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.

A corrugated cardboard plant has a corrugated cardboard production assembly having at least one device for producing at least one corrugated cardboard web which is laminated on one side, and a connecting device for generating a corrugated cardboard web which his laminated on both sides and which comprises the at least one corrugated cardboard web which is laminated on one side. The corrugated cardboard plant furthermore has a printed web/lamination web production assembly which has a printing device for printing a printed web, a printed web storage device, and a lamination web unwinding device for unwinding a lamination web. The corrugated cardboard plant moreover has a coupling/uncoupling assembly having a coupling device for coupling the printing device to the corrugated cardboard production assembly while using the printed web as the lamination web in the corrugated cardboard production assembly, and/or an uncoupling device for uncoupling the printing device from the corrugated cardboard production assembly while using the lamination web in the corrugated cardboard production assembly.

An apparatus, and a related method, for unwinding reels and for joining a ply between two reels including a first unwinder adapted to unwind a first reel, a second unwinder adapted to unwind a second reel, a joining device adapted to join a first ply belonging to the first reel with a second ply belonging to the second reel, the joining device including a first pulling bar is able to pull a flap of the first ply along a joining path with the second ply, a second pulling bar is adapted to pull a flap of the second ply along a joining path with the first ply, joining means configured to join, in a joining point along the joining path, the flap of the first ply with the second ply or the flap of the second ply with the first ply, first cutting means configured to cut the first ply or the second ply upstream of the joining point where the joint is performed between the first ply and the second ply, and second cutting means configured to cut the flap of the first ply or the flap of the second ply downstream of the joining point.

An apparatus for splicing comprises a first web support surface configured to support a traveling web thereon and a second web support surface configured to support a replacement web thereon. The first traveling web travels in a machine direction. The splicing assembly also comprises a first web sensor and a web joiner. A controller is configured to determine, via the first web sensor, a position of a trailing end of the traveling web and to, in response to determining the position of the trailing end, cause a leading end of the replacement web to be positioned adjacently to the trailing end. The computer is also configured to control the web joiner to create a joint coupling the trailing end to the leading end.

The present invention concerns a method for joining the ply of a reel of paper in depletion with the initial flap of a new reel, as well as an apparatus adapted for carrying out such a method. Thanks to the method according to the present invention, and to the apparatus suitable for carrying it out, the joining of the reels takes place without using gluing means, like for example the double-sided tape used in known methods, avoiding the relative drawbacks, the adhesion between the plies of the reels to be joined taking place by electrostatic attraction.

An electrode connection cause determination system includes a position measuring instrument. The position measuring instrument is configured to, when an electrode moves between an unwinder and a rewinder in a roll-to-roll state, acquire coordinate value data based on a longitudinal position of the electrode determined according to a rotation amount of the rewinder. The system includes a signal generator configured to generate a connection advance notice signal if the electrode includes a connecting portion corresponding to a cause event, a seam detector configured to detect a seam attached onto the electrode after the connection advance notice signal is generated, and a determination unit configured to, when the seam is detected within a predetermined distance from a first coordinate value of the electrode after the connection advance notice signal is generated, determine that a connection cause of an electrode connection by the seam corresponds to the cause event.
