ABSTRACT:
Disclosed is an article transfer apparatus which comprises four driving sprockets, four free sprockets, and endless chains each having hooks arranged at regular intervals, and which carries an article held between front-end hooks and rear-end hooks. Driving sprockets for the rear-end hooks are rotated by a main motor, and driving sprockets for the front-end hooks are connected to the driving sprockets for the rear-end hooks by means of clutches.
