Definitions

  • the invention relates to a heddle for a weaving machine comprising a heddle eye part and one or more wire parts.
  • the invention relates to a weaving machine provided with one or more of such heddles.
  • the invention relates to a method for manufacturing a heddle for a weaving machine, comprising a heddle eye part and at least one wire part.
  • heddles When weaving, heddles are used which are provided for positioning warp yarns by means of an imposed motion during shed forming. To that effect, a heddle is provided with a heddle eye through which a warp yarn is extending.
  • the motion imposed on the heddle may be realized on the one hand by driving the heddle separately, for instance, by means of a Jacquard heddle, the extremity of which is connected to a harness cord and the other extremity of which is connected to a return spring, the harness cord being moved up and down through a number of positions by moving one or more hooks of a Jacquard machine, and the return spring, the other extremity of which is connected to the bottom or to the frame of the weaving machine, realizing the downward motion operating in conjunction with the motion of the hooks.
  • the motion imposed on the heddle may be realized by moving up and down several heddles simultaneously, for instance, several heddles each of which being connected to the same hook or to the same set of hooks of a Jacquard machine, or several heddles being incorporated in a heald frame, this heald frame being moved vertically by a driving or a selection device between two or several positions, in order to form a pattern desired in a fabric or in the texture of a fabric.
  • the last mentioned method is customary for driving warp yarns in flat fabrics, in backing fabrics of pile fabrics or for driving pile warp yarns in combination with a cam disc machine or a dobby device when a more limited designing is required.
  • warp yarns are involved per metre of weaving width in forming the shed, of which 4000 are pile warp yarns (8 colours x 500 reed teeth per metre) and 3000 backing warp yarns (3 backing warp yarns per fabric x 2 fabrics x 500 reed teeth per metre).
  • these warp yarns are changing their positions vertically by means of heddles which are driven (examples of driving methods are mentioned above).
  • lancets are used in the shed forming zone, either as spacers, or as supports for loop weft yarns.
  • these lancets take up their places in the weft direction in the space available for each warp yarn system. Consequently, the weft yarns and the heddles may also collide with these lancets during the shed forming.
  • the heddles have to meet the following requirements:
  • the heddles were made out of strip material.
  • the heddle was produced out of normally obtainable standard strip material, the material of which was removed above and below the heddle eye.
  • This is an expensive stage of the production, having the additional disadvantage that after the material has been removed above and below the heddle eye, quite some finishing is required to provide smooth transitional zones between the machined lateral surfaces, so that the warp yarns extending along these zones will not be obstructed in their movements or might be damaged.
  • heddles were chosen which were manufactured out of commercially obtainable strip material in which, in the centre, an opening was provided to serve as a heddle eye and where eyes were provided to hang up the heddle at the top and at the bottom.
  • no additional machining is required to realize smooth transitional zones, because these transitional zones will be realized during the manufacturing process of the commercially available material and will be maintained.
  • the width of the strip material required will still be considerable.
  • heddles are described with which the advantages of the use of wire outside the eyes of the heddle are combined with the advantages of strip material near the heddle eye.
  • a heddle eye is described which is made of strip material in which at the top and at the bottom recesses are provided into which, both at the top and at the bottom, wires are inserted which both are in line with one another and which, in that position, are welded or soldered to the heddle eye.
  • soldering or welding in this manner is difficult and expensive and may cause transitional zones which are not sufficiently smooth, will cause damage to the adjacent warp yarns or will collide with the lancets.
  • the purpose of the invention is to provide a heddle for a weaving machine comprising a heddle eye part and a wire part, wherein the heddle during weaving uses a large number of colours at a high density and at a high speed, yet realizing the vertical positioning of the warp yarn without impeding the motion of the warp yarn driven in the warp direction, obstructing the motion of the adjacent heddles and warp yarns as little as possible and interfering with the lancets as little as possible, and moreover, achieving a good resistance to wear with respect to the motion of the warp yarn moving through the heddle eye and with respect to any obstruction caused by the adjacent heddles, warp yarns and lancets.
