Abstract

A layer of compacted powdery microporous material is formed in a container of substantially air-impervious material by providing at least one air outlet region in the container together with barrier means which is adapted and arranged to substantially prevent passage therethrough of microporous material during compaction thereof, whilst permitting permeation of air displaced therefrom during such compaction. Also provided in the container is means to enable the displaced air permeating at least part of the barrier means during compaction of the microporous material to flow laterally of the direction of movement of a press tool between at least part of the barrier means and the base of the container toward the at least one air outlet region so as to be displaced from the container therethrough.
