Abstract: The invention relates to a method for monitoring the bending of a shaft, particularly a shaft in a kneader, the shaft being supported on at least one side. In a first step, the deviation of the shaft from the radial position is measured at least one position differing from the bearing. In a further step, a comparative dimension is optionally determined from the measured deviation from the radial position. In a third step, the deviation from the radial position measured in the first step or the comparative dimension determined in the second step is compared with a prescribed threshold value.
