Abstract:
A lamella for use in a vehicle tire vulcanization mold, said lamella having:a) projections (4) and depressions (5), said projections (4) and depressions (5) being defined by said lamella, wherein a height (Z4) of said projections (4) and a depth (Z5) of said depressions (5) extend substantially parallel to a peripheral surface (P) of a tire tread (L) of a vehicle tire to be molded in the vehicle tire vulcanization mold; b) wherein said lamella has a thickness of approximately 0.5 mm; c) wherein each one of said projections (4) has a highest point-shaped location or top (G) correlated therewith; d) wherein each one of said projections (4) have a plurality of walls, each said wall having a wall thickness, wherein said wall thickness thins as said wall extends from a base of said projection (4) to said highest point-shaped location or top (G); e) wherein each one of said depressions (5) has a lowest point-shaped location (K) correlated therewith; f) wherein said projections (4) and depressions (5) are distributed according to a substantially uniform areal division; g) wherein said areal division is defined by dividing lines (T) extending in a dividing line plane, wherein said dividing line plane is positioned between a first plane defined by said tops (G) and a second plane defined by said craters (K); h) wherein said dividing lines (T) are comprised of three sets, wherein said dividing lines within each one of said sets extend parallel to one another; and i) wherein said dividing lines of different ones of said sets intercept one another at an angle of 60Â° so that a grid of triangles is formed.
