  Note that the cutting step in the manufacturing method of the two types of waterproof envelopes may be performed by punching. By doing so, it is possible to manufacture an envelope including a development view having a complicated shape other than a development view formed by simple straight lines.

  The long sheet or sheet suitable for use in the present invention includes, for example, ordinary paper such as various grades of high-quality paper, matte paper, and coated paper, film sheets made of various resins, synthetic paper, nonwoven fabric, and the like. Can be used. Further, there is no particular limitation on the amount of paper or the like, and for the paper, for example, paper in the range of 70 kg to 180 kg can be suitably used.

  Further, the completely adhesive film used in the present invention may be appropriately selected from known heat-sealable print laminates, and the various film sheets may be appropriately selected from transparent or translucent ordinary print laminates. However, in particular, a film sheet for print lamination corresponding to a thermal laminate in which a heat-sensitive adhesive layer is previously formed on one surface of a substrate can be suitably used.

  In addition, the said well-known heat-sealing complete adhesive film sheet can be used suitably for the part provided to the complete adhesion plan surface in long sheet S1 used in the Example mentioned later. The fully adhesive film sheet is a print laminate film sheet having a heat treatment applied to the surface, and the surfaces subjected to the heat treatment after coating are opposed to each other, and when the heat / pressure treatment is applied, the film completely adheres without being peeled off. be able to.

  For example, a folding sewing machine, a folding line, or the like is preferably used as the folding means formed on the fold line (not necessarily described) of the long sheet and the sheet. Although there is no particular restriction on the ratio of cutting and uncutting of the folding sewing machine, it is convenient that the cutting ratio is large and relatively easy to fold because the film is covered and reinforced in a later step. The shape of the folding sewing machine is not limited, and may be a combination of a plurality of fine holes, a plurality of curved cuts, a plurality of bent straight lines or curves, in addition to a normal straight broken line. There are no particular restrictions on the width or depth of the crease. In short, any folding means that can be easily folded even when the film is coated may be used. Furthermore, other known folding means may be employed.

  In the cutting process of the present invention, it is possible to suitably use a cutting means using a cross cutting blade composed of a combination of a die cut roll and a backup roll. Further, a cutting means using punching blades of various shapes with a die cut roll as a magnet specification (for example, flexible pinnacle die: manufactured by Tsukaya Cutlery Co., Ltd.) is also possible. In that case, it becomes possible to change the shape of the envelope, and the aesthetic feeling is improved.

  According to the method for manufacturing a waterproof envelope of the present invention, the type and amount of paper can be freely selected even if the number of copies is small. Moreover, since the inner side surface or the outer side surface of the envelope to be manufactured is laminated with a film, the waterproof effect is very high and it is also resistant to breakage. And such an envelope can be manufactured very efficiently by a continuous flow operation.

In this way, a waterproof envelope in which the upper and lower openings are sealed is completed.

[Example 1: Manufacturing method of waterproof envelope when long sheet S1 is used]
Next, the manufacturing method of the waterproof envelope according to the present invention will be described in an easy-to-understand manner.
As shown in FIGS. 8A and 8B, the long sheet S1 used in the method for manufacturing a waterproof envelope according to the present invention has a first leaf piece 1, a second leaf piece 2 and a third leaf piece 3 formed in a fold line. The unit sheet t1 is formed by being connected in the lateral direction via the folded folding machine 4 (which may be a folding line or the like) 4 and the folding sewing machine 5 (which may be a folding line or the like). Are connected to each other in the vertical direction via the planned cut line 7. And the marginal part 10 in which the marginal hole 9 was provided is connected with the outer side of the 1st leaf piece 1 and the 3rd leaf piece 3 via the scheduled cut line 8, respectively. Further, a folding sewing machine 6 or the like may be formed on the upper and lower cut lines 7 of the unit sheet t1.

