Abstract

The present invention provides a tire manufacturing method and system for controlling the profile of a product having one or more elastomeric layers by continuously extruding an elongated element (200) of elastomeric material and The elongated elements (200) are placed on the forming surface (100a) of a circumferentially rotating drum (100) for production.

Description

technical field [0001] The present invention generally relates to tire production. More specifically, the invention relates to the control of product profile by measuring the circumferential extent of the building drum surface between the production of layers of material. Background technique [0002] Tires are generally constructed of multiple layers and components that are sequentially placed on inflatable and contractible building drums. While the building drum may include recesses for accommodating features such as circular beads, circumferentially rotating drums are generally cylindrical in shape having a planar profile in the axial direction. In some known techniques, a layer of air-impermeable rubber is laid onto the building surface of the drum, and one or more carcass plies are placed on the layer of air-impermeable rubber. Each ply extends between opposing side bead portions of the tire, through opposing sidewall portions, and across a crown portion of the tire. ...
