FIELD: car industry.

SUBSTANCE: device relates to car industry, particularly to equipment for cutting metal wire tires along two or more cutting lines for tyres with metal cords. The device comprises a metal cylinder with pockets and sharp circular metal blades positioned in accordance with these pockets. Furthermore, the blade width is larger than the pocket width. The blade edges are formed by one conic and one flat surface positioned at a right angle in relation to the circular blades and metal cylinder rotation axis. The flat blade surfaces are turned towards each other. Each metal circular blade is installed so that it can rotate freely on a separate independent beam. The rotation axes of all beams are parallel to each other and to the metal cylinder rotation axis. Each beam with a metal circular blade has an independent mechanism for pressing the circular blade to the corresponding pocket in the cylinder.

EFFECT: high-quality reliable cutting along two or more cutting lines of the metal cord tyre.
