[First embodiment]
Hereinafter, a method for manufacturing a pop-up paper product according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a flowchart showing steps of a first embodiment of a method for manufacturing a pop-up paper product according to the present invention, and FIG. 2 is an explanatory diagram showing shapes formed by the steps in the first embodiment. In the illustrated pop-up paper product, the pop-up part has a mountain shape, for example, a shape imitating Mt. Fuji.

  First, a sheet of paper 1 having a substantially rectangular shape is prepared. The paper 1 can be used in a substantially rectangular shape, but here, in order to make the pop-up portion 5 have the shape of Mt. It has been pulled out. Then, snow is drawn on the mountain top by printing, and a predetermined coloring is applied to the mountain skirt. Then, as shown in FIG. 2 (a), the sheet 1 is folded in half by valley-folding the approximate center of the sheet 1 in the longitudinal direction (step S1).

Next, a predetermined position (the point P in FIG. 2B) on the free end 21 of the upper half surface 2 that has been positioned at the uppermost surface by the two-folding process in step S1, and valley folding in the two-folding process in step S1. The intersection of the center line 33 and the free end 21 with a predetermined location (point Q in FIG. 2B) on the center line 33 formed in the direction orthogonal to the fold line 31 through the center portion 31a of the folded line 31. Gluing is performed on a predetermined portion of the triangle formed by connecting 31b ( step S2). In the case of this embodiment, the predetermined location on the free end 21 of the upper half surface 2 is a point P in FIG. 2B (a location located beside the top portion of Mt. Fuji drawn on the upper half surface 2). The predetermined position on the center line 33 formed in the direction orthogonal to the fold line 31 through the center part 31a of the fold line 31 folded in the two-fold process of step S1 is a point Q in FIG. In the present embodiment, the shape of the left and right surfaces divided by the line 35 is symmetric, so the point P can be set at two locations on the left and right as shown in FIG. It does not matter. The predetermined portion (glue portion 25) to be glued preferably includes at least the free end 21 portion from the point P to the intersection point 31b, but the triangle 23 formed by the point P, the point Q and the intersection point 31b. The entire surface may be used.

  Next, as shown in FIG. 2C, the paper 1 is folded into four by folding the valley along the center line 33 (step S3). Thereby, the part contact | abutted to the gluing part 25 is glued, and the pop-up part 5 is formed. Then, when the folded paper 1 is opened along the center line 33, as shown in FIG. 2D, the pop-up portion 5 rises and Mt. Fuji stands up (step S4). It should be noted that the folds, streaks, or cuts are made in advance in the lines 7 and 7 that are the bottom of Mt. Fuji, so that the pop-up portion 5 can be raised smoothly when the quadruple folded paper 1 is opened.

  In the first embodiment described above, the shape of the pop-up portion 5 is the shape of Mt. Fuji. However, other shapes such as a heart shape, a butterfly, a flower, and a building can be used.

[Second Embodiment]
Next, a second embodiment will be described. In the second embodiment, the pop-up portion 5 has a shape that opens and rises in a substantially rhombus shape. First, a sheet of paper 1 having a substantially rectangular shape is prepared. Then, as shown in FIG. 4A, the paper 1 is folded in half by folding the substantially center in the longitudinal direction of the paper 1 with a fold line 41 in the same way as in the first embodiment (step). S11).

  Next, the upper half surface 2 is further folded in a fold line 42 parallel to the fold line 41 formed in the bi-folding process in step S11. As shown in FIG. 4 (b), it is folded and folded (step S12). And as shown in FIG.4 (c), in the folding process of step S12, the point P which is the predetermined location on the free end 21 of the upper half surface 2 which was located in the uppermost surface by the folding process of step S12, and step S12. A center portion 42a of the folded fold line 42 and an intersection point 42b where a line 43 extending in a direction perpendicular to the fold line 42 from the center portion 42a of the folded fold line 42 in the folding step of step S12 intersects the free end 21. A predetermined portion of the formed triangle 23 is glued to form a glued portion 25 (step S13). Here, in the present embodiment, the corners of the free end 21 of the upper half surface 2 are set as the points P as the predetermined locations on the free end 21 of the upper half surface 2, but the present invention is not limited to this. In addition, since the gluing is folded in a center line 44, which will be described later, in the next step (four-folding step), the corner P on either side, not the corner on either side, the center 42a, The glue portion 25 may be formed only on the triangle 23 on one side formed by connecting the intersection 42b.

