Description

The present invention relates to a method of manufacturing a paper sheet stack, and more particularly, notebook, notepad, etc., easy to manipulate turn one by one be of paper stapled state from the front and back both directions paper The present invention relates to a method for producing a laminated body .

  In general, paper sheet laminates such as notebooks and notepads are bound in a state where sheets of the same size are bundled into a single volume with their outer edges aligned. In such a paper sheet laminate, the paper can be turned one by one by moving it in the turning direction with the fingertip hung on the outer edge of the paper on the fore edge side. In practice, however, the bound sheets of paper can be rolled up multiple times at a time because their outer edges are aligned exactly in the thickness direction. There are many cases where this is not possible.

  So, for example, by cutting the outer edge of the paper on the fore edge side of the memo pad in a state shifted in the thickness direction and bundling the paper, binding the fingertips on the outer edge of the paper makes it easier to pick up the paper one by one Has been proposed (see, for example, Patent Document 1).

JP-A-11-334252

  However, in the configuration disclosed in Patent Document 1, since the outer edge on the back side coincides with the thickness direction, the outer edge of the paper on the fore edge side is shifted along the thickness direction. There is an inconvenience that the difference between the flat areas of the uppermost sheet and the lowermost sheet becomes large and the effective area for writing or the like becomes large or small.

  In addition, the laminated article of Patent Document 1 is only guaranteed to be rolled from either the front or back direction. For example, when it is easy to roll from the front side, it is difficult to roll from the back side. Inconvenience. In this case, if the punching process or the like for forming the cutout portion is performed from the front and back sides, it is possible to secure the ease of turning the paper from both the front and back sides, and it is possible to eliminate the difference in the flat area of each paper. It becomes.

  However, in this case, the number of man-hours for forming the notch is at least twice, resulting in a disadvantage that the manufacturing process becomes complicated.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and the object of the present invention is to simplify the manufacturing process, in particular, the process of forming the notch, and it can be used in both directions. An object of the present invention is to provide an easy-to-use method for producing a paper sheet laminate.

In order to achieve the above object, the method for producing a paper sheet laminate according to the present invention includes stacking the paper sheets so that two outer edges of the outer edges of a plurality of paper sheets are aligned, and an initial laminated state. age,
Shifting at least one outer edge of the laminated paper sheets excluding the two opposite outer edges in the plane direction;
On one outer edge of the two outer edges, a punching process is performed along the direction perpendicular to the plane of the paper sheet to form a notch,
Return the paper sheets to the initial laminated state,
After aligning the outer edges of the paper sheets, by forming a back portion on the other outer edge excluding the outer edge on which the notched portion is formed, a technique is adopted in which the deviation of the notched edge is exposed on each side of the front and back surfaces. Yes.

  The paper sheets in the method have a strip shape that can produce a plurality of paper sheet laminates, and a plurality of paper sheets are formed by cutting the cut-out portions after forming the cut-out portions in an area corresponding to each book. Can be used at the same time.

  In the present invention, the “paper sheet laminate” includes a notebook, a memo pad, a book, a report paper, a notebook, a book, a sample book, and the like in which a large number of sheets or sheets are stacked and bound.

According to the present invention, since the notch edge of the notch is configured to appear on each side of the front and back surfaces in a state shifted along the surface of the paper sheet, for example, when a paper sheet laminate such as a notebook, It is possible to selectively turn the operation from both the front side and the back side.
In addition, by providing a concave portion between the front side turning region and the back side turning region, a region where the fingertip is hooked on the notch edge is secured, and the ease of turning can be secured.
Furthermore, since the notch can be formed by a single punching process or the like, the number of manufacturing steps can be minimized and the manufacturing cost can be reduced.
Furthermore, since a plurality of paper sheet laminates can be manufactured at the same time, combined with the formation of notches by a single punching process, the manufacturing efficiency is further improved.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic perspective view according to an embodiment in which the paper sheet laminate of the present invention is applied to a notebook. In this figure, a notebook 10 has a back cloth 11 constituting a back part attached to one end side in a state where a large number of paper sheets P as paper sheets are laminated, whereby each paper sheet P is integrated into one piece. It is bundled into a book.

  The sheet P includes a back outer edge 13 to which the back cross 11 is attached, an upper outer edge 15 and a lower outer edge 16 that are continuous with the back outer edge 13 and are oriented in a direction substantially orthogonal to the back outer edge 13, and the upper outer edge 15. And it is provided in the shape provided with the front outer edge 18 which is located in parallel with the said back outer edge 13 and which comprises the lower outer edge 16 and comprises a front edge.

