  • Pulp forming machines
    Patent number: 6409885
    Abstract: A pulp forming machine includes a forming head including a platen and plurality of mould carriers. The mould carriers are connected to the platen by mould carrier support means which allow the mould carrier and the platen to transmit forces perpendicular to the general plane of the platen but allow movement and expansion of each mould carrier in the general plane of the platen. Mould carrier to mould carrier locating means locate the mould carriers of opposing platens during the forming process to align moulds carried on the mould carriers with cooperating moulds of the cooperating platen.
