PROBLEM TO BE SOLVED: To supply an article thrown at random pitches from a pre-process to a next process at predetermined pitches using a single endless conveyor. SOLUTION: Positions of two sprockets 2a, 2c arranged at a pair of diagonal corners around which an endless chain 3 is wound and which forms a circumference path of quadrangular shape are fixed, and the corners to which the sprockets 2a and 2c are arranged respectively serve as throwing-in end 7 and discharge end 8. Sprockets 2b and 2d arranged to other corners are respectively coupled to the sprockets 2a and 2c through rotating arms 12a and 12b of equal length, and each of the rotating arms 12a and 12b are reversely rotated at an equal angel, to thereby increase or decrease a length of a return path returning a carrier 5 which receives thrown stockings from the discharge end 8 to the throwing-in end 7 in accordance with a throwing-in pitch at the throwing-in end 7. Accordingly, the stockings thrown in at the random pitches at the throwing-in end 7 are supplied to the discharge end 8 at the predetermined pitches. COPYRIGHT: (C)2004,JPO
