Abstract
An ultraviolet light curing apparatus for curing inks and other coatings on cans and similar containers in which the cans are passed by a conveyor about a source of ultraviolet light and, as the cans rotate about the source, they receive virtually all the light rays from the ultraviolet light source by means of the ultraviolet light being reflected by reflectors rotating circumferentially around the light source.
Claims7
A method for continuously curing ultra-violet-curable coated articles comprising:
- (a) passing said articles about an ultraviolet light source;
- (b) rotating the surfaces of the articles relative to the light source as the articles pass thereabout
- (c) rotating reflector means about the light source in substantially synchronous relation to the articles, thereby focusing the light continuously on the surfaces of the articles during passage thereof about the light source.
Apparatus for continuously curing ultra-violet light curable coated articles comprising:
- (a) A fixed source of ultra-violet light;
- (b) Conveyor means for conveying the articles about the light;
- (c) Means for rotating the surfaces of the articles relative to the light source as the articles pass thereabout;
- (d) reflector means disposed between the light source and the articles for focusing the light on the surfaces of the articles during the passage thereof about the light source;
- (e) means for rotating the reflector means around the light source in substantial synchronism with the rotation of the articles about such source.
