Vorrichtung und Verfahren für den Bahneinzug

To speed up the threading process and reduce manning levels, while the primary web from the printing press supply roll (not shown) is being threaded through the first components (eg successive printing stages) of the press, a secondary web 1' is fed from secondary roll 200 through splicing apparatus 300 and then through the remaining components (including web slitter 285) of the press. The primary web 1, having been threaded through the first components, is fed to nip 270,290 of the splicing apparatus and spliced to the secondary web 1', to which adhesive has been applied at 295. The secondary web is then severed at 280. To assist in the threading of the web ribbons through a folder downstream of slitter 285, while one ribbon 7.3 is being threaded, the others are wound on rolls 420, 421 to maintain a generally constant tension in these ribbons. When ribbon 7.3 has been threaded, ribbon 7.2 is cut and threaded, followed by ribbon 7.1.
