Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing continuous envelopes into which variable information can be continuously written using a printing machine such as a line printer of an electronic computing device or a typewriter.

Conventionally, when manufacturing continuous envelopes that can print addresses, etc. on the surface of envelopes continuously using a printing machine of an electronic computing device or a typewriter, etc., and that can insert inserts, the unit constituting the continuous envelope paper A continuous envelope state in which a dry adhesive is applied along the three peripheries of either the upper envelope sheet or the lower unit envelope sheet, and then they are stacked and the three sides are glued, with an opening part on the end side along the continuous direction. At the same time, a continuous double-sided adhesive tape coated with a non-drying double-sided adhesive was attached to a release paper along one side of the opening side along the continuous direction to create a continuous envelope. The double-sided adhesive tape for sealing used at this time is usually used in a rolled state, so it is necessary to apply a release treatment such as silicone treatment to both sides of the release paper, which is difficult and extremely expensive. Ta.

In addition, since the tape is made into a tape, the thickness of the release paper and the adhesive are thick, and the entire tape is thick, so the length of the tape relative to the roll diameter is short, and the tape must be replaced frequently during envelope manufacturing. As a result, work efficiency was extremely poor and it was very inconvenient.

In addition, it was necessary to change the sealing form depending on the purpose of use of each type of envelope, but with conventional double-sided adhesive tape, it is possible to manufacture continuous envelopes that suit the purpose of use, just like adjusting the foot to a shoe. There wasn't.

Therefore, in view of the above points, the present invention not only allows continuous envelopes to be manufactured at low cost and with high production efficiency without using conventional double-sided adhesive tape for the sealing part, but also allows envelopes to be manufactured with various sealing forms depending on the purpose of use of the envelopes. The present invention provides a method for manufacturing continuous envelopes that can be easily obtained.

Next, an embodiment of the present invention will be explained based on the drawings.

In order to manufacture the continuous envelope 1 according to the present invention, as shown in FIGS. 1 and 2, the unit envelope bottom paper pieces 2 are continuous and the continuous envelope bottom paper 4 having the sealing part 3 is transported along the continuous direction. At the same time, a non-dry adhesive type adhesive 6 having constant tackiness is applied to the sealing part 3 of the unit envelope lower paper piece 2 by the adhesive applicator 5, and then the adhesive applicator is applied to the three surrounding areas of the unit envelope lower paper piece 2 7, a dry adhesive type adhesive 8 such as a hot melt type or an emulsion type is applied, and a continuous release paper 9 coated with a release agent such as silicone on one side is applied on the non-dry adhesive type adhesive 6 of the sealing part 3. Continuous transport is carried out while sequentially overlapping and temporarily adhering, and a continuous envelope upper paper piece 11 is formed by continuous unit envelope upper paper pieces 10 having the same length in the continuous direction as the previous unit envelope lower paper piece 2 and a width narrower by the width of the sealing part 3. While transporting the previous continuous envelope bottom paper 4, overlap the dry adhesive type adhesive 8 applied to the three areas of each unit envelope bottom paper piece 2 before this adhesive 8 dries. Then, while forming continuous envelopes, the sewing machine processing section 12 applies adhesive 8 around the unit envelope bottom paper piece 2 of the continuous envelope bottom paper 4 and the unit envelope top paper piece 103 of the continuous envelope bottom paper 11.
Separation perforations 13 are made at the boundaries of each unit envelope of the continuous envelopes glued together, and then the continuous envelopes 1 are manufactured by sequentially folding from the separation perforations 13.

Reference numeral 14 indicates a continuous paper transport hole. During the manufacturing process, the transport of the continuous envelope bottom paper 4 and the continuous envelope top paper 11 and the alignment of the unit envelope bottom paper piece 2 and the unit envelope top paper piece 10 are carried out through this paper transport hole. 14 is inserted into the pin of the tractor 15 to transport and align the positioning, thereby overlapping the unit envelope bottom paper piece 2 of the continuous envelope bottom paper 4 and the unit envelope top paper piece 10 of the continuous envelope top paper 11. It can be transferred without causing any misalignment.

Note that the adhesive applicator 5 is connected to the plate cylinder 1 as shown in FIG.
6. Depending on the purpose after sealing, i.e. whether the envelope is to be opened, whether the seal is strong or weak, whether it is partially glued, etc., an adhesive application pattern is applied intermittently, widely, or in spots. 17 coating plates are provided, and the adhesive coating device 7 is connected to the plate cylinder 1 as shown in the opening of FIG.
8 is provided with a coating plate having a U-shaped adhesive coating pattern 19.

