ABSTRACT:
A loom shaft for a heddle has two end eyes in which at least one eye is elongated in the longitudinal direction of the heddle such that even during operation and bending of the shaft in the region of the shaft center, the distance between an inner rail edge of the heddle support rail and the region of the cutout end of the eye and the outer rail edge of the opposite heddle support rail is greater than the distance between the inner stop of the cutout end eye and the outer stop of the opposite end eye. The inner edge facing the heddle support rail may be of elastic material on at least one support bar of the shaft to prevent impact of heddles against the support bar during high stress placed on the shafts.
