Definitions
- the object of the present invention relates to a multi-device machine of false twist, specially designed for the in-line preparation of the threads (by means of false twist), just before entering the needle / s of all kinds of looms, knitting machines , etc. of technical threads and textile threads.
- Said machine is specially designed to house multiple devices of false twist, where each device causes the thread or threads that pass through said device to be temporarily twisted by the effect of the false twist a certain number of turns / meter on its way to the needle of what can be a loom, a knitting machine, etc.
- the warp threads that feed the needle knitting machines and the looms present a series of limitations when passing each of the threads or group of threads gathered through the hole of their respective needle. Said thread or group of threads together may or may not be twisted depending on the effect that is desired to be given to the final fabric, and when passing through the respective needle there is a high probability that there will be a breakage of the thread / s and / or the corresponding needle when the thread (s) are encased with the needle because of the existence of said thread (s), a knot caused by the difference of unit tensions in the case of groups of threads together, or also because of the existence of some irregularity in the thread / s itself such as baguillas, ties, etc.
- This phenomenon causes that the efficiency of production of said machines is very low due to the loom stoppages made by the operator and caused by said phenomenon, being usual to apply previous corrective measures to eliminate as much as possible such problems, centered on the verification that The raw material that feeds these machines is manufactured with a previous torsion operation and in good regular conditions, without knots, no bagas, etc.
- the multi-device false torsion machine restructures the current process of production of the carpet or fabrics, since the operation of creating false torsion is added "in line" to the general process of tissue production, intercalating before the needles of the machine of needles either this loom or knitting needles, which does not extend the period of production of carpets or fabrics even if it is an added operation.
- the previous twisting process can be eliminated by installing the multi-device in-line false twist before of entering the thread into the needles or the knitting machine.
- the multi-device false twist machine is composed of a fixed frame that can have adjustable elements in which the false twist devices (already known in the market) are mounted, in variable number depending on the number of needles you have the loom or knitting machine.
- 1500 devices in needle looms Said machine shall be arranged in such a way that the devices can be located at a distance and with the appropriate orientation with respect to the needles of the loom or knitting machine, in order that the threads from the reels of the feeder fillet pass, prior to their arrival at the needle / s, through the devices and the effect of false twisting produced by the devices reaches the needles of the loom or knitting machine.
- each false torsion device is provided with a drive system, either pneumatic by means of solenoid valves, electro-mechanical by electric motor and mechanical transmission or others, depending on the type of device applied to those known in the market.
- said devices generate a false twist on each of the threads / s that pass through said respective false twist device.
- a false twist device is an apparatus that essentially has a point where the thread enters the device and a point where the thread from said device is produced, as well as an intermediate zone between said two points in which a rotation of thread is generated with respect to its own longitudinal axis in one or another direction of rotation as it is operated.
- the multi-device machine of the invention supports the installation of false twist devices of any type known in the art, and, therein, the amount of turns per unit of time generated on the thread, the direction of rotation of said thread and The duration of the generated rotation movement are the parameters whose values are set before starting the warp manufacturing operation.
- the combination of the values of said parameters will be controlled and directed by a central unit through a work program and said combination of values will be specific depending on the caliber and type of thread or threads to be processed.
- the distance from the determined point, within the zone in which the rotation of the thread is generated, that is to say where the false twist is generated prior to the entry of the thread in the loom needle, to the respective loom or knitting needle also It can be adjusted and the direction of the thread oriented according to each different product to be processed, so that the thread (s) have, just before it enters the needle, so that the thread / s have , just before entering the needle, the number of twists necessary for the elimination of bagas or loops and for the passage through said needle (s) to occur without incident. Even if Generally, once said distance and orientation have been set, it can or can be touched because in the vast majority of threads it is already correct.
- Figure 1 View of the multi-device of false twist mounted on a "TUFTING" needle loom
- Figure 2 Front view of the false twist multi-device 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 more and already twisted or not, from a loom feeder, at an intermediate point between said fillet and the needle (8) of the loom or knitting so that at the moment in which said thread (s) come into contact with said needle (8) it has a certain number of twists per meter, thus achieving the ability to provide the thread with greater regularity and roundness, thus avoiding problems of rupture due to the formation of bagas, loops or other causes derived from insufficient torsion.
- the wires (1) coming from the feeder fillet are led to the frame (3) in which the false twist devices (4) are mounted used, among the various types known in the art, driven by its drive system.
- the devices are mechanical rollers all driven simultaneously by a belt (6) from an electric, mechanical, pneumatic motor, etc.) of the known can be used to carry out the invention. It may or may not be necessary to use one or more rollers (2) to change the direction of the thread depending on the distance and orientation chosen for each product.
- the wires enter and pass through the respective devices, which produce the twists of the hllo / s, said twists developing in a certain direction in the thread portion between the device (4) and the roller (2) (or between the device 4 and the feeder fillet when rollers are not used) and in the opposite direction in the thread portion between the device (4) and the needle (8).
- the number of twists per unit of length that the thread carries when entering the needle (8) depends on: the relative position of the device (4) with respect to the roller (2) and needle (8) positions, the number and size of the threads to pass through the same needle and if said threads are twisted together, the degree of false twist generated by the device (4), the feeding 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 determined, of each cycle, all of which is determined and programmed according to the characteristics and needs of the thread to be processed.
- the drive motor (5) is provided with a conventional thread control system with respect to the degree and direction of the false twist.
- a general program determines the variables of the speed and rotation of the thread, including the sequence of movement and the specific duty cycle for the type of thread to be processed.
- the essential characteristic of the multi-device false torsion machine is that it is mounted in line inside the main machine, that the operation of the devices is developed as one more of the series of operations of said main machine, and that the operation of the devices do not condition the processing speed in any way of the thread in the needle loom, knitting needles, etc., although it does increase the operating efficiency of said loom, knitting machine, etc.
