Abstract

Moulds or cores comprised of a series of mutually displaceable parts, for use in moulding hollow articles from cellulose hydrate, cellulose esters, gelatin, or other organic plastic masses, are provided with an elastic cover, e.g. rubber, in order to cover the meeting edges of the separate mould &c. parts. The cover employed is chemically inert with respect to the mass being moulded.
