    Abstract: A method and system for manufacturing a tyre tread with lugs, the tread having a tread base, and a number of lugs projecting upwards from the tread base; the method having the steps of: preparing a green-rubber blank tread of constant thickness; applying rubber blocks to the areas of the blank tread where the lugs are to be formed, each block varying lengthwise in cross section, so it is thinner at the centre and thicker at the side; and curing the blank tread, together with the blocks, in a curing mold negatively reproducing the pattern of the tread.

    Abstract: A pneumatic tire which facilitates separation of a rubber layer and is excellent in recyclability and retreadability and a method of scrapping the same. A pneumatic tire comprises a partition layer buried adjacent to a rubber layer, the partition layer including at least one cord repeatedly bent to turn around at its bent portion and arranged in a plane and rubber portions interposed between adjacent portions of the cord. Herein, the cord is arranged in a direction intersecting with the tire circumferential direction. The cord of the partition layer is pulled in an in-plane direction of the partition layer to sequentially cut the rubber portions interposed between the adjacent portions of the cord. The rubber layer adjacent to the partition layer is thus separated.

    Abstract: A method for the cold retreading of a tire comprising the following steps: a removal step, during which the tread is removed from the tire in order to expose an equatorial surface of a casing of the tire; a deposition step, during which a cushion and a pre-cured tread strip provided with a tread pattern are deposited around the equatorial surface of the casing; and a curing step, wherein the cushion arranged between the casing and the pre-cured tread strip is cured. The cushion is manufactured with a compound comprising 1 to 30 phr of at least one conductive material having a specific surface area which is greater than or equal to 300 m2/g and is chosen among graphite and graphene. The curing step comprises a connection step, wherein said cushion is connected to a heat/power source.
