A coated wire includes a steel alloy coated with a coating comprising one or more amino alkoxy-modified silsesquioxane compounds selected from the group consisting of an amino alkoxy-modified silsesquioxane, an amino/mercaptan co-alkoxy-modified silsesquioxane, an amino/blocked mercaptan co-alkoxy-modified silsesquioxane, or a salt of one or more thereof. A rubber composition and a process for coating wire is also disclosed.

Methods for treating the surface of a cured inner liner are disclosed. By use of these methods a treated, cured inner liner is produced which has a lower surface with increased adherability to other materials (e.g., adhesives). Treated, cured inner liners resulting from such methods as well as tires containing the treated inner liners.

A polyurea comprises at least urea base units of formula —NH—CO—NH— and additional units. The additional units comprise at least, on the one hand, a secondary alcohol functional group and, on the other hand, an ether, thioether or secondary amine functional group in the alpha position with respect to the secondary alcohol functional group. Such a polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example, glass or metal, to an unsaturated rubber or as corrosion-resistant protective coating for a metal substrate. Metal reinforcers, such as thread, cord, film or plate, coated can also be coated with such a polymer.

A manufacturing method of a bead core of the present disclosure comprises an annular body forming step of winding a strip member formed by coating one or more bead wires with a coating resin to form an annular body, and a resin coating step of coating the annular body formed in the annular body forming step with a resin. The resin is a resin different from the coating resin.

A foldable tire includes a tire main body provided at two edges thereof with two tire beads respectively. A plurality of rings are disposed in each of the tire beads. Each of the rings has a reinforcing core, which includes a plurality of flexible steel filaments helically entwined with each other and has a diameter ranging from 0.2 millimeters to 0.5 millimeters, and a cladding layer clothing the reinforcing core, so that the reinforcing cores located in each of the tire beads are separated from each other.

Provided is a rubber-coated cord manufacturing technique with which the occurring of rubber spew can be prevented and waste in the form of scrap can be reduced during a rubber-coated cord manufacturing step, and with which the burden on an operator can be reduced and a high-quality rubber-coated cord can be stably produced. This rubber-coated cord manufacturing device comprises: an extrusion head that coats rubber on the surface of a cord, the extrusion head including a screw rotation type extruder which extrudes rubber, an insertion port into which the cord is inserted, and a flow path of rubber which has been extruded from the extruder; a cord supply device that supplies the cord to the extrusion head; a rubber-coated cord winding device that winds a rubber-coated cord which has been coated with rubber by the extrusion head; and a head pressure controller that controls the head pressure of the extrusion head. The head pressure controller performs control to maintain the head pressure at a prescribed level by feeding back to the extruder the monitoring results of the head pressure while the cord is coated with the rubber, and adjusting the rotation speed of the screw.