  As shown in FIG. 8 (A), on the surface of the second leaf piece 2, various information such as a postage stamp column, a postal code column, or an advertisement (not shown) may be described. Similarly, although not shown on the surface of the third leaf piece 3, various information may be described. Note that the surface of the first leaf piece 1 is covered with a completely adhesive film sheet K as will be described later, and is finally hidden, so that information is displayed except in special cases. Further, since the back side of the long sheet S shown in FIG. 5B becomes the inner surface side after the waterproof envelope X is completed, no information is described except in special cases.

  The long sheet S1 configured as described above is folded into a bellows from, for example, a planned cut line 7 (folding lines, folding sewing machines and the like may be formed), and is illustrated in a block state as shown in FIG. It is placed in the uppermost stream of the lower left middle system. Then, when pulled up to the upper support roller 11, the marginal hole 9 is engaged with the pin of the pin tractor 12 arranged on the right side while changing the direction almost horizontally, and a pair of heat rollers 13a arranged on the right side. , 13b.

  When the folding sewing machines 4 and 5 are not formed in advance, they are arranged in parallel on the common backup roller 101c between the support roller 11 and the pin tractor 12, for example, as shown in FIG. You may make it send to the laminating apparatus arrange | positioned on the right side, forming the said folding sewing machines 4 and 5 with the sewing machine blade 101a, the creasing blade 101b, etc. FIG.

  In the laminating apparatus, a fully adhesive film sheet K fed out from a roll waiting upward, and a fully adhesive film sheet K and film sheet F waiting in a parallel state below are respectively fed out and heated by heat rollers 13a and 13b as shown in FIG. And as shown by the oblique line in (B), it aligns with each coating planned surface of the front and back of the long sheet S1.

  A heat-sensitive adhesive layer (not shown) is formed on the surface of the complete adhesive film sheet K and the film sheet F that contacts the long sheet S1. When both are aligned and pass between the heat rollers 13a and 13b, a heating / pressurizing process is performed, whereby the various film sheets and the long sheet S1 cannot be separated by the heat-sensitive adhesive layer exhibiting adhesiveness. It is glued.

  The long sheet S1 in which various film sheets are coated at required locations on the front and back sides is then used to cut the marginal portion 10 outside the first leaf piece 1 by a cutting device comprising a slit blade 14a and a backup roller 14b arranged on the right side. After the cutting, the sheet is further fed to the right folding device by a pair of nip rollers 15a and 15b. The excision apparatus may be replaced with a known slitter.

  In the folding device, the first leaf piece 1 of the long sheet S1 from which the marginal portion 10 has been removed is a folding sewing machine 4 (a folding line may be used as shown in FIGS. 11A, 11B, and 13A). ) Is folded so that the back surfaces of the first leaf piece 1 and the second leaf piece 2 face each other. Next, as shown in FIGS. 12A, 12B, and 13B, the back surfaces of the second leaf piece 2 and the third leaf piece 3 are opposed to each other from the folding sewing machine 5 (which may be a folding line). It is folded in half.

  When the long sheet S1 pulled up to the support roller 17 while being folded as described above changes its direction substantially horizontally, the pin of the pin tractor 18 arranged on the right side and the marginal portion 10 of the marginal portion 10 outside the third leaf piece 3 are arranged. The hole 9 is engaged and fed into a cutting device comprising a slit blade 19a and a backup roller 19b arranged on the right side. Then, as shown in FIG. 14, after the remaining marginal portion is cut, the pair of nip rollers 20a and 20b are sent to a cutting device including a die cut roller 21a and a backup roller 21b arranged on the right side.

  In the cutting apparatus, the unit sheet t1 is cut continuously from the planned cut line 7 shown in FIG. 14, and finished into a single waterproof envelope X as shown in FIG. The cross-sectional view taken along the line VII-VII shown in the figure at this time is the same as FIGS. 2A and 3, although the completely adhesive film sheets K facing each other are not bonded.

