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 film-roll supply device improves replacement of a film roll in a bag-making and packaging machine. A film roll replacement device supplies a first film roll to a bag-making and packaging machine. The film roll replacement device is provided with a holding section and a first driving unit. The holding section receives the first film roll to be supplied to the bag-making and packaging machine. The first driving unit changes an orientation of the holding section between a first orientation used when receiving the first film roll and a second orientation used when supplying the first film roll to the bag-making and packaging machine.

According to some examples, a skew detection device comprises a first roller rotatable around a first axis, a second roller rotatable around a second axis, a first sensor, and a second sensor. The first sensor measures a first rotation parameter from the first roller and the second sensor measures a second rotation parameter from the second roller. A movement of a print media over the device rotates the first contact roller and the second roller, and a controller determines a skew of the print media based on the first and second rotation parameters captured by the first sensor and the second sensor.

The machine (1;100) comprises a winding station (3; 101), adapted to receive secondary winding cores (T) coaxial with, and adjacent to, one another. The machine further comprises a cutting device (11; 104) with a plurality of blades (13; 105), arranged upstream of the winding station (3; 101) with respect to the feeding direction of the web material (N) and adapted to slit the web material into a plurality of strips (S1-S5) of web material. An in-line measurement arrangement (81-87) is also provided for measuring the Poisson's ratio of the web material (N).

A sheet discharge apparatus includes a sheet discharging portion, a sheet supporting portion, a pivot member configured to pivot by being pressed by the sheet discharged from the sheet discharging portion, a detecting unit configured to detect a position of the pivot member, and a control unit configured to change a sheet interval. The control unit executes a first discharge operation in which at least one sheet is discharged, a second discharge operation in which sheets are discharged at a first sheet interval, and a third discharge operation in which at least one sheet is discharged at a second sheet interval that is longer than the first sheet interval, a number of sheets discharged in the second discharge operation being acquired based on a detection result of the detecting unit detected during the first discharge operation.

A winding machine (10) is disclosed comprising at least one reel holder (12) mounted on a supporting frame (11) and rotatable around its own axis (13), and a plurality of reels (1-4) mounted on the holder (12) and integrally rotatable therewith so that at least one first reel (1) is in at least one operative winding position of a bobbin (5). It is further described a respective method for the in-line winding of bobbins (5) of stretch film (6), comprising the steps of rotating a core (7) on a reel (1) in an operative winding position to wind the film (6) onto the core (7), positioning a contact roll (15a) in at least one proximal contacting position in which it contacts the winding bobbin (5) for facilitating the peripheral winding of the stretch film (6) on the core (7), bringing the reel (1) from the operative winding position of the bobbin (5) to an operative unloading position of the bobbin, positioning an accompanying roll (15b) in at least one proximal contacting position in which it contacts the bobbin (5) for facilitating the peripheral winding of the stretch film (6) on the bobbin (7), transversally cutting the stretch film (6) and unloading the bobbin (5). The movement of the contact roll (15a) and the accompanying roll (15b) is carried out by means of electric actuators (18a, 18b).

A sheet feeding apparatus includes a sheet stacker to stack at least one sheet; a sheet feed roller disposed at one side of the sheet stacker and to feed a sheet fed from the sheet stacker; a multi-feed prevention roller disposed to face the sheet feed roller and to prevent multi-feed of the sheet fed from the sheet stacker; a magnetic torque limiter disposed coaxially with the multi-feed prevention roller; a hall sensor disposed at one side of the magnetic torque limiter and to detect rotation of the magnetic torque limiter; and a controller configured to rotate the sheet feed roller in a state in which the sheet feed roller and the multi-feed prevention roller are in contact with each other without a sheet and to identify a lifetime of the multi-feed prevention roller by using a signal output from the hall sensor.

An inflatable packaging system includes an inflatable cushioning supply and a conveyance module. The conveyance module includes a sliding conveyor, a fixed conveyor, a belt-drive, and an encoder. The sliding conveyor is adjustable, relative to the fixed conveyor, such that a space between the sliding conveyor and the fixed conveyor is adjustable. The belt-drive displaces the inflatable cushioning supply through the space between the sliding conveyor and the fixed conveyor. The encoder is coupled to the belt-drive.

Examples of stalling of operation of imaging devices are described herein. In an example, the imaging device includes an input roller assembly to transport a medium in the imaging device and a line feed roller assembly disengagably coupled to the input roller assembly to selectively drive the input roller assembly. To stall the operation of the imaging device, a line feed shaft of the line feed roller assembly can be automatically disengaged from the input roller assembly to discontinue advance of the medium along a print path.

An electronic dispenser for dispensing flexible sheet material. A control circuit receives a plurality of signals and controls dispensing of the sheet material. A tear bar is mounted within the housing for severance of the sheet material. A pivotally mounted pawl member is located proximate to the tear bar such that movement of the sheet material into the tear bar for severance pivots the pawl member from a first position to a second position, such movement causing a signal to be sent to the control circuit. The dispensing mechanism is operative in a first mode to be responsive to a signal from a proximity sensor to dispense a sheet of material, and is operative in a second mode to dispense a next sheet in response to the signal activated by movement of the pawl member to the second position in response to dispensed sheet material being removed from the dispenser.
