DEVICE FOR TIRE CASING CUTTING Russian patent published in 2008 - IPC B29B17/00 

FIELD: technological processes, mechanics.

SUBSTANCE: device for cutting of tire casing with metal cord is arranged in the form of metal roller with groove and disk metal knife. Thickness of knife is more than the width of groove in metal wheel, and conical surfaces of knife blade that form cutting edge contact with external edges of the groove. Internal side surfaces of the groove are arranged as conical, surface of roller with the groove is formed with conical surfaces that are separated by the groove. At that in section of device with the plane, in which rotational axes of knife and roller are located and that passes through zones of contact of conical surfaces of knife and roller, generatrices of conical surfaces of knife blade and conical surfaces of roller along groove edges are installed at the angle close in value to 90°, and generatrices of internal side conical surfaces of the groove and conical surfaces of the knife are installed at the angle close to the value of 45°.

EFFECT: increase of efficiency and stability of cutting, reduction of device dimensions and probability of tire casing noncutting.
