A sheet delivery system includes: an end section detector which detects a position of an end section of a sheet; an end section conveying apparatus which holds the end section of the sheet and which conveys the end section of the sheet to a joining unit; a roll driving motor which rotationally drives a standby-side original material roll around a central axis thereof; and a suction roller which is capable of coming into rolling contact with an outer peripheral surface of the standby-side original material roll, and which includes an outer peripheral surface capable of suctioning the end section of the sheet in order to separate the end section of the sheet from the standby-side original material roll. The end section detector is attached at a position which enables detection of the end section of the sheet separated from the standby-side original material roll by the suction roller.

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.

A sheet-feeding system includes a holding part which holds an end portion of a sheet, a nozzle part for discharging an adhesive agent for joining sheets to each other, and a nozzle moving unit which supports the nozzle part such that the nozzle part is made movable within a region including both temporarily holding parts, in which when a sheet joining condition is established where a remaining amount of the sheet on one original sheet roll becomes equal to or below a predetermined remaining amount, an end portion of the sheet on the other original sheet roll is conveyed to the temporarily holding part by the holding part and, thereafter, the nozzle part is moved to the temporarily holding part, and the adhesive agent is discharged to the end portion of the sheet from the nozzle part.

The invention concerns a splicing facility for splicing material webs. The splicing facility comprises a first dispensing device for dispensing a finite first material web from a first material web roll, a second dispensing device for dispensing a finite second material web from a second material web roll, a third dispensing device for dispensing a third material web, a first splicing device for splicing together the finite first material web and the finite second material web to an endless material web and a second splicing device for splicing together the third material web and the finite first material web or the finite second material web to the endless material web. The first splicing device and the second splicing device are arranged at different heights.

When a remaining amount of a sheet on one original sheet roll is equal to or less than a predetermined remaining amount, a pair of holding pads is brought into a first posture where holding surfaces are opened, and the holding surface of one holding pad is pressed to a joining end portion from the outside of the original sheet roll in a radial direction of the other original sheet roll. Further, the holding pad is moved such that the joining end portion is separated toward the outside of the original sheet roll in the radial direction. Further, the posture of the pair of holding pads is changed into a second posture where the holding surfaces approach each other, and the joining end portion is conveyed to a joining part in a state where the joining end portion is sandwiched between the holding surfaces of the pair of holding pads.

A device for splicing and continuously providing an outgoing film web includes a splicing unit for splicing a first or a second incoming film web to the outgoing film web, and a clamping unit and an intermediate film storage for the outgoing film web. The splicing unit includes a first sealing jaw with a first holding device for the outgoing film web, and a first cutting device for severing the outgoing film web in the region of the first sealing jaw. The splicing unit includes a second sealing jaw with a second holding device alternately for the first or the second incoming film web, and a second cutting device for severing this incoming film web. The sealing jaws with their respective holding devices can be displaced relative to one another out of the region of action of their first and second cutting devices into their mutual region of action.

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.

A splice arrangement includes an unwinding arrangement for unwinding a finite first material web from a first material roll or a finite second material web from a second material roll, a braking arrangement for applying a braking force to the unwinding arrangement and/or the finite material web being unwound, a connection arrangement for connecting the finite material webs to form an endless material web, a storage trolley for the uninterrupted conveying of the endless material web, at least one material web tension-influencing device arranged before the storage trolley, and an actuation device, which is in signal connection with the at least one material web tension-influencing device for actuating the same.