  A cutout 20 is formed in the front outer edge 18. The notch 20 is formed by performing a punching process once using a press device provided with a cutting blade whose cutting edge is substantially U-shaped or U-shaped. Here, in the notch portion 20, a notch edge 20 </ b> A along a U-shaped or U-shaped trajectory appears on the front outer edge 18 of each sheet P.

  That is, the cutout portion 20 has a state in which the cutout edge 20A is slightly shifted along the surface direction of the paper P in the thickness direction of the paper P, and the cutout edges 20A are formed on the front and back surfaces of the notebook 10. Thus, as shown in FIG. 2, the front side turning region 22 and the back side turning region 23 are symmetrically positioned in two upper and lower regions along the front outer edge 18. Here, between the front side turning area 22 and the back side turning area 23, one concave portion 24 is formed to keep the respective turning regions 22, 23 discontinuously. The fingertip is easily hooked on the P cutout edge 20A.

  Next, a method for manufacturing the notebook 10 will be described with reference to FIGS.

  As shown in FIGS. 3A and 3B, a strip-shaped paper PL that can produce a plurality of notebooks is used, and two outer edges P1 and P2 of the strip-shaped paper PL are substantially opposite to each other. The matching state is set substantially horizontally as the initial laminated state, and the outer edge P3 on one end side in the longitudinal direction is sandwiched by the clamp 30 and temporarily fixed.

  Next, as shown in FIGS. 4A and 4B, the outer edge P4 of the strip-shaped paper PL that is opposite to the side on which the clamp 30 is located by displacing the clamp 30 with respect to the horizontal plane is The state which shifted | deviated along the surface direction of is formed. In this state, as shown in FIG. 4B, the outer edge P4 is inclined in the thickness direction.

  Then, the cutting blade 31 is lowered from above, and a notch 20 is formed in the outer edge P2 on one end side in the width direction that is continuous in a direction substantially orthogonal to the outer edge P4 (see FIG. 4C).

  Thereafter, as shown in FIG. 5A, the entire belt-like sheet PL is returned to the initial state so as to be substantially horizontal. As a result, the notch edge 20A of the notch 20 is displaced corresponding to the amount of displacement formed on the outer edge P4 on the one end side in the longitudinal direction described above, and the deviation appears on both the front and back sides of the belt-like sheet PL. Become.

  Then, the immediate inner side of the clamp 30 is cut by a cutting device (not shown), and the back cross 11 is attached to the outer edge P1 opposite to the outer edge P2 where the notch portion 20 is formed. Accordingly, three notebooks 10 are formed by cutting the notch portions 20 along the dotted lines in the figure.

  The notebook 10 configured as described above has the paper P one by one from the front side by placing the fingertip on the notch edge 20A of the front side turning area 22 when the paper P shown in FIG. On the other hand, when the notebook 10 is turned upside down, the sheet P can be turned one by one by placing the fingertip on the cut edge 20A of the back side turning area 22.

  Therefore, according to such an embodiment, the notch that can be turned from both the front and back sides of the notebook 10 by performing the punching process when forming the notch 20 in the single notebook 10 only once. The edge 20A can be exposed, and the effective area of writing on each paper P can be kept the same.

Although the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, the present invention is not limited to this.

  For example, in the above embodiment, the case where three notebooks 10 are manufactured has been described. However, the present invention is not limited to this, and the number of books manufactured simultaneously can be increased or decreased as necessary. . Moreover, the shape of the notch 20 is not limited to a U-shape or a U-shape, and can be provided in an arbitrary planar shape. The formation position of the notch 20 is not limited to the front outer edge 18, and may be the upper outer edge 15 or the lower outer edge 16.

  Furthermore, in the above embodiment, the notch 20 is formed in a state where the outer edge on the one end side of the paper P is sandwiched by the clamp 30 and the outer edge on the other end side is displaced. It is also possible to use a block-shaped jig that is not used, with the outer edge of the paper P abutted against the inclined surface of the jig, and in this state, the entire paper P is pressed down and the notch 20 is punched. After the notch 20 is formed, the back portion 11 may be formed by returning to the initial state so that the outer edges of the paper P match. In short, according to the present invention, it is only necessary to perform a punching process once, so that it is possible to turn the sheets one by one by fingering from both the front and back sides, and other manufacturing methods are not hindered.
