[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calendar that can be peeled off.

[0002]

2. Description of the Related Art A conventional calendar that can be peeled off is:
The upper part of each paper was overlapped, and the upper part was stopped using a metal fitting called a metal fitting or a W-ring, and a perforation was made in a part to be peeled off. Further, its planar shape is also limited to a square shape.

[0003]

[Problems to be Solved by the Invention] Therefore, a mounting process of metal fittings is required, and the remaining metal fittings are turned into industrial waste, which makes it difficult to dispose, and leads to wasteful consumption of resources. In addition, since the metal fittings are used, molding processing cannot be performed after the metal fittings are attached, and the shape of the metal fittings must be limited. Furthermore, the conventional perforations have a large pitch, and it has been difficult to peel them off neatly. The present invention solves such a problem, and, in short, provides a calendar that can be easily peeled off without using metal fittings.

[0004]

SUMMARY OF THE INVENTION Under the above-mentioned problems, the present invention relates to a method of superimposing a plurality of sheets on which the date and day of each month are printed.
The upper part is glued to the binding part, and the remaining part is
A calender with a cut-off part that can be peeled off by inserting a hole
In the above, 80g / m ² or more of the upper drug containing resin component
Offset printing containing thermoplastic resin component on coated paper
Paper that has been printed with ink for
Hot pressing the same part to remove the resin component contained in the medicine and ink.
Compatible and heat welded to each other and separated from the binding
Punching the entire bead into a specific planar shape
A calendar is provided.

[0005]

[Action] By taking the above measures, the present invention firstly
Since the paper is bound only by heat welding, no metal fitting is required. In this case, the role of the adhesive at this time is the ink component printed on the paper surface and the resin component contained in the medicine applied to the paper surface, which is heated and melted to bond each paper surface. In the following, since the entire body are die cut to specific shapes, giving novelty in design, increasing the added value.

[0006]

FIG. 1 is a plan view of a calendar A showing an embodiment of the present invention. In this embodiment, the whole is cut into the shape of a bunch of grapes, and from January to December. Twelve sheets of paper 10 on which the date and day of the week are printed are stacked, the upper part of which is superimposed and bonded to form a binding part 12, and the lower part is a separating part 14. In the present invention, the binding portion 12 is bound only by heat welding without using an adhesive or the like. FIG. 2 is an explanatory view showing this heat welding state.
Paper 10 that has been stacked (at this time, the die has not yet been cut)
Is intermittently moved by the conveyor 16 or the like, and the table 18 is set below at the bonding station.
It is held down. At this time, a hooking hole 22 and the like are also formed at an appropriate position of the binding portion 10.

By the way, the ink for offset printing contains a thermoplastic resin component such as Colorama (trade name), and is used as a binder for fibers added to paper and applied to the surface of paper. Because the medicine also contains a resin, when heat and pressure are applied to these, the resin such as the medicine on the paper melts, dissolves with the resin component contained in the ink, penetrates into the paper and is adjacent The fibers of the paper are joined together and integrated as if they were a piece of cardboard. In this sense, it is a condition that the paper surface 10 is subjected to offset printing, and it is preferable that the medicine applied to the paper surface 10 be used in an amount of 80 g / m ² or more. Furthermore, the conditions for thermal bonding are as follows:
0 to about 100 ° C and 100 to 150 kg / cm
It is sufficient to squeeze in the pressure of ² for 1 to 3 seconds.

Next, a perforation 24 is formed at the boundary between the binding section 10 and the separating section 12. FIG. 3 is an explanatory view showing this. In the perforation forming station, the needle 26
Is mounted on the paper 10 and the perforations 24 are made on the paper surface 10 (the conveyor 16 leaves this part). At this time, a table 30 having a hole through which the needle 26 can be inserted is set below, and the head 28 and the paper 10
In the present invention, the interval between the needles 26 is reduced, and the pitch of the perforations 24 is reduced.

In order to make this possible, it is necessary to make the pitch of the holes formed in the base 30 and the holding plate 32 fine, but it is important to divide them appropriately. Specifically, it is preferable that the relationship between the diameter D of the perforation 24 (needle 26) and the pitch P is about P ≒ 1.5D (conventionally P ≒ 2D). This facilitates peeling. The perforation may be performed in a step before the heat welding.

Finally, the paper 10 subjected to the above processing is die-cut into a required shape. This die cutting is generally carried out by a method called Thomson processing in which the blade is pressed by a blade formed into a whole shape. Thomson processing is a paper surface with a head with a blade attached
Since it is possible to push the zero, it becomes possible only by not using the metal fittings as described above. It should be noted that various shapes can be considered as the shape of the cutout.

By the way, the above is the description of the calendar, but the present invention is not limited to this, and the present invention can be similarly applied to, for example, a schedule table, a memo, etc. for peeling a used one. Of course.

[0012]

As described above, according to the present invention, the paper is bound (bonded) only by heat welding without using a metal fitting or the like and without using an adhesive. Not necessary and resource saving. Also, production cost is low
No. In further, if the form unplug the whole into a particular shape, design is made to the novel, there is an evocative effect the demand.
