Process for the manufacture of laminated material reinforced with fabric or cord; process for manufacturing a reinforcing element for a tire; and tire fitted with a tread for contact with the ground and a carcass fitted with a pair of ring beads, a pair of side elements that extend radially out of the beads, a pair of reinforcing plies covering the ring beads

摘要

A method and apparatus for fabricating a rubberized wire sheet is described. A plurality of wires 200 pass through an extruder 10. The extruder 10 coats each wire 200 with rubber 210 to form rubberized wires 201. The plurality of rubberized wires 201 pass through a calender roller system 50 to form them into the rubberized wire sheet 202 having a desired width. The method permits the manufacture of wire reinforced sheets 202 whereby the wires 200 may be coated with an extruded rubber compound and then encapsulated by a calender compound differing in chemical composition from the extruded rubber compound. The above-described sheet can be used in the manufacture of reinforcing components of a tire 20. IMAGE
