PURPOSE: To rapidly and surely cure a can end using a compact oven by providing a ringlike structure having the diameter much larger than the sectional diameter of an article, an article receiving means provided on its outer circumference, and a magnet means to maintain the article in a separated and projecting condition from each other in an erected condition outwardly in the radial direction of the outer circumference.

CONSTITUTION: An article receiving means 40 is fitted to a rotary conveyor 10, and an article storage part 42 formed in a shape to surround and receive a part of a can end 15 is formed on an outer circumference of the rotary conveyor 10. A magnet means or device 44 is also fitted to an outer circumference of the rotary conveyor 10 adjacent to the article storage part 42, and attracts the can end into the article storage part 42 through the magnetism, and maintains the articles separate from each other in an outwardly projecting condition in the radial direction from the outer circumference of the rotary conveyor 10, and with the can end in an erected condition or in an upright condition at the circumferential edge. The can end is easily cured while carried from a carry-in conveyor 14b to a carry-out conveyor 16 in an over 12 by the can end rotary conveyor 10.
