Abstract: An apparatus (1) for upending and transporting bottles (2) in continuous cycle is utilized especially in continuous cycle bottling plants using plastic bottles. The apparatus (1) comprises a horizontal axis (X) tubular body (70) having a guide (7) constituted by a slot (71) in a wall thereof, which slot (71) is of a breadth such as to permit passage of a neck (20) of a bottle (2). The slot (71) has an intermediate portion (71b) winding helically about the tubular body (70) by an angle equal to half a revolution. A bottle feed line (3) feeds the bottles (2) one at a time to the apparatus (1). Internally of the tubular body (70) a drive screw is rotatable about its axis (X) to engage the bottles (2) by the necks (20) thereof, urging them along the guide (7).
