The adhesive width 3 of the adhesive 3 must be adjusted by peeling off the adhesive 3 each time the change occurs. Therefore, the adhesive width Z of the adhesive 3 must be adjusted each time according to the thickness T of the text 4. There is the hassle of having to do it. In particular, there are many bound copies,
Moreover, when the thickness T of the text 4 is different, there is a problem to be improved in the workability of bookbinding.

Further, in the bookbinding apparatus disclosed in Japanese Utility Model Publication No. 56-3182, the thickness T of the text 4 is constant, and bookbinding is performed using the cover for exclusive use of the text 4 having the constant thickness T. Therefore, there is a problem that it is not possible to correspond to all the thicknesses T of the text 4 with respect to the sticking width Z of the adhesive 3 and the size of the cover.

In order to correspond to all the thicknesses T in the text 4, it is necessary to prepare many kinds of covers, which is not practical. In actual bookbinding, the covers are inclined at a predetermined angle. The cover with the text 4 placed on the rear wall is supported so that it is supported, and the spacer plate is interposed between the covers 1 and 2 and the text 4 so that the back plate is pressed against the rear wall with the spacer plate. The front cover 1 and the front cover 2 are held, and then the adhesive 3 is melted by electric heating to bond the body 4 to the cover. It is necessary to pre-bend it into the shape of a letter. Therefore, every time the thickness T of the text 4 changes, the covers 1 and 2 have to be bent in accordance with the thickness T of the text 4, which requires a considerable amount of time for bookbinding,
When the number of copies is large and the thickness of the text is large, there is a problem in bookbinding workability.

Next, in the one disclosed in JP-B-44-23444, a holding frame and a holding plate for holding the main body 4 are attached to the endless chain, and the main body 4 is sandwiched. The back of the text 4 is pulled back with a backing piece, and then the back is roughened by the spine and creasing parts, and then the text 4 of the covers 1 and 2 stretched flat is attached. In order to perform a series of steps in which a crease is made on the part to be glued and the crease is glued, and then the glued part and the spine of the body 4 having a rough surface are pressure-bonded and sequentially carried out, the device itself is used. Is not suitable for ordinary office equipment.

In addition, Japanese Utility Model Publication No. 44-3610 discloses a technique in which a body is sandwiched by a sandwiching plate, and the back portion of the sandwiched body 4 is pressed by a pressing plate to shift the back of the body. , The backing pressing plate disclosed here moves only in the horizontal direction in the same plane as the lower end of the back of the text and presses the back of the text, so that the back of the text is folded like a cover. It cannot be pressed. Therefore, in order to shift the back of the text with this pressing plate, it is effective only as a pre-process of adhering the spine of the text to the cover, and during the bookbinding process, the spine of the text and the attachment of the spine of the text to the cover are adhered. There is a problem that the process becomes necessary and the apparatus becomes large-scale as described above.

The present invention omits the adjustment of the adhesive sticking width according to the thickness of the text, automatically determines the size of the cover sheet according to the thickness of the text and cuts it, and The present invention provides a bookbinding method and an apparatus thereof that can be used as office equipment by simplifying the bookbinding process by simultaneously performing the alignment and the adhesion of the body and the cover.

In the invention of the method of the present invention, since it is constructed in this way, it has the following effects. That is, an adhesive for adhering the text to the cover is placed at a position matching the size of the text, and the cover attached along the inside of the spine of the cover is separated by the edge of the adhesive. And bend it at a right angle,
The cover on the side without the adhesive is set up along the back plate, and the cover on the side with the adhesive is placed almost flush with the cutter sheet. , The cover that is folded at a right angle with the edge of the adhesive as the boundary is the size of the text, and because it is folded with the edge of the adhesive as the boundary, it may be folded regardless of the adhesive width. it can. Then, by placing the cover sheet on the cover sheet folding plate and the cutter sheet that are flush with each other, it is possible to prepare for the next step of cutting the cover sheet, and it is possible to make the adhesive flat. It will be possible.

Next, the text is set along the cover that is erected along the back plate, and the lower end thereof is placed on the adhesive, whereby the cover is folded at the edge of the adhesive. In addition, since the adhesive is flat, the lower end of the text can be placed on the adhesive so that the lower end of the text uniformly contacts the adhesive without being displaced.

Next, by moving the body presser and fixing the body by pressing the body on the cover standing along the back plate, the cover on the side where the adhesive is attached is opened,
It becomes possible to sandwich the text between the cover supported by the back plate and the text retainer. Also, the melted adhesive is melted by pressing the part slightly separated from the spine of the text against the cover held on the back plate by the text presser, so that the melted adhesive is applied to the paper on the spine of the text. It becomes possible to penetrate between.

Next, when the cover folding plate is lifted up, the cover is on the cover folding plate in the opened state, so that the edge of the cover placed on the cover folding plate hangs down and the cover folding plate The cover is lifted between the tip and the corner of the spine of the body being pressed by the body retainer, and then the cover folding plate is moved forward, so that the lifted cover portion is pushed by the tip of the cover folding plate. Thus, it becomes possible to fold along the lower end of the body where the adhesive has penetrated, along with the excess adhesive that is stuck in a molten state on the cover.

By this bending, it is possible to press the bent portion against the lower end of the text while the text is back-to-back, and to bond the front cover and the text and to close the text at the same time. Also, since the excess adhesive attached to the cover is folded along with the cover on the cover folding plate, the adhesive can be folded regardless of the thickness of the text without adjusting the adhesive attachment width according to the thickness of the text. It will be possible.

In another invention of the method, after the body is pressed by the body retainer, the end of the cover sheet on the cutter sheet is cut by a cutter movably provided at the edge of the body retainer. Thus, it becomes possible to cut the cover sheet at a position suitable for the size of the text corresponding to the thickness of the text. When the cover fold plate is lifted after cutting the cover in this way, the cover is on the cover fold plate in the open state, so the cut edge of the cover placed on the cover fold plate hangs down. , The top of the cover folding plate is lifted between the tip of the cover and the corner of the spine of the body pressed by the body retainer, and then the cover folding plate is moved forward to cover the folded cover.
