Patent GB-389531-A (GB)
Title: Improvements in or relating to the moulding of articles of or containing rubber or other organic substances
IPC: B29C37/00
Filed: 1931-09-19
Abstract: Relates to a method for reproducing on rubber or like articles a surface finish corresponding with the surface finish of an original rubber article.  The original rubber article may be used directly as a former, in which case the markings would be inverted or in mirror fashion.  Preferably, however, the original rubber article is used as a mould to produce negative replicas which are then used to produce positive copies of the original.  The copies may be produced by dipping, spreading moulding or electrophoresis from aqueous emulsions or dispersions or solutions in organic solvents of such organic materials as rubber (including artificial, coagulated, vulcanized, waste or reclaim), guttapercha, balata or similar resins. Concentrates such as described in Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], may be used.  Since rubber or the like is substantially non-conducting, electrophoresis can only be employed when conducting replicas are first made.  If it is necessary to distend or make rigid the original rubber article, this may be done by introducing air other fluid, or powdered material such as soapstone, unbaked clay, plaster of Paris, or sulphur either alone or mixed with waxes or other materials. Rigidity may be attained by freezing the rubber article or by vulcanization in a bath of molten sulphur.  In some cases, it may be sufficient to secure the article, e.g. by adhesion, to a rigid backing.  In reproducing such articles as balloons or surgeon's gloves, the article is turned inside out and filled with plaster of Paris, a positive casting being made from the plaster of Paris negative.  This positive is used to produce more durable negatives, e.g. of metal or ceramic material, on which the copies of the original are formed.
