Two or more acceleration devices (8) are arranged at the top of the upper pulley wheels (3) and showing acceleration members protruding over and above the motion path of the carriers (2.1) and having a greater periphery speed than the speed of the carriers (2.1). The acceleration devices may consist of accelerating wheels (8). |
