Abstract
A thread guiding wheel for use in textile machinery has a circumferential slot (8) adapted to receive a given yarn; the circumferential slot is generally V-shaped in section, having axially opposed walls (6, 7) which, in a radially inwards direction, converge to a base at which the walls intersect, the base of the V being sufficiently sharp to grip, between the axially opposed walls, a part of said yarn extending about at least a part of the circumference of the wheel.
