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 2,475,072 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 stuffed.
  • This device 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 elements of return and part of the beams which cross without play 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.
  • One of the aims of the present invention is to propose a method and a device for eliminating the stuffing of harnesses, which overcomes these drawbacks, which are reliable, which can be easily adapted on existing weaving looms, which allow maintenance easy of these looms and which do not require significant means in terms of compressed air supply.
  • the method according to the invention is characterized in that at the base of each traction element, from bottom to top and substantially parallel to the axis of the return element, air is blown under pressure.
  • the invention also relates to a device which is characterized in that it comprises means capable of causing at the base of each traction element a circulation of high pressure air directed from bottom to top parallel to the axis of the reminder.
  • 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 grouting 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, 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 by the arrows (9), the air thus flows along the elastic return means (2), and forms around these means a kind of fluid sheath which prevents the lashing of the wad at 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 moving 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) whose holes (4) then make the openings (4a).
