    Abstract: A tire belt (18) for a pneumatic tire comprising a rubber strip (20) and reinforcement cords (22) embedded in the rubber strip (20). The strip (20) comprises two or more portions made of different compounds optimized respectively towards different desired belt properties. These portions can comprise an annular coating (24) surrounding the reinforcement cords (22) and a ribbon (26) surrounding the annular coating (24). The annular coating (24) can be made of a compound optimized towards one set of desired belt properties ( e.g. , good rubber-to-cord adhesion) and the ribbon (26) can be made a different compound optimized towards another set of desired belt properties ( e.g. , good thermal aging stability, cut growth performance, etc.).

    Abstract: A tendon for use in posttensioning prestressed concrete comprising a multi-wire strand (12) wherein individual peripherally abutting wires (16) define both internal (20) and external (18) interstices between themselves and a central wire (14), the external interstices (18) being substantially fully filled with a dielectric plastics material such as a high molecular polyolefinic material e.g. high density polyethylene. The plastics material forms an encasement (22) completely surrounding the strand and providing it with a smooth outer surface of circular cross-section. A friction-reducing, grease-like material (28) is coated on the encasement and the entire structure is thereafter enclosed in a plastics jacket (32). The above structure is formed by progressively extrusion coating the wire strand with the dielectric plastic, coating the strand with the grease-like material and subsequently applying to the thus coated composite with a plastics material to form the jacket.
