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 used for sealing at this time is normally used in rolled form, 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. there were.

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

Therefore, in view of the above points, the present invention provides a continuous envelope that can be manufactured at low cost and with good manufacturing efficiency by using the same adhesive applied to the periphery of the envelope and the adhesive applied to the sealing part. A manufacturing method is provided.

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

In order to manufacture continuous envelopes 1 according to the present invention, as shown in FIG. 1 and FIG. While doing so, a non-dry adhesive type adhesive 6 having constant tackiness is applied to the area around the bottom of the unit envelope lower paper piece 2 and the sealing part 3 by the adhesive coating device 5, and then on the adhesive 6 of the sealing part 3. Continuous release paper 7 coated with a release agent such as silicone on one side
are sequentially overlapped and temporarily bonded while being continuously transported, and a unit sealing upper paper piece 8 having the same length in the continuous direction as the previous unit envelope lower paper piece 2 and having a narrower length at the width of the sealing part 3 is formed. While transporting the continuous envelope top paper 9, it is overlaid and glued onto the adhesive 6 applied around the white area of each unit envelope bottom paper piece 2 of the previous continuous envelope bottom paper 4, and is machine-sewn while forming a continuous envelope. In section 10, a tear-off perforation 11 is made at the border of each unit envelope piece of the continuous envelope, the peripheries of the lower unit envelope piece 2 of the lower continuous envelope sheet 4 and the upper unit envelope piece 8 of the upper continuous envelope sheet 9 are glued with the adhesive 6. , then cut away perforation 1
Continuous envelopes 1 are manufactured by sequentially folding envelopes 1.

Reference numeral 12 denotes a continuous envelope paper transport hole, and the continuous envelope bottom paper 4 and continuous envelope top paper 9 are transported by inserting the paper transport hole 12 into a pin of a tractor 13 during the manufacturing process. Unit envelope bottom paper piece 2 of continuous envelope bottom paper 4
The overlapping of the unit envelope top paper piece 8 of the continuous envelope top paper 9 is as follows.
It can be transferred without causing any misalignment.

Note that the adhesive applicator 5 is connected to a plate cylinder 14 as shown in FIG.
A coating plate with an adhesive coating pattern 15 is provided on the surface of the adhesive 6, and the adhesive 6 is a material that can be easily bonded by pressure, and the main ingredients are polyisobutylene, natural rubber,
It is a non-drying adhesive that is always sticky under normal conditions, containing ester gum, phenol resin, etc. as adhesion aids such as chloride rubber, and when applied between sheets of paper. The adhesive 6 provided in the sealing part 3 has a material on the upper surface that protects the adhesive 6 and maintains its adhesive state in the temporary adhesive state with the continuous release paper 7. It is.

Further, according to the present invention, as shown in FIG. 4, there is a width approximately the same as that of the continuous envelope top paper 9, and a paper transfer hole 12' is provided at one side end. Continuous envelopes 1' containing continuous envelope intermediate sheets 17 can also be constructed by positioning continuous envelope intermediate sheets 17 formed by connecting unit envelope intermediate sheets 16 in which the upper and lower ends are partially cut out in the paper flow direction. The number of continuous envelope intermediate sheets 17 may be one or more.

In addition, in the above-mentioned continuous envelope 1', a copying transfer agent 18 such as carbon ink is provided at a predetermined location on the back surface of the continuous envelope top paper 9 so that copy printing can be performed from the front surface of the continuous envelope top paper 9 onto the continuous envelope intermediate paper 17. Alternatively, a carbonless copying system may be used in which a coloring agent capsule is applied to the back surface of the continuous envelope top paper 9 and a coloring agent is applied to the receiving surface of the continuous envelope intermediate paper 17.

In FIG. 4, the perforations 19 provided in the continuous envelope interlayer paper 17 are cut-off perforations for separating the unit envelope interlayer paper piece 16 from the envelope after the envelope is opened.

In addition, in the case where the continuous envelope intermediate paper 17 is provided, the surface of the continuous envelope intermediate paper 17 on the paper transfer hole 12' side,
Alternatively, an adhesive 6' is provided on either side of the back surface of the continuous envelope top paper 9 on the paper transport hole 12 side.

The continuous envelope 1 manufactured as described above is manufactured by printing the desired characters continuously on the predetermined printing field on the surface of the envelope using a printing machine of an electronic computing device, a typewriter, etc., and then separating each envelope from the perforation 11. After separating, insert the contents from the sealing part 3 side, peel off the continuous release paper 7 of the sealing part 3, and then place the sealing part 3 on the unit envelope so that the adhesive 6 side of the sealing part 3 is in contact with the paper piece 8 on the unit envelope. The envelope is folded toward the paper strip 8 side, pressed, and sealed with adhesive 6, and then the sealed envelope is used for mailing or the like.

As described above, in the continuous side tube manufacturing method of the present invention, adhesive is applied to the three peripheries of the envelope and the sealing part using the adhesive coating plate of the same adhesive coating unit to manufacture the continuous envelope. Not only can the equipment be simplified without installing a separate adhesive applicator, improving work efficiency, but also the non-drying adhesive can be applied directly to the sealed portion of continuous envelope paper instead of using double-sided adhesive tape. Since a release paper is applied on 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 made in an intermittent configuration with breaks on the perforations, and the width of the release paper can be freely selected, making it easy to remove The paper is easy to peel off, the envelope can be partially opened, and continuous folding can be performed smoothly from the tear-off perforation, making it very convenient and inexpensive.

In addition, it is possible to use a release paper that has a release agent on only one side, and because it uses a release paper that is not coated with adhesive, the roll diameter of the release paper can also be increased, allowing continuous operation. The envelopes are easy to manufacture and very convenient.
