Definitions

  • the present invention relates to a method and a device for winding and evacuating the locks of waste originating from the cutting of the false edges of one or more widths during the weaving operation.
  • the wicks can for example be called by pinching between two toothed or rough wheels rotating at constant speed, then falling to the ground or into a pot; generally the loom has a pair of wheels for each bit.
  • Patent FR 2 076 557 describes a device for evacuating strands of waste from the cutting of false selvedges which comprises: a winding means of the wire delivery type, analogous to a reel, the perimeter of which varies along the generator; and means for braking (or driving) the coil.
  • the present invention provides a method and a device capable of automatically balancing the tensions of the locks.
  • the method for removing the locks of waste from the cutting of false edges is characterized in that a single cord formed from the locks undergoes a false twist, producing a winding of the locks with respect to each other, which allows their tensions to be automatically balanced, the cord thus formed is then wound up in the form of successive turns.
  • the device according to the invention mainly comprises a supply duct (2), a winding means (3) and a braking means (9).
  • the winding means (3) consists, without limitation, of a dispenser having a substantially concave area (3a) and a substantially convex area (3b) (see FIG. 1), with the aim of promoting the elimination of the turns which are form around the winding means as described below.
  • any other type of winding means fulfilling the same function may be suitable: a coil composed of two parts of different taper, or composed of a cylindrical part and a plurality of needles or bars kept inclined relative to the cylindrical part at by means of a cheek, according to a technique known in the frame debtors.
  • Said winding means (3) is for example made of plastic and mounted for free rotation on a shaft (4).
  • the supply duct (2) is for example composed of a circular cross-section tube, bent, so that a part (2a) is in the axis of rotation of the shaft (4) and that a part (2b) extends to the periphery of the winding means.
  • the outlet of the supply duct (2) is located on the side of the largest perimeter of the winding means and outside of it.
  • the supply duct (2) is furthermore driven in rotation by any suitable means, for example and without limitation by a speed multiplier assembly (7) with gears driven by the shaft of the fabric take-up roller not shown.
  • the braking means (9) of the preferred embodiment of the invention is composed of two bars (9a) arranged on either side of the deliverer (3) and extending perpendicular to the axis of rotation of the device, and able to clamp the turns against the coil (see diagram in Figure 2).
  • a braking means of another type for example of the magnetic type.
  • a cord (1) formed of at least two wicks (1 a) and (1 b) from the cutting of the two false edges of a width is introduced into the conduit (2) through the inlet (6), exits through the orifice (5) of said conduit (2), is deposited on the winding means (3) in the vicinity of its largest perimeter.
  • a cord (1) formed of at least two wicks (1 a) and (1 b) from the cutting of the two false edges of a width
  • said cord (1) undergoes a false twist which produces a winding of the locks relative to each other then it is deposited on the winding means (3) in the form of successive turns which, under the effect of the taper or the slope of the part (3b), and in a manner known per se, slide towards the zone of smaller perimeter (3a) where they are distributed substantially in the form at least one layer of turns.
  • This layer of turns is maintained by the braking means (9), then evacuated into a recovery container (8), automatically and fa lesson known per se, on the side of the smallest perimeter of the winding means (3).
  • the braking means also has the function of determining the resulting tension on the cord (1).
  • the wick (1b) is wrapped around the wick (1a) until there is catching up the lengths and that the tensions of the two locks rebalance.
  • the operation is all the better as the rotation speed of the duct (2) is greater than that of the fabric take-up roller, because the false twist of the cord is greater and the regulation better.
  • the device according to the invention has the advantage of being self-priming, an advantage which is not found in the devices known from the prior art.

1. Verfahren zum Abziehen des beim Beschneiden von falschen Webkanten anfallenden Fadenabfalls, welches eine Phase des spiralförmigen Zusammenrollens des Fadenabfalls und eine Abzugsphase aufweist, dadurch gekennzeichnet, daß die aus dem Fadenabfall gebildete einzige Schnur einen Falschdrall erhält, welcher einen Abzug des fortlaufend anfallenden Fadenabfalls bewirkt und automatisch ihre Spannung im Gleichgewicht hält und daß die so gebildete Schnur sogleich in aufeinanderfolgenden spiralförmigen Windungen abgezogen wird.
2. Vorrichtung zur Durchführung des Verfahrens nach Anspruch 1, gekennzeichnet durch folgende Merkmale:
- ein Mittel zum Zusammenrollen (3) von der Art eines Fadenabnehmers, dessen Umfang von der Länge der Erzeugenden abweicht und
- ein Mittel zum Bremsen (9) des Abzugsmittels (3), welches dadurch gekennzeichnet ist, daß es im übrigen noch folgende Merkmale aufweist: - ein in Drehung versetzbares Führungsmittel (2) für die Schnur (1), weiches derart ausgebildet ist, daß es die Schnur (1) auf dem Abzugsmittel (3) im Bereich seines größeren Durchmessers ablegt und daß es der Schnur (1) einen Falschdrall vermittelt.
3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß das Abzugsmittel (3) eine konkave Zone (3a) und eine konvexe Zone (3b) aufweist.
4. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß das Bremsmittel (9) aus zwei Stäben (9a) besteht, welche sich federnd an dem Abzugsmittel (3) abstützen.
