Definitions

  • the invention relates to a method of eliminating the flock of harnesses with a positive recall of Jacquard looms, by air blowing, as well as a device for implementing the method.
  • Positive recall harnesses are commonly used in modern trades, and advantageously make it possible to increase the rate.
  • the flock from the wires accumulates in the lower part of the traction elements, hence fouling of these elements which causes ruptures, blockages, and which requires stops. repeated from manufacturing.
  • French patent 2475072 combines at the level of the heald return elements, on one side an air blowing according to a jet perpendicular to said elements, and on the other an air suction with the flock. This device, however, only partially solves the problem of fouling of the return elements, because it creates turbulent air flows in the vicinity of the return elastics and risks displacing the lifts.
  • a device substantially comprising a box, which encloses the return elements and a portion of the beams which pass without clearance one of the holes provided for this purpose in the upper face of the box, in which air circulation is ensured.
  • the latter device gives good results, but has the drawback of making the return elements difficult to access, and of prohibiting any variation in the spacing of the healds and therefore does not allow an increase in width in width of the loom. weave.
  • the establishment of air circulation requires air inlet and outlet pipes which increase the overall size of the assembly.
  • air is blown under pressure at the base of each traction element from bottom to top and substantially parallel to the axis of the return element.
  • EP-A 46 728 is to establish an air cushion outside the box and therefore is not free from any drawback.
  • One of the aims of the present invention is to provide a method and a device for eliminating the stuffing of harnesses, which overcomes the aforementioned drawbacks, which are reliable, which can be easily adapted on existing weaving looms, which allow maintenance easy of these weaving looms and which do not require significant means in terms of compressed air supply.
  • the method of eliminating the flock of harnesses with positive recall from mechanical weaving looms of the Jacquard type having traction elements recalling the healds downwards a process by which at the base of each traction element blows pressurized air from bottom to top and substantially parallel to the axis of the traction element, is characterized by the fact that the lower part of the traction elements is enclosed in a box comprising on the upper face of the openings in which the tension elements are passed with play and an overpressure of air is established in the interior volume of the box.
  • the invention also relates to a device for covering the method recalled above, comprising in particular means capable of causing at the base of each traction element a circulation of pressurized air directed from bottom to top parallel to the axis of the traction element, which is characterized by the fact that said means comprise a box enclosing the lower part of the traction elements, the upper surface of which has openings for the passage with clearance of each element, as well as means for put the case under air pressure.
  • reference (1) schematically shows beams, which are arranged relative to each other in a known manner.
  • the lower part of the heddles is connected to elastic return means (2), and for example helical tension springs, the lower end of which is provided with a hook (3) engaging on the bars of a box spring. or in one of the holes in a drip board (5).
  • any other suitable device is suitable, for example wrapped elastic bands.
  • the lower part of the elastic return elements (2) is enclosed in a box (6).
  • the box (6) is closed at its upper part by a plate (5a) provided with openings (4a) each traversed by the base of one of the return elements (2).
  • the openings have any suitable shape required, preferably circular but they allow the bases of the return elements to pass through with play.
  • the air Being able to escape only through the openings (4a), the air passes through the openings and then escapes substantially parallel to the axis of the return elements (2). As shown schematically by the arrows (9), the air thus flows along the elastic return means (2), and constitutes around these means a sort of fluid sheath which prevents the lashing of the flock to this level.
  • the air blowing means have a relatively low power.
  • the box (6) only encloses the base of the elastic return means (2), most of which therefore remains unobstructed, that is to say easily accessible for possible intervention. As for the heddles, they remain completely free and therefore, it is possible to increase the width in width by spreading them apart from each other at their eyelets, which only causes a slight inclination of their element. reminder.
  • its upper face (5a) can be formed directly by the grouting board (5), the holes of which then make the openings (4a).
