Abstract: A rotary frame construction for web transport control devices, includes a carrier frame and a rotary frame in parallel therewith and carrying input and output rollers for a web and pivotably mounted on the carrier frame about a rotation center defined by control surfaces of one frame, the control surfaces scanned by cam followers on the other frame, the frames held in parallel alignment by support rollers on one frame and run surfaces on the other frame, the frames pivotally connected with one another by a drive system, the control surfaces constituted by three control curves formed at outer edges of a cam plate rigidly held on one frame, two of the control curves located on one side of the cam plate and the third on the opposite side of the cam plate, and the other frame has three cam followers respectively associated with one of the control curves.

Abstract: A web transport control device having a plurality of rotary frame units each of which includes a carrier frame, a rotary frame parallel thereto and carrying an input roller and an output roller for a material web, and pivotably supported on the carrier frame, a web guiding system arranged such that each of the material webs is fed to one of the input rollers, deflected thereat and then deflected again at the output roller, wherein the rotary frame units are nested one in the other such that web sections of the webs that extend between respective input and output rollers are parallel to one another and the spacing between two neighboring web sections is not larger than the sum of diameters of the input and output rollers, and the input rollers are offset relative to one another in the direction parallel to the web sections.
