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