Description

[Detailed description of the invention] The present invention relates to a method for manufacturing forms such as cards and booklets.

Conventionally, high-speed printing machines have been used to print the required data on continuous forms, and then the continuous forms are separated into form bodies to obtain forms such as cards and booklets on which a large amount of the necessary data is printed. It is.

At that time, as a method to separate continuous forms into individual forms, 1)
A method in which perforations are carved in advance at the boundaries between individual forms, and after printing, the continuous forms are separated along the perforations and separated into individual forms, (2) perforations are carved in advance at the boundaries between individual forms, After printing, the continuous form paper is cut along the perforations with a pair of knives that reciprocate up and down, separating the forms into individual forms, or (3) perforations are carved in advance at the boundaries between individual forms, and the paper is cut after printing. A method is used in which a burster consisting of a low-speed roller, a high-speed roller, and a cutter tears the continuous form paper along the perforations and separates it into individual forms.

However, the separation methods described above not only have the common drawback that perforation fluff occurs at the point where the perforation is cut, detracting from the beauty of the form, but each method also has the following drawbacks. First of all, in the first method, the tensile strength changes due to differences in the paper strength of the paper and the difference in the tie and cut ratio of the perforation, so it may take some getting used to when first handling the work of manually cutting along the perforation. There are drawbacks that make it necessary. That is, each time the work content differs, it is necessary to get used to it when handling it for the first time. Next, the second method has the following problems: (i) The processing speed is limited by the vertical movement speed of the knife and is inefficient.

(ii) It is difficult to maintain sufficient finished dimensional accuracy.

There are drawbacks such as. Next, the third method has the following: (i) If exact document dimensions are required, the perforations will be outside the standard.

(゛) The sound of paper breaking when cutting and separating is loud.

(iii) As the thickness of the form increases, it becomes difficult to tear it apart.

In addition, in addition to the method described above, continuous forms are placed on a continuous base paper, and a glue margin is continuously provided on the form body, and a plurality of individual forms with perforations carved on the boundary between the form body and the glue margin are placed on a continuous base paper. After printing on the surface of each form body of continuous forms arranged in a single row or multiple rows at intervals in the longitudinal direction and pasting the back side of each single form's adhesive sheet to a continuous base paper, each form body is pasted with adhesive sheet. The method used is to separate the documents along the perforations and separate them into individual forms.

However, this method has the following problems: (1) perforation fluff occurs from the location where the sewing machine cuts, spoiling the appearance of the form;

(Ii) The perforations between the glue margin and the form body require a tensile strength that can withstand processing by the friction roller in the printing device, so there is a limit to the ease with which they can be cut out by hand.

In addition, if high tensile strength is required for the mechanical suitability of the printing device,
The continuous base paper is also more likely to be destroyed at the sprocket hole, folding perforation, etc. due to the force when separating the form body from the adhesive. (Iiii
) Since the lower side of the form body is open and there are perforations between the glue margin and the form body, it is easy to turn over, so when using a backfeed type printing device, the form turns over during backfeed and gets stuck in the device, making it impossible to transport. It's easy to become.

There are drawbacks such as.

As a result of research to solve the above-mentioned drawbacks, the present invention has been developed by arranging a plurality of forms in a single row or multiple rows on a continuous base paper at intervals in the longitudinal direction of the continuous base paper, and After printing on the surface of each continuous form with a hot-melt adhesive on the continuous form, the hot-melt adhesive is heated and the hot-melt adhesive is melted to separate the form from the continuous form. It was found that the above-mentioned difficulties could be resolved by adopting this method.

The present invention has been made based on this knowledge.

That is, the gist of the present invention is to arrange a plurality of forms in a single row or multiple rows on a continuous base paper at intervals in the longitudinal direction of the continuous base paper, and to apply a hot melt adhesive to a part of the back side of each form. A printing device prints on the surface of each continuous form adhered to the continuous base paper, and then heats to melt the hot melt adhesive and separate the form from the continuous base paper. It's a method. Below, regarding the present invention,
This will be explained in detail with reference to the drawings.

Figures 1 and 2 show a continuous form 5a used in the present invention.
FIG. 1 is a perspective view, and FIG. 2 is a perspective sectional view taken along the line A--A shown in FIG.

