This image forming system comprises: an image forming unit that forms an image on a sheet; a perforation processing unit that performs perforation processing on the sheet on which the image was formed by the image forming unit; a bookbinding processing unit that performs bookbinding processing, including binding and folding, on a plurality of sheets including the sheet subjected to perforation processing by the perforation processing unit; a square-back processing unit that performs square-back processing for forming a square-back portion on the back of a booklet bound by the bookbinding processing unit; and a display unit that, during the execution of the perforation processing and the square-back processing, presents a display prompting the insertion of a length up to a position where the perforation processing is performed from the edge of the square-back portion.

To provide a constitution for improving positional accuracy of a regulating part for regulating a projection quantity of the back of a sheet bundle from a clamp.SOLUTION: When the regulating portion moves from the initial position to the regulating position, the regulating portion abuts against the spine of the sheet bundle to regulate the amount of protrusion of the sheet bundle from the clamping position of the clamp. The adjustment unit adjusts in advance the initial position of the regulation unit with respect to the clamp position each time the square back processing is performed.SELECTED DRAWING: Figure 15

The utility model discloses a picture album spine forming device, which relates to the technical field of picture album processing and comprises a forming table and an adjusting component, the bottom of the forming table is connected with a base, and the adjusting component used for limiting spines of different sizes on a book case is arranged at the upper end of the forming table. And the two adjusting assemblies are symmetrically arranged about the vertical central axis of the forming table, each adjusting assembly comprises an adjusting groove, a supporting frame, a sliding block and an extension plate, the supporting frames are slidably arranged in the adjusting grooves, the sliding blocks are arranged at the bottoms of the supporting frames, and the extension plates are connected to the side edges of the supporting frames. According to the picture album spine forming device, the middle of the forming table is used for containing a picture album spine, the triangular supporting frame slides in the adjusting groove according to the width needed by the different picture album spines to adjust the position, the device can conduct forming machining on the picture album spines of different sizes, sliding blocks and the adjusting groove are distributed in a staggered mode, and the sliding smoothness is improved; and the extension plate provides a placement surface for the book shell of the picture album.

The present invention aims to provide a device that allows for easy setting of perforation at desired locations when performing corner processing and perforation processing on a folded sheet bundle. [Solution] When performing corner back processing and perforation processing on a folded sheet bundle, the presence or absence of corner back processing is input, the starting position of the perforation processing is predetermined, and then the distance to the perforation processing position is input, thereby enabling perforation at the intended location without causing positional shift due to corner back processing.

A back processing section C2 performs back processing to press a ridge portion of a sheet bundle sandwiched between an upper jig unit 121 and a lower jig unit 120 by a pressing roller 123 so that the ridge portion of the sheet bundle protrudes downstream with respect to the upper jig unit 121 and the lower jig unit 120. The saddle controller is capable of executing a mode in which, in a state in which nip by the upper jig unit 121 and the lower jig unit 120 on the bundle of sheets undergoing the back treatment by the back treatment section C2 is released, the bundle of sheets undergoing the back treatment is conveyed downstream in a conveyance direction by a saddle third roller pair 118, and in which the bundle of sheets undergoing the back treatment by the back treatment section C2 is conveyed downstream in the conveyance direction by the saddle third roller pair 118. And performing the back processing again on the sheet bundle by the back processing portion C2.

A notching device (1) for binding machines (2), suitable for automatically creating on the back (D) of blocks (B) of sheets (5) a plurality of notches (T) intended to collect an adhesive for gluing a cover. The notching device (1) comprises a plate (8) defining a main axis (V) and having an upper face (9) facing the back (D) to be engraved and one or more engraving tools (13) which can be anchored to the upper face (9) to make notches (T) on the back (D) by rotating the plate (8). Each engraving tool (13) comprises a body (14) with an end (15) provided with a cutting edge (16) which comprises a first cutting portion (18) having a shape complementary to the notch (T) to be made and second cutting portions (19A, 19B) adjacent to and placed on the sides of the first portion (18) to trim the back (D) and remove the excess material generated by the first portion (18), and wherein the second cutting portions (19A, 19B) are substantially aligned and parallel to the upper face (9).

The utility model provides rounding and ridging equipment, which is used for rounding book blocks and comprises a fixed plate, a movable plate, a driving part and a forming part. The movable plate and the fixed plate are arranged in parallel, and the movable plate can move relative to the fixed plate in the direction perpendicular to the fixed plate. The driving part drives the movable plate to be close to or far away from the fixed plate so as to clamp the book block between the fixed plate and the movable plate or release the book block. And the spine position of the book block extends out of the range of the fixed plate and the movable plate. And the forming part is controlled to apply pressure to the edge of the spine, so that the spine is formed into an outwards convex arc shape. The embodiment of the utility model is not limited by the specification of the book block, and can be suitable for book blocks with different sizes or thicknesses. After the book block is fixed by the fixed plate and the movable plate, the pressure applied by the forming part acts on the edge of the spine, the influence of the thickness of the book block is small, and the application range of the rounding and ridging equipment can be further widened.
