Abstract: Cup-shaped articles made of thermoplastic material which have their outer surfaces printed or coated with a heat-sensitive material are dried in apparatus wherein a feeding device conveys the printed or coated articles to the lower end of a vertical run of an endless belt in a drying device, so that the articles are placed in inverted position on the belt to be held on the belt by suction exerted through the belt, the articles being so handled in the feeding device that they enter the drying device in proper orientation and in alignment with and at the same speed as the belt. The feeding device may be an arcuate channel with pneumatic pressure advance of the articles, or may be a porous belt running over a suction chamber.
