摘要： A method for ascertaining the deformation of a tire comprises: fastening a sensor to the tire so as to generate an accelerometric signal in the direction normal to the crown; acquiring (201) a temporal wheel-turn signal SigTDR (101) comprising the amplitude of the acceleration while rolling; determining a reference speed Wreference (202) associated with a portion of the wheel-turn signal SigTDR; normalizing (203) the portion of the wheel-turn signal SigTDR by a variable which is a function F proportional to the square of Wreference; angularly resampling (204) the portion of the wheel-turn signal SigTDR; defining an energy density S (205) from the angularly resampled normalized wheel-turn signal SigTdR using a threshold A; and identifying the deformation of the tire Def % (206) as a function G of the energy density S.

摘要： A method for manufacturing a bonded reinforcing textile filamentary element (48) comprising a core and a layer of strands is disclosed. The textile filamentary element in the natural state is assembled. A textile filamentary element in the natural state or pre-bonded textile filamentary element is obtained. The filamentary element in the natural state or pre-bonded filamentary element is coated with an external layer of at least one heat-crosslinkable adhesive composition. The filamentary element in the natural state or pre-bonded filamentary element that is coated with the external layer is thermally treated so as to crosslink the adhesive composition in order to obtain the bonded filamentary element (48). The steps of coating with and of thermally treating the external layer of the filamentary element in the natural state or pre-bonded filamentary element are carried out such that, for an elongation equal to 30% of the elongation at break of the filamentary element in the natural state, the tangent modulus of the bonded reinforcing textile filamentary element (48) is increased compared with the tangent modulus of the filamentary element in the natural state.

摘要： A method for supplying green tire manufacturing machines (14) with elastomeric products (12) by means of a supply facility (10) comprising a loading member (30) and at least one transfer member (34) comprising an unwinder (36) is disclosed. The supply facility comprises a preparation station (32), said preparation station comprising a manipulator arm (70), and at least one motor (53), the preparation station and the unwinder being distinct from the green tire manufacturing machine. The method comprises the following successive operations: loading the reel onto the unwinder; positioning the end of the product wound on the réel; arranging the end of the product in such a way that it is laid on a dispenser of the unwinder; and transferring the reel from the preparation station to the green tire manufacturing machine.

摘要： A sail-propulsion element comprises a mast (3), an inflatable sail (1) consisting essentially of two substantially fluidtight adjacent surfaces (4a, 4b) joined together along their periphery, thus forming between them at least one cavity closed around the mast (3), at least one air conduit positioned between the inside and the outside of the cavity, at least one means for injecting air into said cavity, the sail once inflated having a profile that remains permanently symmetrical, irrespective of the movement of said propulsion element, or of the direction or strength of the wind, a headboard, and a sail. The sail comprises a plurality of cells (5) in the direction of the span of the sail, each cell (5) extending from the leading edge (6) to the trailing edge (7), said cells (5) being spaced apart by ribs made of a first soft material.

摘要： A mixing and extrusion machine (10) for the manufacture of rubber mixtures includes a mixer with a converging conical twin-screw (12) with a fixed frame (14) that supports sleeves (16). Two screws (18), being mounted at an angle, are mounted in the mixer (12) in such a way as to move in translational movement between an opening (22) arranged upstream and an outlet (25) arranged downstream of the sleeves. The screws are mounted in the sleeves with removable doors including sliding shutters (40) installed relative to the outlet (25). The sliding shutters move linearly between a closed position, in which the sliding shutters prevent the mixer from discharging the mixture, and an open position, in which the sliding shutters prevent discharge of the mixture through the sides of two counter-rotating rollers (32) of a roller nose type system located just downstream of the outlet.

摘要： The manipulator device includes a pedestal and a carrying mechanism which carries a platform and which forms an articulated triangle comprising: a first arm borne by a first carriage with a first pivot link whose axis forms a first vertex of the triangle, a second arm borne by a second carriage with a second pivot link whose axis forms a second vertex of the triangle, a seat situated at the intersection of the first arm and of the second arm, which forms a third pivot link whose axis is parallel to the first pivot axis and the second pivot axis and forms a third vertex of the triangle. A module is provided for servocontrolling the translational movements of the first carriage and the second carriage with respect to the pedestal. A yaw orientation interface comprises a fourth pivot link, by which the platform is articulated on the seat, both relative to the first arm and relative to the second arm, about a fourth pivot axis which is coaxial to the third pivot axis.

摘要： The method comprises a braiding step during which a braiding wire is wound in helical turns about, and along, a generatrix line which is closed in a ring about a main axis, so as to form a bead wire element called “braided torus” within which the braid wire has, on the one hand, a winding section which corresponds to the helical turns and which occupies a braid volume, and, on the other hand, in an extension of said winding section, a surplus length of braid wire called “excess section”. After the braiding step, there is a folding step during which the excess section is plastically deformed by folding, preferably by means of a punch and an anvil, so as to form an elbow which makes the excess section diverge with respect to the helical turns and makes said excess section protrude at least partly with respect to the braid volume.
