Abstract: A robot arm having seven axes of actuation imparts to a toroidal support a circumferential distribution motion about its own geometric axis simultaneously with controlled transverse distribution displacements in front of a dispensing organ of a strip of elastomeric material. The strip thus forms a plurality of turns, the orientation and mutual superposition whereof are controlled in such a way as to control the thickness variations to be conferred to a component of a tyre being manufactured, based on a pre-determined laying scheme pre-set on an electronic computer. The rotation of the toroidal support is controlled in such a way as to obtain a peripheral speed of application exceeding the theoretical feeding rate of the strip, able to be increased or decreased as needed to form turns with reduced or, respectively, enlarged cross section.

Abstract: A viscoelastic fluid molding material is injected into a tire tread cavity between the mold and an inflatable tread supporting body. The clearance distance between the mold and the inflatable tread supporting body is varied to increase the flow of the initial amount of fluid molding material into remote portions of the tire tread cavity and provide for the flow of the final amount of fluid molding material into gate portions while the tread supporting body is being deflected.Circumferentially spaced gates may be spaced from the centerplane of the mold and have runners extending toward the shoulders of the tread supporting body for increased flow of the initial amount of fluid molding material into remote shoulder portions of the tread cavity. Sealing rings at the side edges of the tread cavity prevent flow of fluid molding material into sidewall areas of side members of the mold.

Abstract: A process is provided for molding a tread on a vehicle tire body in which a tire body requiring a tread is supported in a mold which combines with the surface of the tire body to form a cavity conforming to the configuration and dimensions of the tread. The cavity is filled with a flowable vulcanizable elastomeric composition by injection at equally spaced points around the equatorial axis of the mold of measured volumes of material which will combine to fill the cavity and develop a low pressure in the mold cavity to insure flow of material until the cavity is completely filled. The invention also provides an injection molding apparatus having a mold which combines with a tire body supported therein to form a cavity corresponding to the configuration and dimensions of a tire tread. A series of equally spaced openings are provided around the equatorial axis of the mold for injection of molding composition and openings are provided around the sides of the mold cavity for the escape of air from the cavity as it is filled with composition.
