Definitions

  • the present invention relates to small Jacquard machines specially established for the production of names, designs or other informative or decorative patterns on the edges of fabrics being woven.
  • a single mechanism 1 is used to ensure the simultaneous weaving of the two selvedges (or even in some cases of a third central selvedge).
  • This unique mechanism 1 is supported by the end of a structure 2 which surmounts the loom and it is driven by a lateral transmission 3 which connects its input shaft to a loom.
  • a structure 2 which surmounts the loom and it is driven by a lateral transmission 3 which connects its input shaft to a loom.
  • each of the actuating or hooks 1 of the mechanical organs 1 is associated with two (optionally three) harnesses 4 for controlling the heddle provided for weaving each edge .
  • harnesses 4 are necessarily arranged in the vertical axis of the edges of the fabric 5 in progress, so that their positioning must be capable of being modified depending on the width of this fabric and the exact location. of it on the craft. Given that for this adjustment, it cannot be envisaged to shorten or lengthen the ropes or arches of the harnesses 4, it is essential to provide additional return devices 6 whose displacement along the structure 2 makes it possible to adjust the vertical positioning of the harnesses without intervention on their length.
  • the present invention mainly intends to remedy, and this by assigning an independent Jacquard machine to each selvedge to be woven, capable of being adjusted in a horizontal position above the loom.
  • the Jacquard mechanism according to the invention is defined in claim 1.
  • the invention consists in making mechanics, directly equipped at its base with the drip board, an input shaft which is provided in tubular form so as to be crossed by a main drive shaft linked to the loom of the loom, at the same time as providing said mechanical means capable of allowing the adjustable fixing of its casing along a support beam which extends horizontally, parallel to the aforementioned main shaft.
  • the mechanics 7 illustrated in FIG. 2 comprises an input shaft 8 which receives its movement (alternating or continuous depending on the case) from the loom with which it is associated and which transforms it for the vertical control of the ropes or arches 9 of the corresponding harness.
  • this shaft 8 supported by bearings 10 attached in the side walls of the casing 7 a of the mechanics 7, is provided in tubular form and it is crossed axially by a main actuation shaft 11, oriented horizontally .
  • the shafts 8 and 11 are made angularly and axially integral with one another by means of a clamping flange 12 which acts on one end, provided slotted, of the tubular shaft 8.
  • the side walls of the casing 7 a of the mechanics 7 are notched so as to define two opposite horizontal faces capable of bearing on a beam or support 13, oriented horizontally below the shaft 11.
  • the immobilization of the casing 7 a on the beam 13 is operated using two lateral stirrups 14 associated with ears folded 7 b from the casing 7 a and with clamping nuts 15.
  • the beam 13 surmounted by the main actuation shaft 11 is supported by lateral columns 16, so as to be placed above the fabric 17 formed using the usual heald frames 18 controlled by a dobby classic.
  • two mechanics 7 according to the invention have been engaged on the shaft 11 and on the beam 13, and it is understood that by means of flanges 12 and nuts 15 , these two mechanics 7 are likely to be very easily brought to a position such that the heddles 19 of their harness are arranged at the edges of the edges to be produced.
  • each mechanism 7 is arranged in the manner of that described in the French Patent Application FR-A-2 677 380 filed in the name of the present Applicant on June 10, 1991.
  • the strings or arches 19 pass through perforations made in two tipping boards 20 and 21 rigidly fixed in superposition at the base of the casing 7 a , so that they are guided vertically to support the beams 19 and that the horizontal displacement of this casing ensures the corresponding displacement said healds, without any other adjustment maneuver than the sliding of the return springs 22 along the usual bar 23.
  • one of the ends of the shaft 11 is associated with a transmission 24 connected to a shaft 25 of the loom.
  • the two mechanics 7 are thus driven in synchronism to achieve the same weaving.
  • the beam 13 is capable of supporting any number of mechanics 7.
  • shafts 8 and 11 are capable of being provided with grooves, the first internally the second externally, in which case it is obviously possible to dispense with the flanges 12.
