Tire manufacturing method cover rubber stamping device used for the manufacturing method, tire rubber sheet member stamping method , and rubber sheet member stamping device

A tire in which at least one side wall is comprised of a first color side wall rubber expressed as characters or lines, a second color side wall rubbers located on both sides in the radial direction of this first color side wall rubber, respectively, and a cover rubber in the second color covering a first-color side wall rubber portion other than the characters or lines, wherein:

• the first color side wall rubbers and their second color side wall rubber are made of a continuous rubber ribbon wound in plural turns, respectively, and the cover rubber is made of a single thin annular rubber sheet.

A method of stamping a rubber sheet member in the annular state on a side face of a body of rotation, wherein:

• a leading end of a long rubber sheet arranged on a tangent of an annular band on the side face of the body of rotation to be a stamping face of the rubber sheet member is held, and the leading end is transferred onto the annular band and pressed and then, the rubber sheet is stamped onto the annular band by rotating the body of rotation around its central axis while applying a tension to this rubber sheet, after the rotation of the body of rotation is stopped, an unstamped portion of the long rubber sheet is cut off, and the unstamped portion to be the rear end of the rubber sheet on the annular band is pressed onto the annular band to stamp the rubber sheet member.

A method of stamping a rubber sheet member on a side face of a body of rotation in the annular state, wherein;

• a rubber sheet extruded through a die is passed through a gap formed by arranging large-diameter sides and small-diameter sides of a pair of truncated conical rollers opposite to each other for rolling, and immediately after rolling of this rubber sheet, the rubber sheet is stamped in the annular state so that the rubber sheet side rolled by the large-diameter side of truncated conical roller is made to correspond with the outside in the radial direction of the side face of the body of rotation while the side rolled by the small-diameter side of truncated conical roller is made to correspond with the inside in the radial direction of the side face of the body of rotation.
