  Since the sheet for folding sealed letters described in the cited references described above is written in a one-to-one correspondence with each sheet and finished in a folded sealed letter, there is no possibility that the information of others is mixed by mistake. Moreover, since it is finished in a sealed letter by folding, there is an advantage such as saving the trouble of enclosing and sealing. However, protruding sealing edges that require special processing, adhesive application for sealing, cutting machine processing for tearing off the sealing piece when opened, release agent application processing for easy peeling of the adhesive part, two-row sewing machine It requires complicated and time-consuming processing such as unsealing means by eyes, and it is expensive even though it has the advantages described above.

  In view of the above problems, the folding envelope of the present invention has a plurality of pieces of paper in one envelope, information contained in another person, and misencapsulation of other people's information. The booklet is bound in a double-spread form after opening, making it easy to check information and attracting the recipient's interest. Moreover, the manufacturing method of the folding sealed letter of this invention aims at providing the folding sealed letter which can suppress an increase in cost by minimizing the special process at the time of making a sealed letter.

  In order to achieve the above-mentioned object, the folding sealed letter of the present invention is a longitudinal unit in which a set of unit sheets made up of a plurality of leaf pieces connected in the horizontal direction via the vertical folding line passes through the horizontal folding line. Folded sealed paper connected in two sets to each other is folded from the longitudinal fold line, and finally folded in half from the lateral fold line, and each opposing leaf piece is connected via a pseudo-adhesive medium. By opening the lower edge formed by the horizontal fold line and expanding the adhesive, the open side edge of any pair of upper and lower two leaf pieces is bonded so as not to be peeled. It is characterized by being in a bookbinding state.

  Note that the folded letter of the present invention is closed in a bag shape because the lower edge becomes a fold line portion that is largely folded in half. Accordingly, the recipient needs to open the lower edge after cutting it using a cutting tool such as a scissors or a cutter. If a breaking means such as a cutting sewing machine is provided along the lower edge of the overlapping leaf pieces in advance in order to save time and effort, it can be broken and opened manually without using a cutting tool.

  Also, a breaking means such as a cutting sewing machine is formed on the lateral fold line of the lower edge, and the cutting machine formed on the fold line is broken by hand without using a cutting tool like the opening means. And can be opened. In this case, chips are not generated at the time of breakage, which is more convenient.

  Further, in order to save all the troubles at the time of opening, it may be possible to reach the recipient's hand in a state where the lower edge is excised and opened before posting.

    Furthermore, in order to achieve the above object, according to the method of manufacturing a folded letter of the present invention, a unit sheet composed of a plurality of leaf pieces connected in the horizontal direction via a vertical fold line is provided via a horizontal fold line. Folded sealed paper sheets connected in two vertical directions are folded from the vertical fold line, and finally folded in two from the horizontal fold line, and the release side of any pair of upper and lower two-leaf pieces A method for manufacturing a folded sealed letter which is in a double-sided bookbinding state after being opened by bonding the edges so as not to be peeled off, a sheet feeding step for feeding out the sheet on which the folded sealed letter paper is printed, and Forming a pseudo-adhesive medium on the planned pseudo-adhesive surface and forming a complete adhesive medium on the bookbinding portion, and folding printed on the sheet on which the adhesive medium is formed A cutting process for cutting off the vertical margins of the sealed paper, and a sheet on which the folded sealed paper with the blanks printed is folded from the vertical folding line so that the pseudo-adhesive media and the completely-adhesive media face each other. One folding process, a cutting process that cuts the folded sealed paper before and after the sheet on which the folded sealed paper folded from the vertical fold line is printed, and finishes it into individual folded sealed paper, and individually finished folding The second folding step of folding the sealed paper from the horizontal fold line into the final folded form, and the pseudo-adhesive planned surface of the folded sealed paper folded in the final form are releasably adhered, and the bookbinding portion cannot be removed. It is characterized by comprising an adhesion step of adhering to the substrate.

  In addition, in order to save all the troubles when opening the recipient, if a cutting step for cutting off the lower edge that is closed and sealed in the bag shape of the folded envelope is arranged after the bonding step, the lower edge is already present. Since it is in a state of being cut and released, the recipient can open it as it is, and it is convenient because no chips are generated.

