  The cutting process of the six types of manufacturing methods 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 uses, for example, ordinary paper such as high-quality paper, matte paper, and coated paper, as well as film sheets made of various resins, synthetic paper, nonwoven fabric, and the like. Can do. Also, there is no particular limitation on the amount of paper, and paper in the range of 70 kg to 180 kg can be used preferably in terms of four-and-one companion.

  The fully adhesive film sheet used in the present invention may be appropriately selected from those for known heat-sealable print laminates, and the film sheet may be appropriately selected from those for known print laminates. However, in particular, a film sheet for print lamination corresponding to a thermal laminate in which a heat-sensitive adhesive layer is formed on one surface of a substrate can be suitably used.

  The complete adhesive film sheet to be coated on the surface to be completely bonded is heat-treated on the surface, and when the heat-treated surfaces are opposed to each other and subjected to heating / pressurizing treatment, they cannot be peeled off. It will be completely bonded.

  For example, a folding machine or a folding line is preferably used as the folding means for the long sheet and the sheet. Although there is no particular restriction on the ratio of cutting and uncutting of the folding sewing machine, since the film is coated and reinforced in a later step, it is convenient that the folding machine is relatively easy to fold with a large cutting ratio and a small uncut ratio. 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, etc. in addition to a normal broken line consisting of a plurality of short straight cuts. Absent. In short, any folding means can be used as long as it can be easily folded even if the film is coated on the surface of the sheet. The width and depth of the crease are not particularly limited and are selected from those that can be bent easily.

  There is no restriction on the time when the folding means is formed on various sheets. For example, it may be already formed at the stage of placing various sheets in the feeding process, or may be formed between the feeding process and the coating process, and further formed with the film sheet after the coating process. Depending on the case, the formation in each of the above stages may be executed in a composite manner.

  In the cutting process of the present invention, it is possible to suitably use a cutting means using a transverse cutting blade made up of a combination of a die cut roll and a backup roll, or a guillotine type cutting means made up of a cutting blade and a fixed blade. In addition, a cutting means using punching blades of various shapes in place of the die cut rolls with magnet specifications can be used. In that case, it becomes possible to change the shape of the envelope, and the aesthetic feeling in the appearance of the envelope is improved.

  According to the method for manufacturing an envelope with a window of the present invention, the type and amount of paper can be freely selected even if the number of copies is small when manufacturing the envelope. Moreover, since the inner and outer surfaces of the envelope to be manufactured are laminated with a film, the waterproof effect is very high, and the envelope is also resistant to breakage. In addition, the window part is covered with a film sheet, and the address face of the contents inserted and fixed by the static electricity does not come into close contact with the window part, so even if the contents are smaller than the envelope, It is extremely convenient without any trouble in reading work.

Hereinafter, the present invention will be described with reference to the drawings.
First, an envelope with a window will be described.
As shown in FIG. 1 and FIG. 2, which is a cross-sectional view of three types of the drawings, the envelope X with a window of the present invention is, for example, as shown in FIG. A single leaf piece 1, a second leaf piece 2, and a third leaf piece 3 are bonded to the surface of the first leaf piece 1 along the end of the back surface of the third leaf piece 3. For example, a postage stamp column, a postal code column, and other various information are described.

  As shown in FIGS. 3 and 4 which are enlarged views of FIGS. 2 (A) and 2 (C), the front and back surfaces of the second leaf piece 2 and the outer surface of the third leaf piece 3 are coated with a film sheet F, The window 7 is covered with the film sheets F and F so that the internal information can be seen through. And the opposing surface of the 1st leaf piece 1 and the 3rd leaf piece 3 is adhere | attached by the completely adhesive film sheet K so that peeling is impossible. Thus, an unbonded space in which various inclusions such as DM can be enclosed is formed between the first leaf piece 1 and the second leaf piece 2 and the second leaf piece 2 and the third leaf piece 3 which are folded and overlapped. Yes. As shown in FIG. 3, the folding sewing machine 6 provided on the left and right sides penetrates only the first leaf piece 1, the second leaf piece 2 and the third leaf piece 3, and the film sheet F covering each leaf piece and the complete It is not applied to the adhesive film sheet K.

Next, the usage method of the envelope with a window is demonstrated below.