  The unit sheet t1 is then sent out to the envelope forming apparatus arranged on the right side. In the envelope forming apparatus, a pair of conveying rollers 22a and 22b and a pair of heater panels 23a and 23b are alternately arranged, and the unit sheet t1 passing between the heater panels is heated and a pair of additional rollers disposed at the outlet. Pressure is applied by the pressure rollers 24a and 24b. Then, the completely adhesive film sheets K whose surfaces are subjected to the heat treatment by the heating / pressurizing treatment are adhered to each other, and the first leaf piece 1 and the third leaf piece 3 are completely adhered so as not to be peeled. The waterproof envelope X manufactured as described above is finally discharged to the stacker 25 composed of a belt conveyor or the like and sequentially stacked.

[Example 2: Manufacturing method of waterproof envelope when single sheet is used]
As shown in FIG. 16, the sheet S <b> 2 used in the method for manufacturing a waterproof envelope of the present embodiment has two waterproof sheets in a state surrounded by a margin portion 37 in the transport direction and a margin portion 38 perpendicular to the transport direction. An envelope unit sheet t2 is printed. In the unit sheet t2, a first leaf piece 31, a second leaf piece 32, and a third leaf piece 33 are connected in a lateral direction via a folding machine 34 (which may be a folding line) and a folding machine 35 (which may be a folding line). The folding sewing machine 36 is formed in the lateral direction along the upper and lower sides. In addition, in a blank portion 38 perpendicular to the conveyance direction on the upper side of each waterproof envelope unit sheet t2, a band-like mark M is described for use in sensor reading in a manufacturing process described later.

  On the surface of the second leaf 32, various information such as a postage stamp field, a postal code field, or an advertisement or a recipient's address name (not shown) may be described. Similarly, although not shown on the surface of the third leaf piece 33, various information may be described. Note that the surface of the first leaf piece 31 is covered with a completely adhesive film sheet K as will be described later, and is finally hidden, so that information is displayed except for special cases. Further, since the back surface side of the sheet S2 shown in FIG. 17 becomes the inner surface side after the waterproof envelope X is completed, information is not described except for a special case.

  The sheet S2 configured as described above is stacked on the most upstream sheet platform of the system as shown in FIG. 18, for example. Then, from the uppermost sheet S2, for example, by a sheet feeding device made up of, for example, a suction pad 41 or the like, the end portions of the sheet S2 that are sequentially spaced or abutted or overlap each other are overlapped onto the right conveyance table. It is paid out. And it is pulled by the laminating apparatus which consists of a pair of heat roller 43a, 43b arrange | positioned by the pair of nip rollers 42a, 42b on the right side.

  When the folding sewing machines 34 and 35 are not formed in advance, for example, as shown in FIG. 30B, they are arranged in parallel on a common backup roller 102c between the pair of nip rollers 42a and 42b and the laminating apparatus. The folding sewing machines 34 and 35 may be formed by the sewing machine blade 102a and the creasing blade 102b, and the like, and sent to a laminating apparatus disposed on the right side.

  In the laminating apparatus, a completely adhesive film sheet K fed out from a roll waiting upward, and a fully adhesive film sheet K and film sheet F standing in a parallel state below are respectively fed out and heated by heat rollers 43a and 43b, as shown in FIGS. As shown in FIG. 4, the sheet is aligned with the respective coating planned surfaces on the front and back surfaces of the sheet S2. The heat rollers 43a and 43b are heated and pressurized, and are adhered and covered with a heat-sensitive adhesive layer provided on the various film sheets so as not to be peeled off. At that time, each sheet S2 fed back and forth is in a continuous state by the various film sheets.

  The sheet S2 in which various film sheets are coated at required locations on the front and back surfaces is then transported in a conveying direction as shown in FIG. 21 by a cutting device comprising a slit blade 44a and a backup roller 44b arranged in parallel on the right side. After the outer margin portions 37, 37 along the outer side are cut off, they are further fed to the right folding device by a pair of nip rollers 45a, 45b. The excision apparatus may be replaced with a known slitter.

