ABSTRACT:
Apparatus for ultraviolet light curing by photopolymerization of ultraviolet curable ink printings on the external surfaces of tubular articles, such as plastic, glass or metal bottles, jars or other containers. The tubular articles are placed in an upright position on a rotating disc in a housing which carries them through an ultraviolet radiation field emitted by an appropriate ultraviolet source, and reflected by specially shaped reflectors to provide intense ultraviolet radiation in the entire housing and thereby eliminating the need to stop and spin the articles in front of the ultraviolet source to achieve complete curing around the entire article. An elongated guide is mounted to extend partially across the upper surface of the table, and as the table rotates it serves to move the articles against the guide which causes them to rotate about their respective vertical axes so that the entire peripheral surface of each tubular article is exposed to the ultraviolet radiation. The table then carries the articles to an appropriate unloading station.
