Definitions

  • the invention relates to a weaving sheave suitable for weaving machines, especially suitable for fast-running weaving machines is.
  • heald shanks for shedding.
  • the heald frames are replaced by a front view formed essentially rectangular frame whose upper and lower long longitudinal edge each by a shaft rod is formed. Laterally, the shaft rods are by side supports connected.
  • the shaft rods are often by hollow chamber profiles educated.
  • On the shaft rods are Litzentragschienen attached, which carry the healds. Every heald has at least one thread eye through which a Warp thread is guided. To shed the shafts moving up and down in quick succession. For large fabric widths arise very long shaft rods, depending on from the weaving speed (number of turns) to the deflection tend.
  • Such center connectors are struts that connect the two shaft rods with their ends.
  • a weaving shank with such a middle connector known.
  • the Shaft rod consists of sheet metal profiles, between which one Filler core, e.g. made of plastic foam, honeycomb Material or a light wood species is arranged.
  • the Filling material is glued to the sheet metal profiles.
  • a way to insert the center connector to create is one existing between the sheet metal profiles Free space filled by a rubber body, with the flat Sheet profiles firmly adhered, e.g. sticky is.
  • the rubber body is an extension of a rail holding one with a widened head as well inserted into the space between the two sheet metal profiles so-called sliding element holds.
  • this Screws are used here as an intermediate strut Hold designated center connector.
  • the weave is formed here by a hollow chamber profile, which in the area the middle connector a the other shaft rod may have facing window.
  • a holding body is arranged, the is connected to the side walls of the hollow chamber profile.
  • DE 32 20 710 C2 discloses a heddle shaft with shaft rods known at their respective Litzentragschiene facing side a narrow chamber for receiving a Have clamping piece.
  • the chamber is to the Litzentragschiene accessible through a window.
  • One in the chamber inserted clamping piece offers here an abutment for the Center connector.
  • the power transmission between the middle connector and the shaft rod is relatively small-scale. Also required the formation of a longitudinally continuous chamber for the clamping piece an increased cost of materials and thus leads to a considerable mass of the shaft rod.
  • each shaft rod is based on DBP 1083759.
  • each shaft rod For attaching several Center connectors are each shaft rod at its the shaft stave facing side provided with an opening, by a corresponding arranged in the interior Holding piece is accessible. This has tapped holes for receiving screws on which the middle connector hold.
  • the heddle according to the invention has a shaft rod on, which is designed as a hollow profile body and the at least one, but preferably two or more closed Hollow chambers .aufêt, which extends longitudinally through the Extending shaft rod therethrough.
  • the hollow chambers point in the process preferably a longitudinally invariable cross-section on.

  • the invention makes it possible, wide heddles with long Provide shaft rods, these shafts suitable for high web speeds. It is not a separate one Chamber for clamping pieces or the like for attachment of middle connectors required. It can therefore very lightweight shaft rods are used, the not for the construction of heddles with middle connectors are provided. It can thus the corresponding hollow chamber profile body be cut to length from an endless profile, usually made of shorter shaft rods become.
  • the intended for receiving the retaining piece hollow chamber is preferably a hollow chamber, which at the ends of Shank bar accommodates corner connector pieces.
