Definitions

  • the invention relates to a heddle, comprising an inserted heddle eyelet which is provided with • a passage opening for a warp yarn, and
  • this carrier part consists of a part in which the inserted heddle eyelet is inserted and at least one part that extends beyond this inserted heddle eyelet, wherein the carrier part when the heddle with the inserted heddle eyelet in the attached state is viewed from the side, at least at one of the said edge lines and at least at the point of the transitions from the one or more parts of this carrier part that extend outside the inserted heddle eyelet towards the part of this carrier part in which the inserted heddle eyelet is inserted, is carried out such that it protrudes beyond the edge zone, and the outer circumference of the inserted heddle eyelet is at least partially visible.
  • heddles are used to position warp yarns during shed formation by imposing a movement on the heddle.
  • the heddle is provided with a heddle eyelet through which a warp yarn extends.
  • a heddle can be a jacquard heddle. Therewith, this is mostly connected at one end to a harness cord, and at the other end connected to a return spring, wherein the harness cord can take up a number of positions by the movement of one or more hooks of a jacquard device, and wherein a blade set takes along with it the hooks, and hence also the heddle and the harness cord, wherein in an upward movement, while return springs pull the hook, heddle and harness cord down again together with the downward movement of the blade, and wherein the return spring is connected at the other end to the base or frame of the weaving machine.
  • the movement imposed on the heddle can also be realised by moving a plurality of heddles up and down at the same time.
  • a plurality of heddles can each be connected by a respective harness cord to the same hook or to the same set of hooks of a jacquard device, or a plurality of heddles can be installed in a weaving frame, wherein the weaving frame is moved by a drive and selection device between 2 or more positions in height direction in order to form a desired pattern in a fabric or fabric structure.
  • This latter method is commonly used for controlling warp yarns in ground threads of pile fabrics or for controlling pile warp yarns in pile fabrics or of warp yarns in flat fabrics in combination with a cam disc machine or a dobby device when a limited patterning is required.
  • double-face pile weaving namely, all types of pile warp yarns that can be colour or pattern forming in the fabric are generally provided in each warp system, wherein the colour or pattern forming pile warp yarn extending between the upper and lower fabric and binding in each of these fabrics over a weft yarn, while the non-colour or pattern forming pile warp yarns are concealed as dead pile in the ground fabric of one of both fabrics.
  • lancets are deployed in many cases in the shed formation zone, either as spacers or as carriers of loop weft yarns. These lancets in turn take their place in weft direction in the available space per warp system. The warp yarns and heddles can thus also collide with these lancets during shed formation.
  • heddles were manufactured from wire material, wherein generally 2 wires were deployed next to one another and with a heddle eyelet being formed in the middle zone of the heddle. A warp yarn then extends through this heddle eyelet.
  • the 2 wires are connected to one another at a number of places outside the heddle eyelet.
  • This embodiment has the advantage that the heddle can be produced inexpensively, and that due to the limited dimensions of the wire material there is adequate free space for neighbouring warp yarns and lancets outside the heddle eyelet.
  • the formed heddle eyelet is distorted as a result of a collision with the neighbouring warp yarn package, the parts outside the heddle eyelet still allow sufficient passage for the neighbouring warp yarns and any lancet present.
  • This embodiment however has the disadvantage that the wire in the heddle eyelet is not particularly suitable for withstanding the wear caused by the warp yarn passing through it.
  • the thickness of the heddle eyelet is also limited to the thickness of the wire.
  • the joints of the 2 wires outside the heddle eyelet are not always resistant to the effect of the warp yarns and to the action of lancets moving along the heddle.
  • a wear-resistant inserted eyelet that is inserted into a space formed in the 2 wires and that is normally connected to these wires by means of a soldering process.
  • the resistance to wear of the heddle eyelet to the warp yarn has increased significantly.
  • the nearby warp yarns, the adjacent heddles and the neighbouring lancets collide with this connection and the inserted eyelet comes loose from the heddle.
  • strip material is generally commercially available steel with a limited thickness and with a width sufficient to allow the application of an opening as heddle eyelet.
  • material is taken away above and below the heddle eyelet in order to limit the weight and to create more space for the nearby yarns, heddles and any lancets present.
  • the removal of this material is an expensive production step that has the further disadvantage that after removal of the material above and below the heddle eyelet, a great deal of refinishing is necessary in order to give the machined sides smooth transitions so that the warp yarns moving along these sides are not hindered in their movement or are not damaged.
