A high-speed digital printing system includes two unwinding machines for two input coils for a paper web, an input unwinding and splicing installation and a printing station and in which the input installation supplies, in turn, the printing station with the web of the two coils. The system also includes a splicing and rewinding installation with an output cutting and splicing equipment for an incoming web emerging from the printing station and two rewinding machines with two output coils. The output equipment feeds alternatively the rewinding machines with the incoming web by cutting and splicing of a web of the two output coils without stopping printing. An electronic controller switches the functionality of the output cutting and splicing equipment and of the rewinding machines with setting of the output coils as an operating coil and a waiting coil and, viceversa, as a waiting coil and an operating coil.

The line comprises: an unwinding section (3) for unwinding parent reels (Ba, Bb, Bm) of web material (Na, Nb), with at least a first unwinding station (5; 7); at least a winding station (15) downstream of the unwinding section (3); a feed path from the unwinding section (3) toward the winding station (15);
The unwinding section (3) is associated with a loading arrangement of the parent reels (Bm), which comprises: an upender (253; 306) configured to upend the parent reels (Bm) positioning them with their axis horizontal; and a loading robot (263; 313), configured to position a parent reel (Bm; Ba, Bb) on an unwinding mandrel (9) of the unwinding section (3).

An apparatus for manufacturing an electrode includes a plurality of guide rollers configured to transport an electrode plate. The apparatus detects a defect on the electrode plate being transported and cut, upon detecting the defect, the electrode plate at a starting part of the defect on the electrode plate to form a defective electrode plate. The apparatus also includes a first taping part connecting the defective electrode plate to a defective electrode roll. The apparatus cuts the electrode plate at an ending part of the defect on the electrode plate to form a normal electrode plate. The apparatus connects the normal electrode plate separated from the defective electrode plate in the second cutting part with a normal electrode roll. The apparatus winds and transports the normal electrode roll.

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 method for splicing a material associated with an absorbent article, including: transporting the material in a direction of transport with a material wound around an entrance roll and a moving roll of a dancer unit; splicing a subsequent material with a preceding material which is a material being transported, by bonding a leading end portion of the subsequent material with the preceding material; and cutting the preceding material so that the total length of a bonded portion and an stacking portion is larger than a path length of the material from a downstream end of a winding portion of the material that is wound around the entrance roll to an upstream end of another winding portion of the material that is wound around the moving roll positioned at a reference position.

A method of labeling products includes providing a labeling machine, performing on command, by a splicing device, a splicing between a first splicing region, obtained from a backing ribbon being wound onto a first winding element, and a second splicing region, which is formed on a connection element that is connected to a second winding element, cutting on command, by a first cutting device, said backing ribbon at the portion that extends between said first splicing region and the backing ribbon wound onto the first winding element, and continuously splicing the backing ribbon of the adhesive labels unwound from the feeder spools and of the backing ribbon being wound onto the winding elements, cutting said backing ribbon, by a first cutting device, simultaneously or after the splice between said first splicing region and said second splicing region on the part of said first splicing device, and labeling said products with said labels.

A recording device includes a conveyance mechanism, a recording mechanism, a rotational mechanism of a plurality of take-up spindles, and a control unit. The conveyance mechanism is configured to convey a recording medium intermittently in a conveyance direction. The recording mechanism is configured to record by reciprocatingly scanning a recording head in a direction that intersects with the conveyance direction. The rotational mechanism is configured to take up the recording medium. The control unit is configured to control the conveyance mechanism and the rotational mechanism to substantially synchronize conveying of the recording medium by the conveyance mechanism and taking-up of the recording medium by the rotational mechanism.
