Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for continuously forming a letter V-folded or Z-folded from roll paper in the width direction thereof.

[0002]

2. Description of the Related Art Conventionally, this kind of sealed letter forming method is applied to a roll paper before being folded into a V-shape or a Z-shape in a process before folding the roll paper into a V-shape or a Z-shape. On one side facing each other, special glue such as pressure-sensitive glue that does not adhere in the normal state, for example, pressure-sensitive glue that adheres by applying pressure, is applied in a predetermined pattern in advance,
Then, necessary printing is performed, and this glued, and if necessary, the printed roll paper is supplied to a folding device to fold it into a V-shaped or Z-shaped fold, and then adhered by applying pressure to a predetermined size. She was cutting and creating a letter.

[0003]

In the above-mentioned conventional letter-making method, glue is applied to a predetermined pattern for each unit letter in advance. It had to be performed, and the production efficiency was poor in the process. In addition, in order to create a sealed letter from the roll paper on which the glue is applied in advance, the roll paper fed from the sheet feeding position is folded at a predetermined position, and then cut into sealed letters one by one at the predetermined position. As described above, the roll paper must be aligned in the vertical direction, so that the roll paper must be synchronously fed by a pin tractor. For this reason, there was a problem that the paper feeding speed of the roll paper could not be increased, and the production efficiency was poor. Further, in the above-mentioned conventional method, a special paste such as a pressure-sensitive paste must be used, and this paste is expensive, and there is a problem in terms of cost in addition to the above-mentioned inefficiency in production.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, and makes it possible to create a sealed letter with extremely high efficiency and to reduce the cost by using inexpensive glue. It is an object of the present invention to provide a method for producing roll paper, in which roll paper is supplied at a predetermined tension, and the roll paper is folded in a V-shape or a Z-shape in the width direction. Immediately before each of the folding steps, one inner surface of each of the folded pieces was glued with a glue pattern serving as an edge of a sealed letter, and after the folding step, cut at a predetermined position, pressed and discharged.

The roll paper fed from the paper feed unit is glued in a predetermined pattern and then folded into a V-shaped or Z-shaped fold.

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a device for creating a letter V-folded or Z-folded from the roll paper 1 in the width direction thereof. In the drawing, reference numeral 2 denotes a paper feeding unit, 3 denotes a folding unit, 4 denotes a processing unit,
Reference numeral 5 denotes a stacker section, which is sequentially arranged in the running direction of the roll paper 1.

The paper feed unit 2 supports the roll paper 1 and
The paper is fed while maintaining a predetermined tension. The folding unit 3 includes a first plow folding device 6a that folds the roll paper 1 fed from the paper feeding unit 2 in a V-shape in the width direction, and a downstream of the first plow folding device 6a in the traveling direction of the roll paper 1. Roll paper 1 which is arranged on the
A second plow folding device 6b, which is a V-fold of one folded piece in the reverse direction to result in a Z-fold, and each plow folding device 6a is located upstream of each plow folding device 6a, 6b. 6
It has first and second gluing devices 7a and 7b for applying glue to one inner surface of a folding piece to be folded at a and 6b, and to a portion to be an edge of a sealed letter.

The processing section 4 includes a cutting device 8 for cutting the rolled paper 1 folded in a V-shape or a Z-shape for each unit envelope, and a pressing device 9 for pressing and sealing each cut envelope.
And The stacker section 5 includes a feed belt 10, a separating roll 11, and a stacker 11a.

Next, a description will be given of a method of creating a Z-folded letter using the above-described apparatus. The roll paper 1 of the paper feed unit 2 is supplied with a predetermined tension by a group of rollers provided in the folding unit 3. Then, in the folding section 3, the first gluing device 7a first forms the third side of the folded piece 1a in the width direction 1/3 of the roll paper 1 on the inner side surface of the folded piece 1a along the edge of the letter as shown in FIG. One glue pattern 12a is sequentially applied. The glue application pattern is formed in a U-shape with the first fold line 13a side of the roll paper 1 opened.

Next, as shown in FIG. 4, the first plow folding device 6a folds the sheet along the first planned folding line 13a.

Next, as shown in FIG. 4, the second gluing device 7b folds the second glue pattern 12b into a folded piece 1b of the other one-third in the width direction of the roll paper 1 to be Z-folded. Is applied to a position corresponding to the first glue pattern 12a in a U-shape with a shape along the edge of the sealed letter and with the second fold line 13b side open.

Next, as shown in FIG. 5, the second plow folding device 6b folds the sheet along the second planned folding line 13b.

After that, the folding unit 3
Then, the roll paper 1 folded in the Z-shape is cut into unit sealed letters, and the folded pieces 1a and 1b are pressed by the pressing device 9 to be pressed against the folded body piece 1c to form a sealed letter. These sealed letters are sequentially accumulated in the stacker unit 5.

As described above, the letter folded in the Z-shape is continuously created. Then, predetermined information is printed on the inner area portion of each sealed letter as required in the previous process of the roll paper 1. In this case, the printing unit, the gluing unit, the folding unit, and the cutting unit need to be aligned vertically and horizontally.

In the case of the V-shaped folding, one of the gluing device and the plow folding device is used, and the roll paper 1 is folded at the center thereof.

The glue applied by the gluing devices 7a and 7b is an ordinary aqueous glue.

[0017]

According to the present invention, since the paper can be supplied while tension is applied to the roll paper 1, a sealed letter can be created at a high speed without using a pin tractor.

In addition, since the gluing is performed immediately before folding, it is not necessary to perform this glue applying operation on the roll paper in a separate process in advance, and the efficiency of forming a sealed letter can be improved in the process. In addition to this, an inexpensive aqueous glue can be used for the glue, and the use of the aqueous glue allows the use of a general pattern greasing device or a gluing head or a nozzle type for this gluing. It is possible to reduce the cost of creating this type of sealed letter. The glue pattern may be applied in a number of dots with a pitch of several mm along the glue pattern in addition to the glue being applied linearly. In the case of a general patterning machine, the effect of economical efficiency and versatility can be expected, and in the case of the nozzle system, the effect of reducing the equipment and size can be expected.

Further, when creating a sealed letter from roll paper,
By using printing or a roll of paper rolled up after printing, a sealed letter can be created in one process by printing the sealed letter off-line, or in some cases online.
