An intersection of the sipe with a surface that is geometrically congruent and parallel with the surface of the tread block and arranged a depth apart from the surface of the tread block into the tread block forms a curved line. A first sipe is shaped in such a way, that at all depths (d) within a range from the open top of the first sipe to a first transition depth, the curved line includes at least one deflection point having an inner corner that has a radius of curvature under 0.3 mm. A lamella plate for manufacturing the pneumatic tire, the tread band, or the tread block. Use of the lamella plate for manufacturing a tread block, a tread band, or a pneumatic tire.",
