Abstract

223,189. Anode Rubber Co., Ltd., (Assignees of Klein, P.). Oct. 11, 1923, [Covention date]. Moulding india-rubber. - Homogeneous deposits of india-rubber are obtained from latex by electrophoretic precipitation upon a permeable non-conducting surface or mould surrounding the anode, whereby the gases evolved at the anode can escape without interfering with the rubber deposit. The latex may be previously purified or concentrated, and preservatives, organic dyes, and sulphur may be added to it. The anode, which may be of metal or carbon, is either embedded m the permeable substance, consisting preferably of gypsum or unglazed earthenware, or is separated from it by a body of latex or other electrolyte. In the manufacture of shaped articles the anode and cathode may be moved relatively to one another to obtain a deposit of even thickness, or the cathodes may be so placed or to give a thicker deposit on any desired part of the mould. Fig. 2 shows an apparatus in which part of the mould b is protected by an insulating covering t so that no deposition occurs. In this modification the latex receptacle itself constitutes the cathode k. Fig. 3 shows an apparatus for the manufacture of sheets, comprising a revolving drum b, for example of gypsum, surrounding the anode a. The deposited sheet m is detached continuously from the upper part of the drum. In another modification an endless band of material to which the rubber does not adhere, e.g. fabric coated with cellulose acetate, passes over the drum and receives the deposit, which is continuously removed from its upper part.
