ABSTRACT:
Apparatus for ultraviolet drying and/or curing of freshly applied solvent-free ink on three-dimensional articles such as containers. Baskets for carrying the articles are swivelly mounted at spaced locations on an endless conveyor. The conveyor pathway has a bend or loop when viewed in elevation, the shape of which is determined by a drum or sprocket. A tubular ultraviolet lamp is arranged, preferably in the crook of the bend or loop, parallel to the axis of curvature of the bend or loop. The baskets are of perforate construction, preferably comprising wire strips in planes which intersect along lines parallel to their respective swivel axis. The lamp irradiates a predetermined sector of each passing article in the course of displacement over the bend or loop; shadows falling on the articles due to nonperforate portions of the baskets move continuously along the predetermined sector so that no spot on the predetermined sector is constantly obstructed from the ultraviolet radiation.
