A lamella strip(3) comprising two shanks(4,5) folded back onto each other is fixed in the molding tool(1) at the fold(6). Both free shanks extend away from the tool outer surface and form a feature of the latter which produces a fine cut in a tire tread molded in the tool. The two shanks(4,5) may have similar or different lengths(t1,t2) extending away from the tool face. One or both shanks may follow a varying path along the fold line(6), e.g. a sine wave or a zig-zag, and/or along the length of the free shank from the fold line axis. An independent claim is included for a process for manufacturing a vehicle tire with profiled tread having fine cuts in which an unvulcanized tire tread preform of suitable shape is pressed during molding against a tire mold surface containing one or more protruding folded lamella so that in each case both shanks penetrate into the rubber to produce a fine cut before tire vulcanization. |
