for a stereotype and a sullage piece on the top of it to be
cast therein. (3.) Apparatus according to Claim 1, charac-
terized by a flexible metal shield fitting over the matrix, when
the mould is closed, to prevent metal getting between it and
the cope, and to assist the matrix-holders to peel the margins
