US 2021/0070000 A1 · SIPE BLADE ASSEMBLY

Abstract

The present invention relates to a set of mould elements comprising main blades and secondary blades, intended to be added to a mould for vulcanizing a tread of a tyre, said mould elements being capable of moulding cuts in the tread, characterized in that a main blade comprises at least one assembly means for assembling a secondary blade, said assembly means comprising two series of at least one protrusion arranged facing one another. It is thus possible to ensure a relative positioning and an assembly that can withstand mechanical stresses over the entire height of the blade during moulding/demoulding, while minimizing the volume of material added. This assembly is barely visible on the tyre.
