Abstract:
A method for inspecting cigarette heads (25, 41, 61), where light radiates in at least two strip-like portions (26-31), which are incident from different directions, onto the end area (39, 42) of a cigarette head (25, 41, 61) and light (33) reflected from the end area (39, 42) is received by a detector (32) and evaluated, wherein, in the course of evaluation, a distance (B, C) between two lines (54, 55, 68, 69) which are produced from a signal generated by the detector (32) and correspond to the strip-shaped portions (26-31) is determined in order to establish the position of that region of the cigarette head (25, 41, 61) which is irradiated by the portions (26-31).
