    摘要： A tire manufacturing method to obtain a base tire superior in uniformity when the base tire has a cushion gum applied thereon. In this process of tire manufacture, the thickness from a belt, which is located in the outermost layer of the base tire having an application surface for the cushion gum, to the application surface is measured along the circumference of the base tire so as to detect a maximum thickness position. Then the circumferential winding of the cushion gum extruded from an extrusion molding unit is started from the maximum thickness position.

    摘要： Embodiments of the invention include methods for supporting a recessed void during retreading operations. Such methods include the steps of providing a tread having a top side and a bottom side, the tread including a recessed void recessed below the top side of the tread. Such methods also include the step of arranging the tread around an outer circumference of the tire carcass in a desired position to form an assembled retreaded tire. Such methods further include the step of arranging a removable circumferential band around the assembled retreaded tire positioned over top the recessed void and the top side of the tread. Such methods further include the steps of placing a curing membrane around at least a portion of the tire and the circumferential band and curing the retreaded tire with the circumferential band contained within the curing membrane.

    摘要： The present utility model proposes a configuration applied to envelope for tire retreading in a cold retreading process. Two part envelopes are known in the prior art. However, known forms of sealing between the pieces are unsatisfactory, either because problems arise in connection with the seal or because they reduce the service life of the envelope. With the intention of overcoming these limitations, the present utility model proposes an envelope (20) comprising three parts (22, 24, 26), wherein one flap (224) of the first part (22) has a free end with a different cross section (224b), wherein a flap (244) of the second part (24) has a free end with a different cross section (244b), and wherein the third part (26) has an elastic ring form of sufficient width to cover the different cross section (224b) of the flap (224) of the first part (22) and the different cross section (244b) of the flap (244) of the second part (24).
