Title:
How to manufacture a self-expansion tire
Document Type and Number:
Japanese Patent JP5946632
Kind Code:
B2
Abstract:
A method of constructing a self-inflating tire assembly includes molding in an air tube-receiving groove within a green tire carcass wall, the groove having an access opening, primary internal groove chamber and a secondary expansion groove chamber adjacent to and communicating with the internal groove chamber. A groove partial passageway is molded with the groove at a prescribed groove outlet location and extends from the groove partially through the tire carcass wall toward the tire cavity. A tire carcass wall barrier of reduced section between the partial passageway and the tire cavity is removed in a post-cure operation to create a through-bore from the groove to the tire cavity. A pump assembly inserts into the tube-receiving groove in a post-cure procedure with an outlet passage tube from a pump assembly outlet device extended through the through-bore to the tire cavity.