Then, the left and right end portions are folded in the arrow direction shown in FIG. 2B from the folding sewing machine 6 provided at the left and right end portions. Further, as shown in FIGS. 5 (B), 6 (A), 6 (B) and 7, the left and right folded ends are attached to the third leaf piece 3 by a known stopper such as an adhesive tape T, for example. Adhere. In this way, an envelope with a window in which the left and right openings are sealed is completed.

[Example 1: Manufacturing method of envelope with window when long sheet S1 is used]
Next, the manufacturing method of the envelope X with a window according to the present invention will be described in an easily understandable manner.
As shown in FIGS. 8 and 9, the long sheet S <b> 1 used in the method for manufacturing an envelope with a window according to the present invention has a first leaf piece 1, a second leaf piece 2, and a third leaf piece 3 folded through sewing machines 4 and 5. The unit sheets t1 are connected in the horizontal direction, and the unit sheets t1 are connected in the vertical direction via the upper and lower cut lines 8. And the marginal part 11 in which the marginal hole 10 was provided is connected with the outer side of the 1st leaf piece 1 and the 3rd leaf piece 3 via the cutting planned line 9, respectively. Further, a folding sewing machine 6 is formed along the upper and lower cut lines 7 of the unit sheet t1.

  As shown in FIG. 8 and FIG. 9, the second leaf piece 2 may be punched with a window portion 7 and may be filled with various information such as a postal code column or an advertisement although not shown. 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. Moreover, since the back side of the long sheet S1 shown in FIG. 9 becomes the inner surface side after completion of the envelope with window ×, no information is described except in a special case.

  The long sheet S1 configured as described above is folded into a bellows from, for example, a cut-out planned line 8 (not necessarily displayed and a folding sewing machine or the like may be formed), as shown in FIG. In the block state, it is arranged in the uppermost stream of the system at the lower left in the figure. Then, when pulled up to the upper support roller 21, the marginal hole 10 is fitted to the pin of the pin tractor 22 arranged on the right side while changing the direction almost horizontally, and a pair of heat rollers 23a arranged on the right side. , 23b.

  In the laminating apparatus, the fully adhesive film sheet K and the film sheet F are fed out from the roll waiting in the upper side in the parallel state, and the fully adhesive film sheet K and film sheet F are respectively fed out from the roll waiting in the lower side in the parallel state. 23b is aligned with the respective planned coating surfaces on the front and back surfaces of the long sheet S1, as indicated by hatching in FIG. 11 and FIG.

  A heat-sensitive adhesive layer is formed on the contact side surface of the complete adhesive film sheet K and the film sheet F with the long sheet S1, although not shown. When the two are aligned and pass between the heat rollers 23a and 23b, a heat and pressure treatment is performed, whereby the various film sheets and the long sheet S1 are bonded to each other by the heat-sensitive adhesive layer exhibiting adhesiveness. It is done.

  As shown in FIG. 13, the long sheet S <b> 1 having various film sheets coated on the required front and back sides is then cut by a cutting device including a slit blade 24 a and a backup roller 24 b arranged on the right side. 1 After the outer marginal portion 11 is cut off, it is further fed to the right folding device by a pair of nip rollers 25a and 25b. The excision apparatus may be replaced with a known slitter.

  By the way, the cutting device between the laminating device and the nip rollers 25a and 25b can be used to form the folding means. For example, by sharing the backup roller 24b that constitutes the excision apparatus and arranging the sewing machine blade and the scoring blade in parallel with the slit blade 24a, the folding means can be formed on the folding means forming planned line simultaneously with the excision. Of course, a backup roller may be newly provided between the laminating apparatus and the nip rollers 25a and 25b, and the folding means forming means may be arranged.

  In the folding device, the first leaf piece 1 of the long sheet S1 from which the marginal portion 11 has been cut is formed from the folding sewing machine 4 to the first leaf piece 1 and the second leaf piece as shown in FIGS. 14, 17A and 17B. One sleeve is folded so that the two back surfaces face each other. Next, as shown in FIGS. 15, 17 </ b> B, and 17 </ b> C, the folding machine 5 is folded in half so that the front surface of the first leaf piece 1 and the back surface of the third leaf piece 3 face each other. In FIGS. 17A, 17B and 17C, various film sheets coated on the front and back surfaces of each leaf piece are omitted in order to avoid complication of the drawing.

