Abstract: A method and apparatus for automatically applying a flying splicing tape to a roll of sheet material. 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 of the outer-most layer away from a remainder of the roll.

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 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. The splicing tape is then applied to the wound portion of the roll at the defined application line, such that the splicing tape extends across at least a portion of the width of the roll.
