Abstract: An inflation and deflation device for an inner tube and an inner tube provided with this device are described. The inner tube is elastically expandable for the introduction of fluid into its internal volume and can be housed in the space between tire and rim, which can be isolated from the external environment at atmospheric pressure. The device does not have elements for connecting the internal volume of the inner tube and the environment outside the wheel.

Abstract: Within the scope of the manufacturing of a tyre, a belt structure (2) is manufactured by means of strip-like segments (5) each comprising parallel strips incorporated in an elastomeric layer, sequentially laid in mutual circumferential approach relationship onto a toroidal support (3). During the laying of each segment (5), an angular rotation of the toroidal support (3) is caused about an axis of correction (Y-Y) radial to the axis of rotation (X-X) of the toroidal support itself, situated in substantially barycentric position relative to the segment (5) which is about to be laid. A perfect match is thereby assured of each strip-like segment (5) with the adjacent strip-like segments, even when the toroidal support (3) presents a crown area with curvilinear cross section profile.
