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.
Claims14
A loom shaft comprising a heddle frame of upper and lower support bars, upper and lower heddle support rails attached to the support bars and heddles lined up on the heddle support rails, each heddle having two end eyes, at least one of the eyes being formed as an elongated opening extending in a longitudinal direction of the heddle in a manner that, even during operation and bending of the shaft in a region of a central area of the shaft, a distance between an inner rail edge of one of the support rails in the vicinity of said one eye and an outer rail edge of the other of the support rails is greater than a distance between an inner stop shoulder of said one end eye and an outer stop shoulder of the opposite eye, said loom shaft further comprising a strip of elastic material connected along said one of said support bars adjacent an inner edge thereof, said elastic material being engageable by an end portion of said heddle in which said end eye is formed to damp movement of said heddle during operation of said loom shaft.
