<p>In the present invention, a manufacturing process is provided in which a complete multi-component synthetic closure is achieved which incorporates printed indicia formed thereon, in a continuous, in-line manufacturing operation. In the preferred embodiment of the present invention, the core member of the synthetic closure is formed by a continuous extrusion process which enables the core to be manufactured as an elongated, continuous length of material. As the continuous elongated length of extruded material forming the central core is advanced from the extruder towards an outer skin forming station, the central core passes through a printing station for forming any desired indica on the outer surface of central core prior to the application of the outer skin layer.</p> |
