Definitions

  • double-wire twisting spindles of which the two single threads drawn from the supply bobbins are jointly inserted into the upper end of the thread inlet tube
  • double-wire twisting spindles are also known for the double attachment of two feed bobbins, which have two thread inlet tubes one above the other, in which the two of them the individual threads drawn off from the two supply spools are inserted separately from each other above the associated supply spool into the thread inlet tube (see DE-AS 12 27 367).
  • DE-AS 19 32 941 describes a double-wire twisting spindle which, for the double attachment of two supply bobbins, has two thread inlet pipes one above the other, in which the two single threads drawn from the two supply bobbins are also separated from each other above the associated supply bobbin in the respective one Thread inlet pipe are introduced.
  • a further spring-loaded brake element is attached to the thread drawn off the lower supply spool at the lower end of the upper thread inlet tube, which is equipped with a thread brake for the thread of the upper supply spool, which is attached during operation the double-wire twisting spindle is pressed against the upper end of the lower thread inlet tube with a defined braking force.
  • This document does not contain any information about the type of threading itself, and in particular it does not contain any information about pneumatic threading.
  • DE 24 61 796 C2 describes a double-wire twisting spindle with a compressed air-operated threading device arranged in the region of the hollow spindle axis, with which the thread is sucked into the hollow spindle axis by injector action and is conveyed by the compressed air jet through the thread guide channel of the thread storage disc.
  • the thread brake In order to enable a corresponding pneumatic threading in a double-wire twisting spindle which is equipped with a thread brake, it is known from DE 29 14 656 C2, the thread brake to be designed such that the compressed air supplied to the pneumatic threading device is simultaneously used to open or vent the thread brake to form a free thread threading path.
  • the pneumatic threading could be carried out with a threading device according to DE 24 61 796 C2 can be done in the following way:
  • the bobbin including the bobbin carrying the lower template is placed on the double-wire twisting spindle, and the thread is then threaded or threaded through the end of the thread coming from this lower bobbin to the associated thread inlet opening and by applying pressure to the pneumatic threading device.
  • the thread then passes through a so-called thread wing, which advantageously influences the thread draw-off from the supply spool.
  • the thread of the upper bobbin were to be pneumatically threaded, as is known, without considering the already threaded thread of the lower supply bobbin, then the thread of the lower supply bobbin would be further drawn off by the injector air flow, whereby the twisted wing of the lower supply bobbin is inevitably set in rotation.
  • the thread wing of the lower supply spool would continue to run a little due to its inertia. This would result in further thread being drawn off, which would lead to the thread being twisted or tangled in the twisted wing eyelet.
  • a thread break would inevitably be programmed when the spindle starts up.
  • the thread end drawn off from the upper supply spool is then attached to the upper end of the thread inlet tube of the upper supply spool, in order to then be threaded through the overall system together with the thread located in the same place and coming from the lower supply spool by means of a second pneumatic threading device.
  • the inlet tube of the upper supply bobbin can be moved downwards, on the one hand to actuate the first injector for threading the thread coming from the lower feed bobbin through the upper thread inlet tube, and on the other hand, when threading both threads together by means of the second threading device, one in the area of the lower feed bobbin to open the existing thread brake mechanically.
  • the thread threading process is also complex.
  • the invention has for its object to provide a simplified threading method.
  • the device according to claim 5 is a simple construction of an auxiliary unit for threading the thread of the second supply bobbin through the thread inlet tube assigned to this second supply bobbin as an accompanying or preparatory measure for carrying out the method according to the invention.
  • Figures 1 and 2 show partially in section side views of a double-wire twisting spindle in the course of two successive process steps for performing the method according to the invention.
  • the double-wire twisting machine 1 shown schematically in FIG. 1 contains a spindle bench 2 and a machine front wall 3 to which a guide rail 4 for a carriage 5 movable in the direction of the double arrow f1 is fastened.
  • a large number of double-wire twisting spindles 6 are stored next to one another, of which only one spindle is shown in FIGS.
  • Each individual spindle 6 comprises a whorl 7, a thread storage disk 8 and a protective pot 9 which is secured against rotation by means of magnets, not shown.
  • Each spindle also contains a balloon limiter 10.
  • a separator wall 11 is provided between adjacent spindles.
  • a thread inlet tube 12 is assigned to the bobbin 9 in the usual way.
  • a first supply spool A is inserted into the twisting spindle to populate each individual double-wire twisting spindle 6.
  • the free thread end a of the first supply spool A which is passed through the twisted wing eyelet 13, is drawn off from this supply spool and is preferably clamped in a thread clamping element 14 which is attached in the region of the upper balloon limiter edge on the front of the machine.
  • a threading auxiliary unit preferably in the form of a bobbin and supply bobbin holder 15, is attached to the slide 5.
  • This cold 15 contains a hollow arbor 16, which is provided with a continuous axial slot 16 ', to which an essentially radially directed slot 17' adjoins in the area of a supply spool support surface 17.
  • the support surface 17 is fastened to the upper end of a cabbage body 18 which contains, in a manner not shown, an injector-like threading device which can be actuated by compressed air and which can be supplied with compressed air via a compressed air connection 19.
  • a second supply spool B is plugged in accordance with arrow f2 with the protective pot 21 receiving it and having a thread inlet tube 20 onto the hollow arbor 16 of the bobbin pot and supply bobbin holder 15 which can be moved along the guide rail 4 and which has been brought into the area of the double-wire twisting spindle 6 to be maintained is.
  • the thread drawn off from the supply spool B and threaded through the twisted wing eyelet 22 is then preferably threaded through the thread inlet pipe 20 and the hollow plug-in mandrel 16 by actuating the pressure medium-actuated device, not shown, so that the free thread end b emerging in the direction of the arrow f3 is gripped by hand can.
  • This thread end b is brought together with the thread end a fixed in the region of the clamping element 14, and these two thread ends a and b are placed against the thread inlet opening of the thread inlet tube 12 assigned to the lower supply bobbin A.
  • a known compressed air-operated threading device arranged in the region of the spindle hollow axis section assigned to the lower feed bobbin is then pressurized with compressed air, so that the two thread ends are threaded in the manner shown in FIG. 2 through the lower spindle hollow axis section assigned to the lower feed bobbin A and the thread guide channel 8 'and then are conveyed upwards into the gap between the lower coil pot 9 and the balloon limiter 10, as is shown in FIG.
  • the thread ends threaded in this way are then tightened, while the upper supply bobbin B, together with the spindle pot 21, is lifted off the bobbin pot and bobbin holder 15 and in the direction of arrow f4 in the manner shown in FIG. 2 from above onto the upper edge of the lower bobbin 9 be lowered.
  • the axial and radial slots 16 'and 17' enable the thread b to be guided out of the bobbin and supply bobbin holder 15.
