    Abstract: Molding element for molding and vulcanizing a tire tread, having a tread surface contacting the ground when rolling, having a molding surface to mold part of the tread surface and a blade of length and of height H to mold a sipe or a groove in the tread, having a rounded end extending along its length in a direction of extension X. The molding element has two cutting means to cut a cover layer applied to a green form of the tire, positioned on either side of the blade at a certain distance from this blade, each cutting means having a cutting edge extending in the direction of extension, making an acute angle α in a sectional drawing perpendicular to direction of extension X able to cut the cover layer, the distance between this cutting edge and the molding surface being lower than the height H of the blade.

    Abstract: A method and an apparatus for forming a carved groove of a green tire capable of forming a carved groove of a necessary depth without being influenced by variation of outer diameters of the green tire is provided. In a method and an apparatus for forming a carved groove for a lug groove with a cutter on an outer circumferential surface of a green tire before curing, a distance sensor is moved along a portion to be carved on the outer circumferential surface of the green tire to measure outer diameters of the portion to be carved, cut shape data for a green tire having an ideal shape stored in memory beforehand is revised on the basis of the measured outer diameters, and the cutter is moved in accordance with the revised cut shape data for carving.

    Abstract: A method and apparatus for grooving a tire tread in which a computerized numerical controller regulates the positional relationships between the tire and a hot cutting knife. The controller, through a plurality of servo motors, causes the tire to rotate in a vertical plane while effecting lateral and rotational movement of the cutter knife in each of two planes. During the cutting operation, the controller regulates the temperature of the cutting knife in accordance with the contour of the cut and the rate at which it is being made. Additionally, the computerized numerical controller is operator-programmable, providing for the generation of a program while the knife is caused to trace a tread design. The method and apparatus achieves simultaneous five-axis control of the tire grooving operation with concurrent regulation of the knife temperature.
