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 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.

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.

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.

A method for feeding a production line of absorbent sanitary articles with a layer of a virgin multilayer tape including providing a head free end of the virgin multilayer tape partially unwound from a respective virgin spool; providing a tail free end of a multilayer tape in use; applying a first connecting element on a first layer of the virgin multilayer tape and on a first layer of the multilayer tape in use at the head free end and tail free end; applying a second connecting element on a second layer of the virgin multilayer tape and on a second layer of the multilayer tape in use at the head free end and tail free end; pulling the first layer of the virgin multilayer tape in a first direction; pulling the second layer of the virgin multilayer tape in a second direction.

The invention comprises a method and a device for changing removable carrier units (8a, 8b) with flat packaging material (10) wound on supply rolls (9), in particular, packaging film (11) within a packaging machine (3), which is equipped with devices for at least partially wrapping piece goods, containers, article groups, etc., with flat packaging material (10). With the method removable carrier units (8a, 8b) with new supply rolls (9) are fed in a series one after the other to a work area (AB) of a handling device (5), the work area (AB) of which extends into at least one position of the operating position of the removable carrier unit (8a, 8b) arranged in the packaging machine (3), which is equipped with a supply roll (9), so that it replaces removable carrier units (8a, 8b) located in the packaging machine (3) and used up supply rolls (9) with new removable carrier units (8a, 8b) with in each case a new supply roll (9). Here respective removable carrier units (8a, 8b) are inserted alternately in at least two different installation positions of the packaging machine (3) and its flat packaging material (10) is connected with the packaging material still located in the packaging machine (3).

Disclosed are a reel changing and belt receiving module, a reel changing and automatic belt receiving mechanism, a winding device and a production line. The reel changing and belt receiving module includes: a horizontal moving assembly and a forward and backward moving assembly. An output end of the forward and backward moving assembly is provided with a belt receiving roller and a belt receiving roller driven assembly, and a cutter assembly is provided on the belt receiving roller. An output end of the belt receiving roller driven assembly is connected to one end of the belt receiving roller and is configured to drive the belt receiving roller to rotate. The reel changing and automatic belt receiving mechanism includes an installation main plate provided with a rotation roller a first roller cylinder and a second roller cylinder.

In a bagmaking-and-packaging apparatus, when switching from bagmaking using a first film to bagmaking using a second film, a first impulse sealer interconnects an end-of-bagmaking film of the first film and a starting end scrap of the second film to form a first interconnected film. A second impulse sealer interconnects a third part on a starting end side of the first F1 and a fourth part of the second film to form a second interconnected film.

A method and system for joining strips of battery grid comprises feeding a first strip of battery grid into a processing station at a predetermined feed rate, and progressively increasing the path length of the first strip until a target path length is reached. When the end of the first strip is reached, the path length of the first strip is progressively decreased while holding the end of the first strip. The rate of decrease allows the first strip to continue to be delivered into the processing station at the predetermined feed rate. A second strip is advanced from a second feed supply to a position adjacent the end of the first strip. The adjacent ends are joined by laser welding. The decreasing of the path length is stopped, and the second strip of battery grid is fed into the processing station at the predetermined feed rate.

A roll exchange chamber for exchanging a substrate roll is described. The roll exchange chamber includes a rotatable base construction being rotatable around a central axis. The base construction comprises a first roll holder for holding a first substrate roll, a second roll holder for holding a second substrate roll, and a wall for providing a first compartment and a second compartment in the roll exchange chamber. The wall is arranged between the first roll holder and the second roll holder. Further, a roll-to-roll processing system with a roll exchange chamber as well as a method of continuously providing a flexible substrate in a roll-to-roll processing system are described.
