MOULD FOR VULCANIZING WINTER AND ALL-SEASON TIRES OF VEHICLES, METHOD FOR MANUFACTURING MOULD FOR VULCANIZATION AND PNEUMATIC VEHICLE TIRE

摘要

FIELD: transportation.;SUBSTANCE: mould has, on the inside, moulding surfaces (3) with a negative tread profile, comprising elements (7) of the negative profile for moulding a positive tread profile containing elements of the positive profile of the vehicle tire (4) to be vulcanized. Wherein lamella plates (9) located in the negative profile elements (7) form slit-like grooves in the elements of the positive profile of the vehicle tire (4) to be vulcanized. In addition, at least one ventilation slot (11) is located within the negative profile element (10) of the shoulder area as a ventilation means (5). This ventilation slot (11) extends parallel to the lamella plate (9) located in this element (10) of the negative profile of the shoulder area and at a distance from it. Wherein at least one cylindrical ventilation means (12) is additionally located only axially, externally with respect to this ventilation slot (11).;EFFECT: improving the quality of manufacturing products.;17 cl, 5 dwg