  Furthermore, in the manufacturing method of the folded envelope, the cutting step and the cutting step are performed first, and after the folded sealed paper is cut out, the first and second folded steps are passed at once, and then sent to the bonding step to manufacture the folded seal. It doesn't matter.

  Furthermore, there is no limitation on the formation timing of folding means such as a folding sewing machine or folding line formed on the vertical folding line. For example, it may be formed on either the upstream side or the downstream side of the adhesive medium forming step. Further, it may be formed stepwise on both the upstream side and the downstream side. Further, a folded sealed letter paper in which folding means is previously formed in the feeding process may be placed, and in this case, the folding means forming process can be omitted. In addition, you may form a folding means also in the fold line of a horizontal direction.

  Each process in these manufacturing methods may be performed in a consistent continuous process, or may be performed by transferring the folded sealed paper for each process using an individual dedicated machine.

As the material used for the folded letter of the present invention, for example, normal paper such as high-quality paper, matte paper, and coated paper, synthetic paper, non-woven fabric, or a resin film sheet can be preferably used. And the pseudo-adhesive medium used for the pseudo-adhesion for adhering the folded opposing surfaces to each other is categorized into the following three types.
1) Post-glue system A pseudo-adhesive film is formed by applying pseudo-adhesive UV varnish to the planned pseudo-adhesive surface of the printed paper. When the pseudo-adhesive coatings are opposed to each other and subjected to pressure or heating / pressurization treatment, they are detachably bonded. Some have an emulsion type adhesive.
2) Tip-glue method A pseudo-adhesive medium composed mainly of synthetic rubber or natural rubber is applied to and impregnated on the planned pseudo-adhesion surface of the paper before printing. After drying, printing and printing are performed, and when the pseudo-adhesion planned surfaces are made to face each other and subjected to pressure treatment, they are detachably bonded.
3) Film system A pseudo-adhesive film sheet is coated on the pre-printed pre-adhesive surface of the printed paper, and the pseudo-adhesive film sheet is opposed so that it can be peeled when pressed or heated / pressurized. To do. There are two types of film systems: a full-face bonding system in which both surfaces of the facing surface are coated in advance, and a sandwiching system in which a film system that is preliminarily bonded between the facing surfaces of the folded paper is sandwiched and bonded.

  Further, the folding sealed letter of the present invention is obtained by folding one folded letter sheet vertically and horizontally, and folding means such as perforations and fold lines formed in the fold line are the manufacturing process of the folded letter. Done in. In addition, the formation of the pseudo-adhesive medium for sealing and the formation of the complete adhesive medium for bookbinding are automatically performed during the manufacturing process of the folded letter as in the case of the folding means.

  The folding sealed letter of the present invention is initially folded from the vertical folding line, and then the leaf pieces grouped vertically by the horizontal folding line are finished from the horizontal folding line to a sealed letter size. Then, an arbitrary pair of upper and lower leaf pieces is selected at the time of folding from the fold line in the lateral direction, and the edges on the open side of the opposed inner surfaces are bonded together so as not to be peeled off. By doing so, the release-side edge bonded in a non-peelable manner becomes the bookbinding portion.

  Since the folding sealed letter of the present invention is finally folded from the lateral folding line, the folded side is closed like a bag. In addition, although the said edge | side required in an Example etc. is expressed as a lower edge edge, you may make an upper edge edge into a bag-like closed edge by the layout of the design described. When the design is laid out in the landscape direction, either the left or right side becomes a bag-like closed side.

Since the folding seal of the present invention describes the information on a single sheet in a one-to-one correspondence and finishes it into a folded seal, it collects a plurality of separate pieces of paper on which personal information is printed and collects the information of others that occurs when sealed. There are no serious accidents such as misencapsulation.
In addition, after opening, the book is bound in a double-spread form, so that it is easy to check the information, which attracts the recipient's interest.
Furthermore, in the method of manufacturing a folded letter of the present invention, since troublesome work processes including the process of forming various adhesive media and the process of forming folding means can be performed automatically, even an amateur can produce a large number of folded letters in a short time. become. Of course, it is possible to produce a folded letter very easily even if it is carried out by an operation by an individual dedicated machine.
