ABSTRACT:
An apparatus for producing a multi-colored closure member of a closure profile includes a die plate for receiving melted materials having different colors at a die plate input port and extruding the closure member at a die plate output port. The apparatus further includes an adaptor module, connected to the die plate input face, for channeling each of the melted materials to a selected section of the die plate input port which corresponds to a specific portion of the closure member. The adaptor module includes an input face with separate input ports for receiving each of the melted materials, and an output face with output ports configured substantially in a form of specific portions of the closure member. A configuration of channels connects the adaptor module input ports to the adaptor module output ports. Each selected section of the die plate input port is fed by a corresponding adaptor module output port.
