ABSTRACT:
A tensioning device (32) for tensioning at least two, substantially length-invariant belts (18, 24) includes a first belt (18) guided about a first axis (A), which repeatedly guides an adjusting movement in an adjustment direction substantially orthogonal to the axial direction of the first axis (A). In addition, the first belt (18) and a second belt (24) are guided about a common second axis (B), whereby the tensioning directions (V18, V24) of the first belt (18) and of the second belt (24) in a region of the second axis (B) forms a varying angle of between 0° and 180°. The second axis (B) is associated with a spring unit (40), which prestresses in the sense of the tensioning of the first belt (18) and the second belt (24) and which, upon an adjusting movement of the first axis (A), permits a compensating movement of the second axis (B) from the plane covered by the axial direction of the second axis (B) with the tensioning directions (V18, V24) of the first belt (18) and of the second belt (24), respectively, before initiating of the adjusting movement.
