Abstract

To prepare an initial portion (41) on a replacement roll (4) of a substrate web, for example a printing paper web, for flying pasting, the new roll (4) is rotatably supported in apredetermined position. An adhesive application and cutter structure (5) is then placed in operative association with the roll. An initial portion (41) of the web is rolled off from the new roll, positioned on the support plate, and, in one operating step, an end, which may be jagged, is cut off and, inwardly of the cut edge (42), a perforating or tear-off line (43) is formed, to leave, between the cut edge and the tear-off line, a tear-off section (44). The web can then be repositioned on the plate (6) and a connecting adhesive (19) is applied to the upper side of the web, for subsequent flying pasting against a moving expiring web, for example, as well as a holding adhesive, applied in the inside of the tear-off section (44), so that the end portion (41) is securely attached to the roll. Preferably, the cutter and perforating blades are located on a single support block; and the adhesive applicators, likewise, are retained on a common support structure, which may be coupled with the blade support structu…
