TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle stitching method for binding sheets in a page order by a binding machine by a glue binding method without using wires.
[0002]
[Prior art]
In the conventional saddle stitching, a method of bending a plurality of sheets into a chevron shape and binding the folds of these stacked sheets to each other in a hook shape with a wire has been widely performed. The binding method has a problem that the tip of the wire is opened and the finger is injured. Recently, for example, as described in JP-A-60-109900 and JP-A-2000-43445, each sheet 2. Description of the Related Art Saddle stitching based on the glue binding method of bonding the fold line portions of paper, that is, the spine portions to each other with glue has been performed.
[0003]
[Problems to be solved by the invention]
The saddle stitching method using the glue binding method has an advantage that a large number of sheets are adhered to each other with glue, thereby eliminating the danger of the wire binding method and eliminating incombustible materials at the time of disposal. It has the advantage of not emitting.
[0004]
Among the conventional saddle stitching methods, in the case of the wire binding method, a plurality of pages of a desired size are printed at a predetermined location on one large sheet of paper, and then the large sheet is printed on each page. Folded to the size, aligned so that a folding line is provided at the center of each page, another set of pages obtained in the same way are overlapped on each other on the folding line and bound by wire, and each page is bound After that, the top and bottom and the fore-edge of each page are cut, and the creases of each page are cut and removed.
[0005]
On the other hand, in the saddle stitching method, in the case of the glue binding method, the same as the wire binding method until a plurality of pages of a target size are printed at predetermined positions on one large sheet of paper. However, after printing, at a stage before folding this large paper to the size of each page, a step of applying glue to the fold portion of each predetermined page in advance, folding in a predetermined direction, and gluing each page with glue Bonding step is required.
[0006]
As described above, in the conventional saddle stitching method, in both the case of the wire binding method and the case of the glue binding method, the binding apparatus is capable of binding a plurality of sheets on a single large sheet with a plurality of objects. The size of the printed page is printed, and means for continuously applying paste to a predetermined portion of the large paper on which the plurality of pages are printed are provided. It is necessary that the paper be provided with means for folding the paper into a predetermined number of pages and bonding each page.
[0007]
As described above, since the conventionally known saddle stitching machine is conceived from a method of folding large paper on which a plurality of pages are printed, the number of pages such as a weekly magazine reaches 30 or more. Although it can be said that the bookbinding apparatus is suitable for binding a booklet, when a booklet having a small number of pages of about 15 or 6 pages or less, such as a catalog or a company guide, is bound, the bookbinding apparatus may use the various types of books described above. Because it is equipped with means, it is too large and it can be cheaper than it should be, but the unit price of bookbinding has to be high for bookbinding with a small number of pages by a large device There was a problem that it was not obtained.
[0008]
[Means for Solving the Problems]
The present invention solves the above-mentioned problems of saddle stitching in the related art, so that a thin booklet with a small number of pages can be efficiently and cheaply bound by a glue stapling method. The purpose of the present invention is to provide a saddle stitching method.
[0009]
The present invention provides, as a specific means, a saddle stitching method for binding each sheet collated by a collating machine by a glue binding method, wherein each collated sheet is page-ordered. The sheets are sent out at intervals from each other without overlapping each other from the discharge port of the collating machine in accordance with the following formula. Is provided so that glue is applied on the folding line of each sheet in the middle of the transfer, and each mountain-shaped sheet with the glue applied on the folding line is sequentially accumulated on the saddle. Further, each sheet is saddle-stitched with the applied glue.
[0010]
In this saddle stitching method, each small sheet of about four pages is printed by a printing machine on the front, back, left, and right sides, and these sheets are sent out from a collating machine in a predetermined page order. However, at this time, when each sheet is fed from the collating machine, the sheets are not overlapped with each other and are sent at an interval. As a result, in the course of the transfer, each of the fed sheets is surely formed with a crease in the shape of a chevron at the center between the pages along the feed direction one by one by the crease forming means, and then transferred. Glue is accurately applied to the chevron creases of each sheet, and the glued sheets are glued together in the final butting process on the saddle. Can be.
