Adhesive tape for flying splices of flat web materials, in particular flat web materials with nonpolar surfaces, said adhesive tape at least comprising an upper self-adhesive compound layer, an inner adhesive tape area adapted as a flat predetermined breaking point, and a lower self-adhesive compound on the underside of the inner adhesive tape area, wherein a natural rubber adhesive compound is used as the self-adhesive compound for at least the upper self-adhesive compound layer, as well as methods for flying splices of flat web material wound onto rolls, in particular with nonpolar surfaces, using a corresponding adhesive tape.

A sheet delivery system includes: a joining unit which joins, to an intermediate section of a sheet being delivered from a delivery-side original material roll, an end section of a sheet W of a standby-side original material roll; and an operation robot which retrieves the end section of the sheet from the standby-side original material roll and which conveys the end section of the sheet to the joining unit. The sheet delivery system sets, in advance, a sheet retrieval position at which the sheet is retrieved from each of the original material rolls, for each of the original material rolls. The operation robot is configured to convey the end section of the sheet from each of the sheet retrieval positions to the joining unit.

A joining unit includes: a suction holding member having a suction surface configured to suction an end section of a sheet; a moving mechanism configured to move the suction surface toward an intermediate section of a sheet of a delivery-side original material roll along a path set in advance so that tension is applied to the sheet; and a regulating mechanism that is configured to switch between a regulated state in which a movement of the end section of the sheet with respect to the suction holding member due to the tension is regulated and an allowable state in which the movement of the end section of the sheet with respect to the suction holding member is allowed. The controller switches the regulating mechanism to the regulated state during the movement of the suction surface toward the intermediate section of the sheet of the delivery-side original material roll.

A system and method for automatic splicing of rolls of sleeve material used in various packaging markets is provided. The system will automatically splice the prepared end of a new roll onto the expiring end of the prior roll. The system performs an automatic cut and splice operation resulting in a butt splice of the two rolls with tape applied to both sides of the splice joint. The splice can be done in-registration to provide a consistent product repeat length between expiring and new rolls.

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 splice mechanism (100) for a packaging assembly (10), the packaging assembly (10) including: a former shoulder (12); a controller (14); a film drive (16) controlled by the controller (14) for feeding a film (112) at a film speed to the former shoulder (12) to form a tubular film (22) moving in a film direction (20); a sealing device (24) to seal the tubular film (22) in a first sealing direction (26), the first sealing direction (26) being parallel to the film direction (20); a set of jaws (28) controlled by the controller (14) and movable at a jaw speed to engage and seal the tubular film (22) in a second sealing direction (30) to form a first seal (32) and a second seal (34) in each bag, thereby forming a closed bag (36), the splice mechanism (100) including: an active film roll (110) from which film (112) is drawn to be fed to the former shoulder (12) by the film drive (16); a second film roll (120) having film (122) for feeding to the former shoulder (12); a film roll holder (130) holding the active film roll (110) and the second film roll (120) such that film (112) from the active film roll (110) extends along a film path (140) to the former shoulder (12) and the second film roll (120) is accessible; a splice roller (150) against which film (122) from the second film roll (120) is placed, the film (122) having a film end (124), the film end (124) having an adhesive (126), the splice roller (150) being movable between a free position, wherein the film path (140) is unimpeded by the splice roller (150), and a splice position, wherein the film path (140) is tangential to the splice roller (150) at a splice point (142) on the film path (140).

The present invention relates to an electrode connection apparatus including a transfer unit configured to transfer a start portion of a standby electrode roll in a state of gripping the start portion, a leading unit configured to move upwards in a state of gripping the start portion of the standby electrode roll transferred by the transfer unit, a first connection unit configured to fix the standby electrode roll transferred by the leading unit, a second connection unit configured to fix an end portion of a moving electrode roll, and a taping unit configured to connect the standby electrode roll and the moving electrode roll to each other, whereby it is possible to automatically connect the electrode rolls to each other during an electrode manufacturing process performed as a roll-to-roll process.
