Explanatory drawing which showed the process, (c) is explanatory drawing which showed the process of cutting out the upper layer of a fold in strip shape. It is explanatory drawing which showed the structure of the folding sheet | seat of the Example.

  Hereinafter, a folding sheet 1 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a folding sheet 1 according to the present embodiment. 2 and 3 are perspective views for explaining a situation where the folding sheet 1 is folded.

  The folding sheet 1 mainly includes a sheet main body 2 on which at least a surface 2a is printed, and division seals 3 attached to the division areas 10A to 10N and 10P of the sheet main body 2. .

  For example, paper can be used for the sheet body 2 formed in the rectangular shape. The sheet body 2 is not limited to paper, and may be a planar material having a small thickness, such as a sheet of synthetic resin, a film, or a thin plate.

  The first surface 21 and the second surface 22 of the sheet main body 2 are printed with a figure, character information, and the like as shown in FIG. Further, as shown in FIG. 1, a valley fold line 11 (shown by a one-dot chain line) as a fold and a mountain fold line 12 (shown by a broken line) as a fold are formed on the sheet body 2.

  The valley fold line 11 can be, for example, an embossed groove. In addition, the mountain fold line 12 can be an embossed ridge. The valley fold line 11 and the mountain fold line 12 are not limited to those applied by embossing. For example, it may be shown that the valley fold line 11 and the mountain fold line 12 can be discriminated (one-dot chain line and broken line, red line and blue line, etc.) by printing.

  And the planar unit area | region enclosed by the outer edge of the fold (11, 12) or the folding sheet | seat 1 becomes division area 10A-10N, 10P. The partition areas 10A to 10N and 10P are the minimum areas that are not folded on the folding sheet 1. That is, when the folding sheet 1 is folded, the partitioned areas 10A-10N and 10P are stacked.

  In the present embodiment, a case will be described in which the valley fold line 11 and the mountain fold line 12 are attached to the sheet body 2 so as to be Miura fold. For this reason, the shape of the partition regions 10A-10N and 10P is a trapezoid or a parallelogram.

  Then, the partition seals 3,... Having a shape slightly smaller than the partition regions 10A-10N, 10P are attached to the partition regions 10A-10N, 10P.

  The edge 31 of the partition seal 3 other than the edge matched with the outer edge of the folding sheet 1 is formed along a line that forms the fold line (11, 12). That is, on both sides of the fold (11, 12), the edge portions 31, 31 of the partition seals 3, 3 on both sides are formed substantially parallel to the fold (11, 12). In other words, an equal width groove 33 (see FIG. 5C) is formed between the partition seals 3 and 3 along the folds (11, 12).

  The partition seal 3 can be rolled as illustrated in the partition region 10A of FIG. The front surface 3a is exposed before the division seal 3 is rolled, but when the division seal 3 is rolled, the back surface 3b and the surface 2a of the sheet main body 2 are exposed. As will be described later, printing can be performed on all of the front surface 3 a and the back surface 3 b of the partition seal 3 and the front surface 2 a of the sheet body 2.

  Further, the partition seal 3 is formed so that it can be repeatedly peeled off and pasted. Specifically, an adhesive layer 23 is formed on the back surface 3b of the partition seal 3 as shown in FIG. The adhesive layer 23 is formed by applying a sealing adhesive to the sheet material 20. For the adhesive, an insoluble paste such as an acrylic adhesive is used.

  On the other hand, a coating layer 24 is formed as a release layer on the surface 2 a (first surface 21) of the sheet body 2 that is the mount side of the partition seal 3. For the coating agent, for example, a silicone resin can be used. Silicone resins include solvent type, solventless type, and emulsion type. For example, UV silicone can be used.

  The folding sheet 1 configured in this way can be folded small by the procedure shown in FIGS. First, FIG. 1 shows a state in which the folding sheet 1 is fully opened. When the folding sheet 1 is contracted from the left and right, the zigzag valley fold lines 11 and 11 and the mountain fold lines 12 and 12 are folded into a state shown in FIG.

  When further compressed than this state, the back surface 2b of the sheet body 2 is hidden, and three layers having a waveform in plan view are overlaid as shown in FIG. Therefore, when the valley fold line 11 and the mountain fold line 12 that are parallel straight lines when folded (see FIG. 1) are folded, the divided regions 10A-10N and 10P are folded and stacked.

  Then, the usage method of the folding sheet | seat 1 comprised in this way is demonstrated, referring FIG. When the folded folding sheet 1 is spread, a small-scale map is printed on the surface 3a of the partition seals 3,.

  If you want to look down on the whole area, you can just look at the map of the surface 3a,. When a detailed map of a certain area (for example, the partitioned area 10H) is desired to be viewed, the section seal 3 attached to the partitioned area 10H is rolled. Then, a large scale map printed on the front surface 2a of the sheet body 2 and the back surface 3b of the partition seal 3 appears, and a detailed map can be confirmed.

  In addition, after viewing the detailed map, the division seal 3 is pasted again so that a small scale map printed on the surface 3a of the division seal 3 can be seen as before.

  Next, the manufacturing method of the folding sheet | seat 1 of this Embodiment is demonstrated. First, as shown in FIG. 5A, the sheet material 20 is pulled out from the roll paper, and printing is performed on both the first surface 21 and the second surface 22 of the sheet material 20 by the double-sided printing machine 4. That is, all the printing necessary to obtain the front surface 3a and back surface 3b of the partition seal 3 and the front surface 2a of the sheet body 2 is performed in this step. In addition, when printing also on the back surface 2b of the sheet | seat main body 2, it is performed at this process.