  • the purpose of the invention is to provide a weaving machine with one or more heddles presenting the advantages mentioned above.
  • this purpose of the invention is achieved by providing a heddle for a weaving machine comprising a heddle eye part and a wire part wherein
  • one extremity of the heddle eye part is provided with a bore extending according to the longitudinal axis of the heddle and the wire part comprises a part which is reduced in the radial direction which is inserted into the said bore.
  • a heddle according to the invention is used, for instance, in a harnessless Jacquard machine and without return springs.
  • the two extremities of the heddle eye part are provided with a bore extending according to the longitudinal axis and two wire parts are provided, each comprising a part which is reduced in the radial direction which is inserted in a respective bore,
  • the external diameter of the heddle eye part at the extremities of the bores preferably substantially correspond with the diameter of the non-reduced parts of the wire part.
  • one or more of the said wire parts are at their other extremity provided with a part reduced in the radial direction, in order to enable the wire part to be inserted into a bore extending according to the longitudinal axis of the connecting element, the connecting element being provided to connect the heddle to the harness or the heald frame.
  • the one or more bores in the heddle eye part are provided with a cylindrical, oval, square, rectangular or any other geometrical form throughout the length of the axis of the bore.
  • one or more of the wire parts reduced in the radial direction, situated at the extremity of the wire part comprise at least one radial constriction near the place where, after the extremity of the wire part has been inserted into a bore extending in the longitudinal direction of the heddle eye part, the open extremity of the said bore is situated.
  • one or more of the bores of the heddle eye part have a section which is diminishing in the direction of the depth of the bores, and one or more of the parts reduced in the radial direction situated at the extremity of a wire part have a correspondingly reduced section.
  • the extremity of the heddle eye part around one or more of the open extremities of the bores are preferably thin-walled.
  • the heddle eye parts with the thin-walled extremities will be installed easily as the clearance between the wire part and the extremity of the heddle eye part around the bore becomes only small when both parts are pushed together.
  • a thin-walled extremity around a bore will enable to realize a plastic deformation of the heddle eye part around the extremity of the wire part, exerting only a limited force, in order to obtain the smooth transitional zone between the heddle eye part and the diameter of the wire part not having been reduced in the radial direction.
  • one or more of the bores in the heddle eye part are provided throughout part of their length with a lengthwise profiled surface and one or more of the parts reduced in the radial direction situated at the extremity of a wire part have a surface lengthwise profiled in the throughout part of their length which, after having been assembled, is situated near the profiled surface of the bore which is the counter profile of the said profiled surface of the bore.
  • one or more of the said bores in the heddle eye parts can be provided with thread throughout part of their length, and one or more of the parts reduced in the radial direction situated at the extremity of a wire part will have a correspondingly opposite thread profile in order to screw the part reduced in the radial direction into the bore.
  • one or more of the bores of the heddle eye part are having a lip at their open extremity, because of which the bore, in that particular place, has a diameter which is smaller than the diameter in the deeper lying part of the bore, and the wire part which is inserted into the said bore, at the extremity of the part reduced in the radial direction, has a radial constriction corresponding with the dimensions of the lip.
  • the lip will engage the radial constriction when the wire part will be completely installed in the bore.
  • the radial constriction is made sufficiently deep, the heddle eye part fits to the wire part under a certain pressure.
  • the said wire part into the said bore being provided with a lip
  • this wire part, at the free extremity of the part reduced in the radial direction preferably has a part provided with an increasing diameter, this increase being considered in a direction running from the free extremity of the reduced part towards the connected extremity of the reduced part which is connected to the rest of the wire part.
  • the closed extremity of the bore in the heddle eye part preferably has a correspondingly diminishing diameter, its diminishing considered in a direction from the open extremity towards the closed extremity of the bore.
