The width dimensions of 1, T ', and T2 are appropriately set according to the type and size of the printed matter. For example, the width of the binding portion T has a dimension of about 25 mm in a normal hanging calendar, and the width of the first thermocompression bonding portion T1 and the second thermocompression bonding portion T2 is approximately 3 mm. It has dimensions of ｍｍ7 mm. Q is a hanging hole for hanging a multi-leaf print on a hook such as a nail attached to a wall or a pillar in the room; This is a perforation for cutting 1 out.

FIG. 2A shows an embodiment of a main part of the above-mentioned apparatus for producing a bi-leaf print, wherein 2 is a base portion, 3 is a lower heating means, 4 is an upper heating means, and 5 is a pressurizing means. Means 6 are a heat pressure member and a holding member 7. A plurality of printed paper sheets 1 are stacked on the base portion 2 and set in a state where the binding portions T are aligned. The lower heating means 3 is disposed in front of the base 2, and the upper surface thereof is
Is the same plane as the upper surface of. The lower heating means 3 and the upper heating means 4 are heated by electric heat or a suitable heat medium. The upper heating means 4 is arranged above the lower heating means 3, and is configured to be pressurized and lowered toward the lower heating means 3 by a pressing means 5 such as a hydraulic press. The heat-pressing member 6 is formed by arranging two strip-shaped plate members side by side at a predetermined interval, and is oriented so that the width direction thereof is up and down. It is in contact with the heating means 4 and is heated by the upper heating means 4. The heat and pressure member 6 may be integrally fixed to the upper heating means 4 or both may be integrally formed. Heat pressure member 6
Is protruded from the lower surface of the holding member 7 by the pressing margin S. The pressurizing means 5 may be configured to increase the pressure of the lower heating means 3 toward the upper heating means 4.

Next, a method of manufacturing a multi-leaf print using the above-described apparatus will be described. First, as shown in FIGS. 1A and 1B, a printing ink for thermocompression (heat press) is applied to at least each thermocompression bonding portion T1 and T2 of the upper binding portion T of the stacked paper leaf 1. Printing is performed in advance, or an adhesive such as hot melt is applied in advance. As the printing ink for thermocompression bonding, for example, it is preferable to use a SMX thermocompression ink (manufactured by Toyo Ink Mfg. Co., Ltd.) which is as thin as possible, but is not limited to this.

Subsequently, as shown in FIG. 2A, a plurality of sheets 1 stacked on the base portion 2 and aligned with the binding portion T are moved in the direction of the arrow, and the binding portion T is moved. It is located directly below the heat pressure member 6. In this state, as shown in FIG. 2B, the pressurizing means 5 is operated to lower the hot-pressing member 6 toward the paper sheet 1 to heat-press the binding portion T. Since the heat-pressure member 6 is pre-heated by the upper heating means 4, the first thermocompression bonding portion T1 and the second thermocompression bonding portion T2 are pressurized as shown in FIGS. 2C and 1C. Then, these portions T1 and T2 are heated (for example, 120 to 13).
(0 ° C.), and are thermocompression-bonded by crimping forces P1 and P2, respectively, and bound.

[0013] The hot pressing time is 2 in the case of a normal calendar.
It takes only ~ 3 seconds, which is extremely shorter than the conventional 6-7 seconds. As soon as the hot pressing operation is completed, the hot pressing member 6 is pulled up.
At this time, the hot-pressed sheet 6 is made of a material having high releasability such as aluminum metal.
Can be prevented from rising. When the heat-pressing member 6 is pulled up, the processed multi-leaf printed matter is taken out, the next laminated paper leaf 1 is inserted, and the above operation is repeated.

FIG. 1D shows a state in which a plate-shaped reinforcing paper F whose bonding surface has been preliminarily pasted is preliminarily attached to the uneven surface of the binding portion T before the hot-pressing operation. FIG. 1E shows another embodiment in which the binding portion T is reinforced by being joined at the same time as the heat and pressure operation by the pressure member 6, and FIG.

) -Shaped reinforcing paper F ′ on the outer peripheral surface of the binding portion T.
This shows still another embodiment in which the binding portion T is reinforced beforehand by applying the heat and pressure to reinforce the binding portion T.

FIG. 3 shows a state in which a perforation cutter 8 is attached to the holding member 7 and the perforation R (see FIG. 1) is processed simultaneously with the hot pressing operation by the hot pressing member 6. This is an example.

FIG. 4A shows one of the two thermal pressure members 6.
Particularly, still another embodiment in which a depression 6a is formed at the lower end of the heat-pressure member 6 on the inner side (left side in FIG. 3) of the paper sheet 1 is shown. When heat is applied by the heat-pressing member 6, a corrugated non-heat-pressure portion T ″ is formed on the plurality of stacked sheets 1 as shown in FIG. Since T ″ has the same height as the non-thermocompression bonding part T ′,
When the reinforcing paper F or F 'is joined, the edge thereof is
It can be joined also to this corrugated non-heat-pressure portion T ″, and as a result, there is no possibility that the reinforcing paper F or F ′ will be rolled up and impair the appearance. ,
It is not limited to this.

FIGS. 5 (A) and 5 (B) show that the reinforcing paper G is processed into irregularities, and one side of a bi-leaf print H such as a calendar is adhered to the same to substantially form the structure shown in FIG. 13 shows another embodiment having the same structure. The reinforcing paper G may be one obtained by laminating a plurality of paper sheets and thermocompression bonding in addition to one thick paper.

In the above embodiment, a calendar is taken as an example of a multi-leaf printed matter, but the present invention is not limited to this, and any printed matter may be used as long as a plurality of printed sheets are overlapped and bound. .

[0019]

1) Since the width and area of the crimped portion are smaller than those of the conventional thermocompression bonding, it is not necessary to apply a large pressure.
As a result, a device such as a press can be provided at a small size and at low cost. 2) Since the width and area of the heating portion are smaller than those of the conventional thermocompression bonding, less heating energy is required, and the heating device can be provided in a small size and at low cost. 3) The pressing time is shorter than that of the conventional thermocompression bonding, the work efficiency is improved, and the cost is reduced.
