Abstract (en)

[origin: EP0286950A1] The actual height of a fibre column (62) in a feed chute (40) is sensed, and a corresponding signal is compared with a desired level in an evaluation unit (56). A controller (58) reacts to any deviations, in order to control the supply of material by means of feed rollers and a feed-roller drive (34A). <IMAGE>
