Abstract: A device for inflating and deflating a flexible container which is elastically expandable for introduction of pressurized fluid into an internal volume of the container is described. The device is housed inside a cavity isolable from a surrounding environment, the device being inserted in a wall of the container. Pressurized fluid can flow from the surrounding environment into the cavity and from the cavity out to the surrounding environment. The device does not have elements for connecting the internal volume of the container and the surrounding environment.

Abstract: A method of foreseeing and controlling wearing in the tread of a tire based on the use of cuts of a limited depth (in the order of tenth parts of one millimeter) formed on the external surface of the tread, in the thickness of the elastomeric material. The cut is preferably made by a laser beam. Rotation of the tire on a road or on any other friction surface enables both the uneven wearing of the tread, highlighted by localized spots devoid of cuts, to be quickly verified by inspecting the maintenance state of said cuts, and the wear rate of the tread, which can be drawn from calculation of the time elapsing between the disappearance of two groups of cuts of different depth.

Abstract: A belt for supporting strips of deformable material includes a flexible central band. One or more strips are placed onto the band. Variable-configuration air chambers are arranged along edges of the band. The air chambers, when inflated, may have upper and lower surfaces that are substantially flat and substantially parallel to the band. An apparatus for using the belt includes a storage coil, a take-up winding, and first, second, and third devices. A first part of the belt is wound onto a reel of the storage coil with a first tension. A second part of the belt is wound onto a beam of the take-up winding with a second tension greater than the first tension. The first devices vary the first and second tension, the second devices keep the air chambers in the first part of the belt inflated, and the third devices rotate the reel and beam.

Abstract: The invention relates to an apparatus (1) for testing tire compounds, which comprises a road drum (3) and a specimen (5), rotating about respective parallel axes (X, Y) and being in rolling contact with each other. The specimen (5) of rubber to be analysed is mounted at the end of a spindle operated by a motor (6): advantageously the spindle is housed inside a closed casing (63) so as not to be exposed to water or other agents during the tests. This results in an apparatus wherein the spindle driving the specimen may be supported by non-sealed and hence low-friction bearings, thereby not altering the results of the tests carried out.

Abstract: In a tire for motor-vehicles, an auxiliary support element (9) is interposed between a carcass ply (3) and a belt structure (6). The support element is employed during the manufacturing step of the belt structure (6) in order to stably retain, on the sectors of a comb drum (10), coils (7a) consecutively formed by winding of an inextensible cord (7) therearound. The auxiliary support element (9) is made in the form of an elastomeric sheet containing short aramid fibers in an amount included between 1 and 10 parts by weight per 100 parts of elastomeric material, to increase the stretchability of said element without impairing its adhesiveness. The introduction of the short aramid fibers in the blend enables the thickness of the auxiliary support element (9) to be reduced to about 0.075 mm.

Abstract: The invention relates to a breaker belt structure to be used in pneumatic tires, in particular in those of the radial carcass type. The structure comprises a radially outer strip of circumferentially arranged cords (61), preferably but not exclusively made of textile material, as polyamide or aromatic polyamide, and two felted layers (62), (63), situated in a radially inner position, which comprise an elastomeric or plastomeric supporting material and a reinforcing filler of aramide pulp oriented along a preferred direction which is inclined with respect to the circumferential direction, the preferred directions of orientation in the two felted layers being preferably inclined symmetrically to each other at an angle of 45.degree. with respect to said circumferential direction.
