Definitions

  • the invention relates to a gripper clamp for a Bring gripper according to the preamble of claim 1 and a rapier weaving machine with a rapier clamp.
  • the first and second Has clamping member that is relative to a common axis are arranged pivotable to one another Pinch weft and which has a spring, which prestresses the clamping members against each other and the Clamping force generated.
  • the two clamping members form one Inlet gap and an adjacent clamping section within which the weft thread is clamped.
  • the invention has for its object the known Gripper clamps improve such that the disadvantages are fixed.
  • the gripper clamp contains a first and a second holding member 1 and 2, a hinge pin 3, a return spring 4 and a Stop element 5.
  • the first and second holding members 1, 2 are designed as two-armed levers and by means of Joint pin 3 connected to each other, the first Holding member 1 fixed and the second holding member 2 with respect the first is pivotally arranged.
  • the one Lever arm pair 11, 12 is on the opposite surfaces 13, 14 provided with tooth grooves 15 which in the Longitudinal extension of the lever arms 11, 12 are formed and interlock ( Figures 2 and 3).
  • This Lever arm pair 11, 12 forms starting from the free end an inlet section 16 with a decreasing gap width, a holding section 17 with a largely constant Gap width for the weft thread 18 and a section 19, in which the opposing surfaces of the lever arms 11, 12 lie one on top of the other, as shown in FIG is.
  • the lever arm 12 is the second Holding member 2 of the section 19 as a projection educated.
  • the return spring 4 is between the Lever arms 21, 22 of the other pair of lever arms arranged and holds the opposing faces of the section 19 of a pair of lever arms 11, 12 in resilient preloaded touch (Figure 2).
  • the stop element 5 is arranged in the return spring 4 and intended the executable by the other pair of lever arms 21, 22 Limit swivel movement and at the same time the Spring deflection 4.
  • A can be attached to the gripper clamp Organ 6 are attached to the depth of penetration of a Limit weft 18 in the hook clamp. Instead of the projection 19, a support part on a surface 13, 14 are applied.
  • Figure 5 shows an embodiment of the gripper clamp adjustable gap width.
  • To set the Minimum gap width in the holding section 17 is one Adjustment screw 31 and for setting the Maximum gap width an adjusting screw 32 is provided.
  • the adjusting screw 32 is connected to a steam organ 33, e.g. made of plastic.
  • the gripper clamp includes first and second Holding member 1, 2, which are arranged pivotably to each other and are in spring-loaded contact. Between the opposing surfaces of the holding links 1, 2 is a spacer 19 to one through the Grooves formed free space 15 for receiving a To create weft.
