摘要： A sheet separation device (1) separates a non-bonding portion (B) of a two-ply sheet (PJ) in which two sheets (PI, P2) are overlapped and bonded together at one end (A) of the two-ply sheet (PJ). The sheet separation device (1) includes a separator (16, 17) that includes a first separator (16) and a second separator (17). The first separator (16) is inserted into a gap (C) between the two sheets (PI, P2) of the two-ply sheet (PJ). The second separator (17) is inserted between the two sheets (PI, P2) at another end (B) of the two-ply sheet (PJ) opposite to the one end (A) of the two-ply sheet (PJ) and moves in a width direction of the two-ply sheet (PJ), after the first separator (16) is inserted into the gap (C) and relatively moves from the one end (A) to said another end (B).

摘要： A sheet processing apparatus (100) is configured to sandwich one or more sheet media in a two-ply sheet in which two sheets are overlaid and bonded together at a portion of the two-ply sheet. The sheet processing apparatus includes a controller (500) configured to control insertion processing to insert the one or more sheet media into the two-ply sheet based on a length of the two-ply sheet in a conveyance direction, a length of one of the one or more sheet media in the conveyance direction, and a number of the one or more sheet media.

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).
摘要翻译：折页装置（1）包括：折叠部分形成单元（12,13），其通过将形成在片材（P）的一部分上的弯曲部分夹在上游第一片材（P）之间而在片材（P）上形成折叠部分输送单元（11）和下游第二纸张传送单元（13,14），通过由第一纸张传送单元（11）保持片材（P）的一部分并向纸张（P）施加输送力以使纸张（P）在第二纸张传送单元（13,14）的上游; 以及设置在与第二纸张传送单元（13,14）的大致相同位置的下方的纸张前端检测单元（22）。纸张（P）基于纸张前端检测单元（22）的检测定时被输送，使得纸张（P）的前端从第二纸张传送单元（13,14）突出预定的突出量，在将输送力施加到片材（P）之前立即倒转片材（P）。