  It is of course possible to replace the procedure of the folding process of step S11 and the folding process of step S12, first perform the folding process of step S12, and then perform the folding process of step S11.

  Next, as shown in FIGS. 4D and 4E, a center line 44 is formed in a direction perpendicular to the fold line 41 through the center portion 41a of the fold line 41 that has been valley-folded in the bi-folding step of step S11. Further, the paper 1 is folded into four by further folding the valley (step S14). As a result, the glue portion 25 is glued to form the pop-up portion 5. Then, when the folded paper 1 is opened along the center line 44, as shown in FIG. 4 (f), the substantially rhombic pop-up portion 5 is opened and stands up (step S15). As in the first embodiment, the point P and the central portion 42a that form the pop-up portion 5 are formed on the lines 7 and 7 in advance by making streaks or cuts in the creases so that the folded paper 1 is opened. The pop-up part 5 can be raised smoothly.

  Also in the second embodiment described above, the shape of the pop-up portion 5 can be, for example, a heart shape, Mt. Fuji, or other appropriate shape. FIGS. 5A to 5F are explanatory diagrams showing the shape of each process when the pop-up part 5 is a heart shape, and FIGS. 6A to 6F are each process when the pop-up part is a Mt. Fuji type. It is explanatory drawing which shows the shape. Since each process is the same as Step S11 to Step S15 described above, detailed description is omitted. In particular, in the Mt. Fuji type shown in FIG. 6, the line connecting the intersection 46a where the fold line 41 intersects the side edge and the central part 42a is the fold line 46, so that the mountain hem is formed long.

  Here, an example of mechanical folding when the second embodiment is performed by a paper folding machine with respect to the above-described two-folding process (steps S1 and S11), the folding process (step S12), and the four-folding process (steps S3 and S14). I will explain. 7 and 8 are schematic views showing the movement of the paper folding machine. In the following, a case will be described in which the folding process in step S12 is performed first, and then the step S11 is folded twice. As shown in FIG. 7A, the illustrated paper folding machine 50 has six rollers 51a to 51f, baffle plates 53a and 53d, and a gap into which the paper 1 is inserted. Guide members 55a and 55b provided with contact portions 53b and 53c are provided. Specifically, the roller 51a and the roller 51b are arranged to face each other, and the paper 1 that has been transferred on the guide stage 57a by the rollers 51a and 51b is sent forward (step S21).

  A baffle plate 53a is disposed in front of the rollers 51a and 51b in the exit direction, and the paper 1 is changed in the traveling direction so as to be guided between the rollers 51b and 51c. Then, as shown in FIG. 7B, the paper 1 whose traveling direction has been changed by the baffle plate 53a enters the gap between the guide members 55a by the rollers 51b and 51c (step S22). An abutting portion 53b is provided in the middle of the gap of the guide member 55a, and the paper 1 abuts against the abutting portion 53b to prevent further entry. On the other hand, since the paper 1 is further pushed by the rollers 51a and 51b, as shown in FIG. 7C, distortion occurs near the entrance of the guide member 55a (step S23), as shown in FIG. 7D. Then, the distorted portion is drawn by the roller 51c and the roller 51d arranged to face each other and folded back into two (step S24). The folding line at this time is the folding line 42.

  Further, as shown in FIG. 7E, the paper 1 folded back by the folding line 42 enters the gap between the guide members 55b by the rollers 51c and 51d, and comes into contact with the contact portion 53c of the guide member 55b. The above intrusion is prevented (step S25). Then, as shown in FIG. 7 (f), the paper 1 is distorted near the entrance of the guide member 55b (step S26), and as shown in FIG. 8 (a), the rollers in which the distorted portions are arranged to face each other. 51e and the roller 51f are pulled in, and as shown in FIG.8 (b), the upper half surface 2 is further folded in two (step S27). The folding line at this time is the folding line 41. Then, as shown in FIG. 8C, the paper 1 is discharged onto the guide stage 57b by the rollers 51c and 51d (step S28). Thereafter, a predetermined portion of the triangle 23 is glued by a bonding device (not shown), the paper 1 is rotated by 90 °, and the paper is folded further by the center line 44 by the paper folding machine configured as described above. The pop-up paper product of the embodiment is completed.

  As described above, the preferred embodiments of the present invention have been described in detail, but the present invention is not limited to the specific embodiments described in detail, and is within the scope of the gist of the present invention described in the claims. Needless to say, various modifications and changes are possible.
