A method for splicing a web of packaging material is provided. The method involves guiding a first web of packaging material through an automatic splicing device, determining the position of at least one mark of the first web of packaging material by a detector, moving the first web of packaging material based on the position of the at least one mark of the first web of packaging material such that a specific area of the first web of packaging material is arranged in proximity to a cutting unit, and cutting the first web of packaging material in order to form a separate leading part of the first web of packaging material. The method may also involve introducing a new leading part of a second web of packaging material into the automatic splicing device, determining the position of at least one mark of the second web of packaging material, moving the second web of packaging material based on the position of the at least one mark of the second web of packaging material such that a specific area of the second web of packaging material is arranged in proximity to a sealing arm of the cutting unit, and sealing the separate leading part of the first web of packaging material and the second web of packaging material.

Provided is a bag making and packaging machine having superior workability in film joining work. A bag making and packaging machine is a bag making and packaging machine that uses film having at least one character or a figure printed on its front side, and is equipped with a film roll support unit, a conveyance unit, a bag making unit, and a light emitting component. The film roll support unit supports a film roll in which the film is wound in a roll. The bag making unit processes the film to make bags. The conveyance unit is positioned between the film roll support unit and the bag making unit. The conveyance unit feeds the film to the bag making unit. The light emitting component illuminates, from the direction of the front side of the film, the film positioned between the film roll support unit and the conveyance unit.

A high-speed digital printing system includes two unwinding machines for two input coils for a paper web, an input unwinding and splicing installation and a printing station and in which the input installation supplies, in turn, the printing station with the web of the two coils. The system also includes a splicing and rewinding installation with an output cutting and splicing equipment for an incoming web emerging from the printing station and two rewinding machines with two output coils. The output equipment feeds alternatively the rewinding machines with the incoming web by cutting and splicing of a web of the two output coils without stopping printing. An electronic controller switches the functionality of the output cutting and splicing equipment and of the rewinding machines with setting of the output coils as an operating coil and a waiting coil and, viceversa, as a waiting coil and an operating coil.

An apparatus (100) for splicing a patterned web (108) is provided. The apparatus includes first and second unwind spindles (110, 114) engaging a new roll (112) of patterned web (108) and expiring roll (116) of patterned web, respectively, a first web indexing mechanism (104) capable of linearly translating the patterned web from the new roll (112) along its travel direction; a first clamp surface (129) that extends across the patterned web from the new roll; a second clamp surface (131) that extends across the patterned web from the expiring roll (116); and a cutting mechanism (132, 132) for severing the patterned web from the expiring roll (116). The apparatus further includes a second web indexing mechanism capable of linearly translating the patterned web from the expiring roll along its travel direction, wherein the first and second web indexing mechanisms are independently operable to align registration features of the patterned web on the new roll and expiring roll with each other. The first and second clamp surfaces can be brought together to create a registered splice of the patterned web between the new and expiring rolls.
