Abstract: An apparatus for detecting foreign bodies in fiber material includes at least two light sources. At least one of the light sources has at least three light emitting elements. Each light emitting element radiates a light of different color. An arrangement directs the light emitted by the light sources to the fiber material for illuminating the fiber material, and a sensor detects the illuminating light after illumination of the fiber material for emitting an electric signal upon a sudden color change of the fiber material. An arrangement causes the light sources to alternatingly illuminate the fiber material with different colors, and further, an arrangement selects the color emitted by the light sources as a function of the color of the fiber material.
