Abstract
A drawing-device mechanism includes an endless drawing device and two wheels, around which the drawing device is partially looped. One wheel has a locally fixed axis of rotation and the other wheel is adjustable within an adjustment range. A drawing-device tensioner produces pretensioning. During an adjustment of the second wheel, with an increase in the center-to-center distance in a first case and with a reduction in the center-to-center distance in a second case, the drawing-device pretensioning remains approximately unchanged as a result of a reduction in the looping of the drawing device around the drawing-device tensioner in the first case and an increase in the looping of the drawing device around the drawing-device tensioner in the second case, absent any change in location of the drawing-device tensioner. A machine such as a sheet-processing rotary printing machine has the drawing-device mechanism.
