Abstract

A magnetisable false twist bush which is driven by contact of its outer surface with a drive element with which it is held in contact by magnets arranged on each side of the drive element, is formed by pref. drilling a central base through a circular cross-section rod whilst it is held in a chuck, and then machining, pref. with a grinding wheel, the outer surface of the rod smooth in a single operation with pref. the rod supported on a mandrel and held in a chuck at one end. Subsequently a transverse pin (for blocking twist) is located in the mouth at one end of the bore. The outer diameter of the bush is machined completely accurately along its length and no projections (e.g. flanges for co-operation with the drive elements) are provided on the outer surface. Vibrations of the bush due to gyroscopic effect are prevented allowing the bush to be rotated at speeds of 500000 rpm.
