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 spools usually still have residual turns in the area of the first winding layer after they have been exchanged for full spools. This is due to the need for a new roving to be put on in good time in order to avoid an interruption in the spinning process and thus a loss in efficiency.
  • 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.
  • it is necessary, in addition to the annular adhesive strip in the area Apply additional adhesive strips to the core of the roving on the core of the tube. This is necessary because the adhesive ring is only effective in the winding area if there are enough remaining turns that extend into this area (as shown).
  • the object of the invention is to provide a simple safeguard against unwinding of the roving turns still on the spool, which acts regardless 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 major part of the coil length that can be wound and its Width, seen in the circumferential direction of the coil, is less than half the circumference of the coil.
  • the adhesive strip protruding beyond the circumferential surface of the coil.
  • the part of the adhesive strip projecting beyond the circumferential surface of the coil can be, for example, the tips of protruding fibers attached to a base fabric of the adhesive strip.
  • a textile fabric with outwardly projecting fibers 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 with respect 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. Due to 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. 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.
  • the principle of the used fuse protection works as described below:
  • 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 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 upwardly directed 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 their position.
  • the nature of the adhesive strip is chosen so that other influences, such as, for example, 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 selected 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. In order to avoid this, 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 and also 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.

Claims (9)

  1. Fuseau de bobine (1) pour une bobine de mèche avec un fuseau essentiellement cylindrique possédant une partie de base (2), et avec des moyens servant à empêcher ou a éviter l'enroulement de spires résiduelles (14) restées sur le fuseau après le processus de débobinage,
    caractérisé par le fait que
    les moyens sont constitués par au moins une bandelette adhésive (9) formée d'une manière continue ou interrompue dans le sens de l'axe longitudinal du fuseau de bobine, bandelette qui s'étend sur au moins la majeure partie de la longueur de bobine pouvant être bobinée, et dont la largeur (B), vue dans le sens circonférentiel du fuseau de bobine (1), s'élève a moins de la moitié de la circonférence du fuseau de bobine.
