Abstract
To avoid the necessity to readjust rollers (3; 6) located in advance of and downstream of a moving web (1) passing over a folding former (4; 4a, 4b) upon adjusting the folding former, the former is retained on a holding structure (11, 12, 14, 15) which is pivotable about a pivot point (S) located at the side of the former which is at the side of the web passing over the former, and opposite the side of the web facing the former, so that the pivot point is located at the side of the former which faces the web. Upon pivoting the former, the tip (5) will move only over a slightly distance vertically with respect to the axes of rotation of pull-off rollers (6), and the back edge (5) will change only slightly with respect to tangential position related to the web supply roller (3). The folding former may be constructed as a split former (4a, 4b) in which the split parts are individually adjustable to change the angle (.alpha.) of the folder parts.
