Abstract
A heddle shaft is formed of shaft rods which have hollow ends containing inserts fixedly positioned therein and lateral supports which include projections that respectively extend into recesses in the inserts. Clamping screws, which can extend through the shaft rods, apply a compressive force to clamp the projections in place and create detachable corner connections between the shaft rods and the lateral supports.
Claims12
Heddle shaft comprising lateral supports and shaft rods and having a detachable corner connection between at least one of the lateral supports and at least one of the shaft rods, the shaft rods consisting of hollow sections and into whose hollow space, at each corner connection, a projection extending transversely from the lateral support fits plug-like and is clamped by at least one detachable clamping means, wherein non-elastic insert that has first and second legs defining a generally U-shaped or pincer-shaped receptacle open toward the lateral support and intended to receive the plug-like projection is located in the hollow apace and is fixedly connected to the respective shaft rod, and said clamping means includes at least one screw which threadingly extends through a threaded hole in said first leg of said insert to apply a force toward the plug-like projection and in a direction substantially parallel to the lateral support in order to hold in a clamping manner the projection in the receptacle.
Heddle shaft comprising lateral supports and shaft rods and having a detachable corner connection between at least one of the lateral supports and at least one of the shaft rods, the shaft rods consisting of hollow sections and into whose hollow space, at each corner connection, a projection extending transversely from the lateral support fits plug-like, wherein a non-elastic insert that has a receptacle open toward the lateral support and intended to receive the plug-like projection is located in the hollow space, securing means for fixing each insert in said hollow space of each respective shaft rod comprising rivets, a weld joint or gluing, and including at least one clamping means to create a gripping and/or clamping force directed toward the plug-like projection in a direction substantially parallel to the lateral support in order to hold in a clamping manner the projection in the receptacle.
A heddle shaft which includes the shaft rod defining a hollow interior at one end thereof and an elongated lateral support which includes a side projection that is removably positionable in said hollow interior;
- a one-piece insert element located in said hollow interior of said shaft rod, said insert element providing a channel into which said projection can extend;
- securing means for fixedly positioning said insert element in said shaft rod;
- and clamping means for clamping said projection within said channel of said insert element and connecting said lateral support to said shaft rod, said clamping means applying a force towards said projection in a direction generally parallel with said elongated lateral support.
