The invention provides a turning roller way at the cold end of a piece of plate glass; the turning roller way comprises a fan-shaped roller way (1); linear roller ways (2) are connected to both two ends of the fan-shaped roller way (1); the turning roller way is characterized in that a driving roller way (3) is just below the fan-shaped roller way (1); and the driving roller way (3) and the fan-shaped roller way (1) are in transmission fit through a synchronous belt. The turning roller way disclosed by the invention is simple in structure and low in manufacture cost; and in addition, higher coordination still can be provided by adopting single power control.
