摘要： A method and apparatus for automatically applying a flying splicing tape to a roll of sheet material (22). The roll of sheet material is defined by a width and includes an outer-most layer. With this in mind, the method includes lifting a portion (170) of the outer-most layer away from a remainder of the roll. The lifted portion (170) is then cut to form a leading edge that is otherwise spaced from a remainder of the wound roll (22). To this end, the cut is made at a defined spacial location along the outer-most layer such that the leading edge is radially aligned with a defined application line (172) relative to a circumference on the wound portion of the roll. In other words, when the outer-most portion is subsequently wound back onto the roll, the leading edge will be aligned with the defined application line (172). The splicing tape (102) is then applied to the wound portion of the roll at the defined application line (172), such that the splicing tape extends across at least a portion of the width of the roll. In one preferred embodiment, the splicing tape is applied in a straight fashion relative to an axis of the roll. Finally, the leading edge is adhered to an outer surface of the splicing tape. More particularly, the leading edge is positioned relative to the splicing tape such that the outer-most layer covers a first section of the splicing tape, whereas a second section of the splicing tape remains exposed. In another preferred embodiment, the applied splicing tape (102) is cut to form a trailing end that is substantially aligned with a side of the roll.
