Definitions

  • the woof thread feed of a weaving machine consists primarily of a number of components, such as thread bobbins, thread extraction machinery and/or unwinding devices and other storage devices, whereby the woof thread follows a determined path from the yarn bobbin until it is offered up to a woof mechanism, by which the yarn is finally fed to the gap.
  • the bobbins used for this purpose are mostly each provided with a reserve bobbin, whereby the end of the thread wound around them is connected to the end of the thread on the active bobbin, such that when the active bobbin is empty, the mechanism automatically switches to the reserve bobbin.
  • Feed systems are also known (US 4215 728) whereby a number of unwinding bobbins are used which work in turns to achieve a desired effect.
  • This system is used in a woof system in which use is made of several yarns of different types or colours.
  • the system is provided with an electronic thread travel monitoring device between supply bobbin and storing device. In the event of a break of a wift thread, the monitoring device causes the machine to step before the broken thread meters the weaving died.
  • the interchanging of the woof yarns to be fed to the gap can be achieved by offering up the or supplying the different yarns alternately to a woof feed device, which can consist of, for example, claw, blower or similar.
  • a disadvantage of all these known woof yarn feed methods lies in the fact that a break in the thread always requires a stoppage whenever such a break occurs outside the gap, irrespective of whether the break occurs between a bobbin and the woof mechanism or the woof feed device, between a bobbin and an unwinding device, on the upper surface of an unwinding device, between the unwinding device and the woof mechanism or between the two coupled bobbins.
  • the claim presents a feed for the woof thread of a weaving machine whereby a break in the thread before the gap does not result in a stoppage. According to the invention, this is achieved by the features of claim 1 having, in the advantage that the weaving machine can continue to operate without interruption.
  • the woof thread feed system consists primarily of the combination of two components 1 and 2, each of which is formed of a yarn bobbin; a woof mechanism 3; at least one detector 4, located along the yarn path of one of the woof thread 5 or 6, which are formed by the unwinding of bobbins 1 and 2; and a drive unit 7, to which detector 4 is connected, and from which a drive line 8 runs to woof mechanism 3.
  • the gap 9 of the weaving machine is schematically represented by means of a dotted line.
  • a single blower in which a mechanism or device ensures that the desired woof thread, either 5 or 6, is automatically fed to the entry of the blower.
  • woof mechanism 3 consists principally of a thread presenter of a type already known, which, according to this embodiment, offers up one of the two woof threads, 5 or 6, to the claw, depending on the signal transmitted by drive unit 7.
  • gap 9 is provided with the required woof threads by alternately offering up woof threads 5 and 6 to gap 9 through alternating action of woof mechanism 3. If one of the detectors 4 and 10 detects, on the one hand, a broken thread, or, on the other hand, the running out of one of the yarn bobbins, drive unit 7 makes sure that the full weaving cycle is performed from one only of components 1 and 2, such that the section where the fault or the end of a bobbin is detected is cut out.
  • the feed mechanism for the woof thread consists primarily of two components, 11 and 12, which replace one another, a woof mechanism 3, a drive unit 7, at least one of the aforementioned detectors 4 or 10, located along the path of the woof threads 5 or 6.
  • each of components 11 and 12 consists of two bobbins, respectively 13 - 14 and 15 - 16.
  • the ends 17 - 18 of each of the first bobbins, respectively 14 and 15, of components 11 and 12 are connected to the ends 19 - 20 of the thread on the related second bobbins, respectively 13 and 16.
  • Detectors 21 and 22 offer the advantage of faster detection of the end of a bobbin than, with detectors 4 and 10, with the result that in this event, action is even faster, in other words, it is possible to switch woof mechanism 3 even more quickly.
  • the operation is as follows.
  • an embodiment of the invention is represented schematically, in which, in addition to the aforementioned components 11 and 12, which, as stated, consist of two-bobbin sets, components 25 and 26 are also present.
  • These components 25 and 26 here consist of unwinding devices which are installed in the yarn paths of, on the one hand, woof thread 5 and, on the other hand, woof thread 6.
  • These components can also take another form, and are not necessarily limited to unwinding devices. These other forms are most frequently a runout device or a thread extraction device, which may or may not be combined with a thread storage appliance.
  • detectors 4 and 10 are located along woof threads 5 and 6 in the section located between bobbins 14 - 15 and components or unwinding devices 25 - 26, in order to be able to ascertain a broken thread between unwinding devices 25 - 26 and woof mechanism 3, detectors, 27 and 28, are provided here as well.
  • supplementary detectors 29 and 30 are provided on unwinding devices 25 and 26, which emit a signal as soon as the number of turns falls below a fixed minimum.
  • drive unit 7 also provides for cutting in and out of components or unwinding devices 25 and 26, by means of drive lines 31 and 32, along which their operation is controlled.
  • the system can operate with more than two feed systems per type of thread. In the case of three systems, for example, the systems can operate at a third of the capacity they would have if operating alone. If a thread break occurs, one of the feed systems drops out, and the others switch to half capacity. If a further thread breaks, one system operates at full capacity.
  • the feed system according to the invention can be embodied in multiple form if the system is to operate with more than one type or colour of woof yarn.
