The position of foreign matter in a bale pattern after its separation in a separating device (10) may be evaluated in that the relative position of the opening device (1) and the transport time of the fibers between the opening device (1) and the separating device (10) is determined in each relative position. Given a separating procedure, taking account of the mentioned variables, the position of the opening device (1) at the point in time of opening the foreign matter (28) is evaluated. The determined opening position of the foreign matter on the fiber bales (27) is stored as a signal and subsequently preferably graphically represented. The method permits conclusions on the degree of contamination of the fiber bales.
