A post-processing apparatus includes a side edge alignment section configured to move to a first position, a second position, that is farther from the side edges in the width direction than the first position, and a third position, that is between the first position and the second position in the width direction. The post-processing apparatus is configured to execute an adjustment operation of moving the side edge alignment section from the second position to the third position and an alignment operation of aligning the medium by causing the side edge alignment section to abut on the medium in the first position. The adjustment operation is executed while the first transport section transports the medium and the alignment operation is executed after the adjustment operation is performed and after the medium reaches a tip end alignment section.

An image reading apparatus includes a first stacking unit having a stacking surface, and an abutment portion that abuts a document stacked on the stacking surface, a feeding unit, a reading unit, a second stacking unit, a first detection unit, a rotating shaft, a drive unit, and a control unit. The second stacking unit receives the document fed by the feeding unit and read by the reading unit. The first detection unit detects presence or absence of the document stacked on the first stacking unit. The drive unit rotates the first stacking unit around the rotating shaft rotatably supporting the first stacking unit. At a predetermined timing after the first detection unit detects the absence of the document on the first stacking unit, the control unit controls the drive unit to rotate the first stacking unit in a direction with which the abutment portion is lowered.

In some examples, a sheet processing machine includes at least one transport means of an infeed system, and the infeed system includes at least one cam mechanism including, in each case, at least one cam disk having an axis of rotation. At least one scanning element is arranged in each case to rest against the at least one cam disk. The at least one scanning element is connected to the at least one transport means via at least one drive lever. The at least one drive lever in each case has at least one mounting point. The mounting point and the axis of rotation may be adjusted relative to one another, and a position displacement of the mounting point relative to the axis of rotation may compensate for at least one position error of the at least one sheet.

An installation includes a guide arrangement, guiding a material web, a conveying speed detection device, detecting a conveying speed of the conveyed material web, and a winding arrangement arranged downstream from the conveying speed detection device. The winding arrangement includes a rotatably mounted winding device, winding up the material web. The winding device is non-circular in cross section at least in a material web winding-up region, folding the material web. The winding arrangement has a rotary drive, in driving connection with the winding device, driving the winding device in rotation. An actuating device is at least temporarily in signal communication with the conveying speed detection device for receiving conveying speed signals therefrom, characterizing the respective conveying speed of the material web, and is at least temporarily in signal communication with the rotary drive for actuating the latter upon folding the material web in dependence on the conveying speed signals.

A method and apparatus for depositing discrete elements on a support element. The discrete elements may be separated from each other or joined to form a continuous web. The discrete elements are fed into a pick-up station defined at a rotor which includes circumferentially adjacent pick-up members. Each discrete element is associated with a respective pick-up member having a first orientation with respect to a respective second axis of rotation. Each pick-up member is moved along the rotation direction towards a release position downstream with an at least partially accelerated or decelerated motion. Each pick-up member is rotated about the respective second axis of rotation until it takes, at the release position, a second orientation. Each discrete element is released on a support element at the release position. Each pick-up member is subsequently moved towards the pick-up station with an at least partially decelerated or accelerated motion.
