Zusammenfassung: | The method involves moving a substrate in a substrate treating system (1) by a transporting device (2) that is driven by a driving device (3) with a driving unit and a drawing unit (31). An empty strand of the drawing unit is tensioned during operation of the driving unit. A load end and a return strand of the drawing unit are clamped simultaneously, and a spring is arranged to generate clamping force applied by a clamping unit on the drawing unit, where the drawing unit is a toothed belt or a chain. An independent claim is also included for a drive device for driving a transporting device. |
