Definitions

  • the invention relates to a training device for crowd for the realization of a selvedge and a loom equipped with such a device.
  • a loom makes it possible to fabricate a fabric on a width that can be important by forming a pattern or weave thanks to an appropriate device, especially a mechanical Jacquard or a dobby.
  • the lateral edges of the current fabric training courses are trained with the fabric and are likely to fray. It is known to use a cam system to control slats specific for side chain wires. he is also known, for example FR-A-2,685,014, to use a mechanical Jacquard specific for the realization of a selvedge on a fabric being woven.
  • Jacquard mechanism is relatively complex and requires its mechanical connection to a main drive shaft, which involves mounting a such shaft remote from a motor shaft of the trade.
  • a Jacquard mechanics is a relatively elaborate system that is not necessarily adapted to the simplest cases in which a margin with a substantially uniform pattern must be created.
  • EP-A-0 750 061 proposes a device for carrying out a false border with no gauze that does not allow weaving a true edge because it includes only two smooth associated with a smooth panties, these rails being mounted in cantilevered on a belt and mechanically stressed in permanently. Relatively massive rails should be used, their inertia and rigidity not being compatible with the weaving of a selvedge.
  • the aim of the invention is to propose a training device for the crowd for a real edge of simple construction, so reliable, and that does not need to be connected to a motor shaft of the craft.
  • the invention relates to a device for crowd formation for the realization of a selvedge on a Fabric being manufactured on a loom, characterized in that it includes two frames each carrying several smooth and with longitudinal edges and upper edges and lower. These frames are moved, according to a movement alternatively substantially vertical in opposition of phases, by at least one flexible link actuated by an electric motor and connected to their upper or lower edges.
  • the two smooth frames allow to control the movement of the warp threads of a loom weave in a simple armor movement suited to selvedges and thanks to the electric motor that has to be connected to a control power unit by an electrical connection significantly simpler to install than a drive shaft.
  • the use of heald frames makes it possible to control parallel of the rails in sufficient number for a weaving corresponding to the width of a usual border, the frames to obtain a precise positioning of the smooth, then that they effectively resist the efforts flexible link.
  • This link flexible may be a belt, a chain or the like.
  • the electric motor can be easily controlled, so that the movement of the heald frames is out of sync with to that of the main device for training the crowd of craft, be it dobby frames or a harness Jacquard.
  • the invention finally relates to a loom equipped with a least one device as previously described.
  • a loom includes a device such as previously described at each edge of the fabric in manufacturing course.
  • the loom shown in FIG. several heald frames 1 arranged parallel to each other others and carrying smooth 2 whose eyelets 3 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 interconnected by a transverse link 7.
  • One of the levers 6 is driven by a connecting rod.
  • control 8 whose reciprocating movement in the direction of the arrow F 1 is controlled by a dobby 9.
  • the weft son are supposed to be moved, by a conventional mechanism, not shown, perpendicular to the warp son, as represented by the arrow F 2 .
  • a beam 10 is disposed above the crowd, that is to say, the crossing zone of the warp son 4 and the weft son, parallel to the direction of the arrow F 2 .
  • this beam 10 are suspended two devices 20 and 20 ', similar and in accordance with the invention, the device 20 being more particularly visible in Figures 2 and 3.
  • the device 20 comprises a housing 21 slidably mounted on the beam 10 by four tie rods 22, the heads 22a are engaged in the 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 22b are tightened.
  • the housing 21 supports an electric motor 23 which can be of any known type, but which is advantageously a servomotor.
  • a toothed pulley 25 around which is arranged a toothed belt 26, the two ends 26 a and 26 b are respectively fixed to the respective upper edges 27 a and 28 has two frames smooth 27 and 28.
  • the end 26a of the belt 26 is fixed on the upper edge 27 a of the frame 27 by four screws 29, while the end 26 b of the belt 26 is fixed to the upper edge the frame 28 by four screws similar to the screws 29.
  • 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 the belt 26.
  • a second belt 30, which may be toothed or not, 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. respectively denote 30a and 30b the ends of the belt 30 integral with the edges 27b and 28b of the frames 27 and 28 by means of screws 29.
  • the 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 a plurality of healds 32 each provided with an eyelet 33 for the passage of the warp threads 4 'located on the left of Figure 1 and intended to form the edge.
  • the mounting of the rails 32 on the frames 27 and 28 can be adapted from known techniques for the assembly of the rails 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 secured to 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 the edges of so that there is no overhang between the frames 27 and 28 and the flexible link formed by the belts 26 and 30.
  • Two pulleys 34 and 35 make it possible to arrange the Vertical strands of belts 26 and 30 in parallel planes relatively close, so that the frames of smooth 27 and 28 move in parallel planes also close. This makes it possible to obtain a great compactness of the device 20.
  • the pulley 31 is mounted in an oblong slot 36 of housing 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 guides in which are respectively engaged the longitudinal edges 27 c, 28 c and 27 d, 28 d frames 27 and 28.
  • the housing 21 helps guide frames 27 and 28 in their vertical reciprocating movement F 4 .
  • the device 20 has a modular structure, compact and rigid that can be installed quickly on a loom with easy adjustment during the delay, 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 looms already in service by the simple addition of a beam equivalent to the beam 10 and two mechanisms 20 and 20 '.
  • control of the servomotor 23 is carried out regardless of the order generated by the loom or the dobby 9, so that a phase shift can be obtained particularly simple way between the background movement of the crowd of executives 1 and the crowd movement of the selvedges, at the level of frames 27 and 28.
  • All training devices cams of conventional cam systems or shafts of system FR-A-2 685 014 can be deleted, so that the assembly and disassembly of devices 20 and 20 'on the trade is significantly easier than in known systems.
  • the housing 21 may include two slides on each side, each slide being adapted to receive and guide an edge longitudinal axis of a frame 27 or 28. This makes it possible to obtain a individualized guidance of the frames in translation.
  • a loom equipped with devices according to the invention and 20 ' is easier to control for an operator and more economic investment and cost of operation.
  • the invention has been shown with the beam 10 arranged above the crowd. However, it is applicable with a beam arranged transversely in the lower part of the loom, that is to say below the crowd, and supporting devices similar to devices 20 and 20 'above it.
  • the invention has been shown with a loom equipped with a dobby; however, it is applicable to Jacquard type crafts.
