Abstract

The present invention relates to a method and apparatus for forming an absorption body by successively filling a mould having an air-permeable bottom with airborne cellulose-fibres or fibres of some other corresponding material, with the assistance of subpressure, and pressing the formed absorption body from the mould with the aid of overpressure. According to the invention, the subpressure beneath the mould bottom is varied in response to the variations in the resistance to air-flow exerted by the mould bottom and the cellulose-fluff which is collected successively in the mould. In the case of one preferred embodiment, a plurality of moulds are distributed circumferentially around a rotating wheel and a pressure chamber is assigned to each mould. The pressure chamber includes an opening (6) which coacts with an opening (14) in the side wall of a collecting chamber (10) connected to a subpressure source, therewith to form a connection between each pressure chamber and the collecting chamber.
