A pneumatic radial ply tire () comprises a tread (), a belt structure (), and a carcass (). The carcass () has a radial ply () and two bead sections (A,B). Each bead section (A,B) has a bead () and a component apex () with a inner apex (A), a middle apex (B) and an outer apex (C).

The disclosed roller switch has a roller, a flag arm, and a photoelectric detector. The roller is connected to the flag arm and vertical movement of the roller causes the flag arm to move. The movement of the flag arm causes the photoelectric detector to send a signal. The signal may be used to measure the length of a material passing under the roller. The inventive roller switch has a pair of flag arms, and the roller is mounted on a shaft extending between the pair of flag arms. By providing a pair of flag arms connected by the roller, the roller switch is more robust and durable. The roller switch is also capable of pivoting across a conveyor belt.

A conveyor assembly and method for conveying and storing a strip material in a conveyor system that is subject to changes in length of the strip material due to intermittent operation includes an upper conveyor (,), an adjustable substantially horizontal center conveyor (,) for receiving the strip material (,) from the upper conveyor, and a lower conveyor (,) for receiving the associated strip material from the center conveyor. A computer (,) controls the movement and rotation of the center conveyor, and loop detecting apparatus on the center conveyor may also detect a loop (,) in the strip material carried by the center conveyor and thereby detecting changes in length of the strip material not predetermined by the computer. A servomechanism (,) activated by signals from the computer or the loop detecting apparatus moves the center conveyor in a substantially horizontal direction.

An extruder for extruding an associated material includes an extruder housing that has a feed section, a center section that includes a throttle section, and an outlet section with an extruder screw disposed in the extruder housing. The extruder also includes a throttle at the throttle section. The throttle has a plurality of pins that extend radially into the housing. The pins are adjusted by a cam extending around the extruder housing. The cam has an inner wall that has a plurality of cam surfaces engageable by pins. The radius of each of the cam surfaces gradually decreases from a maximum radius to a minimum radius distance. The pins have springs that urge the pins radially outward to contact the inner wall of the cam. The cam is rotated by a piston and cylinder assembly. The extruder further includes sensors for temperature, gauge, weight, and other properties of the material. The extruder also has a control apparatus for controlling the speed of the extruder and the throttle based upon any combination of temperature, gauge, weight, and production requirements while the extruder is in operation.
