Definitions

  • the present invention relates to a heald for a heald of a loom.
  • Such heddle shafts are equipped with a large number of strands, each strand has a thread eye through which a warp thread is guided in each case in the position of use of the strand.
  • the healds are moved up and down during operation of the loom to form a shed into which the weft is entered.
  • the healds move up and down at high frequencies, which places high demands on the healds. Even with strong accelerations or delays of the heddles and the warp threads guided therein damage to the warp, as well as excessive wear of the heddle should be avoided.
  • the design of the thread eye is therefore of great importance in order to avoid the mentioned problems.
  • the EP 1 795 635 A1 describes a heddle for tape-shaped warp threads.
  • the thread eye of this strand is introduced substantially as a slot-shaped opening in a flat, ribbon-shaped strand body.
  • the thread eye is provided in the region of the thread support surfaces with a radius. This radius can be achieved by attaching separate cylindrical or partially cylindrical elements whose radiused edge is attached to the top or bottom of the thread eye.
  • adjacent to the top and the bottom of the thread eye introduced tongues from the plane of the flat Strand body bent out, whereby at the edge of the thread eye, a bending radius is formed, which serves as a thread support surface for the ribbon-shaped strand.
  • a heald which has a strand body made of a wire. Between two parallel wires of the strand body a Maillon is used, which forms the thread eye. The Maillon is provided to the thread eye with a radius.
  • US 6 145 549 also discloses a heddle for tape-like warp threads, which has a rectangular in cross-section strand body.
  • the thread eye is designed in the form of a parallelogram, wherein the two edges forming the thread support surfaces extend obliquely to the horizontal and to the vertical.
  • the thread eye is rounded on the Kettfadeneintrittsseite and Kettfadenaustrittsseite, wherein the thread support surface extends therebetween.
  • the thread support surfaces can be configured flat or channel-shaped. Furthermore, the thread eye can widen into a funnel-like manner towards the warp thread entry side or to the warp thread exit side.
  • this funnel-like extension is shown schematically in the form of a curvature. The course of the funnel-like extension is not described in detail.
  • the disadvantage here is that the warp thread in the embodiment of the thread support surface in the form of a groove is only then guided laterally sufficient when it has contact with the thread support surface.
  • the warp thread lifts off the thread support surface, its lateral guidance is only through the two ensures in the longitudinal direction of the heddle body extending narrow guide webs, which are offset in the warp direction to each other.
  • the hedge can twist around its longitudinal axis.
  • the two thread support surfaces which are arranged opposite one another in the longitudinal direction of the heddle body, each have a first curvature region and a second curvature region whose curvatures are different.
  • the curvature of the first and the second curvature region is constant in each case, the amounts of the curvatures of the two curvature regions being different.
  • the curvature in the first curvature region is greater in magnitude than the curvature in the second curvature region.
  • the first curvature region may be associated with the warp thread entry side of the thread eye and the second curvature region with the warp thread exit side of the thread eye.
  • the warp thread support surface has two curvature regions with different curvatures.
  • the warp thread extends along the entire contact surface always curved on the thread support surface, so that a local overstressing of the warp, for example, at an edge of the thread eye, is avoided. If required, for example in the case of thicker plastic strands, the thread support surface can also have several areas of curvature.
  • An independent further aspect of the invention for improved reception of the warp thread is to improve the lateral guidance of the warp thread in the region of the thread eye.
  • the thread eye is transversely to the longitudinal direction of the heddle body and transverse to the warp direction, in which the warp thread the thread eye from the Kettfadeneintrittseite passes through the warp thread exit side, bounded by a respective guide web.
  • the distance between these two guide webs in the transverse direction is substantially adapted to the thickness of the warp thread and therefore often so small that it would not provide sufficient space for a Einziehnadel for drawing the warp thread.
  • the guide webs therefore each have a central portion, wherein the leading edge of the warp thread entry side is spaced from the warp thread entry side of the thread eye and the trailing edge of the other guide web associated with the warp thread entry side, the trailing edge also being spaced from the warp thread exit side of the thread eye.
