<p>An assembly (500) comprises a winding equipment (520) or twisting equipment (510) and a detector (530), The winding equipment (520) or twisting equipment (510) are adapted to wind or to twist a cord (110, 518) comprising magnetisable filaments. The detector (530) is installed on or is connected to the equipment (510, 520). The detector (530) comprises: a) a magnet (102) allowing passage of the cord (110), b) an detector (122, 124) for measuring variations (220, 330, 440) in magnetic flux caused by the passing cord (110), c) a sampler for sampling variations (220, 330, 440) in the magnetic flux, d) a module for transforming these variations (220, 330, 440) from the time domain into the frequency domain, e) a decision module for deciding whether or not to stop working of the equipment depending upon the result of the values (224, 334, 444) in the frequency domain.</p> |
