Abstract

First document/image data is printed onto a sequence of sheets that includes sheets of a given size, and sheet(s) of a size that in at least one dimension is larger than the sheets of the given size. At the same time the first document/image data is being printed, second document/image data, i.e., foldout data, is printed onto the outer margin, i.e., a foldout portion, of the sheet(s) of the larger size. The larger-size, foldout sheet(s) is then folded so as to be creased near its overlap with the given-size sheets, and is collated into the sequence of the given-size sheets to form a bundle that is then bound. Thereafter trimming to size the non-bound edge(s) of the bundle slices away the crease in the foldout sheet, leaving the foldout cut-away as an insert tucked into the booklet.

Claims12

Dependent claims

In an image-forming system, a bookbinding method for collating printed sheets into bundles and binding together the sheet edges along the bundle spine portion, the bookbinding method comprising:

an image-forming step of sequentially forming, based on predetermined image data, images onto a series of sheets;
a fold-process step of folding sheets on which images have been formed in said image-forming step;
a stacking step of collating into bundles sheets on which images have been formed in said image-forming step and/or sheets folded in said fold-process step;
a bookbinding step of binding together spine-portion edges of sheet bundles collated in said stacking step;
and
a trimming step of trimming true at least the fore-edge of the sheet bundles bound in said bookbinding step;
wherein
in said image-forming step, on at least a single sheet of the sequential series of sheets on which images are formed, a foldout-image area is preestablished along the sheet's fore-edge portion, and imaging is carried out on the foldout-image area;
in said fold-process step, the foldout-image area is fold-processed along a folding-back fold location;
and
in said trim-finishing step, said fold location is cut to thereby isolate the foldout-image area, tucked into the sheet bundle.

8 more elements

An image-forming system comprising:

a data processor having a series of image data and at least one folding-image data;
image-forming means for forming an image on a sheet based on predetermined image data from the data processor;
sheet folding means for folding a sheet conveyed from the image-forming means;
stacking means for collating and stacking sheets conveyed from the sheet folding means or the image-forming means;
binding means for binding a spine edge of a sheet bundle conveyed from the stacking means;
trimming means for trimming true at least a fore-edge portion of the sheet bundle bound by the binding means;
and
control means for controlling the image-forming means, folding means and trimming means;
wherein
the control means is configured
(a) to control the image-forming means to sequentially form images on sheets based on the series of image data and to form images of at least one selected image data on the same sheet in parallel to the folding-image data;
(b) to control the sheet folding means to fold, at a folding-back fold location, the sheet formed with the a foldout image;
and at the folding step, the foldout-image area is folded at a folding-back fold location;
and
(c) to control the trimming means to trim at a position to cut free the folding position.
