ABSTRACT:
An apparatus for forming a fiber lap from fiber tufts includes a fiber opener having an input formed of a fiber feeding mechanism and a series of sawtooth rolls through which the fiber material introduced by the fiber feeding mechanism consecutively passes in a direction of advance; a pneumatic fiber stripping device including a blowing device for directing an airstream toward the last sawtooth roll of the series as viewed in the direction of fiber advance; a hood having an inner face defining a chamber situated above and downstream of the last sawtooth roll for receiving fiber material carried from the last sawtooth roll by the air stream of the fiber stripping device; an air-pervious, continuously moving receiving member disposed in the chamber downstream of the last sawtooth roll; and a suction device facing the underside of the receiving member for generating an air stream passing through the receiving member for drawing fiber material in the chamber onto the upper face of the receiving member for forming a fiber lap thereon.
