ABSTRACT:
An apparatus is provided for moulding a polymeric foam into a bun in a longitudinally-extending, channel shaped mould by a mobile vessel and fall plate which are progressively transported from one end to the other of the mould to lay down partially-expanded foam over the bottom of the mould. The apparatus includes a mould for receiving a polymeric foam and including a longitudinally-extending, channel-shaped enclosed mould through which a mobile vessel and fall plate are progressively transported from one end to the other of the mould to lay down partially-expanded foam over the bottom of the mould while the mould is in a moulding position. Gas is vented from the interior of the mould and the mould is moved from the moulding position to a curing position remote from the moulding position where the bun cures in the mould.
