The pressure plate 5 is lowered by the pressure plate driving motor 8 and presses the surface opposite to the pressure-sensitive adhesive layer forming surface of the long roll 91 to bring the pressure-sensitive adhesive into contact with the piece of paper and pressurize it.
Next, the pressure plate 5 is raised by the pressure plate driving motor 8, and the long sheet 91 is wound around the winding roll 2 by the width of the pressure-sensitive adhesive transferred by the winding roll driving motor 1. . The long sheet 91 is easily separated from the paper piece, and the pressure-sensitive adhesive layer on the surface of the long sheet 91 pressed by the pressure plate 5 is transferred to the paper piece, but is not pressed by the pressure plate 5. The pressure-sensitive adhesive layer on the surface 91 is not transferred but is held on the long sheet 91.
The piece of paper on which the pressure-sensitive adhesive is disposed at a predetermined position is transferred from the cradle 6 to another part by a conveying means (not shown).
If this operation is repeated as many times as necessary, a large number of paper pieces in which a pressure-sensitive adhesive is disposed at a predetermined position of the paper pieces can be obtained.
The pressure-sensitive adhesive layer on the surface of the pressed long sheet 91 is easily separated from the support, and the adhesive is arranged on a predetermined portion of the paper piece. Here, it is not necessary to protect the adhesive surface of the pressure-sensitive adhesive of the long sheet 91 and the adhesive surface of the pressure-sensitive adhesive disposed on the paper piece with a release paper or the like.

The part and amount of the pressure-sensitive adhesive of the present invention to be disposed on the paper piece are not particularly limited as long as the part and amount are sufficient to achieve the function as a book. For example, in the case of a rectangular paper piece such as A4, the pressure-sensitive adhesive is usually continuously or partially arranged in a width of about several mm along one side. Further, depending on the purpose of use such as a booklet, a pressure-sensitive adhesive may be arranged in a part of a corner so as to have a very small area, and can serve as a substitute for a staple needle. Furthermore, a pressure-sensitive adhesive having an appropriate width may be continuously or partially disposed at the center of a large piece of paper such as A3. In this case, first, a paper piece on which a pressure-sensitive adhesive is disposed is pressed and arranged, and then a whole bundle of paper pieces is folded to produce a book. In addition, after placing a pressure-sensitive adhesive layer along one side of a piece of paper and pasting it with a different piece of paper, the side facing the side of the pasted portion of the different piece of paper, and the pressure sensitive side on the back side of that side By arranging the adhesive layer, pasting it with new different paper pieces, and performing this operation as many times as necessary, it becomes a band-like object when spread, but if these paper pieces are overlapped with each other, a booklet is produced. It is also possible. Also, as a different mode, for example, a sheet of A3 paper is folded in the middle, for example, a plurality of paper sheets with adhesives arranged on the side and center of the right half are prepared, and the left side of a sheet different from the right half of one paper is prepared. A booklet can be created by pasting the halves and then pasting the left halves of different sheets and repeating that operation as many times as necessary.

After the pressure sensitive adhesive is arranged on the required number of paper pieces, the paper pieces are arranged on one side of the paper pieces by a paper piece arranging member. The means for collecting the paper pieces is not particularly limited, and an optimum means may be selected depending on the properties of the paper pieces, the number of paper pieces to be arranged, and the like.

Moreover, you may arrange these paper pieces using a flat surface with a human hand.
Since the pressure-sensitive adhesive used in the present invention has a reduced initial tack, it is not necessary to protect the adhesive surface of the pressure-sensitive adhesive disposed on the paper piece with release paper or the like.

Subsequently, the collected paper pieces are pressed on the spot or on the spot after being moved by using any transfer means, and then pressurized by a pressurizing means to produce a book. The pressurizing means is not particularly limited, and an optimum means may be selected depending on the properties of the paper pieces, the number of the prepared paper pieces, and the like. Specific examples include a means of pressing the prepared paper pieces directly or with a pressure roll through a plate, etc., and protecting the prepared paper pieces with a preventive member such as a shift and then pressing directly or through a plate. A means for pressing with a plate, a means for pressing a prepared paper piece with a pressing plate, and the like can be mentioned. Since the pressure-sensitive adhesive used in the present invention has a reduced initial tack, it is not necessary to protect the adhesive surface of the pressure-sensitive adhesive disposed on the paper piece with release paper or the like.
The pressurization condition is not limited as long as the paper pieces constituting the bundle of paper pieces can be pressed to such an extent that they can be adhered and fixed to such an extent that the function as a book can be maintained. Further, only the adhesive placement portion of the collected paper pieces may be pressurized, or the whole of the prepared paper pieces may be pressurized.

As an embodiment different from the above, after the pressure-sensitive adhesive is disposed at a predetermined position of the paper piece, a new paper piece is conveyed onto the paper piece without transferring the paper piece to another part. , Can be stacked. Next, the pressure plate 5 is lowered by the pressure plate driving motor 8 and presses the surface of the long roll 91 opposite to the pressure-sensitive adhesive layer forming surface to bring the pressure-sensitive adhesive into contact with the piece of paper. When pressed, a pressure-sensitive adhesive is disposed at a predetermined position of a new paper piece, and the stacked paper pieces are pressurized and bonded.
The same operation is repeated as many times as necessary, and after the last piece of paper is stacked, the pressure plate 5 is lowered by the pressure plate driving motor 8 and the surface of the long sheet 9 on the side opposite to the pressure-sensitive adhesive layer forming surface. And the stacked paper pieces are pressurized and bonded to obtain a book. However, at this time, control may be performed so that the pressure-sensitive adhesive is not disposed on the paper piece from the long sheet 9. For example, the cradle may be moved. Further, the stacked paper pieces may be moved by moving the front address 4. Furthermore, it may be controlled so that the long sheet 9 does not move to the take-up roll side and the pressure-sensitive adhesive is not transferred to the paper piece.
The pressure-sensitive adhesive layer on the surface of the pressed long sheet 91 is easily separated from the paper piece, and the adhesive is placed on a predetermined portion of the paper piece. Here, it is not necessary to protect the adhesive surface of the pressure-sensitive adhesive of the long sheet 91 and the adhesive surface of the pressure-sensitive adhesive disposed on the paper piece with a release paper or the like.
Furthermore, as a different embodiment, there is a simple bookbinding machine that is installed on a table and used.
