Abstract

276,395. Sturmey, J. J. H. April 19, 1926. Moulding pulp. - In a process for moulding hollow articles from pulp as described in Specification 115,587, the articles are made waterproof and rigid by depositing in the known manner on the pulp fibres a material, e.g. aluminium resinate which, after being fused and melted in the mould and allowed to set, remains rigid at a temperature well above the boiling point of water.
