Abstract
A fiber preparation machine for processing fiber material includes a store or filling chute for storing the fiber material before or after processing. A camera is directed into an interior of the store or filling chute, the camera having an optical axis oriented at an angle (α) with respect to a vertical axis that is perpendicular to a surface of the fiber material in a range of plus 30 degrees to minus 30 degrees. The camera has a resolution for detecting a particle having an extension of 0.1 mm2 on the surface of the fiber material.
