摘要： Apparatus for building a tire having a circumferentially inextensible belt, and particularly a multi-condition tire building drum providing in an intermediate condition, a high crown firmly supported for stitching a cylindrical tire band, a radially expansible sleeve secured radially on and extending axially between a pair of drum end assemblies movable toward and away from each other and cooperating with the sleeve to form a chamber into which air is admitted to expand the sleeve into toroidal form as the end assemblies are moved toward one another, bead locating segment assemblies adjacent to and axially outboard of the sleeve ends to locate beads of the tire in firm axial and concentric position as the tire is shaped from a cylindrical to a toroidal form and particularly useful in securing the beads in proper location during conventional stitching operations. The drum features expansion of the internal supporting segments by rotation of scroll plates each having a plurality of spiral cam grooves by which the segments are moved radially inwardly and outwardly.

摘要： A drum for building and shaping blanks for radial-ply tyres comprises two co-axial bead holders at least one of which has an extension drum which is co-axial therewith, is secured thereto and has the same outside diameter. the extension drum acts in part as a support for a tyre band while the latter is being secured to the bead holders for shaping. The bead holders are movable axially relative one to the other to position the tyre band for shaping and each is provided with radially movable segments to which end portions of the tyre band are secured in airtight manner. During relative axial movement of the bead holders towards each other, a gaseous medium is introduced into the space bounded by the bead holders and the tyre band so that the band is curved outwards to form a tyre blank.

摘要： 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 assemblies 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 turrent units where they are arcuately 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.

摘要： A tire building apparatus having an expandable drum defined by a plurality of circumferentially arranged deck segments each comprising a plurality of peripherally extending support members movable radially and circumferentially relative to each other to provide supporting surfaces of different radii with adjacent outer end portions of adjacent supporting members being interleaved, and in which the outer end portions of the supporting members are of less cross-sectional area than the cross-sectional area of intermediate portions of the supporting members to provide supporting members of increased length over prior known construction and to provide in the expanded position of the expandable drum a circumferentially extending supporting surface of a maximum length substantially equal to the circumferential length of the interleaved outer end portions of the supporting members and intermediate portions of the supporting members. The expandable drum, as aforenoted, in which the deck segments comprise deck former members for supporting individual supporting members, in which the deck former members have positioning surfaces for engaging radial inward surfaces of the supporting members for disposing the latter in predetermined positions upon expansion and contraction of the expandable drum, and in which the supporting members may or may not be provided with outer end portions of the supporting members as first above described. A tire building method in which tire beads are disposed inwardly of opposite outer end portions of elongated hollow tire carcass material, displacing the center portion of the tire carcass material to form the same into the true shape of the crown portion of the carcass of a cured tire, and encasing tire beads in the outer end portions of the tire carcass material.

摘要： A tire building drum has adjacent respective edges of a cylindrical drum section a plurality of radially movable segments. The circumferential outer surface of the segments forms an arcuate surface. A plane of separation between the segments and the drum section edge intersects the arcuate surface at approximately the most radially inward portion of the arcuate surface. The tire building drum is particularly useful for positioning the bead wire ring during the turn-up of a metal reinforced carcass ply.