  • the trailing edge of the entry-side guide web Seen in the direction from the warp thread entry side to the warp thread exit side, the trailing edge of the entry-side guide web is arranged in front of the front edge of the exit-side guide web. In this way, a pull-in opening between the front edge of the one guide web and the trailing edge of the other guide web is provided transversely to the warp direction in the transverse direction.
  • each guide web adjacent to the central portion on both sides in each case an end portion which connects the central portion with the respectively associated thread support surface of the thread eye.
  • the end portions of the guide webs extend in the warp direction along the entire thread support surface, to which they adjoin.
  • the end sections are, as it were, guide lugs for the warp thread, which rise next to the thread support surfaces. In this way, a lateral Kettfaden arrangement is ensured even if the warp, for example, due to high accelerations or delays of the hive briefly lifts off the thread support surface.
  • the extended in the end sections guide rails also prevent torsion of the heald around its longitudinal axis.
  • this embodiment of the thread eye according to the invention ensures improved lateral guidance of the warp thread. At the same time is still created a sufficiently large intake opening in the transverse direction.
  • the thread support surfaces are curved in the two curvature areas exclusively in the warp direction.
  • the thread support surface is preferably flat in the transverse direction between the two guide webs. In this way, it is avoided that the warp thread jammed in a direction of curvature in the transverse direction tread support surface. The lateral guidance takes place exclusively through the two guide webs.
  • the length of the curvature region with the smaller curvature may be larger and preferably at least twice as large as the length of the curvature region with the magnitude greater curvature.
  • the length is measured along the surface of the respective curvature region between the warp thread entry side and the warp thread exit side. In this case, the point of the smallest distance between the two opposite thread support surfaces in the curvature region with the smaller magnitude curvature lie.
  • the two thread support surfaces are curved from the Kettfadeneintrittsseite to Kettfadenaustrittsseite along its entire extent. It may be sufficient, only two curvature areas with different To provide curvatures.
  • the first curvature region adjoins the warp thread entry side, merges at a transition point into the second curvature region, which extends to the warp thread exit side. It is expedient if a tangent applied to the thread support surface at the transition point extends both tangentially to the curvature of the first curvature region, and tangentially to the curvature of the second curvature region following the transition point.
  • the transition between the two curvature areas is edge and infinitely designed.
  • the curvature of the first curvature region is advantageously adapted to the warp thread entry angle and the curvature of the second curvature region to the warp thread exit angle. This can be done, for example, such that a contact point is determined for both curvature regions, at which the warp thread in the open shed position, i. maximum excavation, the heald should come into contact with the thread support surface.
  • the radius or the curvature of each curvature region can be determined so that the warp thread at the contact points in each case runs tangentially to the thread support surface.
  • the lateral guide webs are preferably formed such that their thickness in the central portion and in the two end portions is substantially constant. As a result, both on the outside of the heddle body, and on the inside of the guide webs facing the thread eye, a flat surface can be achieved, along which the warp thread can slide.
  • the height of the end sections measured perpendicular to each adjacent thread support surface is greater than the diameter of the warp thread.
  • the height of the end portion measured perpendicular to the thread support surface may increase in the warp direction towards the central portion of the guide web.
  • the narrow side of the end portion may extend obliquely to the longitudinal direction of the heddle body. This oblique course can be rectilinear and / or curved and / or curved. If the warp thread guided through the thread eye reaches the narrow side of an end section, then it can slide along there and is finally guided to the thread support surface. Likewise, a warp thread passed between a pair of strands through a heald does not hang on an end portion, but slides along the sloped narrow side and finally disengages from the heald.
  • the thread eye is preferably formed or limited directly by the heddle body.
  • the heald is designed without inserts on the thread eye.
  • the heddle is preferably made entirely of plastic and thus forms a plastic strand. This can be produced for example by casting, injection molding or transfer molding. The entire plastic strand is therefore manufactured as one piece. A connection of several items in the manufacturing process is avoided. Plastic strands are characterized by their low mass and corrosion resistance. Therefore, they are preferred in Water jet looms are used, which can reach very high operating speeds.
