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.

In a method for packaging products, the products are packaged with a packaging material on a packaging line. The packaging material is first of all drawn off a first packaging-material reel and fed to the packaging line. When the first packaging-material reel has been at least partially used up, an initial portion of a second packaging-material reel is made to overlap with a packaging-material portion already drawn off the first packaging-material reel and is joined to the latter packaging-material portion. After the two packaging-material portions have been joined together, the packaging material is drawn off from the second packaging-material reel and fed to the packaging line. The two above-mentioned packaging-material portions are joined together by a stamping operator of a stamping device. There is also described a packaging installation for carrying out the method.

Splicing method and unit for a packaging machine, whereby a first film is spliced to a second film which is a spare film. The splicing is performed by means of an adhesive element with two opposing adhesive surfaces, one for each film, and a longitudinal adhering element. First an adhesive surface is adhered to the adhering element and said adhering element moves so that the other adhesive surface comes into contact with the second film and adheres to it. Then the adhering element is separated from said second film, the adhesive element being adhered to said second film, and the first film is caused to come into contact with said adhesive element already adhered to the second film.

A device for joining webs with self-adhesive labels comprises a web retaining element (18) for, in use, selectively retaining the starting end (16) of a new web (13) at an operating zone (15) positioned along a feed path of a first web being used and a pressure element (26) positioned on the opposite side of the first web; at least one of either the retaining element (18) or the pressure element (26) being movable relative to the other, between a non-operating position in which they are at a distance from each other and an operating position in which the pressure element (26) presses the first web (10) onto an adhesive element fixed to the new web (13); it also comprises a cutting (27) movable between a non-interference position and a cutting position, movement means for moving the cutting element (27) from the non-interference position to the cutting position, and controlled feeding means for the first web (10) which are operatively associated with the movement means for causing controlled feeding of the first web (10) in the operating zone (15) during movement of the cutting element (27) towards the cutting position. A method for joining implemented by the device is also claimed.

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.

A method for unwinding includes loading a first reel of web material into a first unwind position where the web is unwound. A splicing unit is then moved in the machine direction toward the first unwind position until there is sufficient space to allow a further reel to be loaded into a second unwind position where the web from the second reel is unwound once loaded. Then, the web from the first reel is spliced to the second reel, and the web of the first reel is thereafter cut. The process continues in the opposite direction after removing the first reel from the first unwind position. The web of the second reel is unwound in the second position, the splicing unit is moved toward the second unwind position until there is sufficient space to allow a further reel to be loaded into the first unwind position.

An apparatus and method for automatic splicing of rolls of sleeve material used in various packaging applications. The disclosed system will automatically splice the leading end of a new roll onto the trailing end of the old roll in an overlapped configuration. The apparatus performs an automatic cut and splice operation resulting in a splice of the two film rolls with tape applied to both sides of the splice joint where the new roll overlaps the cut end of the prior roll.

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.

The present invention relates to the field of SMT splicing belt processing equipment, and more particularly to a bonding machine for new and old SMT splicing belts. The machine comprises a supporting plate for supporting the old and new splicing belts, conveying devices for conveying the old and new splicing belts toward one another, and a bonding mechanism for bonding the old and new splicing belts together, the conveying devices and the bonding mechanism both being connected to a controller.
