For this purpose a number of cores are first cast of some material, such as stearine, spermaceti, wax, or other substance that will melt at a low temperature. These fusible ; cores are afterwards immersed in the gelatine in a liquid state. By this 15 means the cores will be covered with a film of gelatine of the desired thickness, and when the gelatine is dry heat, is applied to melt out the fusible cores, thus leaving the capsules empty and ready for use. For the production of the fusible cores a mould frame is proyided, fitted with transverse blocks set in pairs, each of which has cut or formed in its side 20 a half mould of the form of the core desired to be produced, so that when brought together each pair forms a series of complete moulds, one of each pair being moveable for the purpose of delivering out the cores when formed. This mould frame is run on a railway under a vessel containing the substance
