Abstract: An accumulation conveyor system for transporting piece goods along a predetermined path is disclosed. The system comprises a passively transporting element and an actively transporting element. The passively transporting element comprises a series of idle rollers arranged substantially in parallel with each other and form an elongated and substantially continuous and substantially equiplanar path for supporting the goods. An endless conveyor belt is provided for circulating around at least two guide rolls and forms an upper train for motion in a first direction and a lower train for motion in a second direction opposite to said first direction. The passively transporting element and the actively transporting element cooperate to convey the goods along a predetermined path and provides for smooth accumulation of the goods when movement of the goods closest to the delivery end is arrested.
