摘要： Annular guide grooves and rotating ratchet wheels are provided, and feed claws formed in said ratchet wheels moves along said annular guide groove in a circumferential direction. Also, first and second supply conveyers are provided, articles are arranged in the same direction and transferred on these supply conveyers, and sent into said annular guide grooves by supply mechanisms. Said first supply conveyer is arranged to be directed in a direction of a contact line of said annular guide grooves and in the same direction as the moving direction of said feed claws. Said second supply conveyer is arranged to be directed in a direction of a contact line of said annular guide grooves and in the opposite direction to the moving direction of said feed claws. The back portions of said articles sent from said first supply conveyer are pressed by said feed claws, and the front portions thereof are moved toward the advancing direction. The front portions of said articles sent from said second supply conveyer are pressed by said feed claws, and said front portions are moved backward the advancing direction. The articles moved in said guide grooves are transferred on an exhaust conveyer. Therefore, the articles are arranged in a state that the directions of the articles are alternately opposed to each other.
