Abstract
To supply an arriving and delivered portion of a traveling web (1, 21, 31, 41, 81, 91, 101) to have the same side-orientation as the delivered portion, the web is passed about a first turning bar (2), then looped about a first deflection roller (3), and spanning the arriving portion of the web, about a second deflection roller (4) to be then turned again, selectively, by a second turning bar (5). Other web paths are possible, omitting the second deflection roller (4). Rather than using a single second deflection roller, smaller roller elements (FIG. 11: 16, 17) can be used, the second deflection roller, or the elements having effective diameters which are larger than the diameter of the first deflection roller. The turning bars and the deflection rollers are retained in an essentially rectangular frame, with the position of the turning bars adjustable along the sides of the frame and the position of the deflection rollers, likewise, preferably being longitudinally adjustable along the sides of the frame as well as height-adjustable perpendicular to the plane of the web traveling between the respective turning bars and deflection rollers.
