PNEUMATIC BUS, PROTECTOR LAYER AND PROTECTOR UNIT, CONTAINING A TORQUE CUT, AND ALSO A LAMEL PLATE FOR ITS MANUFACTURE

摘要

A pneumatic tire (90), a tread band (100) for a pneumatic tire, or a tread block (200) for a tread band or for a pneumatic tire; which is provided with sipes (21), at least some of the sipes (21) having an open top end (TOP) to the surface of the tread block (200). An intersection of the sipe (21) with a surface (107a, 107b) that is geometrically congruent and parallel with the surface of the tread block (200) and arranged a depth (d) apart from the surface of the tread block (200) into the tread block (200) forms a curved line (210). At least a first sipe (21) of the sipes (21) is shaped in such a way, that at all depths (d) within a range from the open top (TOP) of the first sipe (21) to a first transition depth (d1), the curved line (210) comprises at least one deflection point having (22a) an inner corner (220a) that has a radius of curvature under 0.3 mm. A lamella plate (43, 53, 63, 73, 83) for manufacturing the pneumatic tire (90), the tread band (100), or the tread block (200). Use of the lamella plate (43, 53, 63, 73, 83) for manufacturing a tread block (200), a tread band (100), or a pneumatic tire (90).