  • the said lip at the open extremity of the bore, has a helical progression and the connected extremity of the part reduced in the radial direction has an opposite helical shape throughout its length, the helical shape considered in a direction from the free extremity of the part reduced in the radial direction towards the extremity of the reduced part which has been connected, being composed of:
  • the part reduced in the radial direction is carried out having a helical shape throughout the entire depth of the said bore. This gives the opportunity to make the connection between the heddle eye part and one or more wire parts to become detachable.
  • axial grooves In order to increase the elastic behaviour of the heddle eye part at the open extremity of the bore in the heddle eye part, preferably axial grooves have been applied.
  • the part reduced in the radial direction of one or more of the wire parts is consisting only of a radial constriction.
  • the purpose of the invention is attained by providing a weaving machine with one or more of such heddles.
  • a further purpose of the invention is to provide a method for manufacturing a heddle comprising a heddle eye part and a wire part, providing a heddle having the advantages mentioned above.
  • This further purpose of the invention is attained by providing a method for manufacturing a heddle for a weaving machine comprising a heddle eye part and at least one wire part, wherein the method comprises at least the following stages:
  • a heddle is manufactured as described above.
  • a heddle according to the invention comprises a heddle eye part and at least one wire part.
  • An embodiment of a heddle according to the invention has two such wire parts.
  • the heddle eye part at least at one extremity, is provided with a bore extending along the longitudinal axis of the heddle.
  • the heddle eye part is provided with two such bores.
  • the one or more bores in the heddle eye part may be of a cylindrical, oval, square, rectangular or any other shape throughout the length of the axis of the bore. Throughout the length of the bore, this shape may also pass from one geometrical form into another, for instance, from oval to cylindrical.
  • the wire part at least at one extremity, is provided with a part which is reduced in the radial direction which is provided to be inserted into a respective bore.
  • the transitional zone between the external circumference of the heddle eye part near the open extremity and the external circumference of the wire part with the diameter of the non-reduced part is progressing smoothly.
  • the heddle eye part is preferably, at one extremity, provided with a bore extending according to the longitudinal axis of the heddle and the wire part comprises a part reduced in the radial direction which is inserted into the said bore.
  • the two extremities of the heddle eye part may be provided with a bore extending according to the longitudinal axis of the heddles and be provided of two wire parts each comprising a part reduced in the radial direction, which is inserted into a respective bore.
  • the said smooth transitional zone between the heddle eye part and the wire part is realized by making the external diameter of the heddle eye part, at the extremities of the bores, substantially corresponding with the diameter of the non-reduced parts of the wire parts.
  • the external diameter of the wall around the extremity with the bore of the heddle eye part is substantially the same as the diameter of the non-reduced part of the wire part where it is changing into the part, reduced in the radial direction, of the wire part.
  • the method for manufacturing a heddle according to the invention comprises at least the following stages:
  • One or more of the said wire parts may be provided of a part, reduced in a radial sense, also at their other extremities, in order to allow the wire part to be inserted into a bore extending according to the longitudinal axis of a connecting element, the connecting element being provided to connect the heddle to the harness or to the weaving frame.
  • one or more of the parts reduced in the radial direction situated at the extremities of a wire part comprise at least one radial constriction near the place where, after the extremity of a wire part has been inserted into a bore extending in the longitudinal direction of the heddle eye part, the open extremity of the said bore is situated.
  • the part reduced in the radial direction of one or more of the wire parts is only existing of a radial constriction. Therefore, based on the wire profile commercially available, only a radial constriction will be applied near the place where, after insertion of the extremity of a wire part into a bore extending in the longitudinal direction, of the heddle eye part, the open extremity of the said bore is situated.
  • the technique for attaching the heddle eye part and the one or more wire parts consists in, for instance, deforming the extremity of the heddle eye part, so that it will engage the radial constriction because of which a smooth transitional is obtained between the external circumference of the heddle eye part and the external circumference of the one or more wire parts.
  • one or more of the bores the heddle eye part have a cross-section which is diminishing in the direction of the depth of the bores, and one or more of the parts situated at the extremity of a wire part which are reduced in the radial direction, have a corresponding diminishing cross-section.
