<p>In the present invention, a manufacturing process is provided in which a complete multi-component synthetic closure (20) is achieved which incorporates printed indicia (30) formed thereon, in a continuous, inline manufacturing operation. In the preferred embodiment of the present invention, the core member (22) of the synthetic closure (20) is formed by a continuous extrusion process which enables the core (22) to be manufactured as an elongated, continuous length of material. As the continuous elongated length of extruded material forming the central core (22) is advanced from the extruder towards an outer skin (24) forming station, the central core (22) passes through a printing station for forming any desired indica(30) on the outer surface of central core (22) prior to the application of the outer skin layer (24).</p> |
