Abstract: The teaseling machine, comprising a rotor, arranged at regular intervals around the periphery of which are a plurality of revolving cylinders with teaseling clothing, has, in the space between adjacent teaseling cylinders, a deflecting cylinder that extends parallel to the axis of the rotor and to the axis of the cylinders and that can be adjusted radially relative to the rotor so that it produces an adjustable deflection of the span of fabric between one cylinder and the next, thereby varying the teaseling or brushing action of the cylinder clothings.
