摘要： The present invention is directed towards a pneumatic radial tire. The tire is comprised of a reinforcing belt structure wherein the belt plies are divided into at least three segments. The reinforcing cords in each segment of a ply are oriented in the same inclination direction. By maintaining the same cord inclination in the segments, dividing the belt ply into segments creates hinge points for the belt ply, reducing the stiffness of the ply across the width of the tread from the centerline of the tire to the tread edges. If the belt structure has more than one reinforcing ply, the segments of the adjacent plies are staggered by a distance at greater than the radial height between the radially inner side of the adjacent belt plies.

摘要： A pneumatic tire includes a carcass reinforced by a carcass ply, at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire, and at least one overlay ply disposed radially outward of the belt ply in the crown portion of the pneumatic tire. The overlay ply includes at least one composite cord having at least one first core yarn with at least one second outer metallic filament wrapped around the first core yarn such that the first core yarn has a modulus less than a modulus of the second outer metallic filament. The first core yarn has a diameter in the range between 0.012-0.035 inches and a twist in the range between 5-15 TPI. The second outer metallic filament is twisted about the first core yarn between 3-14 TPI.

摘要： A wire drawing machine includes a frame; at least one die operatively supported by the frame; at least one drawing block rotatably supported by the frame for use in drawing wire through the die; and, a motor for use in providing power. A belt system connects the motor to the drawing block so that the drawing block can be rotated. To adjust the speed and torque of the drawing block, the belt is removed and one sprocket is replaced with a second sprocket.

摘要： Steel wire is drawn from an initial diameter to a desired final or intermediate diameter by the use of a non-linear tapered draft. During the non-linear tapered draft, the wire is drawn through a series of successive dies, reducing the wire diameter to a desired diameter, wherein the drawing strain at each successive die is gradually reduced. The drawing strain is based upon the actual strength of the steel at each die. The wire may also be subjected to a skin pass, reducing the wire by a diameter by less than 4%, following reduction of the wire to either the final or the intermediate diameter.
