Abstract
An extrusion die apparatus for producing at least one plastic closure strip having profile and base portions, includes a die body having a die face, a profile channel defined in the die body and communicating with a profile die opening in the die face for extruding a profile portion, and a base channel defined in the die body and communicating with a base die opening in the face for extruding a base portion. The channels are adjacent to each other near the die openings and separated by a portion of the die body which terminates short of the face so that the extruded profile and base portions join together before exiting the die body.
