Abstract (en)
The web leading edge (E) of a paper roll (R2) for a rotary press or the like is held and prevented from raveling by three or more pieces of strong adhesive tape (Ta) during handling and loading onto a paper feed machine of the printing press. On the paper feed machine, perforated tear lines (123) are formed across the tape pieces (Ta) by a device comprising a rotary perforating wheel (162), a mechanism for moving the wheel from one end to the other of the roll (R2) and also moving it against and away from all of the tape pieces (Ta), and a tape detecting device (BS) and a controller (165) for automatically operating the mechanism. The tape pieces (Ta) can then be easily torn to release the web leading edge (E) immediately prior to web splicing.
