摘要： A conveyed-material separation device (100) includes an air jetting unit (2A to 2C) and a retaining unit (3A to 3F). The air jetting unit jets air to stacked conveyed materials to float an end of a conveyed material. The retaining unit (3A to 3F) retains and separates the conveyed material floated by the air jetting unit (2A to 2C). A position of the retaining unit is changeable according to a width dimension of the conveyed material in a width direction perpendicular to a floating direction of the conveyed material.

摘要： A sheet separation device (1) separates a non-bonding portion (B) of a two-ply sheet (PJ) in which two sheets (P1, P2) are overlapped and bonded together at one end (A) as a bonding portion (A) of the two-ply sheet (PJ). The sheet separation device (1) includes two branched conveyance paths (K4, K5) and a separator (16). The two branched conveyance paths (K4, K5) are branched in different directions. The separator (16) is configured to be inserted into a gap (C) formed between the two sheets (P1, P2) of the two-ply sheet (PJ), separate the two sheets (P1, P2), and guide the two sheets (P1, P2) to the two branched conveyance paths (K4, K5), respectively.

摘要： A sheet separation device (100) to separate a two-ply sheet in which two sheets are bonded together at a portion of the two-ply sheet includes a rotator (109), a conveyor (113) configured to convey the two-ply sheet to the rotator (109), and means for winding (110,111,112,T1,T2; 117; 119), around the rotator (109), the two-ply sheet conveyed by the conveyor (113), to create a difference in winding circumferential length between the two sheets and separate the two sheets. The conveyor (113) conveys the two-ply sheet with a bonded portion of the two-ply sheet being an upstream end or a downstream end of the two-ply sheet in a conveyance direction of the two-ply sheet.

摘要： A sheet folding apparatus (1) includes: a folded part forming unit (12, 13) that forms a folded part on the sheet (P) by nipping a curved portion formed on a part of the sheet (P) between an upstream first sheet conveying unit (11) and a downstream second sheet conveying unit (13, 14) by holding a part of the sheet (P) by the first sheet conveying unit (11) and applying conveying force to the sheet (P) to reverse the sheet (P) upstream by the second sheet conveying unit (13, 14); and a sheet leading end detection unit (22) disposed downstream of or at almost same position as the second sheet conveying unit (13, 14). The sheet (P) is conveyed based on a detection timing of the sheet leading end detection unit (22) such that the leading end of the sheet (P) protrudes by a predetermined protrusion amount from the second sheet conveying unit (13, 14) immediately before applying conveying force to the sheet (P) to reverse the sheet (P).
