Definitions

  • the invention relates to a thread clamp with a moveable lever for a gripper of a gripper weaving machine , to a gripper and to a gripper weaving machine.
  • grippers having thread clamps are known, wherein the thread clamps have a moveable lever pivotally mounted to a gripper body, which moveable lever is forced towards a counter-element, which counter-element is mounted to the gripper body or is part of the gripper body.
  • EP 0 207 533 A1 discloses a thread clamp with a moveable lever in the form of a needle having a circular cross-section and a counter-element in the form of a bit, which is provided with a groove, preferably with a V-shaped groove, at its upper surface arranged opposite to the needle.
  • EP 0 769 580 A2 shows another embodiment of a thread clamp for a drawing gripper having a holding member in the form of a needle, which is arranged opposite a groove-shaped semicircular cut-out.
  • a thread clamp for a gripper of a gripper weaving machine comprising a moveable lever having a first contact surface, and comprising a counter-element having a second contact surface arranged opposite to the first contact surface
  • the first contact surface for cooperating with the second contact surface
  • the first contact surface is provided with an inwardly arched portion, which inwardly arched portion is curved about an axis parallel to a longitudinal direction of the moveable lever and which inwardly arched portion extends longitudinally along said axis, wherein a curvature of the inwardly arched portion is in the form of a circular arc with a central angle and a radius, wherein the width of the inwardly arched portion is at least twice its height, and wherein the central angle of the circular arc is between about 40° and about 70°.
  • an arched portion extends longitudinally along an axis
  • the expression "an arched portion extends longitudinally along an axis" is used to describe that the arched portion has a longitudinal extension in the direction of said axis, wherein said axis is also referred to as longitudinal direction of the arched portion.
  • an arched portion having a width that is at least twice its height is also referred to as flat arched portion.
  • the moveable lever having a flat inwardly arched portion allows for a reliable clamping, wherein a weft thread can be clamped between the moveable lever and the counter-element with a clamping force having an at least essentially uniform force distribution along the width of a clamping zone of the thread clamp and with only a small deflection, so that a risk of damaging or breaking the weft thread is reduced.
  • a plane extending in the longitudinal direction of the inwardly arched portion and intersecting the inwardly arched portion through its apex is referred to as a middle plane of the arched portion.
  • the curvature of the inwardly arched portion is in the form of a circular arc. This allows amongst others for a simple and cost-efficient manufacture.
  • the curvature of the arched portion extends between opposing edge regions of the first contact surface.
  • the first contact surface is provided at its edge regions with two planar surface portions, wherein the inwardly arched portion is arranged between the two planar surface portions. Providing planar surfaces at the edge regions allows for a simple manufacturing while avoiding sharp edges.
  • a moveable lever having an arched portion and a planar surface portion can be combined with different counter-elements having a complementary arched portion at the second contact surface or having a planar second contact surface.
  • the first contact surface is provided at its edge regions with two planar surface portions, wherein the inwardly arched portion is arranged between the two planar surface portions, and wherein the first contact surface is further provided with two notches extending longitudinally along at least a part of the moveable lever, which notches are arranged at both sides and symmetrically with respect to the middle plane of the inwardly arched portion, and wherein each one of the two notches is arranged between the inwardly arched portion and one of the planar surface portions.
  • This moveable lever can be combined with several different counter-elements for a reliable clamping of weft threads.
  • an inner edge of each of the two notches is inwardly offset to an outer edge of said notch.
  • the inner edge and the outer edge extend the curvature of the arched portion.
  • the offset is chosen such that the arched portion, the inner edge and the outer edge are arranged on a common circular arc.
  • the second contact surface of the counter-element is planar.
  • the second contact surface is provided with an outwardly arched portion, which outwardly arched portion is complementary in shape to the inwardly arched portion of the moveable lever.
  • the counter-element is part of a gripper body. In other embodiments, the counter-element is a lamella.
  • the lamella can be mounted to the gripper body. In one embodiment, the lamella can be mounted to the gripper body so as to be replaceable for example upon wear or tear.
  • a gripper for a gripper weaving machine comprising a gripper body and a thread clamp is provided.
  • the moveable lever is at least partly resiliently deformable and forced due to its internal restoration force against the counter-element.
  • the moveable lever is pivotally mounted to the gripper body, wherein the moveable lever is forced towards the counter-element using at least one elastic element. This allows for a stiff moveable lever and high clamping forces.
  • the moveable lever is a two-sided lever, wherein one end is provided with the first contact surface, whereas the opposite end is co-operating with the elastic element for forcing the first end towards the counter-element.
  • the counter-element is part of the gripper body.
  • the counter-element is a lamella which is mounted to the gripper body, wherein in particular at least one elastic support element is provided on the gripper body, and at least a portion of the lamella opposite the second contact surface is supported on the gripper body via the at least one elastic support element.
  • the elastic support element influences a clamping force applied to the weft thread.

  • a gripper weaving machine comprising a gripper with a thread clamp according to one of the embodiments as described above.
  • the gripper with the weft thread clamp according to the invention is in particular used as a drawing gripper, also named bringer gripper, which is guiding a weft thread through a first half of a weaving shed.
  • a use of a lever having a first contact surface as a moveable lever in a thread clamp for a gripper of a gripper weaving machine comprising the moveable lever and a counter-element having a second contact surface, wherein the first contact surface is arranged opposite to the second contact surface, wherein the first contact surface is provided with an inwardly arched portion, which inwardly arched portion is curved about an axis parallel to a longitudinal direction of the moveable lever and which inwardly arched portion extends longitudinally along said axis, wherein a curvature of the inwardly arched portion is in the form of a circular arc with a central angle and a radius, wherein the width of the inwardly arched portion is at least twice its height, and wherein the central angle of the circular arc is between about 40° and about 70°.
