fabric fixed during successive lateral stitchings, as well as means for controlling the lateral movement of the bank of hooks synchronously with the displacement of the bench of needles.
  • FIG. 1 which schematically shows the stitching according to the state of the art, it shows a weft fabric (a) which unwinds around a roller (b) and is in a horizontal plane (arrow c) below a bench (d), the axis of which is perpendicular to the axis of the direction of unwinding of the fabric (a).
  • the bench (d) carries the needles (e) according to a fixed gauge (f).
  • the bench (d) can move in a back and forth movement (arrow g) allowing a zigzag design (h).
  • the wire (i) is supplied from a battery of coils (not shown).
  • the hooks, placed on a bench of hooks in a fixed way, are below the fabric and are not visible on the diagram.
  • FIG 2 shows a diagram of the same type as that of Figure 1 but according to the technique of the invention.
  • a weft fabric 1 unwinds along a vertical plane (arrow 13) between a bench 3 of needles 4 and a bench 10 of hooks 6 ( Figure 3).
  • the needles 4 carrying the thread 11 are placed by modules 8 on the bench 3, just as the hooks 6 are placed by modules 9 on the bench 10.
  • the fabric 1 moves in a variable manner, therefore the distance 15 between two neighboring nozzles in a distinct horizontal plane is also variable depending on the variation in the displacement of the fabric.
  • the hooks 6 move synchronously with the needles 4 and there is no longer any reason to have uniform gauges; the distance 14 between two neighboring taps in the same horizontal plane can therefore also be variable.
  • the arrows 5 and 7 respectively represent the stitching direction and the horizontal positioning direction of the needles 4.
  • FIG. 2 clearly shows that the design 2 obtained can be complex and present an almost unlimited variety.
  • FIG. 3 shows the particular positioning of the needles 4 and the hooks 6.
  • the needles 4 have a flattened part 21, called a blade, carrying the eye 22 through which the thread 11 passes.
  • the longitudinal axis of each needle is rotated so that the blade 21 forms with the vertical plane 23 (on the direction of advance 13 of the fabric) an angle 24 which is 30 ° in the example considered.
  • the part of the hooks 6 which retains the wire 11 forms with the vertical plane 23 an identical angle 24 of 30 °, represented in FIG. 3 by the plane 25.
  • This plane 25 also illustrates the plane of crossing of the needle with its hook.
  • the arrow 26 represents the movement of the hooks 6.
  • the spacing 12 between two neighboring hooks (and two neighboring needles) is not fixed and may have multiple gauges.
  • the element 27 constitutes the support structure of the fabric. Together with the tension roller 28 and the fabric press element 29 (FIG. 4), it forms the device for permanent tension of the weft fabric 1.
  • FIG. 4 shows an example of unwinding of the weft fabric 1.
  • the fabric proceeds through a delivery cylinder 31 controlled by a stepping motor 32 for controlling the advance of the fabric and equipped with a electromechanical fabric locking system 33.
  • This system 32-33 makes it possible to stop the weft fabric during the stitchings and to control its advance according to variable steps.
  • the fabric 1 is stretched in the stitching area using the tensioning cylinder 28 controlled by a permanent tensioning motor 34 equipped with an electromagnetic coupler 35 voltage regulator. In the stitching area, the fabric passes through the support structure 27 and the fabric press element 29.
  • a conventional digital electronic control device for the machine is intended for general control of the trade. It must allow the longitudinal positioning of the benches and the control of the unwinding of the weft at a speed such that the stitching can be carried out at, for example, 600-700 strokes / minute. It also takes care of the automatic adjustments of the different tufting parameters: needle stroke, loop height, thread delivery, thread tension, weft fabric tension.
  • This conventional electronic device is known to those skilled in the art and the application of it does not come within the scope of the invention.
  • FIG. 4 An example of longitudinal guidance of the needle bank and the hook bank is shown in FIG. 4 by the references 38 and 39 respectively, it will be described in more detail below.
  • FIGS. 5 and 6 which describe an example of positioning of the banks of needles and hooks and of displacement of these, there is a motor 51 for stepping control, turning an endless screw 52 which carries a nut 53, which is connected by means of a ball joint 54 to the connection head 55 in communication with the bank 3 of needles 4 by means of a guide fitting 56 and in communication with the bank 10 of hooks 6 by means of a guide fitting 57.
  • the guiding of the movement of the hands 4 is schematically presented by the broken line 58, while the reference 59 shows the plane of the weft fabric 1.
  • FIG. 6 schematically shows the movement 69 of the hooks 6.
  • This movement is controlled by a twin cam 61 which rotates (arrow 62) and causes tilting (arrow 63) using the rollers 64, which press on its smooth profile, a head rocker 65.
  • This movement 70 is transmitted by the rod 66 to intermediate rockers 67 (two of which are shown), the movement 71 of which determines the guidance 68 of the movement 69 of the hooks 6.
  • the longitudinal guidance of the bench 10 of hooks is shown by the reference 39, the longitudinal guide of the bench 3 of needles is shown in FIG. 4 by the reference 38.
  • the device allows the positioning of the benches 3 and 10 with an accuracy of less than 0.1 mm.
  • the hooks are moved synchronously with the needles so that each needle forms a pair with its hook.
  • Moving a needle and its hook synchronously allows variable movements of value independent of the gauge. More, each pair (needle-hook) can be definitively adjusted and adjusted before the device is put into operation.
  • the weft fabric is unwound at a variable speed allowing a variation of designs.
  • the unwinding of the weft fabric is stopped during the stitching action.
  • the unwinding of the fabric is also stopped during certain movements of the pairs (needle-hooks) so that nozzles in the same longitudinal plane (relative to the transverse direction of advancement of the fabric) can be produced by the same pair.
  • each needle is always opposite the same hook whatever their position allows long longitudinal displacements without constraint of the needles which, combined with the stop or advance control of the weft fabric, leads to a possibility of wider color or design transfer. This technique makes it possible to "break" the repetitive alignment effect of the belt loops in the warp direction.
  • This advantage allows the adaptation of the number of needles and hooks; many more drawings with fewer pairs (needle-hooks) become possible.
  • the distance between the needles will be chosen according to the size of the design, the desired production and the rotation of the different qualities to be tufted.
  • needles are used having a flattened part, called a blade, comprising the eye of the needle, and the needles are mounted in the modules with the longitudinal axis (of each needle) turned so that the blade forms an angle with the vertical plane in the direction of advancement of the weft fabric.
  • This angle will preferably be between 15 ° and 45 °.
  • the hooks are also mounted in the modules so that the oscillation movement of each hook forms the same angle as that of the needle with which it forms a pair. This characteristic allows the thread to be cleared from the tip of the needle in order to avoid over-stitching of the latter.
  • the weft fabric is unwound during the stitching along a vertical plane and the bank of needles and the bank of hooks are placed in a horizontal plane on either side of the fabric.
