  • Publication number: 20090249597
    Abstract: The invention can firmly and easily remove a finely divided weft piece without leaving the weft piece by constituting a method and an apparatus of removing weft from a cord fabric for a topping sheet in a calender line for topping rubber on a number of pieces of aligned cords by a calender roll. In the midst of transferring a cord fabric (F) transferred to a calender apparatus, weft is finely divided by passing the cord fabric (F) through weft dividing means, thereafter, a plurality of blades (45) arranged movably in a width direction on an upper face side of the cord fabric (F) are reciprocally moved in the width direction over an entire width thereof to be brought into contact with the cord fabric (F), and the divided weft piece (W1) is wiped off to remove by respectively striking respective cords (C) of the cord fabric (F) by the respective blades (45).

  • Publication number: 20090133808
    Abstract: A tire building method and a tire building facility according to the invention attains reduction of an installation space of the tire building facility and substantially equal building cycles for respective building stages to increase building efficiency and facilitate arrangement switching. For attaining these, a step for building a cylindrical carcass band, a subsequent step for building a cylindrical green case, a step for building a cylindrical belt and tread band, a step for combining the green case and the belt and tread band to build the final shape are divided as first through fourth building stages (S1) through (S4) having individual building drums (D1) through (D4) corresponding to the respective steps.

  • Publication number: 20090095065
    Abstract: An improvement is achieved in productivity of a tire by preventing an unacceptably molded green tire, which is produced in a molding process, from flowing to a vulcanizing process. Measures therefor comprise putting an unvulcanized green tire on a mount surface of a mount stage, sticking an information label to a side wall of the green tire with a label sticking device arranged below a through-hole formed in a position, which corresponds to an inside of a bead body of the green tire, on the mount surface, and measuring a weight of the green tire with a gravimeter, which supports the mount stage.

  • Publication number: 20090032181
    Abstract: In obliquely cutting a belt band-shaped material (B) to a predetermined length and joining belt material pieces (b) as cut to fabricate a belt member (B10) for a tire, according to the invention, a space, in which an apparatus is mounted, is decreased, a belt member of good quality and high accuracy of joining is manufactured, a cut processing section (A1) for a band-shaped material and an alignment processing section (A2) for belt material pieces as cut are arranged in parallel, in the cut processing section, whenever the band-shaped material (B) is intermittently forwarded, a leading end portion of the band-shaped material is held on a holding table 40 and obliquely cut by a cutter unit (30), the belt material pieces (b) as cut are attracted and held on an underside of a holding member (53) of a transfer unit (T) to be transferred onto and placed on an alignment conveyor (60) with oblique cut ends trued up, and in the alignment processing section, whenever a belt material piece (b) is transferred, the align
