摘要

PROCESS AND APPARATUS FOR MANUFACTURING TIRES AND LOCKING MEMBERS FOR ANNULAR ANCHORAGE STRUCTURES OF A TIRE CASING SLEEVE IN PROCESS. A carcass ply (3) is applied around an outer surface (14) of a construction drum (10) according to an application diameter (D1) greater than the tire insert diameter (OD) ( 2). An annular anchor structure (5) defining the socket diameter (OD) is coaxially engaged around each of the end flaps (3a). An outer sleeve (24) comprising at least one strap structure (7) possibly associated with a tread (8) is arranged in an axially centered position around the shell sleeve (21) applied to the construction drum (10). ). By axially approximating the two halves (10a) forming the construction drum (10), the housing sleeve (21) is modeled in a toroidal configuration to determine its application against a radially internal surface of the outer sleeve (24).
