Abstract
A device for accurately setting a roller gap of a folding device of a rotary web-fed press uses a rotatable threaded spindle with contrarotating threads at both of its ends. A drivable differential screw gear mechanism is associated with each threaded spindle end and operates to pivot two-armed levers that support the folding rollers to thus vary the roller gap.
