Abstract: The method for separating two successive stacks (PA. PB) of interfolded sheets comprises: once having released the formed stack (PA) on a conveyor (O), moving the two support tables (11, 12), one following another, in such a way as to fold the strip(S) of sheets hanging below the successive stack (PB) under formation supported by the pair of separator elements (14, 15), in such a way that, when the two support tables (11, 12) are brought to face one another or moved towards one another to support the successive stack (PB) under formation, an end flap (F3) of the lower sheet of the successive stack (PB) under formation is partially folded and hanging between the two support tables to form a grippable flap (L) for a facilitated extraction of the sheets from the pack (P) which is obtained once the formation of the successive stack (PB) is completed.

Abstract: A postprocessing device performs postprocessing on sheets received from an image forming apparatus. The postprocessing device includes a pair of folding rollers, a folding blade, a transport device, a drive portion, and a drive controller. The drive controller controls the drive portion to match moving speed of a tip portion of the folding blade with moving speed of a circumferential surface of the folding rollers, at a time point that the sheaf of the sheets makes contact with the circumferential surface of the folding rollers, when the image forming apparatus forms the image by ink jet printing, and to match the moving speed of the tip portion of the folding blade with the moving speed of the circumferential surface of the folding rollers, at a time point that the sheaf of the sheets reaches the nip region between the folding rollers.

Abstract: In a sheet folding apparatus for folding a sheet, a sheet is pushed at a predetermined position thereof by a push member while the sheet is being conveyed by a conveyance roller. The predetermined position of the sheet is guided to the nip section of a folding roller pair. Then, the sheet is nipped at the predetermined position thereof and folded by the folding roller pair.

Abstract: In an example, a print apparatus includes a controller and a printing unit. The controller may control the printing unit to print a media sheet with at least one indicia indicating an intended location of a fold line, wherein the media sheet is to be folded along the fold line. The controller may be to control the printing unit to print the at least one indicia to provide an offset gauge such that, when the media sheet is folded along a formed fold line, the indicia provides an indication of an offset between the intended location of the fold line and the formed fold line.
