Method for applying electrical conductive thread on carcass insert for improving conductivity of side wall of vehicle tire, involves forming conductive thread of elastomeric material, and processing carcass insert using calendering process

摘要

The method involves forming a conductive thread (2) with a smooth outer surface. The conductive thread is continuously unwound from a cylindrical coil (1) by applying constant tensile stress, where the thread is wound on the cylindrical coil in a coil-shape and held in a position by a net-shaped elastic holding unit (3), where the conductive thread is made of electrically conductive elastomeric material. A carcass insert is subsequently processed using a calendering process, where the holding unit exhibits mesh size of about 0.2 to 3 cm.
