A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.

A sheet storage that stores a sheet includes: a reel around which a tape is wound; a first drive unit that rotates the reel around a rotation axis; a drum that is connected to the reel via the tape and winds the tape wound around the reel together with the sheet; a second drive unit that rotates the drum around a rotation axis; and a control circuitry that controls at least one of the first drive unit and/or the second drive unit to change tension acting on the tape according to a state of the sheet storage.

A sheet processing apparatus includes: a first storage that is a winding-type storage unit where a sheet is wound around a drum together with a tape and stored; a second storage that stores the sheet; a transport unit that transports the sheet to the second storage at a first transport speed and transports the sheet from the second storage to the first storage at a second transport speed; and a processing circuitry that controls the first storage, the second storage, and the transport unit so that the second transport speed is slower than the first transport speed and a winding speed for winding the sheet by the first storage is a first winding speed that is slower than the second transport speed.

A sheet stacking apparatus is provided. A conveyor unit performs stacking of sheets discharged from a printing apparatus and conveying of stacked sheets. A detection unit detects whether or not the printing apparatus is currently discharging a sheet. A control unit, so as to secure a stacking space for a sheet discharged from the printing apparatus on the conveyor unit, controls a feeding operation of the conveyor unit correspondingly to a period of time over which the detection unit detected that the printing apparatus is discharging a sheet.

A transport portion includes a device main body, an upper guide portion, and a lower guide portion. In the device main body, a descending path and an ascending path overlap each other in a Z direction. The upper guide portion is configured to be moved outward with respect to the device main body and is positioned above the descending path and the ascending path in a state in which the upper guide portion is stored. The lower guide portion forms the descending path and the ascending path together with the upper guide portion. The lower guide portion includes a first path forming member and a second path forming member. The first path forming member forms the descending path and at least partially overlaps a moving area of the upper guide portion at a first position and does not overlap the moving area at a second position.

The present application discloses a post-processing apparatus including a second tray which receives a sheet stack ejected from a first tray, a pushing mechanism including a pushing portion which pushes the sheet stack against the second tray, a motion detector which detects a motion of the pushing mechanism, and a controller including an ejection controller which controls an ejector. When the ejector ejects the sheet stack, the pushing mechanism moves the pushing portion in a first direction away from the second tray. When the ejector finishes ejection of the sheet stack, the pushing mechanism moves the pushing portion in a second direction which is opposite to the first direction. Unless the motion detector detects the motion of the pushing mechanism moving the pushing portion in the first direction when the ejector ejects the sheet stack, the ejection controller executes interruption control of stopping the ejection of the sheet stack.
