Abstract
The invention is directed to a crosshead die for the extrusion of a profile, such as a uniform ply coat for a tire. The crosshead die is used with an extruder, and includes a body. An inlet is formed in the body, and is in fluid communication with the extruder. An outlet and a flow channel are also formed in the body. The flow channel extends between the inlet and the outlet, and is bounded by an upper wall, a lower wall, a first side wall, and a second side wall. The flow channel is formed with a bend and a cross section that includes a trapezoidal shape to align the flow of elastomer with the center of the flow channel.
