摘要： A drum for producing a tire casing blank comprises a support and sectors forming a circumferential face of the drum.
Each sector has a circumferential outer face having a contour of general trapezoidal form and is mounted so as to be movable relative to the support in a non-radial predetermined direction relative to an axis of rotation of the drum and intercepting this axis.-

摘要： The tread has a total axial width W and a wearable thickness PMU of material and has at least four grooves on each side of a midplane that divides the tread axially into two parts. The grooves divide the tread into a middle, intermediate and edge regions 6. The middle region has an axial width Lm of at least 30% and at most 60% of the total width W. The total volume void ratio when new is less than 17%, and the middle region has a volume void ratio that is less than half the total volume void ratio. The middle region comprises a plurality of transverse sipes opening into the grooves, and the sipes have depths at least equal to 75% of the depth of the grooves. The number of transverse sipes in the middle region is greater than the number of transverse sipes on each intermediate or edge region.

摘要： A system is provided for placement of noise attenuating foam along an inside surface of a tire to attenuate cavity noise. The system can be used with tires of various sizes and shapes such that different foam sizes may be utilized. The system provides for automating the process of foam placement in a manner that allows for consistent placement of the foam during e.g., tire manufacture.

摘要： An exemplary method of manufacture for a spoke (100) of a non-pneumatic wheel. The spoke can be manufactured with a reinforcement structure having reinforcement elements and one or more layers of material. The spoke can also be provided in various shapes and configurations. The spoke includes anchors (112, 114) that allow the spoke to be more readily incorporated into, or removed from, a non-pneumatic wheel. More particularly, the anchors also allow the spoke to be joined as one-piece with the non-pneumatic wheel or releasably connected on one or both ends with the non-pneumatic wheel.

摘要： A reinforced product, which can be used especially for reinforcing a finished rubber article, comprises one or more textile or metallic reinforcing thread(s), said thread(s) being covered with a sheath comprising a thermoplastic polymer composition, the sheathed thread(s) being themselves embedded in a rubber composition referred to as coating rubber, characterized in that this coating rubber is a composition based on at least one diene elastomer, a reinforcing filler, and a sulfur-based vulcanization system, which system comprises a vulcanization accelerator having a vulcanization initiation time, referred to as “t0”, of less than 3.5 minutes, preferably of less than or equal to 3 minutes.

摘要： The process includes a non-crosslinked self-sealing composition which is introduced into an extrusion means, the geometric and thermodynamic characteristics of which have been specially adapted. The speed and temperature conditions of the extrusion means are adjusted so that, at an application nozzle forming the outlet die of the extrusion means, the self-sealing composition is crosslinked. The application nozzle is brought close to the internal surface of the casing previously set in relative motion with respect to the application nozzle, and an extruded and crosslinked bead that has a given width and profile is deposited directly on the internal surface of the casing.

摘要： The disclosure relates to a selective laser sintering method of manufacturing a tread molding element, said tread molding element including at least a fine lamella adapted to mold a shallow sipe in a tire tread, the fine lamella having a length (L2). The fine lamella is sintered in a plurality of portions (p2) at different layers (N), in each layer (N) the laser beam sinters the portion (p2) of the fine lamella in only one passage in the length (L2) of the fine lamella without round-trip passage of the laser beam, the direction (D1) of this passage being the same at the different layers (N) for building the different portions (p2) of the fine lamella. The thickness (w) of the fine lamella is smaller than 0.2 mm, and the height (h) of the fine lamella is smaller than or equal to 2 mm.

摘要： Each of at least two layers of a carcass reinforcement has a breaking force per unit width higher than 2250 daN/dm. The minimum strength per unit width, measured for an elongation of less than 10%, of a second layer of carcass reinforcement is strictly greater than a value equal to 20% of the minimum strength per unit width, measured for an elongation of less than 10%, of a first layer of carcass reinforcement. The reinforcing elements of the two layers of carcass reinforcement have a thread count of less than 750 tex. The elongation of the reinforcing elements of the second layer of carcass reinforcement is greater than 4% under a force of 20 daN, and the secant elastic modulus values under tension at 10% elongation, Mt, Mj, satisfy the relationship Mt/Mj≥1.
