Definitions

  • Such knotting device which is generally mounted upon an arm adapted to swing in a vertical plane and is moved towards the yarns to be knotted, produces knots which are not always of the same thickness, or of which the yarn ends are not always of the same length. This may be due to dust which has settled upon the yarn, to yarn particles which remain in the knotter device, or lacking of perfect Working of the knotter device whereby the yarn ends are not cut off at the correct length or not pulled with the required tension. It results therefrom that, when using such knotted yarns, a less valuable fabric is afterwards produced by Weaving.
  • the device consists essentially in the combination of a control means adapted to check the thickness of the knot by electronic means, with a cutting tool actuated by said control means, said tool sectioning the knotted yarn when the predetermined thickness of the produced knot is transgressed, guiding means adapted to guide the knotted yarn accurately within said electronic control means and under the cutter tool, means for keeping the knotted yarn during a determined time within the electronic control means and under the cutter tool and a cleaning means adapted to keep the control means in dust-free condition.
  • the knotted yarn is always securely introduced within the control means and brought under the cutter tool and said yarn is also perfectly steadied for passing the control operation. Furthermore, in the case of a tool thick knot, the yarn is immediately sectioned after the control operation by said cutter tool, again knotted by the knotter device and the yarn portion with the bad knot is cut down in this way. It results therefrom that it is possible to obtain in this way faultless yarns and fabrics.
  • the cleaning means care for avoiding dust to penetrate within the control means, the dust being capable of interfering with the controlling of the yarn.
  • FIGURE 1 is a perspective view illustrating a part of a cross-winding machine upon which has been applied the device according to the invention
  • FIGURE 2 is an enlarged perspective view illustrating said device
  • FIGURE 3 illustrates a top plan view
  • FIGURE 4 is a front view thereof
  • FIGURE 5 illustrates a side elevation according to the arrow P of FIGURE 3, and in which the device is brought in such position in which the yarn is guided into the control means;
  • FIGURES 6 and 7 are similar views as that illustrated in FIGURE 5, but wherein the device is respectively in the control position and in the position of withdrawal.
  • the knotter device 1 is fixed upon a swinging arm 2.
  • a supporting plate 3 upon which is mounted an electronic control device 5 known per se by means of an angle section 4.
  • Said device comprises the electronic apparatus, in which for instance is provided an electric cell arranged in the passage 6 of the aforesaid control device.
  • a cutter tool 7 Within the said passage 6 of the control device 5 is provided a cutter tool 7.
  • FIGURE 3 is indicated in dotted lines the control zone by reference 8 and the cutter zone by reference 9.
  • Upon the passage 6 is connected the endof a tube 10 of which the other end is connected to a compressed air device (not shown).
  • This tube 10 is provided with a valve (not shown) which gives automatically passage to air at determined time periods.
  • Each guide plate has a V-shaped indentation, respectively 13-14 ending in a groove, respectively 15-16.
  • the guide plates are arranged in such a manner that the said grooves 15-16 reach until behind the front face of the control device 5.
  • a latch 17 provided with a notch 18 with rounded edges 19. Said latch is fixed in such position that the rear part of the grooves 15-16 will limit a space with the front vertical part of the identation 18, space in which the knotted yarn is introduced and maintained for the control operation.
  • the yarns A-B to be connected are at rest as shown in FIG- URE l.
  • the swinging arm 2 moves frontwise and the upper yarn A is guided along the upper slope of the V-shaped indentations 13-14 of the guide plates 11-12 towards the grooves thereof 15-16, whereas the lower yarn B is repelled by the bottom part of the aforesaid plates 11-12 (FIGURE 5).
  • the upper yarn A after a further swinging of the arm 2, is guided in the rear part of the grooves 15-16 of the plates 11-12, the yarn A engages the notch 18 of the latch 17 and such yarn is held steadied in this position within the control and cutter zones, respectively 8-9, of the control device 5 (FIGURE 6).
  • the knot C is formed in the known manner within the knotter device 1.
  • the winding of the yarn is resumed, whereby the formed knot will pass along the control zone. If the produced knot is good, the yarn will progress further as usual; if however it is not in good condition or character, the cutter tool 7 is operated by the electronic control device 5 in such a manner that the yarn is cut up and that the winding of the yarn is stopped.
  • the yarn ends to be knotted again are gripped in the known manner and a next knot is made by the knotter device 1 as described herebefore, after which the wrongly knotted yarn ends A-B are cut out by the cutter means of the knotter device. After this the Winding is resumed and a new control is performed.
  • the arm 2 is retracted, whereby the upper yarn portion A slides along the rounding 19 of the notch 18 outwards (FIGURE 7), while the winding of the yarn is continued.
  • the valve of the tube 10 is opened so that the from dust and yarn particles.
  • a device for controlling the knots made by the knotter of cross-winding machines comprising in combination electronic means controlling the character of the knot, a cutter tool operated by said electronic means for cutting down the knotted yarn when the predetermined character of the formed knot is transgressed, guiding means guiding the knotted yarn accurately within the aforesaid electronic control means and under the cutter tool, means for holding the knotted yarn during a predetermined time within the electronic control means and under the cutter tool and a cleaning means for making the control means dust-free.
  • a device for controlling the knots made by the knotter of cross-winding machines as per claim 1, comprising a knotter mounted upon an arm swinging in a vertical plane, the electronic control means, the cutter tool, the guiding means, the means for holding the knotted yarn during a predetermined time and the cleaning means mounted upon said swinging arm close to the knotter.
  • a device for controlling the knots made by the knotter of cross-Winding machines as per claim 1, comprising guiding means formed with two plates having each a V-shaped indentation located in front of the electronic means controlling the thickness of the knot, a groove in said plates in prolongation of said indentation at the apex therefrom, said groove extending behind the front face of the electronic control means.
  • a device for controlling the knots made by the knotter of cross-winding machines as per claim 1, comprising in com-bination an electronic control device, guide plates having V-shaped indentations and grooves forming part with said indentations and a latch with a notch to be engaged by the yarn, the arrangement being such that the knotted yarn is guided along the grooves of the guide plates into the inner part of the electronic control means, the rear part of the grooves and the front vertical part of the notch leaving a space in which the knotted yarn is introduced in front of the control means.
