A sheet post-processing device includes a conveying section that conveys a paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds a paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections. The controller selectively performs a ring binding mode and a direct binding mode. The ring binding mode is a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding. The direct binding mode is a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.

In a first punching mode, a control portion displaces a support member from a first-path-side end side to a second-path-side end side, and causes a first punching portion on the first-path-side end side to operate in a state where the support member has reached a first target position. In a second punching mode, the control portion displaces the support member from the second-path-side end side to the first-path-side end side, and causes a second punching portion on the second-path-side end side to operate in a state where the support member has reached a second target position. The first and second target positions are based on positions of the support member at points of time when edges on the first-path-side end side and the second-path-side end side are detected by the first sheet sensor and the second sheet sensor, respectively.

A sheet processing apparatus includes a conveying portion, a stack portion on which sheets conveyed by the conveying portion are stacked, a first regulating portion regulating a position of a sheet bundle stacked on the stack portion in a crossing direction, a second regulating portion regulating a position of a sheet bundle on the stack portion in a conveying direction, a first binding device moved in the crossing direction and binding a corner portion of a sheet bundle by a staple, a second binding device binding a corner portion of a sheet bundle without a staple, and a controller positioning the first binding device and binding a corner portion of a sheet bundle by the first binding device. The controller also moves the second binding device and binds a corner portion of a sheet bundle without a staple by the second binding device.

A machine for applying support members to opposing sides of opposing edges of a sheet material includes a support tab applicator assembly that applies a first portion of a support tab along a longitudinal edge of a first side of the sheet material, a support tab finisher assembly that applies a second portion of the support tab disposed opposite the first portion to a second side of the sheet material disposed opposite the first side, and a hole punch assembly that cuts a hole through the sheet material. The machine also may include a strengthening film applicator assembly that applies a strengthening film along a longitudinal length of the first side of the sheet material and/or across the support tab.

A method of manufacturing a hole in a component consisting of a composite material, such as a fiber or fabric reinforced plastic part, wherein the component, having first and second oppositely disposed sides, is placed with its first side on a support having an iris diaphragm. A tip which diverges in the axial direction is pressed from the second side of the component through the component, which optionally has a pre-piercing, for formation of the hole or for enlargement of the pre-piercing. The iris diaphragm has a smaller starting opening which receives a narrower region of the tip and opens into a larger opening with increasing penetration of the component by the tip, whereby the component is supported during hole formation over an as large as possible area from the first side. A piercing aid in the form of an iris diaphragm or a corresponding die button is likewise claimed.

A post-processing apparatus includes: a moving mechanism configured to move a punching apparatus in a width direction orthogonal to a transportation direction of a sheet; and a sensor configured to optically detect a mark formed on the sheet and indicating a position to be punched. The mark is configured such that an interval in the transportation direction between a plurality of feature portions extending in the width direction is configured to be changed depending on the width direction. The moving mechanism is configured to determine a position of the punching apparatus in the width direction based on a difference between respective timings of detection of the plurality of feature portions.