  As described above, the long sheet S1 pulled up to the support roller 27 while being folded is changed to a substantially horizontal direction, and the pin of the pin tractor 28 arranged on the right side and the marginal portion 11 on the outer side of the third leaf piece 3 are aligned. The hole 10 is fitted and fed into a cutting device comprising a slit blade 29a and a backup roller 29b arranged on the right side. Then, as shown in FIG. 16, after the remaining marginal portion 11 is cut, the pair of nip rollers 30a and 30b are sent to a cutting device including a die cut roller 31a and a backup roller 31b arranged on the right side.

  In the cutting apparatus, the unit sheet t1 is cut continuously from the planned cut line 8 shown in FIG. 16, and finished into a single envelope X with a window as shown in FIGS. At this time, the completely adhesive film sheets K facing each other shown in FIGS. 3 and 4 are not adhered to each other, but the completely adhesive film sheets K are completely adhered to each other by an envelope forming apparatus described later. .

  The unit sheet t1 is then sent out to the envelope forming apparatus arranged on the right side. As shown in FIG. 10, the envelope forming apparatus has a pair of conveying rollers 32a and 32b and a pair of heater panels 33a and 33b arranged alternately. The unit sheet t1 passing between the heater panels is heated and exited. Is pressed by a pair of pressure rollers 34a and 34b. 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 windowed envelope X manufactured as described above is finally discharged onto the stacker 35 formed of a belt conveyor or the like and sequentially stacked.

[Example 2: Manufacturing method of envelope with window when a sheet is used]
As shown in FIG. 18, the sheet S2 used in the second envelope manufacturing method of the present embodiment is surrounded by, for example, a margin portion 47 in the transport direction and a margin portion 48 perpendicular to the transport direction. The two unit sheets t2 for envelopes with a window are printed. In the unit sheet t2, a first leaf piece 41, a second leaf piece 42, and a third leaf piece 43 are connected laterally via folding machines 44 and 45, and a folding sewing machine 46 is formed along the upper and lower sides. A band-like mark M for use in reading a sensor in a manufacturing process described later is described in a blank portion 48 perpendicular to the conveying direction on the upper side of each envelope unit sheet t2 with window.

  A window 49 is punched on the surface of the second leaf piece 42, and 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 43, various information may be described. Note that the surface of the first leaf piece 41 is covered with a completely adhesive film sheet K as will be described later, and is eventually hidden, so that information is displayed except in special cases. Further, since the back surface side of the sheet S2 shown in FIG. 19 becomes the inner surface side after completion of the envelope X with a window, information is not described except for a special case.

  For example, as shown in FIG. 20, the sheet S2 configured as described above is stacked on the uppermost sheet mount of the system. Then, from the uppermost sheet S2, for example, by a sheet feeding device composed of the suction pad 51 or the like, the ends of the sheet S2 which are sequentially spaced or abutted or overlap each other are overlapped onto the right conveyance table. It is paid out. And it is pulled to the laminating apparatus which consists of a pair of heat roller 53a, 53b arrange | positioned by the pair of nip rollers 52a, 52b on the right side.

  In the laminating apparatus, the fully-adhesive film sheet K and the film sheet F fed out from the roll waiting in the upper side in the upward state, and the complete adhesive film sheet K and the film sheet F waiting in the lower side in the parallel state are fed out from the roll, respectively. As shown in FIGS. 21 and 22 at 53a and 53b, they are aligned with the respective coating planned surfaces on the front and back surfaces of the sheet S2. The heat rollers 53a and 53b are heated and pressurized, and are adhered and coated so as not to be peeled off. At that time, the single sheet S2 fed back and forth is in a continuous state with various film sheets coated on the front and back surfaces.

  The sheet S2 in which various film sheets are coated at required portions on the front and back surfaces is then transported in a conveying direction as shown in FIG. 23 by a cutting device comprising a slit blade 54a and a backup roller 54b arranged in parallel on the right side. After the outer margin portions 47 and 47 along the line are cut off, they are further fed to the right folding device by a pair of nip rollers 55a and 55b. The excision apparatus may be replaced with a known slitter.

