A joining apparatus for supporting strips of adhesive labels comprises two modules each of which in turn comprises a conveying element of the respective supporting strip; a cutting element configured to cut a respective supporting strip; a joining element that can be configured in a first operating position, in which it keeps in position a respective supporting strip and/or a fixing element, and in a second operating position in which it abuts against the joining element of the other module so as to join the supporting strips; a locking element that can be configured between an active position and a passive position. In particular, at least one joining element can be removed from the respective module to allow the introduction of the fixing element even when the two modules are in the neared configuration to one another. The subject matter of the present patent application is also a joining process for supporting strips of adhesive labels.

A system and method for performing a splicing operation where the splicing apparatus is configured to orient the web to ensure the two sealing sides are presented to each other and the splice is always made on one side of the web.

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 device (1) for delivery of film for a station for packaging by plastic-wrapping, includes: at least two reels (2), each including at least one support shaft (3) for a film roll as well as a film guide (4), in particular in the form of a roller downstream from the shaft; a return roller (5), up to which an unwound film (6) travels from the roll of one of the reels (2); a loader for bringing the reserve film (9) from the roll of the at least one other reel (2) close to the unwound film. The loader includes a rotor (10), which rolls up the reserve film (9) around it in such a way as to bring it close to the unwound film (6). A machine that uses this device as well as a corresponding method are also described.

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.

A method for automatically replacing reels in an unwinding assembly capable of carrying out the handling operations of the reels, as well as preparing and joining the tail of the web of the finished reel with the head of the web of the new reel in a simple, efficient way, reducing the risk of malfunctions and maintaining the correct orientation of the new web as that of the finished web.

The present invention relates to a secondary battery electrode production system. The secondary electrode production system according to the present invention comprises: an unwinding portion (100) having multiple electrode material supply reels so as to continuously supply an electrode material; a notching portion (200) disclosed on a path of movement of the electrode material supplied from the unwinding portion (100); a cutting portion (400) disposed on the path of movement of the electrode material supplied from the notching portion (200) so as to generate the electrode; a vision inspection portion (600) for confirming whether the electrode is acceptable or not; and an electrode discharge portion (800) comprising a magazine for aligning and storing the electrode while interworking with the vision inspection portion.

A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film conveyance mechanism that conveys a first film so that a trailing end portion of the first film heads toward a film splicing position for splicing to a leading end portion of a second film, a first sensor detecting a mark on the first film, a second sensor detecting the mark at downstream, and a controller for the film conveyance mechanism. The controller judges, based on detection of the second sensor, that the trailing end portion of the first film has reached the splicing position and stops conveyance of the first film. The controller controls the conveyance mechanism so that the conveyance speed of the first film before the detection of the mark by the first sensor is faster than the speed after the detection.

A controller includes a shaft control unit that controls driving of a shaft drive source such that a standby side roll is rotated, and a unit control unit that presses a pressing roller against an outer peripheral surface of the standby side roll via a sheet of a supply side roll by performing torque control on a unit drive source in a state in which the pressing roller is positioned in an area from a control switching position to the outer peripheral surface of the standby side roll together with performing position control on the unit drive source in a state in which the pressing roller is positioned in an area farther away from the standby side roll than the control switching position away from the outer peripheral surface of the standby side roll by a preset distance while the standby side roll is rotated by the shaft control unit.

The invention relates to a method for a multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region and for which a normal length is predefined which is dependent on the respective application, in which material webs are removed from at least two material stores which are each associated with one or more tracks; and in which the material consumption of at least one material store is impacted during operation, in particular in dependence on residual quantities in the material stores, in that the length of the interleaved sheets is varied in the respective track or tracks with respect to the normal length at least for this material store.
