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.

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.

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.

The present application relates to a roll replacing device and a tab welding apparatus. The roll replacing device includes an unwinding mechanism, a first fixing mechanism, a second fixing mechanism, a cutting mechanism, and a strip connection mechanism; wherein the first fixing mechanism is capable of following a sliding bracket to move along a first direction until a spare material strip fixed by the first fixing mechanism and a working material strip fixed by the second fixing mechanism are aligned at a strip connection station, and allows the strip connection mechanism to connect the working material strip and the spare material strip which are aligned at the strip connection station.

An assembly for feeding backing ribbon for adhesive labels for labeling products to be labeled, comprising a splicing device and at least two supporting elements for the backing ribbon, the splicing device being intended to perform on command the splice between a first splicing region, formed on a first backing ribbon being unwound from a first supporting element, and a second splicing region, formed on a second backing ribbon wound on a second supporting element, the first backing ribbon supporting a plurality of adhesive labels which are arranged, mutually spaced, on the face directed toward the second splicing region; the first backing ribbon having, when associated with the respective first supporting element, at least one portion that is free from self-adhesive labels and forms the first splicing region; the portion is located substantially at the end of the first backing ribbon that is associated with the first supporting element.

A splicing assembly for rolled sheet material, including first and second shafts for support of sheet material and a drive assembly for selectively dispensing sheet material. The assembly further includes a splicing apparatus for uniting a replacement with a winding down roll, and an egress guide assembly for receipt of dispensed sheet material exiting the splicing apparatus and passage of same intermediate the shafts. The splicing apparatus includes first and second sealing elements, and first and second carriages adapted and disposed for translation towards their respective sealing elements, a free end portion of sheet material of the replacement roll supported upon the first/second shaft for selective retention by the second/first sheet material carriage, and for translation to, and thereafter with, a portion of sheet material of the winding down roll supported upon the second/first shaft for urged combined engagement with a corresponding sealing element.

An assembly for feeding backing ribbon for adhesive labels for labeling products to be labeled, comprising a splicing device and at least two supporting elements for the backing ribbon, the splicing device being intended to perform on command the splice between a first splicing region, formed on a first backing ribbon being unwound from a first supporting element, and a second splicing region, formed on a second backing ribbon wound on a second supporting element, the first backing ribbon supporting a plurality of adhesive labels which are arranged, mutually spaced, on the face directed toward the second splicing region; the first backing ribbon having, when associated with the respective first supporting element, at least one portion that is free from self-adhesive labels and forms the first splicing region; the portion is located substantially at the end of the first backing ribbon that is associated with the first supporting element.

An automatic replacement apparatus for a feed material includes a discharge unit discharging a feed material to the outside, a pair of feed units disposed to be adjacent to the discharge unit and having a feed roll around which the feed material is wound, and a pair of material joint units respectively provided in the pair of feed units connecting a front end of a first feed material waiting in a first feed unit, one of the pair of feed units, and an end of a second feed material being transferred from a second feed unit, the other of the pair of feed units, to the discharge unit in a butt joint manner.

A separator supply device is provided. The separator supply device includes a frame, a separator supply portion mounted on the frame, and including a first reel mounting portion configured to accommodate a first reel configured to be wound with a first separator, and a second reel mounting portion configured to accommodate a second reel, spaced apart from the first reel, and configured to be wound with a second separator, and a separator connection portion configured to adsorb an end of the first separator unwound from the first reel and an end of the second separator unwound from the second reel and to connect the first separator to the second separator.