  After the printing, the sheet material 20 taken up by the rewinder device is set in an off-line processing machine, and the sheet body 20 on the first surface 21 as shown in FIG. The coating layer 24 is formed by applying UV silicone in a range that becomes the surface 2a of 2. Further, after the coating layer 24 is UV-cured, an adhesive is applied to a range that becomes the back surface 3 b of the partition seal 3 to form the adhesive layer 23.

  Then, by folding the sheet material 20 into a valley fold along the center line 25, the adhesive layer 23 and the coating layer 24 are bonded together to form a double structure. That is, the sheet material 20 is folded and the coating layer 24 and the adhesive layer 23 face each other.

  With this folded state, the process proceeds to a step of cutting only the upper sheet material 20 on which the adhesive layer 23 is formed, as shown in FIG. In this step, incisions are made with a die cutter in accordance with the positions of the edge portions 31 of the partition seals 3. Subsequently, when the strip-shaped removal portion 32 sandwiched between the edge portions 31 and 31 is removed, a groove portion 33 appears between the partition seals 3 and 3.

  Therefore, the groove 33 is formed with unevenness that becomes the valley fold line 11 and the mountain fold line 12 by embossing. Further, the folded fold at the position of the center line 25 is cut off and trimmed.

  Up to this point, printing, formation of partition seals 3,..., Embossing, and cutting can be performed in a consistent process. Then, the folds (11, 12) are added to the folding sheet 1 by bending the groove sheet 33 in a predetermined direction.

  Next, the effect | action of the folding sheet | seat 1 of this Embodiment and its manufacturing method is demonstrated.

  The folding sheet 1 of the present embodiment configured as described above is along the valley fold line 11 or the mountain fold line 12 that folds in the partition regions 10A-10N, 10P on both sides of the fold (11, 12). The partition seal 3 formed with the edge 31 is affixed to form a double structure.

  For this reason, a crease | fold (11, 12) can be easily attached between division areas by bending between the division seals 3 and 3. FIG. In other words, the portion where the partition seal 3 is affixed has a double structure and is difficult to bend, and the adjacent sheet main body 2 is easy to bend the groove 33, so it is optional even without using a special jig or device. Can be easily creased. In particular, by embossing the crease (11, 12), it becomes possible to fold more easily.

  Further, if printing is performed on the surfaces 2a and 3a of the sheet main body 2 and the partition seal 3, double information can be packed in the area of one sheet. Furthermore, the amount of information can be further increased by printing on the back surface 3 b of the partition seal 3.

  Moreover, the guide of the crease | fold (11, 12) by the division seal 3 and its edge part 31 can be easily manufactured on the extension line of the process which prints on the sheet | seat material 20 pulled out from the roll paper.

  In addition, the usage method of the folding sheet | seat 1 is not limited to the map mentioned above. For example, an overall design drawing can be printed on the surface 3 a of the partition seal 3, and a detailed design drawing of the corresponding part can be printed so that it appears when the partition seal 3 is put on the surface 2 a of the sheet body 2.

  Further, in automobile advertisements or the like, the appearance of the vehicle may be printed on the surface 3a of the compartment seal 3, and the interior of the vehicle may be printed so that the compartment seal 3 appears on the surface 2a of the seat body 2. it can.

  Furthermore, the folding sheet 1 can be used as a teaching material or a picture book that pops out when the internal organs of the human body appear when the section seal 3 is rolled. The folding sheet 1 can also be used for binding magazines or books.

  Hereinafter, an example of a form different from the above-described embodiment will be described with reference to FIG. The description of the same or equivalent parts as the contents described in the above embodiment will be described with the same terms or the same reference numerals.

  In the above embodiment, the case where the folding sheet 1 is folded by Miura folding has been described, but the present invention is not limited to this. The present invention can be applied to the case of folding in any of two folds, three folds, four folds, Z folds, and the like.

  FIG. 6 shows a development view of the folding sheet 5 when the sheet is folded in the vertical direction and then folded in the horizontal direction. The foldable sheet 5 is divided into six partition regions 50A-50F by a valley fold line 51 or a mountain fold line 52 serving as a linear fold.

  And each of the partition seals 53,... Having a slightly smaller shape is affixed to each of the rectangular (square) partition regions 50A-50F. Even in the case of folding in this simple manner, the folds (51, 52) can be more accurately given by the guides by the edge portions 531 and 531 of the partition seals 53 and 53.

  Other configurations and functions and effects are substantially the same as those in the above-described embodiment, and thus description thereof is omitted.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment or example, and the design changes are within the scope of the present invention. Are included in the present invention.

  For example, in the above-described embodiment, printing is performed on both surfaces (3a, 3b) of the partition seal 3, but the present invention is not limited to this, and printing may be performed only on the surface 3a of the partition seal 3. Moreover, even if it does not print on the whole surface of the sheet | seat material 20, it can also print only in the range which needs printing.

  Furthermore, in the said embodiment and Example, although the structure by which the division | segmentation seal | stickers 3 and 53 were affixed only on one surface of the folding sheets 1 and 5 was demonstrated, it is not limited to this, and it seals on both surfaces of a folding sheet It is also possible to make a triple structure to which is attached. In this case, both sides can be divided seals, but the seal on either side can be of any size or shape as long as it does not overlap the fold.
