Definitions

  • the invention relates to a device for forming a leno edge according to the Preamble of claims 1 and 11 and a weaving machine with such Devices.
  • Devices for forming a leno edge are known from DE 25 38 135 C2 and from DE 28 11 275 A1.
  • the devices have two leno thread bobbins from which the leno threads are pulled off to form edges on the fabric.
  • specific features regarding their drive and control are not disclosed.
  • the devices are equipped with tensioning means, for example with tensioning springs.
  • EP 0 020 796 A1 is a leno thread delivery device for weaving machines known from which the leno threads under the action of a thread tensioner an edge forming device are supplied.
  • the type of drive the Edge forming device is when the device is a rotating disc or a Is equivalent means, not disclosed.
  • US Pat. No. 2,399,880 discloses a device for forming a leno edge on fabric to be produced on weaving machines.
  • the device consists of a rotary driven rotating disc, the drive of which is derived from the weaving machine drive. How the leno threads are kept taut when changing the leno pocket is not disclosed.
  • the leno thread bobbins are only equipped with a braking means which is intended to maintain the tension of the leno thread on the way from the leno bobbin to the leno disc.
  • a leno edge device of the type mentioned in the preamble of claims 1 and 11 is known from DE 195 48 955 C1.
  • the axis of rotation of the rotor is arranged parallel to the warp threads and outside the heald frames. Because of the free space for rotation next to the outer warp thread that is required by the guide element, a leno edge is generated that is at a distance from the actual fabric edge. Such a leno edge makes no sense in terms of application technology.
  • the axis of rotation of the rotor at an angle of preferably 45 ° arranged to the warp threads and in connection therewith a deflection roller for the Leno threads required.
  • the patent does not disclose whether this is a rotating or is a non-rotatably arranged or a rotationally driven deflection roller. In this respect, it is also not disclosed how a rotation of the Guide element of the leno selvedge jam twisted leno threads on the pulley is avoided, as in this Context is avoided that the leno thread formation is disturbed and how further leno thread breaks, which are based on the threading, be avoided.
  • the axis of rotation of the rotating body which is designed as a hollow shaft, is oriented at right angles to the warp threads.
  • at least two guide elements are arranged at a distance from one another on the hollow shaft.
  • a functional solution can consist here in that, for example, if the leno threads are in a change of subject, a tension force is applied to the leno threads.
  • the leno edge devices are preceded by a leno thread tensioning device, namely between the leno thread bobbins and the leno edge device itself.
  • a tensioning device which can be, for example, a pneumatic or mechanical mode of action, when the leno thread compartment is changed, tension is advantageously applied to the leno threads, which correctly guarantees the leno thread compartment formation following a change of subject.
  • such a pneumatically acting tensioning device consists of at least one cylindrically designed thread guide channel arranged between the leno thread bobbins and the leno selvedge device, in the plane of the leno thread run, in which both leno threads are guided and in which channel an injector nozzle opens opposite to the direction of withdrawal of the leno threads.
  • This tensioning device can be controlled in time with the leno thread change.
  • a pneumatic control is available for this purpose, with an electrically controllable control valve, which is connected to the programmable logic control of the weaving machine in a signal-transmitting manner.
  • the pneumatic medium is supplied, for example, from a machine-bound pressure accumulator via the control valve to the injector nozzle.
  • a mechanically acting leno thread tensioning device can consist, for example, of a means deflecting the leno threads from the delivery direction to the leno edge device, which means, controlled or uncontrolled, causes the thread deflection.
  • Another solution variant consists, for example, in a deflection lever which is operatively connected to a prestressed spring element.
  • the deflecting lever acts permanently on the leno threads or on their possible cords.
  • a leno thread tensioning device is placed between the yarn bobbins 7, 8 and the relevant leno selvedge device 1, which generates a tension in the leno threads that counteracts the withdrawal direction 28 of the leno threads 9, 10, in particular when changing the leno.
  • This ensures that the leno threads are tightened when changing subjects and that correct leno shedding is subsequently achieved.
  • incorrect weft entries, incorrect weft bindings and possibly leno and weft breaks are avoided. This leads to a reduction in machine shutdowns, a reduction in machine downtimes and consequently an increase in the productivity of the weaving machine.
  • the leno thread tensioning device 26 is a pneumatically acting device.
  • the device is preferably located in the plane of the leno edge formation in order to avoid further leno thread deflections on the way from the bobbins 7, 8 to the leno edge formation on the fabric 2.
  • the device 26 itself consists of a cylindrical thread guide channel 27 into which, contrary to the leno thread withdrawal, the outlet opening of an injector nozzle 29 opens.
  • the injector nozzle 29 is connected to a pneumatic control 30, comprising an electromagnetic control valve 30b, via a pressure line 30a connected to a pressure accumulator (not shown).
  • the control valve 30b is connected via the control line 30c to the programmable logic controller 3 of the weaving machine in a signal-transmitting manner.
  • the motor 5 is also connected to the controller 3 in a signal-transmitting manner via a control line 5a. It can thus be achieved that the leno threads 9, 10 can be acted upon pneumatically at least at the same time as the leno shed change and a corresponding tensile stress can be generated on the leno threads.
  • a mechanically acting leno thread tensioning device 26 is disclosed in FIGS. 3 and 4. Both devices have at least one thread deflection means 32 arranged in the running direction 31 of the leno threads 9, 10.
  • the deflection means 32 is operatively connected to a motor drive 33.
  • the drive 33 is connected to the controller 3 in a signal-transmitting manner via a control line 33a. Due to the constant delivery of electrical control signals to the drive 33, the leno threads 9, 10 can be deflected in the direction of the double arrow 40 by moving the deflecting means 32 and thus a tensile stress can be imposed on the leno threads, which ensures that the leno pocket is correctly and chronologically formed becomes.
  • Figure 4 shows the same technical structure as Figure 3, but here the deflection means 32 is connected to a permanently acting clamping element.
  • the tensioning element here is, for example, a pre-tensioned spiral spring 34.
  • the deflection element 32 is uncontrolled in FIG. 4 and therefore constantly acts on the leno threads in the sense of tensioning.