  In the folding device, the first leaf piece 31 of the sheet S2 from which the blank portions 37, 37 have been cut out, from the folding sewing machine 34 (which may be a crease) as shown in FIG. One sleeve is folded so that the back surfaces of the leaf pieces 32 face each other. Next, as shown in FIG. 23, the folding machine 35 (which may be a folding line) is folded in half so that the back surfaces of the second leaf piece 32 and the third leaf piece 33 face each other.

  When the sheet S2 folded as described above is turned almost horizontally by the support roller 47, the pair of nip rollers 48a and 48b disposed on the right side and the cutting blade 50a disposed on the right side and the fixed sheet S2 are fixed. It is sent out to a cutting device comprising the blade 50b.

  In the cutting apparatus, when the sensor 49 arranged on the upstream side reads the mark M1 displayed on the sheet S2 passing in the direction of the arrow in FIG. 23 from above, up to a predetermined side L1. And the side L1 is cut. The electrical counting is continued, and the side L2 is cut at the moment when the side L2 passes through the cutting device, and the first unit sheet t2 is cut out.

  The cutting operation by the reading of the sensor 49 is also performed for the passing mark M2, and the cutting at the side L3 and the side L4 is performed in the same manner as described above to cut out the second unit sheet t2. In this way, the above operation is repeated for the succeeding sheet S2, and the margin 38 perpendicular to the conveying direction shown in FIG. 23 and the margins of the preceding and following sheets S2 are exposed. The blank portion 39, which is the total of the film sheet portions, is eliminated, and the unit sheet t2 is continuously cut out and finished into a single waterproof envelope X shown in FIG.

  Thereafter, the unit sheet t2 is then sent out to the envelope forming apparatus arranged on the right side. In the envelope forming apparatus, a pair of conveying rollers 51a and 51b and a pair of heater panels 52a and 52b are alternately arranged, and the unit sheet t2 passing between the heater panels is heated and a pair of additional rollers arranged at the outlet. Pressure is applied by the pressure rollers 53a and 53b. The completely adhesive film sheets K whose surfaces are heat-treated by the heating / pressurizing treatment are bonded to each other, and the first leaf piece 31 and the third leaf piece 33 are completely bonded together so as not to be peeled off. The waterproof envelope X manufactured as described above is finally discharged to the stacker 54 formed of a belt conveyor or the like and sequentially stacked.

[Other Examples]
The present invention is not limited to the above embodiments.
For example, as shown in FIG. 24, for example, a window-like hole P may be provided in the lower folded portion of the unit sheet t3. By comprising in this way, as shown in FIG. 25 (A), the adhesive layer of the various film sheets coat | covered on each leaf piece back surface will expose | express from the said window-shaped hole P. FIG. Then, as shown in FIG. 26, when the lower folded portion is folded and then heated and pressurized again, the inner side of the folded portion is adhered to the leaf pieces on the waterproof envelope body side to adhere various film sheets exposed from the window-shaped holes P. It is fixed and sealed more firmly by the agent layer.

  Moreover, in the above-mentioned Example, it becomes the structure by which the envelope inner surface side after completion is coat | covered with various film sheets. However, not only the envelope inner surface side coating but also the outer surface side coating or the inner and outer surface coatings may be supplemented to cover the entire envelope as a result. In that case, for example, as shown in FIG. 27, a window-shaped hole P may be provided in the entire lower folded portion of the unit sheet t4 so that the positions thereof are aligned after the waterproof envelope is completed. In this case, as shown in FIG. 28 (A), for example, a mat-like film sheet MF is coated on the surface of the second leaf piece 72 serving as the address surface, and the back surface of the second leaf piece 72 is covered as shown in FIG. 28 (B). 29, the folded portion can be sealed using the heat-sensitive adhesive layers of various film sheets that are exposed in the window-like hole P as shown in FIG.

  Furthermore, there are no particular restrictions on the number (number of rows) or the shape of the window-like holes P formed in the folded portion.
