ABSTRACT:
A loom harness having nested pairs of cylinders. The pairs of cylinders are arranged in parallel fashion and offset in relation to one another on a rigid, stationary frame. Pillow blocks spaced along the frame support the cylinders. Flexible cables, connect the pairs of nested cylinders and support heddle eyes at their approximate midpoints. Alternatively, the cables can support heddle frames which, in turn, carry wire heddles. Control cables are attached to the upper and lower cylinders, and are moved upwardly or downwardly by a dobby. An alternative control includes an A-C servo motor and drive shafts to move the cylinders. The selective rotation of the various pairs of nested cylinders causes the translation of the heddle eyes. This movement of the heddle eyes causes a shed to be created in the warp yarn passing through the eyes.
