A splice arrangement includes an unwinding arrangement for unwinding a finite first material web from a first material roll or a finite second material web from a second material roll, a braking arrangement for applying a braking force to the unwinding arrangement and/or the finite material web being unwound, a connection arrangement for connecting the finite material webs to form an endless material web, a storage trolley for the uninterrupted conveying of the endless material web, at least one material web tension-influencing device arranged before the storage trolley, and an actuation device, which is in signal connection with the at least one material web tension-influencing device for actuating the same.

The invention relates to a method for adapting at least one winding parameter of a winding device during winding of a film web on a winding core, having the following steps:—conveying of the film web along a measuring path between a first driven roll and a second driven roll—increasing of the web tension of the film web between the first roll and the second roll—continuous detecting of the drive parameters of the first roll and of the second roll at least in the form of the torque and the circumferential speed,—determining of a stress-strain diagram from the detected drive parameters—adapting of at least one winding parameter of the winding device on the basis of the determined stress-strain diagram in order to achieve a defined elongation of the film web during winding on the winding core.

A stacking apparatus for value documents, having a stack deposit device and a braking device which is arranged along the transport path of the value documents immediately before the stack deposit device. On the transport shaft of the braking device at least one driving roller is firmly mounted and at least one roller rotatably supported on the transport shaft. At least one cam roller is firmly mounted on a braking shaft of the braking device and at least one eccentric roller. By a rotation of the braking shaft, the eccentric roller can electively be brought in engagement with the opposing driving roller so that a value document becomes clamped between these, or be brought out of engagement with the opposing driving roller, so that the value document is no longer clamped between these, but rather is brakable by the engagement between the cam roller and the rotatably supported roller.

A meandering correction apparatus includes a transport mechanism, an orientation measurement part, a Young's modulus calculation part, a meandering prediction part and a meandering correction part. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path. The orientation measurement part measures fiber orientations of the base material in respective measurement regions on the transport path, the measurement regions being different in widthwise position from each other. The Young's modulus calculation part calculates Young's moduli of the base material for the respective measurement regions, based on the fiber orientations. The meandering prediction part predicts subsequent meandering of the base material, based on the Young's moduli, to output meandering prediction information. The meandering correction part corrects the widthwise position of the base material, based on the meandering prediction information. The meandering correction is made based on the fiber orientations of the base material. Thus, the widthwise position of the base material is corrected without depending on only edge sensors.

An image forming apparatus, having a housing with an opening, an image forming unit, a path to guide a recording medium toward the opening, a reversible roller disposed in the path, and an intermediate reversible roller disposed between the image forming unit and the reversible roller, is provided. A rotating direction of the reversible roller is switchable between a first rotating direction and a second rotating direction opposite from the first rotating direction. A circumferential speed of the reversible roller is switchable between a predetermined circumferential speed and none. A rotating direction of the intermediate reversible roller is switchable between a third rotating direction and a fourth rotating direction opposite from the third rotating direction. The circumferential speed of the reversible roller in the first rotating direction is reduced to be lower than the predetermined circumferential speed while the intermediate reversible roller is rotating in the third rotating direction.

A bag-making and packaging machine includes a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film roll holding unit that rotatably holds a first film roll, a film temporary placement member on which a vicinity of a leading end portion of a first film wound into the first film roll is manually temporarily placed when attaching the first film roll to the film roll holding unit, a leading end portion detection sensor configured to detect that the leading end portion of the first film is positioned in a prescribed position, and a controller configured to control a rotating mechanism to convey the first film along a predetermined conveyance path until the leading end portion detection sensor detects that the leading end portion of the first film is positioned in the prescribed position.
