STRIP AND PROCESS FOR PRODUCING SAME, AND PROCESS FOR MANUFACTURING PNEUMATIC TIRE |
摘要 |
A strip of a thermoplastic elastomer to be wound spirally on a cylindrical drum for forming an inner liner for a tire having a shape close to a finished sectional shape is provided. The strip is formed of composite layers of (A) a first layer made of a styrene-isobutylene-styrene triblock copolymer and (B) a second layer containing at least one of a styrene-isoprene-styrene triblock copolymer and a styrene-isobutylene diblock copolymer. The strip further has a strip main body and ear portions arranged on opposite sides thereof. The strip main body has a thickness (T1) of 0.05 mm to 1.0 mm. The ear portions have a thickness (T2) thinner than the thickness (T1) of the strip main body and a width (W2) of 0.5 mm to 5.0 mm. This ribbon-shaped strip reduces unevenness of the surface of a sheet formed by the opposite ends of the strip when manufacturing an inner liner. |
