Abstract
A device for obtaining a control signal corresponding to the density of the fibre covering lying on a fibre carrying element such as the cylinder, the licker-in, the take-off roller, or the doffer of a card. The device includes a holder which extends over the width of the fibre carrying element to span the width of the fibre covering on the fibre carrying element. This holder contains means responsive to the density of the fibre covering which produces electric output signals corresponding to the density of the fibre covering.