In addition, the adhesive 6 is a material that can be easily bonded under pressure, and is always sticky under normal conditions when the main ingredient is polyisobutylene, natural rubber, chlorinated rubber, etc., and the adhesive agent is ester gum, phenolic resin, etc. It is a non-drying adhesive type adhesive having the following properties, which protects the adhesive 6 and maintains the adhesive state in the temporary adhesive state with the continuous release paper 9.

The dry adhesive type adhesive 8 is an adhesive that can be immediately bonded by drying at room temperature, or a so-called normal hot melt adhesive, emulsion type adhesive, etc. that cures and adheres at room temperature, and can be used to bond paper to paper. When adhering two sheets of paper, adhesive is applied to one sheet of paper, and before the adhesive dries, the other sheet of paper is placed on top of the other sheet of paper and the sheets of paper are adhered to each other.

Further, according to the present invention, as shown in FIG.
1 and the bottom paper of continuous envelopes 4, the unit has a width that is approximately the same size as the top paper of continuous envelopes 11, has a paper transfer hole 14' at one end, and has a portion of the top and bottom ends cut out. A continuous envelope containing one or more continuous envelope intermediate sheets, such as a continuous envelope 1' containing the continuous envelope intermediate sheet 17, by positioning a continuous envelope intermediate sheet 17 formed by continuous envelope intermediate sheets 16 in the paper flow direction. In this case, while applying the adhesive 8' to either the surface of the continuous envelope intermediate paper 17 on the paper transport hole 14' side or the back surface of the continuous envelope top paper 11 on the paper transport hole 14 side, It is manufactured in the same manner as described above.

In addition, in the above-mentioned continuous envelope 1', a copy transfer agent 18 such as carbon ink is provided at a predetermined location on the back surface of the continuous envelope top paper 11 so that copy printing can be performed from the front surface of the continuous envelope top paper 11 to the continuous envelope intermediate paper 17. Alternatively, a carbonless copying system may be used in which a coloring agent capsule is coated on the back side of the top paper 11 of the continuous envelope.

In FIG. 4, the perforations 20 provided in the continuous envelope interlayer paper 17 are cut-off perforations for cutting out the unit envelope interlayer paper piece 16 from the envelope after opening the envelope.

The continuous envelopes 1, 1' manufactured as described above are separated into unit envelopes from the perforation 13 after the desired printing is continuously applied to the predetermined printing field on the surface of the envelope using a printing machine of an electronic computing device or a typewriter. After separating each part, sealing part 3
Insert the contents from the side, peel off the continuous release paper 9 of the sealing part 3, and then attach the adhesive 6 side of the sealing part 3 to the upper paper piece 10 of the unit envelope.
The sealing part 3 is folded and pressed against the upper paper piece 10 of the unit envelope so as to be in contact with the upper paper piece 10, and the envelope is sealed with an adhesive 6.Then, the sealed envelope is sent by mail or the like.

As described above, in the continuous envelope manufacturing method of the present invention, a dry adhesive type adhesive is applied around the blank area of the unit envelope piece area, and a non-dry adhesive type adhesive is applied to the sealing part. The adhesive around the three envelopes can be glued immediately after overlapping the envelope pieces, making it easy to manufacture accurate envelopes without shifting the adhesive parts, and the adhesive in the sealing part remains constant until sealing. Since it has adhesive properties, it can be easily sealed.

Also, instead of using double-sided adhesive tape on the sealing part, a non-drying adhesive is applied directly to the sealing part of the continuous envelope paper.
Since a release paper is applied to the top of the tape, the adhesive application pattern on the sealed part is not just a continuous straight line along the continuous direction as with conventional double-sided adhesive tapes, but can be applied to the necessary parts of the sealed part according to the purpose after sealing. It can be provided intermittently, with a wide width, or in spots, or it can be provided intermittently on the perforation line, and the width of the release paper can be freely selected. It is also possible to obtain open envelopes that are easy to peel and that remain partially unsealed when sealed, envelopes that are strongly sealed, envelopes that are partially adhesive, etc. Also, continuous folding from the tear-off perforation can be performed smoothly. It is very convenient and can be done at a low price.

In addition, it is possible to use a release paper that has a release agent on only one side, and since it uses a release paper that is not coated with adhesive, the roll diameter of the release paper can also be increased and continuous operation is possible. This is a very useful method for manufacturing continuous envelopes because it can be easily manufactured.
