Definitions

  • the invention relates to a device for winding at least one synthetic thread, in particular on a stretch winder, with a rotatable bobbin tube, a driven friction roller touching the outer circumference of the bobbin tube, a traversing device for the synthetic thread and a collar rotating synchronously with the bobbin tube larger diameter than the coil sleeve.
  • the friction roller on which the thread bobbin bears for driving, has a collar in the region next to the thread winding with a slightly larger diameter than the friction roller, which presses against the bobbin tube. This will make the coil driven at a greater peripheral speed than would correspond to the normal diameter of the friction roller. Accordingly, it pulls the thread faster while increasing the thread tension. With increasing wind diameter, the thread take-off speed increases even further until the winding has grown to the friction roller and the drive of the bobbin changes to the normal diameter of the friction roller (DE-OS 24 32 166).
  • the thread wound under these conditions which can be several 1000 m, disadvantageously differs in its properties from the thread of normal production.
  • the prior art discloses a device for winding textured yarns on bobbins, in which a ring is placed as a collar on the sleeve of the bobbin to be wound, which ring has a smaller outer diameter than the finished bobbin (DE- PS 17 60 758).
  • This collar is in frictional engagement with the friction roller, the peripheral speed of the bobbin being smaller than that of the friction roller. It increases as the bobbin grows until the friction roller and the collar separate from one another and the friction roller in turn comes into frictional engagement with the bobbin itself to then remain constant. This inevitably results in the inner layers being loosely wound in the finished coil than the outer ones. It follows that the thread tension at the beginning of the winding process on a bobbin tube is less than during the subsequent winding.
  • the present invention has for its object to provide a device of the type mentioned, which ensures that the thread tension is increased for a short time after placing a thread.
  • the collar is arranged next to the friction jacket of the friction roller and is designed to accommodate the initial length of the synthetic thread and that the bobbin tube is associated with a thread guide device for guiding the thread running onto the bundle in the region of the bobbin tube. This results in a simple increase in thread tension.
  • the diameter of the coil can be 1 to 10% larger than that of the coil sleeve.
  • the collar can be plugged onto the spool sleeve, or it can be fixed or detachably connected to a sleeve holder that supports the spool sleeve.
  • the thread guide device can have at least one first movable guide edge arranged perpendicular to the longitudinal axis of the bobbin and at least one second fixed guide edge which runs partially parallel to the longitudinal axis of the bobbin. The interaction of the fixed and movable guide edges ensures that the thread is guided from the collar into the winding area.
  • the thread guide device can have a second movable guide edge in the area of the transfer winding parallel to the first guide edge.
  • the invention can advantageously also be used for unwinding two synthetic threads.
  • the bundle is designed to accommodate the initial length of the two synthetic threads, the two threads running onto the bundle being movable into two separate regions of the bobbin tube by the thread guide device.
  • the thread guide device can have a fixed guide edge holding both incoming threads and at least one movable guide edge releasing both threads and one in each of the two areas of the bobbin tube have movable and a fixed leading edge.
  • the movable guide edges can be folded out of the effective area and / or can be moved out linearly.
  • the guide edges can be formed, for example, by wire brackets or by edges of flat parts, such as metal sheets.
  • a device for winding a synthetic thread 5 is shown in a schematic plan view.
  • a coil sleeve 1 is used, which is arranged on a rotatable sleeve holder 2.
  • the bobbin tube is acted upon on the outer circumference by a friction roller 3, which interacts with a traversing device 4, which winds the thread 5 onto the winding area 13 of the rotatable bobbin tube 1.
  • the coil sleeve 1 or the sleeve holder 2 is provided with a collar 6 which is arranged next to the friction jacket of the friction roller 3 and has a (slightly) larger diameter than that of the coil sleeve 1.
  • This collar 6 thus protrudes into the area of the friction roller 3 without contact. It is provided for receiving an initial length 20 of the synthetic thread 5.
  • the diameter of the collar is approximately 1 to 10% larger than that of the coil sleeve 1, preferably between 1 to 3%.
  • the collar that can be rotated with the sleeve in any case can either be plugged onto the coil sleeve 1; there are alternatively also the possibilities that the collar 6 is fixed or detachably connected to the sleeve receptacle 2.
  • the collar 6 is provided with a thread catcher 7 known per se, for example in the form of a slot.
  • the collar 6 cooperates with a thread guide device 8.
  • This thread guide device 8 serves to move the thread wound on the bundle 6 into the winding area 13.
  • the thread guide device 8 has a first movable guide edge arranged perpendicular to the longitudinal axis A-A of the spool, e.g. a pin 9 and at least one fixed guide edge running at least partially parallel to the coil longitudinal axis A-A, e.g. a bracket 10 on.
  • the pin 9 holds the incoming thread 5 in the region of the federal government 6.
  • the movable pin 9 is withdrawn via a controlled drive, not shown, so that the thread 5 thereby passes into the winding area 13 of the bobbin tube 1.
  • a transmission winding 11 between the winding area 13 and the collar 6.
  • a second movable guide edge for example a second pin 12, arranged parallel to the first guide edge, ie the pin 9, is provided.
  • the second pin 12 is also retracted, as shown in FIG. 2c, so that the synthetic thread 5 passes along the bracket 12 into the area of the traversing device 4, is gripped by it and is wound in an alternating manner in the winding area 13.
  • the fixed bracket 10 is advantageously slightly angled in the rear area, so that an easier insertion of the synthetic thread 5 into the traversing device 4 is accomplished.
  • the device according to the invention can also be used to wind up two synthetic threads according to FIGS. 3 to 5.
  • Fig. 3 shows that the collar 6 is designed to accommodate the initial length 20 of two synthetic threads 5, 5 '. Again, both threads 5 and 5 'are caught on the bundle 6 with the aid of the thread catching device 7 and then an initial length 20 is wound on the bundle 6. Both threads 5 and 5 'in turn receive an increased thread tension due to the larger diameter of the federal government.
  • the two threads 5 and 5 ' are threaded with the help of the thread guide device 8' (FIG. 4, FIG. 5). led into the respective area of a transmission winding 11 and 11 'and later into the winding area 13 and. 13 '.
  • the thread guide device 8 ' according to FIG. 4a has a fixed guide edge 14 in the form of a hook in the region of the federal government 6.
  • the thread 5 also lies in front of a second movable guide edge 16.
  • the pin 15 is pulled out of the effective area according to FIG. 4b, so that both threads 5, 5' are released.
  • the thread 5 ' thus comes into contact with a movable leading edge, e.g. a pin 16 ', which is located in the area of the transmission winding 11'.
  • the first thread 5 is only in contact with the movable pin 16, which in turn is also located in the area of the first transmission winding 11 assigned to it.
  • the movable guide edges 16 and 16 ' are moved out of the effective range of the two threads 5 and 5', so that the threads 5 and 5 'only rest against fixed guide edges in the form of brackets 17 and 17' and thus reach the area of the traversing devices 4 and 4 '(FIG. 3). You are thus in the winding area 13, 13 '.
  • the present invention ensures in a simple manner that immediately after placing a thread 5, or two threads 5 and 5 ', the thread tension is increased by - in contrast to the prior art with a drive collar - a winding collar 6 is used, which one has a larger diameter than that of the coil sleeve 1.
  • the present invention is also suitable for trifilar running threads, a bundle 6 again being used for the three threads and the thread guide device being equipped with corresponding movable and fixed guide edges for producing a start-up winding, a transition winding is before the three threads get into the respective winding area.
