ABSTRACT:
An apparatus and method of splicing a continuously moving web cuts and transfers the web to a new core for rewinding with a no-fold-back and wrinkle-free splice. The web is fed through a first nip point formed by a first introducer roll and a second cushioned anvil roll, and the web is through a second nip point formed by the second cushioned anvil roll and the new core. An electrostatic charging bar positioned downstream from the first nip point emits an electrostatic charge onto the web to temporarily adhere it to the second cushioned anvil roll. A rotatable cutting knife which is cooperatively engageable with the cushioned anvil roll cuts the web at a point downstream from the electrostatic charging bar but upstream from the new core thereby forming a tail and a new leading edge. The tail continues to be rewound about a finished roll. Because the new leading edge of the web has been electrostatically charged it remains stuck to the cushioned anvil roll until it reaches the new core. At that point, adhesive on the new core peels the new leading edge of the web off of the cushioned anvil roll and affixes it onto the new core. The web is thereafter rewound about the new core.