  • heddles are manufactured from commercially available strip material in which in the middle openings are provided as heddle eyelet. Therefore, no additional finishing is necessary to realise smooth transitions because these have been realised during the production process of the commercially available material and are retained.
  • the necessary width of the strip material is quite considerable, the eyelet thickness is limited, offering limited resistance to wear against the action of the yarn that moves through the heddle eyelet.
  • the width of the deployed strip material can be limited again -by carrying out additional machining at the opening made for the heddle eyelet in order to realise the heddle eyelet and to adapt the form of the heddle (by, for example, twisting the strip material) so that the movement of the neighbouring warp yarns and lancets from above the heddle eyelet to below the heddle eyelet or vice versa can take place more quickly.
  • Such solutions are described, inter alia, in US 5,348,055 and GB 448 723.
  • the twisting of the strip material has to take place at quite a large distance from the heddle eyelet in order not to distort the eyelet.
  • the heddle eyelet part is fairly large.
  • the one starting material involves a compromise with respect to the wear resistance in the eyelet part, and the whole heddle is quite large with a significant weight as a result.
  • the thickness of the heddle eyelet is smaller than the thickness of the wire.
  • the eyelet has to have a significant thickness so that, if the wire has to extend outside the heddle eyelet, the thickness of the wire has to be quite significant. This pushes up both the cost price and the weight of the heddle.
  • the thick wire also leads to the fact that the free space for positioning a package of heddles with the corresponding warp yarns and lancets is limited.
  • EP 1 908 863 then again presents a heddle that is manufactured from a fibre- reinforced polymer material as carrier wherein a heddle eyelet is inserted into a hard material and is glued to the reinforcing fibres with a synthetic resin.
  • a heddle eyelet is inserted into a hard material and is glued to the reinforcing fibres with a synthetic resin.
  • all the neighbouring heddles, warp yarns and lancets are passed along the heddle eyelet as much as possible.
  • the fibre package within the polymer material is distributed over 4 corners of the heddle eyelet in grooves in the heddle eyelet.
  • the object of the invention is consequently to provide a heddle that does not exhibit the said disadvantages of the prior art, that also offers sufficient resistance to the action of neighbouring warp yarns, heddles, and lancets, wherein the weight of the heddle remains limited and the volume taken up by the heddle parts outside the heddle eyelet, namely between the heddle eyelet and the connection of the heddle to the rest of the weaving loom, remains limited, wherein furthermore the heddle eyelet offers good resistance to wear against the action of the threaded warp yarn, and wherein operations are not necessary to connect the wire part at the inserted heddle eyelet with this inserted heddle eyelet.
  • This object of the invention is achieved by providing a heddle, comprising - an inserted heddle eyelet which is provided with
  • this carrier part consists of a part in which the heddle eyelet is inserted and at least one part that extends outside this inserted heddle eyelet, wherein the carrier part, at least at one of the said edge lines and at least at the point of the transitions from the one or more parts of this carrier part that extend outside the inserted heddle eyelet towards the part of this carrier part in which the inserted heddle eye is inserted, is carried out such that when the heddle with the inserted heddle eyelet in the attached state is viewed from the side, it protrudes beyond the edge zone, and the outer circumference of the inserted heddle eyelet is at least partially visibible and wherein the carrier part is provided such
  • the inserted heddle eyelet When a heddle is considered with an inserted heddle eyelet wherein the opening for the passage of warp yarn is viewed from the front (or in other words viewed towards the front surface of the inserted heddle eyelet), and wherein the longitudinal direction of the inserted heddle eyelet extends vertically, then the inserted heddle eyelet exhibits on the left and right (or on the left and right side of the inserted heddle eyelet) an "edge line", each being a line extending essentially vertically that follows the form of the inserted heddle eyelet at the front side of the inserted heddle eyelet and at the same time borders the outer circumference of the inserted heddle eyelet. In the same way the inserted heddle eyelet then also has such an "edge line" on its rear side on both the left and right.
  • the edge lines can be regarded as the parting line between the outer circumference and the front side or rear side of the inserted heddle eyelet respectively, so that these edge lines then belong to both this outer circumference and to this front side or rear side respectively.
  • edge zone a zone is meant that is located on the front and/or rear side of the inserted heddle eyelet, that has a limited width, and which follows an edge line mentioned above (see also figure 15 as described in more detail below).
