METHOD AND APPARATUS FOR MANUFACTURING A RUN-FLAT TYRE FOR VEHICLE WHEELS

摘要

In the manufacture of run-flat tyres, annular reinforcing inserts (11) are applied through spiralling of a continuous elongated element of elastomer material on a service drum (22) associated with a building station (16) engaging a primary drum (14) on which the carcass structure (3) is made. An annular transfer member (26) picks up the annular reinforcing inserts from the service drum (22) onto transfer them to the primary drum (14).