  As in the case of the long sheet, the folding means can be formed by diverting the cutting device between the laminating device and the nip rollers 55a and 55b. For example, by sharing the backup roller 54b that constitutes the excision apparatus and arranging the sewing blade and the scoring blade in parallel with the slit blade 54a, the folding means can be formed on the planned folding means forming line simultaneously with the excision. Of course, a backup roller may be newly added between the laminating apparatus and the nip rollers 25a and 25b to arrange the folding means forming means.

  In the folding device, the first leaf piece 41 of the single-wafer sheet S2 from which the blank portions 47, 47 have been cut out is arranged so that the back surfaces of the first leaf piece 41 and the second leaf piece 42 face each other from the folding sewing machine 44 as shown in FIG. Folded on one sleeve. Next, as shown in FIG. 25, the folding machine 45 is folded in half so that the back surfaces of the second leaf piece 42 and the third leaf piece 43 face each other.

  When the sheet S2 folded as described above is turned almost horizontally by the support roller 57, the pair of nip rollers 58a and 58b disposed on the right side and the cutting blade 60a disposed on the right side and the fixed sheet S2 are fixed. It is sent out to a cutting device comprising the blade 60b.

  In the cutting apparatus, when the sensor 59 arranged on the upstream side reads the mark M1 displayed on the sheet S2 passing in the direction of the arrow in FIG. 25 from above, up to a predetermined side L1. And the side L1 is cut. Subsequently, the electric counting is continued, and then the first unit sheet t2 is cut out by cutting at the moment when the side L2 passes through the cutting device.

  The cutting operation by the reading of the sensor 59 is also performed on the mark M2 that passes subsequently, and the cutting at the side L3 and the side L4 is performed in the same manner as described above, and the second unit sheet t2 is cut out. In this way, the above operation is repeated in the subsequent sheet S2, the margin 48 perpendicular to the conveying direction shown in FIG. 25 is eliminated, and the unit sheet t2 is continuously cut out as shown in FIG. A single envelope X with a window is finished.

  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 transport rollers 61a and 61b and a pair of heater panels 62a and 62b are alternately arranged. The unit sheet t2 passing between the heater panels is heated and a pair of processing rollers disposed at the outlet. Pressure is applied by the pressure rollers 63a and 63b. The completely adhesive film sheets K whose surfaces are heat-treated by the heating / pressurizing process are bonded to each other, and the first leaf piece 41 and the third leaf piece 43 are completely bonded together so as not to be peeled off. The windowed envelope X manufactured as described above is finally discharged to the stacker 64 composed of a belt conveyor or the like and sequentially stacked.

[Other Examples]
The envelope with a window of the present invention is not limited to the above embodiment, and for example, a window-like hole P may be provided in the lower folded portion of the unit sheet t3 as shown in FIGS. With this configuration, the adhesive layers of various film sheets coated on the back of each leaf piece are exposed from the window-shaped hole P as shown in FIGS. Then, in the finish shown in FIG. 30, as shown in FIG. 31, the various films exposed from the hole P in the lower folded portion are bonded and integrated by the respective heat-sensitive adhesive layers. In addition, when used as an envelope, the folded flap portion is sealed even more firmly. In addition, there is no special restriction | limiting in the quantity and shape of the window-shaped hole P formed in the said folding | turning part.

  Further, in each of the above-described embodiments, substantially the entire surface of each leaf piece surface which becomes the outer surface side after completion of the envelope with a window is covered with various film sheets (see FIG. 11). However, the arrangement of the film sheet F is not necessarily limited except for the covering of the completely adhesive film sheet K. For example, as shown in FIGS. 33 and 34, the surface of the first leaf piece 1 is covered with a completely adhesive film sheet K, and the back surfaces of the second leaf piece 2 and the third leaf piece 3 are covered with various films. You may arrange | position so that a leaf piece may be covered with various films in the surface either front or back. In short, it is only necessary to arrange and cover various film sheets on either the front or back of each leaf piece so as to complement each other so as to prevent intrusion of water or the like.

  In each of the embodiments described above, the widths of the first leaf pieces 1, 41 and 71 are set shorter than the widths of the other leaf pieces, but there is no particular limitation. Since the first leaf piece is caught in another leaf piece, the width of the first leaf piece cannot be folded by jumping out from the other two leaf pieces when folded, or it cannot overlap with the third leaf pieces 3, 43 and 73 to form an envelope. It does not matter as long as it does not become impossible.
