The equipment comprises a matrix (2) with a cavity (11) containing an elastic lining element (13), and a die (10) with at least one relief impression (3) which matches the cavity and is delimited by cutting edges (5) connected by chamfered surfaces (8) to an upper section (7). Between the cutting edge (5) and chamfered surface (8) the die imprint has a flat surface (9) which aligns with a lip (14) on the cavity liner (13).
