Abstract: A method for manufacturing a tyre is provided, in particular a run-flat tyre. The method includes providing a drum with a first shrink section and a second shrink section. Each shrink section is provided with a shrink surface that is radially movable. The method includes moving the shrink surfaces radially inwards with respect to the central axis from a level position to a shrink position in which the drum, at the shrink surfaces, has a circumference with a second diameter that is smaller than the first diameter, while creating a partial vacuum between the shrink surfaces and a first tyre layer at the first shrink section and the second shrink section. The method further includes shrinking the first tyre layer onto the shrink surfaces in the shrink position under the influence of the partial vacuum. A drum for use in the aforementioned method is also disclosed.

Abstract: A method for manufacturing a tire includes the steps of preparing strip sections, laying down a first series of the strip sections on a toroidal support, applying at least primary portions of annular reinforcing structures against end flaps of the strip sections of the first series at axially-opposite positions relative to an equatorial plane of the toroidal support, and laying down on the toroidal support at least one second series of the strip sections. Each strip section extends in a substantially U-shaped configuration around a cross-sectional outline of the toroidal support. First series strip sections are circumferentially distributed according to a pitch corresponding to a multiple of their width. Second series strip sections extend between consecutive first series strip sections and include end flaps overlapping respective primary portions of the annular reinforcing structures at an axially-opposite position relative to end flaps of the first series strip sections.

Abstract: A fully automatic machine for producing "green tires" or unvulcanized tire carcasses, especially suitable for making tubeless tires. The machine comprises a plurality of interconnected and dependent assembles or stations where specialized operations, normally done semi-automatically or by hand, are carried out by mechanical devices acting in sequence. The machine includes, a plurality of conventional tire building drums continuously moving between horizontally disposed, stationary table assemblies where innerliner and chafer strips, and first and second ply material are successively wrapped on the drums as they move across the table on which the material is positioned. The wrapped drums from these assemblies, are sent to turret units where they are accurately positioned for receiving beads, tread cushion, stitching, strips of whitewall, if required, and are discharged from the collapsed drums for removal and storage. The stripped drums, or drums from which tires are removed, are automatically expanded and recycled through the assemblies for building more tire carcasses.

Abstract: A manufacturing device for an unvulcanized band-shaped rubber member is provided. A position sensor detects, across a width direction of the band-shaped rubber member, leading and trailing ends of the band-shaped rubber member placed in a flat state on a conveyor, holding portions arranged side by side in the width direction hold at least one of the leading or trailing ends, with movement portions allowing the holding portions to move individually in a front-rear direction, the leading and the trailing ends are held by the leading and trailing end holding mechanisms, respectively, and a control unit controls a displacement of the movement portions in the front-rear direction based on data from the position sensor and a target length to adjust elongation in the front-rear direction at or near a held portion held by each of the holding portions to achieve the target length of the band-shaped rubber member.
