Definitions

  • the invention relates to a method of manufacturing nets by knotting mesh yarns on a loom equipped with opposite templets with rotating cylinders furnished with spikes which ensure the transverse extension of the net at the exit from the knotting area.
  • a templet is a device which is placed on each side of a loom and is intended to retain the fabric as it is made, keeping it stretched in the width direction.
  • a net is a fabric with more or less large meshes. If a large mesh net hardly poses problems in this regard, having in fact little tendency to narrow in width from the knotting area of the threads forming them. mesh, it is not the same in the case of nets with small meshes, whose width decreases much from the confection.
  • templets arranged in the usual manner are not effective enough to keep a small mesh net wide, unless some tricky devices are used.
  • the invention aims to remedy the drawbacks set out above by increasing the efficiency of the templets.
  • the process which is the subject of the invention is characterized by the fact that the intensity of the tension applied by the templets on the edges of the net is adjusted at the exit from the knotting area.
  • Such a tilt adjustment makes it possible to increase the efficiency of the templets by increasing their action of widening the net, each cur exerting on the corresponding edge of the net a force directed towards the outside whose intensity is a function of the inclination given in the direction appropriate to the axis of the cylinder.
  • the method according to the invention thus uses templets with orientable cylinders whose axis makes an adjustable angle with the direction of the width of the net, while remaining parallel to the plane of the latter.
  • Templets of this kind are known from French Patent No. 1,037,803. But if, according to this patent, each templet has an orientable cylinder, the orientation that this cylinder receives is opposite to that used in the process according to the invention ; its purpose is not in fact to increase the transverse extension force of the templet, but to avoid an abrupt reduction in the width of the tissue downstream of another cylinder which provides the extension force and whose the axis is parallel to the direction of the width of the fabric.
  • the net loom used comprises a rear flat bar forming with an anterior flat bar an interval through which the net is evacuated downstream from the knotting area, the cylinder of each templet in an opening made at the corresponding end of the rear flat bar, the cylinder engaging the thread in the aforementioned interval.
  • the position of the cylinder is also adjustable in a direction perpendicular to the plane of the net and of said flat bars, this adjustment making it possible to move the cylinder more or less towards the front flat bar, in which is dug a cavity into which the cylinder can penetrate by forcing the corresponding edge of the net to pass there in a sinuous path. We can thus measure the meshing efficiency of the cylinder with the thread.
  • a templet for implementing the method according to the invention may comprise not a single cylinder, but a pair of cylinders furnished with spikes, with parallel axes, the assembly of the two cylinders being mounted on a frame oscillating around an axis parallel to the axes of the cylinders. This arrangement doubles the effectiveness of the templet.
  • the templet is in any case preferably designed so that its adjustment members are accessible, after mounting on the loom, from the rear of the aforementioned rear flat bar.
  • needles 5, 6 which, animated by suitable movements, ensure, in cooperation with other needles, not shown, the making of noueds of a net which is evacuated step by step in the interval 7 formed between two flat bars 8 and 9, which extend, like the rows formed by the needles, over the entire width of the loom.
  • the rear bar 8 can be covered, on the side of the gap 7, with a sheet 10.
  • a templet 11 is arranged at each end of the bars 8, 9.
  • This comprises a pair of cylinders 12 bristling with spikes, placed one above the other, which rotate freely on themselves around axial rods 13 fixed in a frame 14 oscillating around an axis 15 by means of pins 16 mounted in the arms 17a of a fixed support 17.
  • the rods 13 and the axis 15 are substantially oriented in the direction of the width of the net, that is to say perpendicular to the discharge direction 20 thereof ( Figure 2).
  • the cylinders 12 are housed in an opening 18 made in the rear bar 8 (and in the sheet 10), opposite which is hollowed in the front bar 9 a cavity 19, so that they engage by their points with the net in the interval 7.
  • the inclination of the axes of rotation of the cylinders 12 with respect to the direction of the width of the net can be adjusted by adjusting the angular position of the support 17.
  • the latter is in fact carried by a cross member 21 offering in its center a pivot 22 engaged in a corresponding hole in the rear bar 8, so that the angular position of the templet 11 can be adjusted so that it exerts on the net a more or less great pull towards the outside (according to arrow 23), this- ci being maximum when the templet is placed in the extreme position 11 ′, in which the axis 15 comes in 15 ′.
  • the shape given to the opening 18 and to the cavity 19 (visible in FIG. 2) allows the corresponding travel of the templet. After adjustment, the templet is immobilized by tightening two screws 24 for fixing to the bar 8 passing through two buttonholes made in the crosspiece 21.
  • the templet 11 is also adjustable in the direction perpendicular to the plane of the thread defined by the interval 7, so as to move the cylinders 12 more or less through the interval 7 in the cavity 19.
  • the support 17 can pivot relative to the cross member 21 about an axis defined by two pivots 25 and parallel to the axes of the cylinders 12. This adjustment is carried out with the acid of a rotary handle 26 terminated by a threaded rod 27 screwing through the lower part of the support 17 and pressing against the rear face of the rear bar 8, below the pivot axis of the support 17 on the cross member 21. After adjustment, the position of the templet is locked at the using a lock nut sleeve 28.
  • the cylinders 12 of the templet sink more or less into the edge of the net and can force it to follow a sinuous path in the cavity 19, which increases the efficiency of the templet, independently of the inclination given to it using the first setting.
  • each of the two adjustments is made on the rear side of the rear bar 8.
  • the templet represented is that which is arranged at the left end of the loom when viewed according to the arrow II.
  • the structure of the other templet, placed at the right end, is obviously symmetrical with respect to the median plane of symmetry of the loom.
