Definitions

  • the invention relates to a device for training the crowd for the realization of a selvedge and a loom equipped with such a device.
  • a loom makes it possible to make a fabric on a width which can be important by forming a pattern or weave thanks to an appropriate device, in particular a mechanical Jacquard or dobby.
  • the side edges of the current fabric training most often called selvedges, are trained with the fabric and are likely to fray. It is known to use a cam system to control beams specific for side chain wires. he is also known, for example from FR-A-2 685 014, to use a mechanical Jacquard specific for the realization of a selvedge on a fabric being woven.
  • Such a Jacquard mechanic is relatively complex and requires its mechanical connection to a main drive shaft, which involves mounting a like a tree at a distance from a driving tree of the trade.
  • a Jacquard mechanics is a relatively sophisticated system which is not necessarily suitable for the simplest cases in which a selvedge with a substantially uniform pattern must be created.
  • EP-A-0 750 061 proposes a device for the realization a false selvedge with no gauze which does not allow weaving a real selvedge because it only includes two smooth associated with a smooth panty, these smooth being mounted in overhang on a belt and mechanically stressed in permanence. Relatively massive beams should be used, their inertia and rigidity not being compatible with the weaving of a selvedge.
  • the invention aims to propose a device for training the crowd for a real edge of simple construction, so reliable, and which does not necessarily have to be connected to a driving force of the trade.
  • the invention relates to a device for crowd training for the realization of a selvedge on a fabric being produced on a loom, characterized in that it comprises two frames each carrying several smooth and provided with longitudinal edges and upper edges and lower. These frames are moved, according to a movement substantially vertical alternating in phase opposition, by at least one flexible link actuated by an electric motor and connected to their upper or lower edges.
  • the two heald frames allow to order the movement of the chain son from one loom to weave in a simple weave movement adapted to the selvedges and this, thanks to the electric motor which must be connected to a control power supply unit by electrical connection significantly easier to install than a drive shaft.
  • the use of heald frames makes it possible to order heald parallel in sufficient number for weaving corresponding to the width of a standard selvedge, the frames allowing precise positioning of the beams, then that they effectively resist the efforts transmitted to them by the flexible link.
  • This link flexible can be a belt, chain or equivalent.
  • the electric motor can be easily controlled, so that the movement of the heald frames is out of phase with respect to to that of the main crowd training device of the craft, whether dobby frames or harnesses Jacquard.
  • the invention finally relates to a loom equipped with minus a device as previously described.
  • a weaving loom includes a device such as previously described at each edge of the fabric in manufacturing course.
  • the loom shown in Figure 1 includes several heald frames 1 arranged parallel to each other others and having beams 2, the eyelets 3 of which are provided to guide chain wires 4.
  • Each frame 1 is controlled, as shown only for the first frame visible in FIG. 1, by connecting rods 5 integral with return levers 6 connected together by a transverse connecting rod 7.
  • One of the levers 6 is attacked by a connecting rod control 8 whose reciprocating movement in the direction of arrow F 1 is controlled by a dobby 9.
  • the weft threads are supposed to be moved, by a conventional mechanism, not shown, perpendicular to the warp threads, as shown by the arrow F 2 .
  • a beam 10 is arranged above the crowd, that is to say the zone of crossing of the warp threads 4 and the weft threads, parallel to the direction of the arrow F 2 .
  • this beam 10 are suspended two devices 20 and 20 ′, analogous and in accordance with the invention, the device 20 being more particularly visible in FIGS. 2 and 3.
  • the device 20 comprises a housing 21 slidably mounted on the beam 10 by means of four tie rods 22 whose heads 22 a are engaged in concave grooves 10 a and 10 b of the beam 10.
  • the device 20 can slide along the beam 10 in the direction of the arrow F 3 which is parallel to the arrow F 2 , while it is immobilized when these nuts 22 b are tightened.
  • the housing 21 supports an electric motor 23 which can be of any known type, but which is advantageously a servo motor.
