Abstract

PROBLEM TO BE SOLVED: To provide a binding method for a saddle stitched book, which has comparatively few pages such as about twenty pages or less and is efficiently bound by a pasting system at a low cost. SOLUTION: A sheet 2 having printing surfaces by four pages on obverse and reverse and at right and left is printed with a printing machine. Respective sheets are gathered by a gathering machine 1, successively fed out of the delivery port of the gathering machine in the order of numbers of pages without overlapping and leaving intervals therebetween. Next, the respective sheets are transferred so as to provide a chevron folding ridge 3 along a feeding-out direction at the middle between pages. During the transferring of the respective sheets, paste 16 is applied on the folds 3 of the respective sheets. Finally, by successively gathering the respective sheets on a saddle, a saddle stitching is realized through the pastes applied on the respective sheets.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle stitcher for binding sheets, which are collated in a page order by a collating machine, by a glue binding method without using wires. The present invention relates to a bookbinding method. 2. Description of the Related Art Conventionally, saddle stitching is a method in which a plurality of sheets are folded in a chevron shape, and the folded line portions of the stacked sheets are stapled with a wire in a hook shape. However, the binding method using a wire has a problem that the tip of the wire is opened and the finger is injured. For example, recently, for example, JP-A-60-109900, JP-A-2000-4
As known from Japanese Patent No. 3445 or the like, saddle stitching by glue binding, in which the fold line portion of each sheet, that is, the spine portion, is bonded to each other with glue, has been performed. [0003] In the saddle stitching by this glue binding method, a large number of sheets are adhered to each other with glue, so that the danger as in the case of the wire binding method is eliminated. And the advantage that no incombustible substances are emitted at the time of disposal. In the conventional saddle stitching method, in the case of the binding method using wire, a plurality of pages of a desired size are printed at predetermined locations on one large sheet of paper, and then the large sheet of paper is printed. Fold it to the size of each page, align it so that a folding line is provided in the center of each page, overlap each other set of pages obtained in the same way on the folding line and bind them with wire, After the pages are bound, the top and bottom and the fore-edge of each page are cut to cut and remove the fold portions of each page. [0005] On the other hand, in the saddle stitching method, in the case of the glue stitching method, a plurality of pages of a target size are printed at a predetermined position on one large sheet of paper. The same, but after printing, 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 each page in a predetermined direction, and And a step of bonding them with glue. 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 bookbinding apparatus is capable of binding a plurality of sheets on one large sheet. That the pages of the intended size are printed, and that means for continuously applying glue to predetermined portions of the large paper on which the plurality of pages are printed are provided. It is necessary to provide a means for folding the paper into a predetermined number of pages after the application and bonding each page. As described above, the conventionally known saddle stitching machine is conceived from a method of folding large paper on which a plurality of pages are printed, so that the number of pages such as a weekly magazine is increased to 30 or more. It can be said that the bookbinding apparatus is suitable for binding a wide range of booklets. However, when binding a booklet having a small number of pages of about 15 or 6 pages or less, such as a catalog or a company guide, the bookbinding apparatus is used as described above. Because it is equipped with various means, it is too large, and it is possible to lower the price originally.However, in order to bind a booklet with a small number of pages with a large device, the unit price of bookbinding is inevitable. There was a problem that it had to be high. SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the saddle stitching in the related art, and efficiently converts a thin booklet having a small number of pages by a glue binding method. ,
Further, it is an object of the present invention to provide a saddle stitch bookbinding method capable of binding at a low price. [0009] The present invention, as a specific means for that,
This is a saddle stitching method of binding each sheet collated by a collating machine by a glue binding method, wherein the collated sheets overlap each other from a discharge port of the collating machine according to a page order. Instead, the sheets are sequentially sent out at intervals, and then each sheet sent out from the collating machine is transferred in the sending direction such that a mountain-shaped crease is provided at the center between pages in the feeding direction. On the way, glue is applied to the folding line of each sheet, and each of the mountain-shaped sheets coated with the glue on the folding line are sequentially accumulated on the saddle, and each sheet is applied by the applied glue. Is saddle-stitched. [0010] In this saddle stitching method, one small sheet of about four pages is printed by a printing machine, and one sheet is printed on a predetermined page from a collating machine. The sheets are sent out in order, with the sheets not being overlapped with each other and being sent out at intervals when each sheet is sent out of the collating machine. 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.
