VULCANIZING MOULD FOR WINTER AND ALL-SEASON VEHICLE TYRES, METHOD FOR PRODUCING THE VULCANIZING MOULD AND PNEUMATIC VEHICLE TYRE

摘要

The invention relates to a vulcanizing mould (1) for winter and all-season vehicle tyres (4), which has on the inside moulding surfaces (3) with a negative tread profile comprising negative profile elements (7) for moulding the positive tread profile comprising positive profile elements of the vehicle tyre (4) to be vulcanized, wherein sipe blades (9) are disposed in the negative profile elements (7) are create sipes in the positive profile elements of the vehicle tyre (4) to be vulcanized, and wherein at least one venting slit (11) is disposed within a shoulder negative profile element (10) as a venting means (5), wherein this venting slit (11) runs parallel to and at a distance from a sipe blade (9) disposed in this shoulder negative profile element (10), and wherein at least one cylindrical venting means (12) is additionally disposed only axially outwards with respect to this venting slit (11). The invention also relates to a method for producing the vulcanizing mould (1) and to a pneumatic vehicle tyre.
