Definitions

  • the invention relates to a bobbin tube for a roving bobbin with a substantially cylindrical tube with a foot part and with means for preventing or preventing the unwinding of residual windings remaining on the tube after the unwinding process.
  • the sleeves of the empty bobbins usually have residual turns in the area of the first winding layer after they have been exchanged for full bobbins. This is due to the need for a new roving to be set in good time in order to avoid an interruption in the spinning process and thus a loss of the useful effect.
  • the remaining turns on the sleeve can still extend over the entire length of the sleeve or over only part of the length.
  • a device is also known from Japanese Utility Model No. 58-158065 (FIGS. 5.8), the remaining turns of the roving being secured against detachment by means of adhesive strips attached to the sleeve and the sleeve base.
  • the adhesive strips are attached in the circumferential direction on a short section with respect to the longitudinal axis of the sleeve.
  • the object of the invention is to provide a simple safeguard against unwinding of the roving turns still on the spool, which acts independently of the number of remaining turns of the roving still on the sleeve and does not impair a subsequent cleaning process of the sleeve.
  • means which consist of at least one adhesive strip attached in the direction of the longitudinal axis of the coil, which extends over at least the largest part of the coil length which can be wound and whose width, viewed in the circumferential direction of the coil, is less than half the circumference of the coil is.
  • the part of the adhesive strip protruding over the circumferential surface of the spool can be, for example, the tips of protruding fibers attached to a base fabric of the adhesive strip.
  • a textile fabric with fibers protruding outwards for the adhesive strip which has a greater adhesive force in the brushing direction against the sleeve base than in the opposite direction.
  • the fibers protruding from a textile base fabric are oriented obliquely in relation to the longitudinal axis of the sleeve and in the opposite direction to the sleeve base.
  • Such a textile fabric with protruding fibers is already known for use as an attachment aid on the sleeve. Due to the proposed mode of operation of the adhesive strip, the cleaning device could be adapted in its movement sequence accordingly, in order to ensure proper cleaning of the sleeve.
  • attachment aid and adhesive strips enables the simultaneous application of these strips on the sleeve in the same operation.
  • the adhesive strip As a rule, it is sufficient to form the adhesive strip between 3 and 10 mm wide. Because of this narrow design, the subsequent cleaning process is made easier. In addition, only a few fibers are retained by the adhesive strip when the roving is unwound.
  • FIG. 1 shows a coil sleeve 1 with a coil foot 2 which has a driving groove 3.
  • the coil 1 is provided with an attachment aid 5 which is applied and fastened in an annular groove 6.
  • the sleeve 1 is hollow on the inside and has an inwardly projecting flange 7 in the area of the head 4, which serves to hang the sleeve on a hanging pin 8, and in FIG. 4 is shown schematically.
  • the sleeve is provided with an adhesive strip 9 which is inserted and fastened in a longitudinal groove 10 (FIG. 2).
  • the longitudinal groove 10 runs coaxially with the longitudinal center axis of the sleeve 1.
  • the adhesive strip 9 or the longitudinal groove 10 have a small width B, for example of only 5 mm.
  • the adhesive strip 9 consists of a textile base fabric 11 in which fibers 12 projecting outwards are anchored.
  • the fibers 12 are oriented obliquely, as seen transversely to the longitudinal center plane of the bobbin 1, their tips being oriented in the direction of the bobbin head 4.
  • the fiber tips of the fibers 12 project beyond the circumferential surface 13 of the coil 1 by the dimension X.
  • FIG. 4 there are residual turns 14 of a roving 15 on the sleeve 1 shown.
  • the roving end 16 is located in the region of the foot 2.
  • the state of a sleeve 1 shown in FIG. 4 can correspond, for example, to the state after a bobbin change. However, it is also possible that the remaining turns 14 of the roving 15 remaining on the bobbin 1 still extend over the entire bobbin length.
  • Fig. 5 shows a further embodiment variant, wherein instead of a stick-on adhesive strip e.g. sawtooth-like elevations 21 are integrated into the surface on a sleeve section or strip 20.
  • a stick-on adhesive strip e.g. sawtooth-like elevations 21 are integrated into the surface on a sleeve section or strip 20.
  • These elevations which are shown on an enlarged scale in FIG. 6, can be included in the sleeve production at the same time, or can be injected at the same time.
  • the shape of the elevations is not limited to the sawtooth shape and can also be designed differently. They However, must not exceed a certain size, so that no roving damage occurs. From DE-OS 32 29 449, for example, designs of such teeth or serrations can be found, which are molded directly onto the sleeve. In this version, however, they serve as a positioning aid and are arranged in a ring.
  • elevations can also be applied by subsequent spraying or by other application methods onto the sleeve surface.
  • the invention relates essentially to the cases in which there is only a first turn layer.
  • the fuse 15 of the bobbin 1 suspended in a spinning machine creel (not shown) is manually or automatically separated between the bobbin and a subsequent drafting unit of a spinning machine, not shown, when there is only a certain remaining amount of remaining turns on the bobbin.
  • the separated roving end 16 bears against the sleeve base 2 according to FIG. 4 due to its gravity.
  • the first turn of the remaining turns 14 is at a distance Z from the sleeve base 2
  • the roving 15 adheres to the area of the adhesive strip 9, which prevents further loosening of the remaining turns 14.
  • the upward fibers 12 of the adhesive strip 9 counteract the downward gravity of the roving 15 and hold the first turn of the remaining turns 14 in position.
  • the nature of the adhesive strip is chosen so that other influences, such as uncontrolled air currents, do not lead to the detachment of the remaining turns 14.
  • the adhesive force between the fuse 15 and the adhesive strip 9 should only be chosen so large that no damage to the roving 15 occurs during the unwinding process during the spinning process of the first winding layer, for example from the region Z. Damage would inevitably lead to yarn defects in the subsequent spinning process.
  • the width B of the adhesive strip is kept relatively small.
  • the subsequent cleaning of the sleeve 1 or the removal of the remaining windings 14 can be easily removed.
  • the cleaning process could be adjusted according to the fiber direction of the fibers 12. This means that a cleaning roller can be moved in the direction of the head 4 when the remaining turns 14 are detached, since the adhesive strip 9 exerts a lower adhesive force in this direction.
  • the adhesive strip 9 or the attachment aid 5 can be glued in or attached in some other way.
  • the embodiment shown enables simple and inexpensive fuse protection, which on the one hand ensures that the remaining turns on the spool 1 are held securely and on the other hand prevents roving damage and does not lead to any restrictions in the subsequent cleaning process.
