Definitions

  • the invention relates to a weaving machine according to the preamble of claim 1.
  • This weaving machine has a weaving station, which is followed by a spreading device for the web to be produced.
  • the spreader device contains a deflecting edge for the web against which a floating, freely rotatable round rod, which extends over the entire width of the web, is biased.
  • the round bar is arranged in a recess in a machine frame which contains a slot which forms an incoming and an outgoing deflection edge for the material web. The material web must therefore be inserted into the slot, guided around the round bar and led out again via the second deflection edge at the slot.
  • the pretension with which the round bar is pressed against the deflection edges is determined by the tension on the web on the take-off device of the weaving machine.
  • This design of the spreader has the disadvantage that the insertion of the material web through the slot into the recess, the looping of the round rod and the execution of the material web from the recess is very complicated and cumbersome. This is not only for setting up the weaving machine, but in particular also for the removal of any malfunction in the weaving machine.
  • the object of the invention is to improve a weaving machine of the type mentioned at the outset so that the disadvantages mentioned no longer occur.
  • the object is achieved in the loom mentioned at the outset by the characterizing features of claim 1.
  • the round bar is biased against the deflection edge by means of magnets distributed over its length
  • the arrangement of the round rod in a recess with a slot can be omitted and the round rod is freely accessible on the web. It also no longer has to be pressed against the deflection edge by means of the pulling force of the material web, but rather this is due to the magnetic force which prestresses the round bar against the deflection edge.
  • the round bar can be removed from the machine frame for adjustment work and / or repairs, so that the web is freely accessible at all times.
  • the magnets distributed over the length of the round rod provide a uniform contact force over the entire length.
  • the magnets for biasing the round bar magnets can be electromagnets according to claim 2. These have the advantage that they can be switched on and off on the one hand, which makes it easier to remove the round rod. On the other hand, the field strength of the magnets can be adjusted within wide limits with the aid of the current, as a result of which the spreading device can be optimally adjusted to the fabric and the type of manufacture.
  • a design of the weaving machine according to claim 3 is particularly simple, according to which the magnets are permanent magnets, which ensure a particularly simple construction and are also effective when no drive current is present.
  • the pressing force of the magnets is greater than the pulling force exerted on the web by a pulling device.
  • the contact pressure of the magnets may also be less than the pulling force of the pulling device. It may be appropriate for the support rollers to be biased against the round bar. To facilitate assembly and the adjustment and maintenance of the weaving machine, the support rollers can also be swung out.
  • the round bar can be provided with a rubber-elastic sheathing, or according to claim 7 with a sandpaper-like sheathing.
  • the round rod can be provided with a helically profiled sheathing, the helical profile being oriented in opposite directions on both halves of the round rod.
  • Such a round rod expediently interacts with a smooth deflection edge and serves to stretch the continuous fabric web on both sides.
  • the deflection edge is provided with ribs which - seen in the running direction of the web, run obliquely outwards on both sides of the center line.
  • the round rod expediently does not have a helically profiled casing.
  • Figure 1 shows the schematic of a loom in vertical section
  • FIG. 2 shows a deflection edge that can be used in the weaving machine of FIG. 1;
  • Figure 3 shows a round rod with a helically profiled casing
  • FIG 1 shows a schematic representation of a loom in detail. Warp threads 2 form a shed 4 into which a weft thread 6 is inserted. The Weft thread 6 is then attached to the fabric stop edge 10 by means of a reed 8.
  • the goods stop edge 10 is followed by a spreading device 12 which has a deflection edge 14 against which the fabric web 16 produced is pressed by means of a round rod 18.
  • the round rod 18 made of ferromagnetic material is pressed against the deflection edge 14 by means of magnets 20, so that the web 16 guided over the deflection edge 14 is brought into contact with the round rod 18, so that the web 16 driven by a take-off device 22 den Round rod 18 set in rotation.
  • the round bar is arranged floating on a machine frame 24 and freely rotatable. Several magnets arranged over the length of the round rod and fastened to the machine frame 24 ensure the necessary contact pressure. The contact pressure is greater than the pulling force of the pulling device exerted on the web.
  • the round rod 18 in the present example consists of a ferromagnetic core 26 which is surrounded by a sheath 28 which is made of rubber-elastic material.
  • a sheath 28 which is made of rubber-elastic material.
  • another sheathing can also be provided, which increases the frictional resistance between the web 16 and the round rod 18.
  • Such a covering can consist, for example, of sandpaper.
  • the deflecting edge 14 cooperating with the round rod 18 is provided according to FIG. 2 with ribs 30 which, seen in the direction of travel of the web 16, run obliquely outwards on both sides of the center line 32.
  • FIG. 3 shows a round rod 18a which is provided with a helically profiled casing 28a which has helical ribs 34 which are oriented in opposite directions on both halves of the round rod 18a.
  • a round rod 18a expediently interacts with a smooth deflection edge 14 in order to stretch the continuous material web transversely to the longitudinal direction.
  • support rollers 36 can be assigned to the round rod at least at its ends, possibly also distributed over its length.
  • the support rollers 36 are each arranged on a boom 38 which can be swung out and in on the machine frame 24.
  • the arms 38 contain an elongated hole 40 for the axis 42 of the support roller 36.
  • Springs 44 act on the axis 42 for prestressing the support rollers 36 against the round rod 18.

Abstract

L'invention concerne un métier mécanique présentant un dispositif templet (12) implanté en aval d'un point de tissage (10) et destiné à la nappe de tissu (16) à produire. Ce dispositif templet comprend un bord de détour (14) qui est destiné à la nappe de tissu (16) et sur lequel une barre ronde (18) exerce une pression de contrainte, cette barre étant librement rotative, placée de manière flottante et couvrant toute la largeur de la nappe de tissu. Pour un accès simple et amélioré, la barre ronde (18) est constituée au moins partiellement de matériau ferromagnétique et exerce une pression de contrainte sur le bord de détour (14) à l'aide d'aimants (20) qui sont logés dans le bâti de machine (24) et sont répartis sur la longueur de la barre.
