Embodiment Construction

[0036]With reference to the accompanying drawings, an apparatus for the manufacture of pneumatic tires for vehicle wheels is designed to carry out the method according to the invention and is generally indicated by the reference number 1 .

[0037] The present invention aims to produce Image 6 A pneumatic tire, generally indicated at 2, substantially comprising a carcass structure 3 of substantially toroidal profile; a belt structure 4 extending circumferentially around the carcass structure 3; applied at a radially outer position a tread band 5 to the belt structure 4; and a pair of sidewalls 6 applied transversely to opposite sides of the carcass structure 3, said sidewalls each extending from a side edge 5a of the tread band 5 until proximately along the tire A so-called bead 7a located at each radially inner edge of 2.

[0038] The carcass structure 3 comprises a pair of annular anchoring structures 7 integrated into the beads 7a and each constituted by a so-called bead ...

Abstract

The invention relates to a method and an apparatus for manufacturing a pneumatic tyre. The apparatus is characterized in that: an anchoring structure (7) anchored to a tyre bead (7a), a carcass ply (10), a belt structure (4) and / or other annular composite parts which are all on an assembly drum (16) are assembled with a liner (12), a side wall (6), side wall plugins (11), a bottom belt plugin (14) or other annular elastomeric parts in order; an one-piece structure which is stored in a mobile storage device (26) is manufactured by each side wall plugin (11), and the side wall (6) or each bottom belt plugin (14) in a maintenance site (19) which is dividually operated with the assembly drum (16); an actuating member (47) which is operated on the mobile storage device (26) sends the annular elastomeric parts (6,11,14) to the assembly drum (16) from the maintenance site (19); and a transferring member picks up the annular elastomeric parts (6,11,14) from the storage device (26) and transfers them to the assembly drum (16).

Description

[0001] This divisional application is based on the divisional application of the Chinese patent application with the application number 200580052433.0, the application date is December 28, 2005, and the invention title is "Method and device for manufacturing pneumatic tires". technical field [0002] The present invention relates to a method of manufacturing a pneumatic tire for a vehicle wheel. [0003] The invention also relates to a device for manufacturing pneumatic tires for wheels. Background technique [0004] Pneumatic tires generally comprise a carcass structure comprising at least one carcass ply internally coated with an innerliner, commonly referred to as a "liner"; and having respective opposing end stops The end stoppers are twisted annularly around annular anchoring structures, each generally consisting of a substantially circumferential annular insert to which at least one filler insert is applied radially of the annular insert. external location.
