Abstract
A ring spinning or twisting machine has rotating rings which are equipped with metallic flanges. Each ring has an associated permanent magnet device which can be moved to the vicinity of the flange so that the magnetic field interacts with it and generates eddy currents which tend to decelerate the rotating ring. The permanent magnets are mounted on a common sliding rod which is actuated by a servomotor. The displacement is such that each magnet moves substantially parallel to the plane of the flange and may occupy a position where the magnetic field is laterally adjacent to the flange and does not interact with it.
