The present invention is to provide a sheet aligning apparatus that is capable of detecting misalignment. A control portion of a post-processing apparatus causes a front aligning member and a rear aligning member to be moved to an aligning position to align sheets conveyed to a processing tray, and determines whether an electrostatic capacitance sensor detects misalignment (sheet shifting from a sheet bundle). After the control portion determines that there is no misalignment, the control portion performs detection strength adjusting for a sensor and initial value setting for detecting misalignment of a next sheet.

The coiled foil rolls are reinforced in their edge region by folding. The coiled foil rolls are made by supplying a foil to coiling devices; cutting the foil in a conveying direction with a knife so that at least two foil sections are created which extend in a conveying direction; folding the edge regions of the foil sections by a folding device and laying the folded sections and the remaining part of the foil section on each other; and coiling the foil sections with the coiling devices. The knife or the folding device are moved simultaneous oscillating back and forth in a direction transversal to the conveying direction during the coiling of the foil sections.

The present invention relates to a winding conveying unit for an electrode plate of a rechargeable battery for an electric vehicle which can manufacture electric rolls by conveying and winding an electrode from the electric rolls without breakage when the electrode rolls are manufactured by using electrode rolls in which an electrode is configured in a direction to fill the electrode rolls in a box at a high integration in a manufacturing process of a rechargeable battery for an electric vehicle that is configured by stacking electrode rolls in a sealed (cylindrical or angular) box. The present invention provides a winding conveying unit for an electrode plate of a rechargeable battery for an electric vehicle, which can prevent a breakage when an electrode is conveyed, by providing a guide roller at a moving position of the electrode on an external surface of a conveying roller.

A post-processing device includes a sheet transporting section that transports one or more sheets, a cutting section that cuts the sheet along a transporting direction of the sheet being transported by the sheet transporting section and a paper piece transporting section that transports a paper piece cut by the cutting section, and a transporting speed of the paper piece transporting section is set lower than a transporting speed of the sheet transporting section.

The present invention provides a guide device for guiding print medium onto a take-up roll in a printing system. The guide device comprises a first guide member presenting a substantially planar surface for limiting or preventing lateral deviation of a printed medium output from the printing system as the medium moves along a transport path towards a take-up roll for winding or taking up a length of the medium. The first guide member is stationary in use. A position of the first guide member is adjustable in a direction transverse to the transport path for setting the position to limit or prevent lateral deviation of the medium along the transport path. The guide device further comprises a second guide member presenting a support surface configured and arranged to support the medium thereon as the medium travels along the transport path towards the take-up roll. The first guide member and the second guide member are preferably integrally formed as a guide unit. Further, the invention provides a printing system which incorporates such a guide device.