At intervals on the continuous base paper 1 in the longitudinal direction of the continuous base paper 1,
A plurality of cards 2 are arranged in a line, and a part of the back surface of each card 2 is adhered to a continuous base paper 1 by a hot melt adhesive layer 3.

Here, the hot melt adhesive layer 3 is formed in the shape of two strips in the longitudinal direction of the continuous base paper 1. Further, 4 indicates a sprocket hole. FIG. 3 shows a continuous form 5b in which a hot melt adhesive layer 3 is provided horizontally at a position corresponding to the top of the card 2.

Furthermore, FIG. 4 shows a continuous form 5c in which the hot melt adhesive layer 3 is provided in the form of spots.

After the continuous forms 5a as shown in the first and second figures are printed by the printing device 6 as shown in the fifth figure, they are passed through the heating device 10 of the separating device 14.

The heating device 10 consists of a hot plate 7, a thermistor 8, and a nichrome wire 9, as shown in FIG. The hot plate 7 is a continuous base paper 1
directly contacts the back surface of the continuous base paper 1 and supplies heat to the hot melt adhesive layer 3 through the continuous base paper 1 to heat and melt the hot melt adhesive layer 3. The nichrome wire 9 heats the hot plate 7. The thermistor 8 detects the temperature of the hot plate 7. The thermistor 8 is connected to a temperature adjustment circuit (not shown) consisting of a Wheatstone bridge and an electromagnetic relay, and is configured to always maintain a set temperature. ing.

As the hot melt adhesive layer 3 is heated and melted by the heating device 10, the adhesive strength is extremely reduced and the card 2 becomes easy to separate. Next, when the tapered wedge 11 is inserted between the card 2 and the continuous base paper 1, the card 2 is easily separated from the continuous base paper 1 as shown in FIG. The separated cards 2 are discharged to a card discharge section 12, while the continuous base paper 1 is folded in a zigzag manner and discharged to a continuous base paper discharge section 13. In the method of the present invention described above, when a paper with better oil absorption than the paper of the card 2 is used as the paper of the continuous base paper 1, the melted hot melt adhesive 3
Most of the hot melt adhesive is impregnated toward the continuous base paper 1, and a small amount is impregnated onto the back side of the card 2, thereby reducing its adhesive strength. can be separated from

The method of the present invention described above can be applied not only to the production of cards but also to the production of booklets.

That is, as shown in Figure 8, a continuous form 5d in which a plurality of booklets 15 are adhered to a continuous base paper 1 with hot melt adhesive 3 is used in place of the card 2, and according to the method of the present invention described above. A plurality of booklets 15 can be produced.

Next, although the continuous forms shown in Figures 1 to 4 and 8 are provided with a sprocket hole 4, this is not necessarily necessary, and the continuous form 5e shown in Figures 9 and 10 does not have a sprocket hole. In that case, the paper feed speed can be adjusted by detecting perforations, 0CR marks, etc. provided at regular pitches, and correcting the speed based on the detection results. can.

Next, in the method of the present invention described above, the following heating device may be used instead of the heating device described above. The heating device 18 shown in FIG. 11 has a press rotating disk 16 with a width equal to or wider than the width of the hot melt adhesive layer and a heating element with the same width as the press rotating disk 16, and has a surface temperature of 100°C. The temperature was maintained between 200°C and 200°C.

It consists of a heating rotating disk 17. The heating rotary disk 17 is positioned opposite to the area on the back of the card where the hot melt adhesive is applied. This device makes it possible to heat the hot melt adhesive layer extending in the longitudinal direction of the base paper. The heating device 21 shown in FIG. 12 includes a breath roll 19 and a heating roll 20 having a heating element and whose surface temperature is maintained at 100°C to 200'C.

The heating device 23 shown in FIG. 13 consists of a xenon lamp 22.

Flash exposure is applied to the back surface of the base paper using a xenon lamp 22, and the adhesive is heated and melted by the radiant heat. At this time, in order to increase heat absorption into the base paper, it is desirable to provide a black printed layer 24 containing carbon black in the same shape as the hot melt adhesive application pattern on the back surface of the base paper. that's all,
As described in detail, according to the present invention, there is no need for a step of separating along perforations, so (1) separation into individual forms can be performed with high efficiency.

(Ii) The appearance of the product is good.

(Ji) The product can be finished with sufficient finishing dimensional accuracy.

(■) No noise is generated during separation work.

(v) Separation work can be easily performed even when the form is thick. The following effects can be achieved.
