[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when punching a blank, which is a board for assembling a paper container, from a raw sheet in a paper punching operation, or at the same time, stamping a paper product made of paperboard or corrugated board. In this case, the present invention relates to a groove forming material for ruled lines, which can surely and easily form grooves for forming ruled lines on the surface of a mold board.

[0002]

2. Description of the Related Art Among paper products, a blank, which is a plate material for assembling a paper container, is cut into a predetermined shape size or a cut by a punching-type cutting blade, and as a bent portion or a folded portion.
A ruled line that forms a fold is created by the ruled line pressing blade, and smooth folding or folding is performed along the ruled line. In order to stamp accurate and useful ruled lines on the blank, a groove with a width determined by the thickness of the ruled blade and the blank material thickness is provided at the key point of the die-making mold surface that forms the blank. However, it has been attempted to impress the required crease lines on the blank with these grooves and the scoring blade that is driven to an appropriate depth in the groves. There is no need to engrave them on the surface of the mold board, and a thin cardboard or the like is adhered to the two parallel ridges on the surface of the mold board so that the gap between these two ridges is substantially removed. Means used as a groove are widely adopted, and various kinds are disclosed so as to be suitable for the purpose.

The inventor of the present invention firstly fixed a ribbon-shaped adhesive substrate on the ruled groove and, while being bonded to the ruled blade, hits the ruled groove on the mold surface to form a ruled groove accurately aligned with the ruled blade. Japanese Patent Application No. 57-131225 (Act No. 59-35025) for a grooved tape device for ruled lines that can be formed on top.
As proposed.

[0004]

According to the present invention, it is possible to form a scoring groove immediately below the scoring blade very easily and the productivity is improved. However, the combination of the groove tape and the scoring blade is ribbon-shaped. Since it is configured with an adhesive substrate, it may be difficult to maintain an accurate right angle between the two, and it is necessary to have a local inspection in order for the adhesive layer of the groove tape to contact the mold surface all at once on the left and right sides. At the same time, it was difficult for the ruled line pressing to reach the groove tape edge region.

In view of such a situation, the present invention provides a groove having a width adapted to the thickness of a blank sheet material when a groove necessary for forming a ruled line on a blank or the like is formed on a mold plate surface by a ruled blade. It is an object of the present invention to provide a means for accurately providing the above on the surface of the mold board while aligning with the pressing line of a predetermined ruled line pressing blade.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a ruled groove is formed by two groove forming portions which are arranged facing each other with a constant space, and a release paper is provided on the back surface side of these groove forming portions. A pressure-sensitive adhesive layer coated with is provided, and on the scoring grooves, there are flange edges on both sides of the groove forming portions on both sides, and a set groove for the scoring blades that matches the center line of the scoring grooves is provided. A strip is provided, and each attachment tape is attached to the upper surface along the length direction across the both so as to keep the fixing auxiliary strip and each groove forming portion in a fixed state. Each of the joining tapes is a groove forming material for ruled lines, characterized in that one side thereof can be bent and inserted into the set groove of the attachment auxiliary strip.

[0007]

According to the crease forming groove forming material of the present invention having the above-described structure, the attachment auxiliary strip for setting is provided in the crease forming groove formed by the two groove forming portions. Since the flange edges formed at both ends are provided so as to hang over both groove forming parts, the bonding tapes are adhered in the length direction across the upper surfaces of the mounting auxiliary strip and each groove forming part. The attachment auxiliary strip is held in a stable state with respect to the ruled groove portion without being separated from both groove forming portions. Therefore, if the set groove of the attachment auxiliary strip that is provided on the center line of the scoring groove is fitted to the tip of the scoring blade, then the scoring is performed with the release paper on the back side removed. By simply striking the blade onto the surface of the mold board, the groove forming material for scoring is adhered to the surface of the molding board, and then it is separated from the groove forming material for scoring with the scoring blade and stamped on the surface of the molding board. The groove is formed in alignment with the ruled line. Moreover, since one side of each joining tape that has been pasted on the upper surface of the attachment auxiliary strip can be bent and inserted into the set groove,
When the ruled blade is inserted into this set groove, the folded part of the joining tape enhances the contact with the tip side of the ruled blade,
It is possible to enhance the effect of setting the groove forming material for ruled line pressing on the ruled line pressing blade.

[0008]

According to the present invention, the mounting auxiliary strip and the two strips for forming the scoring grooves are set in handling before setting the scoring material for forming the scoring on the scoring blade and driving it on the surface of the mold board. The groove forming portion is kept in a state where it is not loosened by the joining tape, and the attachment auxiliary strip is held in a stable state with respect to the scoring groove and can be handled integrally. In addition, since one side of the joining tape can be bent and inserted into the set groove of the attachment auxiliary strip, when the ruled blade is inserted, the joining tape is folded and locked to the side of the ruled blade. The force has been increased, the stability of the mounting of the groove forming material for the ruled blade on the ruled blade has been improved, and it has become possible to perform the groove forming operation accurately with a simple configuration.
