Abstract
A feed apparatus for a fibre layer on an opening roll of cards or spinning preparatory machines fed with the fibre layer, wherein a feeder plate together with a feed roll forms a clearance or gap extending from the entrance or mouth of the feeder plate. Immediately upstream of the feeder plate a presser member is arranged to be movable towards the feed roll into a position in which the fibre layer is compressed and at least to a distance essentially corresponding to the width of the clearance or gap at the entrance or mouth of the feeder plate.