  • the magnitude of this limited width has to be interpreted as, for example, the width of the inserted heddle eyelet on the front and/or rear side at the transition from the part of the carrier part that is in connection with the outer circumference of the inserted heddle eyelet (being the part of the carrier part in which the inserted heddle eyelet is inserted) and the carrier part that extends outside the inserted heddle eyelet when the inserted heddle eyelet is installed in the heddle.
  • the magnitude of this limited width can also be interpreted as the thickness of the carrier material. Consequently for a heddle according to the invention, at least one cross section can be defined perpendicular to the longitudinal direction of this heddle, wherein the carrier part protrudes beyond the edge zone of the heddle in the thickness direction of the heddle.
  • the inserted heddle eyelet can protrude in thickness direction of the inserted heddle eyelet towards the outside of the inserted heddle eyelet with respect to the carrier part with a part of its front side and/or rear side that is located between the edge zone and the opening for the passage of the warp yarn, as is the case in the second and seventh embodiment that are described in more detail below.
  • a heddle according to the invention has a longer lifespan compared with the heddles known from the prior art.
  • the positive effect on the lifespan is greater, the more the transition from the part of the carrier material that extends outside the inserted heddle eyelet towards the part of the carrier material in which the inserted heddle eyelet is inserted is smoother, and also the more the connection between the carrier part and the inserted heddle eyelet lies outside the area of the said neighbouring elements of the weaving machine.
  • the inserted heddle eyelet does not protrude at all with the respect to the carrier part, as shown for example in figures 2a to 2f that are described in more detail below, the inserted heddle eyelet extends completely in a cross section in width direction of the inserted heddle eyelet within the carrier part, both at the part in which the inserted heddle eyelet is inserted and of the part that extends outside the inserted heddle eyelet. In this way the contact of the inserted heddle eyelet with neighbouring elements of the weaving loom such as, amongst others, heddles, warp yarns and lancets is completely avoided.
  • a heddle according to the invention furthermore exhibits the following advantages with respect to the heddles known from the prior art: the use of an inserted heddle eyelet allows it to be manufactured from a wear- resistant material or from a material that can be made wear-resistant by an inexpensive treatment in order to offer good resistance to wear against the action of the warp yarn passing through it, a carrier part made of metal provides good resistance to wear of this carrier part. All metals with good resistance to wear can be used for this, such as stainless steel, hardened steel or coated metals.
  • the fact that the outer circumference of the inserted heddle eyelet is at least partially visible when the heddle according to the invention with the inserted heddle eyelet in attached state is viewed from the side indicates that the carrier material does not or practically does not extend over the whole width of the inserted heddle eyelet.
  • the carrier part protrudes over the full height of the inserted heddle eyelet at at least one of the said edge lines beyond the said edge zone when the heddle with the inserted heddle eyelet in the attached state is viewed from the side.
  • the carrier part protrudes at both said edge lines beyond the said edge zone when the heddle with the inserted heddle eyelet in the attached state is viewed from the side.
  • the inserted heddle eyelet can at one or more zones of the carrier part in which the inserted heddle eyelet is inserted at least partially be provided with at least one groove with a form corresponding to the form of the carrier part.
  • a connecting agent between the outer circumference of the inserted heddle eyelet and the carrier part at the transition from the part of the carrier part where the inserted heddle eyelet is inserted towards the part where the carrier part extends outside the inserted heddle eyelet.
  • This connecting agent can be glue, resin, solder, plastic or another known connecting agent.
  • the heddle according to the invention can have an inserted heddle eyelet with constant thickness. The advantage thereof is that the production of the inserted heddle eyelet is simplified.
  • the heddle according to the invention can also have an inserted heddle eyelet with a decreasing thickness from the middle zone of the inserted heddle eyelet where the passage opening for warp yarn is located towards at least a part of the edge zone of the inserted heddle eyelet.
  • the inserted heddle eyelet is carried out such that at the said middle zone it protrudes beyond the carrier part.
  • the inserted heddle eyelet has a thickness at the outer circumference thereof that increases from the lower and/or upper side of the inserted heddle eyelet towards the said middle zone.
