Devices, methods, and systems for splicing a trailing edge of an outgoing roll with a leading edge of a replacement roll with a lapless butt splice on-the-fly during converting and printing production. A first strip of adhesive tape may be placed partially under the leading edge, such that a portion of the adhesive tape remains exposed beyond the leading edge. The replacement roll may be accelerated to match the speed of the outgoing web's movement, a trailing edge of the outgoing web may be cut free from the outgoing roll, and the trailing edge of the outgoing roll may be positioned over the exposed portion of the adhesive tape. A second strip of adhesive tape may be applied over the leading edge and trailing edge using a splicer roller timed to apply the tape when the edges pass proximate to the splicer roller.

Adhesive tape for the on-the-fly roll changeover of flat web material wound up into rolls, comprising a carrier layer having a first surface and a second surface, a first layer of adhesive on the side of the first surface over at least part of the area, and a second layer of adhesive on one or more areas of the second surface, wherein the adhesive tape has regions suitable for areal splitting, at least those areal regions of the second surface on which the second layer of adhesive is provided being surface coated, the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of adhesion of the surface coating to the carrier layer, and/or the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of cohesion within the surface coating.
