Vibrating apparatus for the production of mouldings by compaction

摘要

In the production of mouldings by compaction in vibrating apparatuses (10) which have above the mould box (21) a hood (11) provided with a vacuum connection to remove the gases liberated during compaction, it proves advantageous, in accordance with the invention, to connect the lower area of the mould box (21) to the hood (11) via a conduit (20). A vacuum balance is thereby advantageously achieved, preventing air from penetrating into the mould box from the outside at the bottom. <IMAGE>
