Abstract: A pneumatic tire for use on aircraft has a tread, a crown reinforcement, and a radial carcass reinforcement having at least one axially inner ply of textile cords wound around a pair of bead cores, at least one axially inner ply being wound around the bead core in each bead from inside to the outside forming outside turn-ups and at least one axially outer ply of textile cords extending from bead to bead along the turn-ups of the at least one axially inner ply. The at least one axially inner ply or at least one axially outer ply has merged cords having a percent elongation at break of 12% to less than 20% and a break strength greater than 1050 N with a linear density of greater than 9,000 dtex. Merged cord reinforcement is preferably used in the ply layers or strips of the crown reinforcement as well.

Abstract: This invention disclosed a pneumatic tire for use on aircrafts having a tread, a crown reinforcement, and a radial carcass reinforcement. The carcass reinforcement has at least one axially inner ply of textile cord wound around a pair of bead cores, at least one axially inner ply being wound around the bead core in each bead from inside to the outside forming outside turn-ups and at least one axially outer ply of textile cords extending from bead to bead along the turn-ups of the at least one axially inner ply. Each bead has an elastomeric apex filler. The at least one axially inner ply or at least one axially outer ply has merged cords having a percent elongation at break of 12% to less than 20% and a break strength greater than 1050 N with a linear density of greater than 9,000 dtex. The preferred cord has fibers of polyamide and nylon. The cord fiber of polyamide is an aromatic polyamide 3300/2 construction. The cord fiber of nylon is a 1880/1 nylon construction. The preferred cord construction is 6.

Abstract: A composite cable is disclosed suitable for use as a reinforcement in an aircraft tire. The cable is formed of an aramid yarn and a nylon yarn cabled together, wherein the aramid yarn has a linear density in the range of about 220 to about 3300 dtex, and the nylon yarn has a linear density in the range of about 220 to about 2100 dtex.

Abstract: Disclosed is a tire having at least one reinforcing ply in the carcass, belt, or bead region of the tire. The reinforcing ply is comprised of a blended fiber cord. The cords, in combination with a preferred cure temperature adhesive, achieve a high degree of thermal stability allowing for the use of such cords in various reinforcing plies for a pneumatic tire and for preferred use for such cords in areas of the tire subject to high temperatures either in curing or performance.

Abstract: An apparatus (10) for welding materials has a flat anvil (12) having a width of at least two inches and a length of at least eighteen inches. A welding apparatus (14) having at least one welding head (22) is mounted on a rail (16) which is parallel to said anvil (12). The apparatus (10) may be mobile. In an illustrated embodiment, welding apparatus (14) is an ultrasonic welding unit, and apparatus (10) is used to weld thermoset materials. As illustrated, the method is used to weld thermoset plastic monofilament fabric (34) to provide a continuous method of treating the monofilament fabric (34).

Abstract: An apparatus for welding monofilaments at a loom makes possible a method for a continuous process for weaving monofilaments into fabric. The apparatus comprises a stand (15) on which is mounted welding apparatus (16) and a filament alignment block (20). In the method, a monofilament (30a) in the loom is welded to the leading end of a monofilament (30) on a new spool of monofilament. By welding new monofilament to monofilament in the loom, restringing of the loom is avoided.
