An image forming system includes an image forming apparatus, a pressure sealing processing apparatus, and a control unit. The control unit is configured to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a grammage is smaller than a predetermined grammage, and is configured not to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a grammage is equal to or more than the predetermined grammage.

This stretch function-added loading sheet is provided with one sheet body and a force crimping unit. The force crimping unit comprises two clamping block plates and one clamping jig, and on one surface of the sheet body, the two clamping block plates are fixed on both sides of a folding centerline on the sheet body. In a state in which the sheet body is folded along the folding centerline such that the two clamping block plates overlap each other with the sheet body on the inside, the clamping jig is fixed to the two clamping block plates so as to clamp the two clamping block plates. The stretch function-added loading sheet has a stretch function with which the sheet body stretches by the clamping jig opening through application of a tensile force perpendicular to the folding centerline to the sheet body, and shrinks when said tensile force is reduced.

A binder forming a booklet by bundling end portions of a plurality of sheets of paper such that paper addition or removal is possible includes a spread-shaped front cover member configured for sandwiching a bundle of the plurality of sheets of paper, a long cover member having an opening portion along a back portion of the front cover member, and a plurality of clips arranged so as to be configured for moving forward and backward in the opening portion of the cover member and having a pair of holding pieces and claw portions respectively extending inward from tips of the holding pieces. Through holes through which the claw portions of the plurality of clips are respectively inserted are formed in each of front and back covers of the front cover member.

Disclosed herein is a binder clip. The binder clip includes: a body formed by integrating an elastic plate and clamping surfaces with one another, and provided with fastening portions; first and second grips each coupled to both sides of each of the clamping surfaces of the body, and configured to open the fastening portions; first and second rotatable hinges rotatably disposed around ends of the first and second grips; first and second supports each coupled and fastened to a corresponding one of the first and second rotatable hinges, and configured to have a round bar shape and a same torque; and a socket provided with a connection hole configured such that second ends of the first and second supports are fastened into both sides thereof and are connected to the socket, and configured to have the same torque and rotational threads on the inner surface of the connection hole.

A method for bringing together a wrapper and a plurality of inserts can be used to form an advertising means compilation. In a region of a compilation section, the wrapper and the inserts are deposited on one another individually and in succession on a conveying element which is moved in a direction of transport. A leading edge of the wrapper is deposited offset relative to leading edges of the inserts so as to form an excess length of the wrapper. The inserts are deposited on one another, forming a stack, such that the leading edges of the inserts form a common fold edge. The excess length of the wrapper, which lies flat on the conveying element or on the stack of inserts, is folded around the fold edge and, at least in part, around the stack of inserts so as to form the advertising means compilation.
