Definitions

  • the present invention relates to the field of the textile industry, in particular the benches with spindles for long fibers and more particularly the pressing finger forming an integral part of the fin and used for winding the wick on the spool, that is to say say used for the formation of the coil and has for its object such a pressing finger (DE-A-3 023 241, GB-A-459 672, US-A-1 569 534)
  • the object of the present invention is to propose improving the breakage of each wick.
  • a pressing finger for spindle benches characterized in that it is essentially provided with a slot opening at one end into the passage hole of the drill bit, closed at its other end and having a section transverse less than the diameter of the drill bit, the slot being arranged so that when the wick (6) is ruptured by a vertical displacement from the bottom to the top of the spool (5), the wick leaves the passage hole (2) and is received in the slot (1) to block.
  • the pressing finger 4 for pin banks is essentially provided with a slot 1, opening at one end into the hole of passage 2 of the wick 6, closed at its other end and having a cross section smaller than the diameter of the wick.
  • Such a breaking process has the advantage of avoiding breaking of the wick 6 inside the fin or on the pressing finger 4, which would cause discomfort for starting the winding of a new reel. Indeed, when restarting the machine, the wick 6 is pulled horizontally and thereby automatically leaves the slot 1 in order to return to its normal position shown in Figure 2, that is to say passing through hole 2.
  • the slot 1 has a conical shape ensuring automatic blocking of the wick 6 regardless of the size of the latter ( Figure 4).
  • FIG. 5 It is also possible, as shown in FIG. 5, to provide a slot 1 with parallel faces.
  • the faces of the slot 1 are machined at sharp angles, without burrs.
  • Such an embodiment of the faces of the slot 1 is intended to better ensure the blocking of the wick 6, without however hanging the fibers.
  • the pressing finger 4 is advantageously provided with a deflecting sheet 3.
  • a deflecting sheet 3 is intended to prevent the pressing finger 4 s 'grip in the turns of the coil 5 during vertical movement from bottom to top of the coil.
  • This sheet 3 thus slides, without catching, on the cone of the coil 5 and causes the opening of the pressing finger 4 despite the pulling of the wick 6.
  • the deflector plate 3 advantageously has a strong inclination relative to the vertical, in order to follow the slope of the cone of the coil while avoiding catching the turns of the latter and so as to favor the opening of the pressing finger 4.
  • the inclination of the deflector plate 3 relative to the vertical is preferably between 100 ° and 150 °.
  • the invention it is possible to produce a pressing finger for pin benches allowing easy breaking of the wick at the end of the winding operation, while ensuring the presence of one end of said wick under the pressing finger at the start of the winding operation of a new reel.

Claims (7)

  1. Preßfinger für Spindelbänke, dadurch gekennzeichnet, daß er im wesentlichen mit einem Spalt (1) versehen ist, der mit seinem einen Ende von dem Durchgangsloch (2) für die Lunte (6) ausgeht, an seinem anderen Ende geschlossen ist und einen transversalen Querschnitt aufweist, der kleiner ist als der Durchmesser der Lunte, wobei der Spalt so angeordnet ist, daß dann, wenn man die Lunte (6) dadurch abreißt, daß man die Spule (5) in vertikaler Richtung von oben nach unten bewegt, die Lunte das Durchgangsloch (2) verläßt und in dem Spalt (1) zu liegen kommt, wodurch man ein Festlegen erhält.
  2. Preßfinger nach Anspruch 2, dadurch gekennzeichnet, daß der Spalt (1) konische Gestalt aufweist, und so ein automatisches Blockieren der Lunte (6) unabhängig von der Abmessung der letzteren gewährleistet.
  3. Preßfinger nach Anspruch 1, dadurch gekennzeichnet, daß der Spalt (1) parallele Begrenzungsflächen aufweist.
  4. Preßfinger nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die Begrenzungsflächen des Spaltes (1) unter scharfen Winkeln angestellt sind, jedoch gratfrei gearbeitet sind.
  5. Preßfinger nach Anspruch 1, dadurch gekennzeichnet, daß er vorzugsweise mit einem Ablenkblech (3) versehen ist.
  6. Preßfinger nach Anspruch 5, dadurch gekennzeichnet, daß das Ablenkblech (3) vorzugsweise eine starke Neigung zur Vertikalen aufweist, damit es sich der Neigung des Kegels der Spule anpaßt, wodurch verhindert wird, daß es sich an den Windungen der letzteren verhakt, und ein Öffnen des Preßfingers (4) gegünstigt wird.
  7. Preßfinger nach Anspruch 5 oder 6, dadurch gekennzeichnet, daß die Neigung des Ablenkbleches (3) zur Vertikalen vorzugsweise zwischen 100° und 150° beträgt.
