Abstract:
A force transmission or transport device comprising a line of force transmitting elements (2), guide means (1) for guiding the force transmitting elements (2) along a predetermined course and at least one drive, wherein the at least one drive displaces force transmitting elements (2) actively in one location of the predetermined course and wherein force transmitting elements (2) displaced by the drive displace further elements by pulling or by pushing, wherein, for tensioning the line of force transmitting elements (2) in a section (5) of the predetermined course, a tensioning drive (6) acting on the elements (2) via a friction clutch is provided on one end of the section (5) and a further drive acting on the elements (2) substantially without slippage is provided on the other end of the section (5), wherein the driving speed (Vs) of the tensioning drive (6) is different from the driving speed (V) of the further drive (3).
