Abstract
A fiber storing device includes an inlet for charging the device with fiber material and an outlet for withdrawing fiber material therefrom. The fiber storing device is associated with an apparatus for determining the fill level of fiber material in the storing device. The apparatus has an optical device which comprises a light emitter and a light detector and which is situated above an expected maximum fill level of the fiber material. The light emitter is arranged to direct, from above, a light beam onto an upper face of the fiber material and the light detector is arranged to receive a light beam reflected from the upper face of the fiber material.
