    • It is aimed to provide a folding device and a folding method capable of precisely folding a sheet even in the case of changing a thickness of the sheet or a tension applied to the sheet. A folding device includes a folding mechanism configured to form a first folding line (B1) extending from one widthwise end of a sheet (S1), a second folding line (B2) extending obliquely from the other widthwise end (S12) of the sheet (S1) toward an end of the first folding line (B1) and a third folding line (B3) configured to reverse one widthwise part of the sheet (S1) such that one widthwise part of the sheet (S1) folded along the second folding line (B2) overlaps with another part. The folding mechanism includes a second folding member (11) having a second folding line forming portion (19a) configured to form the second folding line (B2). The second folding member (11) is so attached to a conveying mechanism (2) that the second folding line forming portion (19a) is movable with respect to the formation positions of the first folding line (B1) and the third folding line (B3).
    • 目的在于提供即使在改变片材的厚度或施加到片材上的张力的情况下也能够精确地折叠片材的折叠装置和折叠方法。 折叠装置包括折叠机构,该折叠机构构造成形成从片材的一个宽度方向端延伸的第一折叠线(B1),从片材的另一宽度方向端部(S12)倾斜延伸的第二折叠线(B2) S1)朝向第一折叠线(B1)的端部;以及第三折叠线(B3),其构造成使片材(S1)的宽度方向的一部分反转,使得沿着第二折叠线折叠的片材(S1)的一个宽度方向部分 (B2)与另一部分重叠。 折叠机构包括具有构造成形成第二折叠线(B2)的第二折叠线形成部分(19a)的第二折叠构件(11)。 第二折叠构件(11)附接到输送机构(2),第二折叠线形成部分(19a)可相对于第一折叠线(B1)和第三折叠线(B3)的形成位置移动 )。

    • There is a need to provide a sheet post-processing apparatus capable of neatly squaring a booklet spine without any damage such as a wrinkle on the spine and an image forming apparatus having the sheet post-processing apparatus.
      According to the sheet post-processing apparatus, a drive motor(SM9) drives first and second pressing members(650,651). A circumferential velocity(V1,V2) of the pressing member(650,651) on a pressing surface pressed against the booklet(2a) spine(2a1) is configured to be reverse to a moving velocity(W) of a moving portion(656a), and to be greater than the moving velocity(W).
    • 需要提供一种能够在没有诸如脊柱上的皱纹之类的任何损伤的情况下使书册脊柱整齐地平整的片材后处理装置以及具有片材后处理装置的图像形成装置。 根据片材后处理装置,驱动马达(SM9)驱动第一和第二按压构件(650,651)。 按压小册子(2a)书脊(2a1)的按压表面上的按压构件(650,651)的圆周速度(V1,V2)被配置为与移动部分(656a)的移动速度(W)相反, 并大于移动速度(W)。
