Abstract: A folding device for folding continuous paper, which is previously provided with fold lines at given intervals, along the fold lines in a zigzag pattern. The folding device comprises a feeding member of the continuous paper, a swinger fin that swings using its one end as a fulcrum like a pendulum in synchronization with the fold lines while feeding the continuous paper into its inside, and a table to be surmounted by the continuous paper that has been folded. The swinger fin includes a feed roller pair for feeding the continuous paper while sandwiching the paper therebetween, and at least a pair of guide plates facing each other with a given gap therebetween, in which the continuous paper is fed through the gap. One of the feed rollers constructing the feed roller pair and one of the guide plates, which are located on one side of the continuous paper, can be integrally opened or detached from the swinger fin.

Abstract: A sheet post-process apparatus according to one example of the present invention includes a movable stack tray for stacking a sheet that is elevated in a vertical direction; a movable tray position detection unit that detects a vertical position of the movable stack tray while a request command for post-processing of the sheet is not received; an upper surface sensor that senses either an upper surface of the movable stack tray or an upper surface of the sheet stacked on the movable stack tray when a first position of the movable stack tray detected by the movable tray position detection unit is lower than or equal to a predetermined first height; and a movable tray moving unit that moves the movable stack tray upward when either the upper surface of the movable stack tray or the upper surface of the sheet stacked on the movable stack tray is not sensed by the upper surface sensor.

Abstract: A device for laying a flexible material web 1 on a point of deposit 4 and which has at least one pair of deposit rollers 2, 3 that rotate in opposite directions. The deposit rollers 2, 3 form part of a deposit carriage 5 which is reciprocated in a reversible direction over at least the deposit length L of the material web 1. The device is more cost-effective in that the deposit carriage 5 has a smaller width than the point of deposit 4 and is reciprocated in a reversible direction over at least the deposit width B of the point of deposit 4.