  • a toothed pulley 25 around which is disposed a toothed belt 26 whose two ends 26 a and 26 b are respectively secured to the respective upper edges 27 a , and 28 a of two frames stringers 27 and 28. More specifically, the end 26 a of the belt 26 is fixed to the upper edge 27 a , of the frame 27 by means of four screws 29, while the end 26 b of the belt 26 is fixed to the upper edge of the frame 28 by four screws similar to the screws 29. Of course, other means of fixing the belt 26 to the frames 27 and 28 are conceivable.
  • the rotation of the motor 23 positively controls the frames 27 and 28 thanks to the cooperation of the complementary notches of the pulley 25 and of the belt 26.
  • a second belt 30, which may or may not be notched, connects the respective lower edges 27 b and 28 b of the frames 27 and 28 passing around a return pulley 31 disposed in the lower part of the housing 21.
  • a and 30 b the ends of the belt 30 secured to the edges 27 b and 28 b of the frames 27 and 28 by means of screws 29.
  • Elements 26, 27, 28 and 30 form a closed loop comprising two rigid parts, 27 and 28, and two parts flexible, 26 and 30.
  • the alternating rotation of the pulley 25 alternately drives the frames 27 and 28 in a substantially vertical direction, the movement of the frames being represented by the arrow F 4 .
  • Each heald frame 27 or 28 carries several healds 32 each provided with an eyelet 33 for passing the warp threads 4 'located on the left of Figure 1 and intended to form the edge.
  • the mounting of the beams 32 on the frames 27 and 28 can be adapted from known techniques for mounting beams 2 on the main frames 1 of the loom.
  • the ends 26 a, 26 b, 30 a and 30 b of the belts 26 and 30 are integral with the upper edges respectively 27a, and 28a, and lower 27 b and 28 b of the frames 27 and 28 in the central part of these edges , so that there is no overhang between the frames 27 and 28 and the flexible link formed by the belts 26 and 30.
  • Two return pulleys 34 and 35 allow the vertical strands of belts 26 and 30 in parallel planes relatively close, so that the heald frames 27 and 28 move in equally close parallel planes. This allows the device 20 to be very compact.
  • the pulley 31 is mounted in an oblong slot 36 of the case 21, which allows a tension adjustment of the belts 26 and 30 by displacement of the axis of the pulley 31 in the light 36.
  • Openings 37 and 38 provided in the sides of the housing 21 form two longitudinal slides in which the longitudinal edges 27 c , 28 c and 27 d , 28 d of the frames 27 and 28 are respectively engaged.
  • the housing 21 makes it possible to guide the frames 27 and 28 in their vertical reciprocating movement F 4 .
  • the device 20 has a modular, compact and rigid structure which can be installed quickly on a weaving loom with easy adjustment during time-delaying, by sliding along the beam 10 as shown by the arrow F 3 .
  • the device of the invention has the particular advantage that it can be installed on weaving looms already in service by the simple addition of a beam equivalent to the beam 10 and two mechanisms 20 and 20 '.
  • the actuator 23 is controlled regardless of the command generated by the loom or the dobby 9, so that a phase shift can be obtained in a particularly simple way between the bottom movement of the crowd of frames 1 and the crowd movement of the edges, at level of frames 27 and 28.
  • All training devices cams of conventional cam systems or the shafts of the FR-A-2 685 014 can be deleted, so that the assembly and disassembly of devices 20 and 20 'on the loom is significantly easier than in known systems.
  • the case 21 can include two slides on each side, each slide being adapted to receive and guide an edge longitudinal of a frame 27 or 28. This makes it possible to obtain a individualized guiding of the frames in translation.
  • a profession equipped with devices in accordance with the invention 20 and 20 ' is easier to control for an operator and more economical in investment and operating cost.
  • the invention has been shown with the beam 10 arranged above the crowd. It is however applicable with a beam arranged transversely in the lower part of the loom, that is to say below the crowd, and supporting devices analogous to devices 20 and 20 'above it.
  • the invention has been represented with a loom equipped with a dobby; however, it is applicable to Jacquard-type looms.