  • the advantage of an increasing thickness towards the middle zone of the inserted heddle eyelet is that on the one hand the same thickness of the inserted heddle eyelet can be achieved at the passage opening (and hence the same resistance to wear attained) with a less wide (and hence less hindering) inserted heddle eyelet, while on the other hand if the increase in thickness is very gradual, the changes in direction of the carrier part can also be very gradual so that the impact of this change of direction on neighbouring heddles, warp yarns and lancets that come into contact with it during their movement is more limited.
  • the carrier part can first be constructed from 2 or more metal wires.
  • the carrier material can therewith consist of 2 metal wires that meet one another in two parts of the carrier part that extend outside the inserted heddle eyelet and in these parts are completely or partially connected to one another, are spread apart at the transition from a said part of the carrier part that extends outside the inserted heddle eyelet towards the part of the carrier part in which the inserted heddle eyelet is inserted, and extend in the following way at the place where the inserted heddle eyelet is inserted:
  • the first wire first extends downwards along the left-hand side or right- hand side of the inserted heddle eyelet, then extends around the lower side of the inserted heddle eyelet, then along the right-hand side or left- hand side respectively of the inserted heddle eyelet, then along the upper side of the inserted heddle eyelet, before finally extending downwards again along the left-hand side or right-hand side respectively of the inserted heddle eyelet, and
  • the second wire extends in the same way as the first wire around the inserted heddle eyelet.
  • the carrier part therewith consists of 2 metal wires that meet one another in two parts of the carrier part that extend outside the inserted heddle eyelet and in these parts are completely or partially connected to one another, are spread apart at the transition from a said part of the carrier part that extend outside the inserted heddle eyelet towards the part of the carrier part in which the inserted heddle eyelet is inserted, and extend in the following way around the outer circumference of the inserted heddle eyelet at the point at which the inserted heddle eyelet is inserted:
  • the first wire extends above the passage opening in the inserted heddle eyelet along the rear side of the inserted heddle eyelet, and extends below the said passage opening along the front side of the inserted heddle eyelet, and
  • the second wire extends above the said passage opening along the front side of the inserted heddle eyelet, and extends below the said passage opening along the rear side of the inserted heddle eyelet.
  • This embodiment has the advantage that with only 2 metal wires that do not each have to extend along the complete thickness of the inserted heddle eyelet, a heddle can be manufactured that is light and allows a limited material consumption even with inserted heddle eyelets with a greater thickness, and wherein the resistance to the effect of the neighbouring elements of the weaving loom, such as heddles, warp yarns and lancets, is significantly increased compared with the embodiments known from the prior art. Furthermore, when using two- wire material in the same thickness as for heddles according to the prior art, this embodiment allows an inserted heddle eyelet with a greater thickness to be used, thus increasing the resistance to wear from the passage of the warp yam.
  • the carrier part consists of 2 wires that meet one another in two parts of the carrier part that extend outside the inserted heddle eyelet and in these parts are completely or partially connected to one another, are spread apart at the transition from a said part of the carrier part that extend outside the inserted heddle eyelet towards the part of the carrier part in which the inserted heddle eyelet is inserted, and - extend in the following way around the outer circumference of the inserted heddle eyelet at the inserted heddle eyelet: the two ends of the first wire both extend - seen in the longitudinal direction of the heddle - along the same side above or below the inserted heddle eyelet outside the inserted heddle eyelet, while the two ends of the second wire both extend - seen in the longitudinal direction of the heddle - along the same opposite side above or below the inserted heddle eyelet outside this inserted heddle eyelet, wherein
  • the first wire first extends downwards along the front side of the inserted heddle eyelet, then extends around the lower side of the inserted heddle eyelet, before finally extending upwards again along the rear side of the inserted heddle eyelet, and

  • Such an embodiment of a heddle with 4 metal wires has a major advantage with relation to embodiments of a heddle according to the prior art that comprise an inserted heddle eyelet and 2 wires - wherein these wires are connected to one another completely or partly above the inserted heddle eyelet, spread apart at the inserted heddle eyelet and extend around this inserted heddle eyelet, and after the inserted heddle eyelet come together again and are connected to one another completely or partly, wherein each wire protrudes on opposite sides beyond the inserted heddle eyelet - that in this heddle according to the invention the wires have significantly less volume and weight, since when d is the diameter of the wires according to the prior art, the cross section of the carrier part above and below the inserted heddle eyelet of such an embodiment is 2 x p x d 2 /4 or thus p x d 2 /2, whereas in an embodiment of a heddle according to the invention with 4 wires these wires have a diameter of d
