DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to securities such as banknotes and the like, in which a watermarking land for preventing forgery and a prominent portion of printing ink are formed, and in particular, a number of such banknotes are stacked and cut. Regarding cutting method in case.

[0002]

2. Description of the Related Art In a banknote manufacturing line, for example, a large number of unit banknotes are printed in rows and columns to prepare multiple large-sized blocks of large-sized banknotes. Cutting, forming a long and narrow multiple strip block, cutting this strip block into unit banknotes to form a multiple multiple unit block, and forming a multiple large block or multiple narrow strip block in each of these cutting processes. A cutting process for scrutiny is essential. This fine cutting generally means trimming for trimming a multi-size block or a multi-strip block to adjust the dimensions.

[0003] In order to prevent counterfeiting in the above-mentioned banknotes and the like, a special watermark-making land portion or printing ink swelling portion is formed at the extreme portion of the printing surface. Not.

[0004] For example, it is presumed that the above-mentioned watermark-making land portion is extremely agglomerated and formed of pulp fibers when a banknote base paper is formed. In addition, the printing ink swelling portion is often applied to a numerical printing portion or a portrait printing portion, and a special ink is used to make the swelling as remarkable as possible generally by intaglio printing.

Therefore, it is obvious that when these banknotes are multiplexed, the above-mentioned watermarking land portion and printing ink swelling portion are superimposed, and the convexities due to the superposition are formed on the poles on the upper surface of the multiply banknote block. A portion is formed, and the phenomenon of upward climbing and one-sided climbing of multiple security blocks occurs remarkably depending on the positions of the watermarking land portion and the printing ink swelling portion. This phenomenon is unique to banknotes,
Similar phenomena can be seen in securities other than banknotes that require counterfeiting prevention.

Conventionally, as shown in FIG. 1, these multiple security blocks 1 are, similarly to other printing paper multiple blocks, a pressing head 2 having a flat pressing surface and a receiving head having a flat receiving surface. The cutting blade 4 is actuated while holding it between the tables 3 to perform the above-described sorting and fine cutting.

[0007]

Thus, securities such as banknotes are required to have extremely strict dimensions.
In reality, a slight dimensional difference is recognized between individual bills, and this dimensional difference has been regarded as an inevitable phenomenon from the manufacturing process.

As a result of various investigations on this phenomenon, the inventor has found that the factor exists in the cutting process, and that the distant factor exists in the above-mentioned banknotes and the like, a specific land for making a watermark, and a raised portion of the printing ink. .

In other words, when securities such as banknotes are multiplexed, a watermarking land portion and a printing ink swelling portion are superimposed, and a remarkable convex portion is generated on the upper surface of the multiplexed securities block by accumulation thereof. I do.

As shown in FIG. 1, when a multiple security block 1 having such a convex portion 1a is held between a press head 3 having a flat press surface and a receiving table 2, the press head 3 is raised. When the portion 1a is pressed, a slip S in the direction of the arrow in the convex portion occurs between the securities in the upper layer of the block, and this slip S is considered to cause a slight shift. It is also assumed that this deviation occurs when the sheet is cut or fined by the cutting blade 4. The present invention has been conceived based on these recognitions.

[0011]

SUMMARY OF THE INVENTION The present invention relates to a multiple securities block formed by stacking a large number of securities each having a watermarking land portion for preventing forgery and a raised portion of the printing ink on an extreme portion of a printing surface. To be cut.

When the cutting blade is actuated while holding the multiple security blocks between the receiving tray and the holding head to perform cutting, such as sorting or fine cutting, the holding surface of the holding head is placed on the holding surface. A concave portion corresponding to the overlapping portion of the watermark making land portion and the printing ink rising portion and having a shape similar to the convex portion formed in the overlapping portion is reproduced.

When holding multiple security blocks between the receiving table and the presser head, the cutting is performed by receiving the convex portion in the concave portion reproduced on the press surface of the press head.

For example, the pressing head is formed of metal,
The concave portion is directly engraved on the holding head, and when holding multiple security blocks between the holding head and the receiving table, the convex portion which swells on the upper surface of the securities block in the concave portion reproduced on the holding surface of the holding head. The part is received and cut by a cutting blade.

Alternatively, a synthetic resin sheet or a rubber sheet having the above-mentioned concave portion which reproduces the above-mentioned convex portion is adhered to the press surface of the above-mentioned press head, and the above-mentioned convex portion is received in the concave portion of the above-mentioned press sheet, and the above cutting is performed.

[0016] A slight gap is formed between the concave portion formed on the pressing surface and the top portion of the convex portion formed on the upper surface of the securities block, so that interference between the convex portion and the concave portion can be eliminated.
