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.
Claims12
A warp beam comprising
- an elongated tube;
- a pair of flanges mounted on said tube to form lateral boundaries for a plurality of warp windings;
- and
- at least one tubular extension mounted onto and over one end of said tube.

A warp beam comprising
- an elongaated tube having a pair of ends;
- a first bearing member mounted on one end of said tube for mounting of the warp beam in a bearing of a weaving machine;
- at least one tubular extension mounted onto and over an opposite end of said tube;
- and
- a second bearing member secured to said tubular extension for mounting of the warp beam in a second bearing of a weaving machine.

In combination,
- a weaving machine having a warp beam end, a picking mechanism on one side for inserting a weft thread, a catching mechanism on an opposite side, and a pair of bearings at opposite sides of said warp beam end;
- and
- a warp beam mounted on said warp beam end of said machine, said warp beam including a tube having one end journalled in one of said bearings on said picking mechanism side of said machine and a tubular extension mounted on an opposite end of said tube and journalled in the other of said bearings on said catching mechanism side of said machine.
