Abstract
A nozzle mechanism for generating a twist in a yarn in an air-jet spinning machine, the nozzle comprising a central cylindrical duct having an axis through which a yarn is delivered in a selected direction and a bore having an axis and a diameter entering tangentially into the cylindrical duct for inputting compressed air into the duct, the bore entering the duct such that the axis of the bore forms an obtuse angle with the axis of the duct, the bore further entering the duct such that the perpendicular distance between the axis of the bore and the point of tangential entry of the bore into the duct is less than half the diameter of the bore.
