Definitions

  • the object of the present invention is related lo a multi-device false-twist machine, especially designed for on-line preparation of thread (by false-twisting), just before entering the needle/s of all types of loops, knitting machines, etc. of technical and textile threads.
  • Said machine is especially designed in order lo house several false-twister devices, where each device makes the thread or threads that pass through said device twist provisionally because of the effect of the false-twisting of a set number of rotations/meter on its path lo the needle of what may be a loom, a knitting machine, etc.
  • the warp threads that feed needle knitting machines and looms present a number of limitations when sending through each thread or group of threads joined by the hole of its respective needle.
  • Said thread or joined group of threads may be twisted or not depending on the effect desired in the final fabric, and upon passing through the respective needle there is a high probability that the thread/s and/or corresponding needle should break due to the friction among the thread/s and needle due to the existence in said thread/s of a knot caused by the difference in unitary tensions in the case of groups of joined threads, or also due lo the existence of certain irregularities in the thread/s itself/themselves such as loosenings, loops, etc.
  • This phenomenon makes the production efficiency of said machines very low due to the operator's stopping the loom and provoked by said phenomenon, the application of previous corrective measures being habitual in order to present said problems as far as possible, centred in checking that the prime materials that are fed into said machines are produced with previous twisting operations and in good conditions of regularity, without knots, loosenings, etc.
  • the multi-device false-twisting machine re-structures the present carpet or fabric production process, since the operation of creating false-twisting is added “on-line” to the general fabric production process, inserted before the needles of the needle machine, whether the latter is a loom or a needle knitting machine, which does not lengthen the carpet or fabric production process in spite of being an additional operation.
  • pre-twisting of the thread is only carried out as a preventive measure in order to increase the regularity of the thread/s, and as a consequence the efficiency in the needle loom, needle knitting machine or needle braiding machine, in an improved acceptance of the thread/s passing through its respective holes, the process of pre-twisting can be eliminated by installing the multi-device false-twisting machine on-line before the thread enters the needles or the needle knitting machine.
  • the multi-device false-twisting machine is composed of a fixed frame that may include adjustable parts, on which the false-twisting devices are mounted (as is already known in the market), in a varying number depending on the number of threads that the loom or knitting machine has On knitting machines with one hole, the machine has one device, and up to 1.500 devices on needle looms. Said machine is disposed so that the devices may be located at a distance and with the appropriate orientation in relation to the needles of the loom or knitting machine, with the objective that the threads proceeding from the spools of the input creel, before arriving at the needles, should pass through the devices and the false-twisting effect produced by the devices should reach the needles of the loom or knitting machine.
  • each false-twisting device is provided with an activation system, whether pneumatic by electrovalves, electromechanical, with an electric motor and mechanical transmission, or others, depending on the type of device applied among those known in the market.
  • said devices generate a false-twist on each of the thread/s that pass through said respective false-twisting device.
  • a false-twisting device is an apparatus that, essentially, has a point at which the thread is sent into the device and a point at which the thread comes out of said device, as well as an intermediate zone between the two aforementioned points at which the thread is rotated with respect to its own lengthwise axis in one or another rotation direction depending how it is activated.
  • the multi-device machine of the invention allows the installation of false-twisting devices of any of the types known in the state of the art, and in it, the number of rotations per unit of time generated on the thread, the direction of rotation of said thread and the duration of rotation movement generated are the parameters whose values are set before starting the warp production operation.
  • the combination of the values of said parameters is controlled and directed by a central unit by a working program and said combination of values is specific depending on the calibre and type of thread or threads to be processed.
  • the distance from the set point, within the zone in which the thread is rotated, that is, where the false-twist is generated before the thread enters the loom, up to the respective needle of the loom or knitting machine can also be adjusted and the direction of the thread oriented depending on each different product to 5 be processed, with the purpose of the threads having, just before entering the needle, the necessary number of twists to present loosenings or loops and so that they may pass through said needles without any trouble.
  • said distance and orientation it may be maintained as in the majority of threads it is already correct.
  • FIG. 1 View of the multi-device false-twisting machine mounted on a “TUFTING” needle loom
  • FIG. 2 Front view of the multi-device false-twisting machine mounted on a “TUFTING” needle loom.
  • the essential object of the invention being to generate twists in the thread or threads, whether one or several and already twisted or not, proceeding from an input creel of the loom, at an intermediate point between said creel and the needle ( 8 ) of the loom or knitting machine so that as soon as said thread/s make contact with said needle ( 8 ) it is provided with a set number of twists per meter, thus by such an effect providing the thread with greater regularity and roundness, therefore preventing breakage problems due to the formation of loosenings, loops or other causes derived from insufficient twisting.
  • the thread ( 1 ) proceeding from the input creel are sent to the frame ( 3 ) on which the false-twisting devices ( 4 ) being used are mounted, from among the different types known in the art, activated by their activation system.
  • the devices are mechanical rollers that are activated simultaneously by a belt ( 6 ) proceeding from an electrical, mechanical, pneumatic, etc. motor, among those known can be used to put the invention in practice.
  • it may or may not be necessary to use one or more thread direction change rollers ( 2 ) depending on the distance and orientation chosen for each product.
  • the threads enter and cross through the respective devices, which produces the twists in the thread/s, said twists being made in a set direction and on the portion of thread between the device ( 4 ) and the roller ( 2 ) (or between the device ( 4 ) and the input creel when rollers are not being used) and in the opposite direction on the portion of thread between the device ( 4 ) and the needle ( 8 ).
  • the number of twists per unit of length that the thread carries at the time it enters into the needle ( 8 ) depends on: the relative position of the devices ( 4 ) with respect to the roller ( 2 ) positions and the needle ( 8 ), the quantity and calibre of the threads to be sent through a single needle and whether said threads are twisted amongst themselves, the degree of false-twist generated by the device ( 4 ), the input speed of the warp thread generated by the loom, the cycle of rotation movements generated by the device ( 4 ) and the sequence of rotation movements and stops, if set, of each cycle, all of which is determined and programmed depending on the characteristics and needs of the thread to be processed.
  • the activation motor ( 5 ) is provided with a conventional thread control system with regards lo the degree and direction of the false-twist.
  • a general program sets the variables of speed and thread rotation, including the specific movement sequence and the work cycle for each specific type of thread to be processed.
  • the essential characteristic of the multi-device false twisting machine is that it is mounted on-line within the main machine, that the operation of the devices is carried out as just one of the series of operations of said main machine, and that the operation of the devices does not in any way condition the thread processing speed in the needle loom, the needle knitting machine, etc., although it does increase the efficiency of the functioning of said weaver, knitting machine, etc.
