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.

The tipping paper feed assembly (1) comprising a first feed device adapted to supply a first tipping paper web (4) that is fed into apparatus for smoking article manufacture, and a second feed device adapted to supply a second tipping paper web (11). The tipping paper feed assembly (1) also comprises a splice mechanism (12) adapted to attach the first and second tipping paper webs (4, 11) together for changeover between the first and the second feed devices. The tipping paper feed device (1) also comprises a registration system configured to register features of each tipping paper web (4, 11) prior to attaching said first and second tipping paper webs together with said features in register.

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: an end section detector which detects a position of an end section of a sheet; an operation robot 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 the 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.

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.

Proposed are automatic splicing equipment for a secondary battery and a method thereof and, more specifically, automatic splicing equipment for a secondary battery and a method thereof for improving process efficiency by preventing interruption in film supply during the manufacturing process by connecting a standby spare second film to a film being supplied when the film being supplied is exhausted while supplying the film for a back-end process.

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.

An unwinder for unwinding reels of paper includes a supporting structure partially closed and defining an internal space suitable for unwinding at least one reel; the supporting structure includes: a first lateral support; a second lateral support spaced from the first support; a crosspiece interposed above between the first and the second support defining with the first support and second support the partially closed structure; the unwinder further includes: a first axial unwinding system placed at the first support and configured to axially unwind a first reel; a second axial unwinding system placed at the second support and configured to unwind a second reel; a joining device placed at the crosspiece and configured to make a joint between a first ply belonging to the first reel and a second ply belonging to the second reel to perform a reel exchange.

The invention relates to a device for joining webs of material for the production of energy cells, in particular electrode webs, wherein a running-out web of material can be joined to a new web of material. A first pivoting element is provided for the new web of material and a second pivoting element is provided for the running-out web of material, wherein the first pivoting element is adapted to hold the leading end of the new web of material and wherein the second pivoting element is adapted to deflect the running-out web of material in the direction of the first pivoting element. A cutting device is provided, which is adapted to cut or weaken the running-out web of material deflected by the second pivoting element to produce a web end of the running-out web of material at a separating line. The device is adapted to accelerate the leading end of the new web of material with the first pivoting element and to synchronize with the running-out web of material at the speed at which the web end of the running-out web of material deflected by the second pivoting element is conveyed. The leading end of the new web of material can be joined to the web end of the running-out web of material between the first and second pivoting elements by means of at least one adhesive tape.