  • the extremity of the heddle eye part around one or more of the open extremities of the bores is thin-walled.
  • the external diameter(s) of the extremity (extremities) of the heddle eye part are chosen such that, after having applied the manufacturing technique (for instance plastic deformation) when manufacturing the heddle, they will be adapted as closely as possible to the diameter of the non-reduced parts of the wire parts, so that, after having been connected a smooth transition zone will be realized.
  • a restricted thickness of the wall around the bore enabling plastic deformation to be used, as already mentioned above, likewise allows the diameter of the non-reduced parts (the starting material of the wire part), to be kept within certain limits, so that the space taken up by the wire part in the weaving machine may be kept limited,
  • one or more of the bores of the heddle eye part may have a surface which is profiled lengthwise throughout part of their length and, one or more of the parts reduced in a radial direction situated at the extremity of a wire part, after having been assembled, may have a surface which is profiled lengthwise throughout the part of their length, which after assembly, will be situated near this profiled surface of the bore, which is the counter profile of the said profiled surface of the bore.
  • the connection between the heddle eye part and the one or more wire parts may be realized, for instance, by pressing together or shrinking. This will increase the adhesion between the heddle eye part and the one or more wire parts.
  • the profiled surfaces may be toothed, provided with trapezium-shaped profiles or any other suitable profile.
  • one or more of the said bores of the heddle eye part may be provided with thread throughout part of their length or throughout their entire length and one or more of the parts situated at the extremity of a wire part and reduced in a radial direction, may have an opposite threaded profile, in order to screw the part, reduced in the radial direction, into the bore.
  • one or more of the bores of the heddle eye part may be provided with a lip at their open extremities due to which the bore in that particular place will have a diameter which is smaller than the diameter in the deeper lying part of the bore and the wire part which will be inserted into the said bore may have, at the extremity of its part which is reduced in the radial direction, a radial constriction corresponding to the dimensions of the lip.
  • the said wire part that has to be inserted into the said bore which is provided with a lip may have at the free extremity of the part reduced in the radial direction, a part with an increasing diameter the increase being considered in a direction from the free extremity of the reduced part towards the connected extremity of the reduced part which is connected to the rest of the wire part.
  • the closed extremity of the bore in the heddle eye part may have a corresponding diminishing diameter, its being diminished considered in a direction from the open extremity towards the closed extremity of the bore.
  • the said lip at the open extremity of the bore may have a helical progression
  • the connected extremity of the part reduced in the radial direction may have an opposite helical shape throughout its length, the helical shape being considered in the direction of the free extremity of the part reduced in the radial direction towards the connected extremity of the reduced part being composed of:
  • axial grooves may be applied in the heddle eye part at the open extremity of the bore.
  • heddle eye parts that are made of strip material are rather long.
  • the torsions above and below the heddle eye will be usually about 50 mm apart and between the torsion in the heddle eye part and the wire part about 15 mm should be estimated. Therefore, in the actual state-of-the-art, the total length of the heddle eye part, carried out with a double torsion and which means an enlargement with respect to the wire part, will usually be 80 mm.
  • a heddle eye part according to the invention may be shaped or tooled from any other material and freely designed, so that a good guiding of the warp yarn will be realized during its passage through the guide eye and the free design is simulating a torsion, due to which a favourable turning of the heddle eye is occurring as a result of a collision with a package of adjacent warp yarns, the distance between the centre of the heddle eye and the integrated torsion being limited to less than 10 mm for a heddle with a wire part of 0.9 mm due to which the total length of the heddle eye part may become shorter than 50 mm and preferably shorter than 30 mm.
  • materials preferably materials capable of being hardened are used, and as hardening techniques preferably such techniques are used enabling local hardening.
  • the hardness is important in and round the heddle eye and in the points of contact with surrounding warp yarns and lancets, whereas preferably the extremities of the heddle eye part around a bore will not be hardened.
  • plastics and fibre strengthened plastics may be used for heddle eye parts.
