PURPOSE:To make suction force act timely on a part on the opposite side by connecting a sucking chamber provided on the side of an endless timing belt, to said part on the opposite side across said belt through through holes on said belt. CONSTITUTION:An endless timing belt 3 is put around two front and rear wheels 1 having teeth 3 on their outer peripheries, and corrugated grooves 4 are meshed with the teeth 2 of the wheel 1. Through holes 5 are formed on the belt 3, and connection is made between a sucking chamber 6 provided on one side of the belt 3 and a part on its opposite side across the belt, through the holes 5. When a basket A having many sucking holes (a) is used on said part on the opposite side, for example, the inside of the basket A is connected to the inside of the sucking chamber 6 through a slip type opening 6b of the chamber 6 and the hole 6 only when the basket A passes on the side of the chamber 6, causing the suction force in the chamber 6 to act on the sucking holes (a) of the basket A and, further, to act on an article B on the basket A. |
