    Abstract: A method and an apparatus for manufacturing a tire capable of preventing air from remaining and suppressing the occurrence of bare and flow crack, which will reduce the durability of a product tire, by grinding down a step formed at the overlapped portion of a tire component to appropriate the cross sectional shape of the overlapped portion. The apparatus (1) comprises a molding stand (2), a rubber strip extruder (3), and a pressing roller (4). A ribbon-shaped rubber strip (5) extruded from the rubber strip extruder (3) is spirally wound while overlapping and stuck on the molding stand (2) to form the specified tire component. The step (8) at the overlapped portion (7) exposed to the outer surface of the tire component is ground down by using the pressing roller (4) disposed oppositely to the molding stand (2) at a specified slip angle alpha relative to the extending direction of the stuck rubber strip (5) and heated to a temperature in a plasticization temperature range to smoothen the outer surface of the tire.

    Abstract: [PROBLEMS] To provide a method for forming a green tire which can be employed for preventing the occurrence of blasting by the satisfactory cooling of an unvulcanized rubber ribbon, and a device for cooling a green tire for use in the method. [MEANS FOR SOLVING PROBLEMS] A method for forming a green tire, which comprises, at least in the process from the start to the finish of the winding of an unvulcanized rubber ribbon (R), blowing a cooled gas continuously to the whole of the region specified by the range in the width direction corresponding to the whole width (W) of the unvulcanized rubber member (5) and a prescribed angle range (theta) in the peripheral direction of the surface of a green tire being rotated on the way of forming, to thereby cool the unvulcanized rubber ribbon (R) having been already wound.

    Abstract: A tire printing device includes a printer head (2), positioned near a rotating tire (1), that ejects and applies coating material, an unevenness detection sensor (3) that detects a predetermined raised/recessed character on the surface of the rotating tire (1) and a PC (10) that sets the origin of rotation of the tire (1) based on a signal detected by the unevenness detection sensor (3) and synchronizes the operation start time of the printer head (2) with the origin of rotation in order to maintain a constant relationship between the position of the raised/recessed character and the position of application of the coating material. Desired printing is performed by the printer head (2) ejecting and applying the coating material onto a surface of the rotating tire (1) after the rotating tire is mounted on a rim and inflated to a regular shape by being applied with an internal pressure.

    Abstract: A tire and a method of producing the tire, where the tire has a tread layer constituted of tread rubber and a conductive belt provided in an intermediate portion in the width direction of the tread rubber. The tread rubber is constructed from a low conductive continuous rubber ribbon circumferentially wound plural times, and the conductive belt is constructed from a highly conductive thin annular rubber sheet. The conductive belt is provided so as to extend in a width direction region from a part of a top surface of a first tread rubber portion up to a part of a bottom surface of a second tread rubber portion. The structure above improves tire uniformity and enables the tire to be produced in a multi-kind mixed production system. Further the thickness in the width direction of the conductive belt can be constrained to minimum, and a conductive path from the belt to a tread surface can be formed reliably and at low cost.

    Abstract: By turning toward the radially outer direction a turned-up region (R) of a tire component (T) by reciprocating turning fingers (67), and by positioning the reciprocation centre (the base of a short finger part 68) of the turning finger at the immediate vicinity of the departing point of the tire component from a bead-locking device (46), the compressing force provided at the turned-up region (R) in the vicinity of the bead (B) is effectively decreased, and therefore the generation of creasing is controlled.
