A sheet binding device includes a sheet shifting unit, a tape cutter, and a tape attachment unit. The sheet shifting unit has a guide and is configured to stack multiple sheets on the guide with edge portions that are shifted from each other to form a sheet bundle. The tape cutter cuts tape with a target length that is varied in accordance with a thickness of the sheet bundle. The tape attachment unit is configured to attach the cut tape having the target length to an edge portion of the sheet bundle.

A loading apparatus including a support surface facing forward and inclined vertically downward from a paper exit of a printer body and configured to come into contact with a first surface of a printed material, the first surface forming a vertically downward surface in the paper exit, a braking member provided near the paper exit and configured to come into contact with the first surface and to hold a part, which contacts therewith, of the printed material, and a stopper configured to come into contact with a downstream leading end of the printed material at a paper ejection direction in which the printed material is ejected. The stopper is configured to be located at a first position and a second position on the support surface, in which a distance between the second position and the paper exit is greater than a distance between the first position and the paper exit.

Layer constructions allow an adhesive tape to be wound to form a spool simply and with relatively uncomplicated apparatus. At least one layered construction comprises: an adhesive tape comprising at least one outer layer of pressure-sensitive adhesive; a release liner lying on the outer layer of pressure-sensitive adhesive; and an interliner lying on the side of the adhesive tape opposite the outer layer of pressure-sensitive adhesive, at least the side of the interliner facing away from the adhesive tape being adhesively furnished, wherein all layers of the layered construction finish substantially flush with respect to each other. At least one spool comprising a spool core and the at least one layered construction wound crosswise in a plurality of plies on said core, and a method for producing the at least one spool are also disclosed.

This application relates to a winding and unwinding apparatus and a preparation system of electrode plate. The apparatus includes supports, a rotating shaft, a rotating turret, and a power assembly. The rotating shaft is rotatably disposed on the support. The rotating turret is disposed on the rotating shaft and capable of rotating along with the rotating shaft so as to switch between at least two target operation positions. The power assembly includes a first power source and a magnetic powder clutch. The rotating shaft and the first power source are in transmission connection with each other via the magnetic powder clutch. The magnetic powder clutch is configured to control the rotating shaft to remain stationary when the rotating turret is hovering at each target operation position.

This application discloses a rewinding apparatus and a rewinding method. The rewinding apparatus is configured to rewind a strip. The rewinding apparatus includes a rewinding mechanism and a switching mechanism. The rewinding mechanism includes two shafts that are opposite to each other along a first direction and spaced out. The two shafts are configured to rewind the strip along different conveyance paths separately. The switching mechanism includes a moving roller. The moving roller is configured to drive the strip to switch from one shaft to another shaft so that the strip switches from one conveyance path to another conveyance path. The rewinding apparatus and rewinding method disclosed in this application achieve high space efficiency and high switching efficiency.

Job types include a first job type in which a second process is performed after a first process and a second job type in which the first process is performed and the second process is not performed. In a printer, a recording medium is allowed to be sandwiched by a center pinching roller and driving rollers. A controller of the printer includes a first primary elevation controller that controls the center pinching roller such that the center pinching roller stays down on the driving rollers to hold the recording medium in performing the first process in the first job type and a first secondary elevation controller that controls the center pinching roller to move upward and stay away from the driving rollers in performing the first process in the second job type.

An image forming apparatus includes an image forming unit to form an image on a sheet, an intermediate processing tray where sheets conveyed through a first conveyance path are stacked as a sheet bundle, a sensor disposed at a second conveyance path to detect a conveyed sheet bundle, and a stacking tray in which sheets discharged through a discharging path diverging from the first conveyance path are stacked. In response to a sensor detected paper jam, a control unit determines the intermediate processing tray as the discharging destination for a sheet among the remaining sheets, and determines the stacking tray as the discharging destination for a sheet among the remaining sheets. After the paper jam is cleared, the control unit causes execution of bookbinding and cutting for a sheet bundle including the remaining sheets stacked in the intermediate processing tray.

A sheet product package and method of making discrete plastic sheets includes a package enclosure with a dispensing opening structure and a plurality of discrete plastic sheets arranged in a stack. The plurality of discrete plastic sheets are disposed within the package enclosure, and each of the plurality of discrete plastic sheets is electrostatically charged. In the method of making the dispensable plastic sheets, electrostatically charged discrete plastic sheets are formed and arranged in a stack. The method may include forming a continuous plastic film, cutting the continuous plastic film into discrete plastic sheets, and, after cutting, electrostatically charging the discrete plastic sheets.

An image forming apparatus includes a first sheet storage, a second sheet storage, an image forming unit, a sheet conveyer configured to convey sheets from the first and second sheet storages to the image forming unit, and a controller. The controller is configured to set new sheets as a type of sheets stored in the first sheet storage and image-decolored sheets as a type of sheets stored in the second sheet storage, switch a sheet feeding source from the first sheet storage to the second sheet storage when the first sheet storage runs out of sheets during execution of a first image forming job that includes no sheet post-processing, and stop image forming by the image forming unit when the first sheet storage runs out of sheets during execution of a second image forming job that includes sheet post-processing.
