  • Warp beam
    Patent number: 4318428
    Abstract: The warp beam is constructed with a hollow tube on which flanges can be symmetrically mounted as well as with a tubular extension at one end to permit asymmetric mounting in the bearings of a weaving machine. The warp beam is shaftless and the extension element has a slightly greater diameter than the diameter of the warp beam tube so as to render the warp beam more rigid. The rigidity of the warp beam reduces distortions and vibrations of the warp beam during weaving.
