Detailed Description of the Invention

[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. And, in order to stamp accurate ruled lines on the blank, at the key points of the die surface of the punching die that forms the blank,
A groove having a width determined by the thickness of the ruled blade and the material thickness of the blank is provided, and the required ruled line is stamped on the blank by these grooves and the ruled blade that is driven to an appropriate depth in the groove. However, at present, it is not necessary to engrave the groove corresponding to this ruled-pressing blade on the surface of the mold board, but to form a narrow cardboard on the surface of the mold board into two parallel ridges. Means for adhering and utilizing these two ridge-shaped gaps as substantial grooves are widely adopted, and various types have been disclosed so as to be suitable for the purpose.

The inventor of the present invention first creates a scoring groove on the surface of the base sheet, fixes the ribbon-shaped adhesive substrate on the groove, and then, while bonded to the scoring blade, hits it on the surface of the mold plate to press the scoring blade. A grooved tape device for grooved lines that enables the formation of a grooved line that exactly matches with the patterning plate surface is applied as a practical application.
It was proposed as No. 131225 (Act No. Sho 59-35025).

[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 a structure that is performed via an adhesive substrate, it may be difficult to maintain an accurate right angle between the two.Therefore, it is necessary to locally inspect the adhesive layer of the groove tape to make simultaneous contact with the mold surface 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 suitable for 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 surface by a ruler blade. An object of the present invention is to provide a groove forming material for ruled lines that can be accurately and easily provided on the surface of a mold board while aligning with the pressing line of a predetermined ruled line pressing blade.

[0006]

According to the present invention, two groove forming members are fixed to a front surface of a base sheet at regular intervals to form ruled grooves, and the back surface of the base sheet is covered with a release paper. A pressure-sensitive adhesive layer is provided, and a set groove on which the ruled line pressing blade can be fitted and fitted on the center line of the ruled line groove is provided on the center line, and a flange which is hooked on the groove forming members facing each other is provided. The groove forming material for ruled lines is characterized in that the auxiliary mounting strips having edges on both sides are closely fitted.

[0007]

The groove forming material for ruled lines according to the present invention having the above-described structure has an auxiliary mounting strip for setting when forming the ruled line grooves by the two groove forming members at a constant interval on the base sheet. By adhering on the base sheet so that the corner portions on the opposite sides of the groove forming member are engaged with the corner portions formed by both side surfaces of the piece and the lower surface of the flange edge provided at both ends. The groove forming members can accurately form the ruled groove corresponding to the width of the attachment auxiliary strip. Moreover, the mounting auxiliary strip assembled on the base sheet together with both groove forming members has the set groove provided on the upper side thereof fitted to the tip of the ruled pressing blade to remove the release paper on the back surface of the base sheet. With the
The groove forming material for creases is adhered to the surface of the mold plate simply by hitting the creases on the surface of the mold plate. If the mounting auxiliary strip is removed after that, the creases will be pressed on the surface of the mold plate. It is formed in line with the line.

[0008]

According to the present invention, as described above, the mounting auxiliary strips for forming the ruled groove forming material on the surface of the mold plate by aligning and fixing the ruled line and the ruled groove are provided with the ruled line. By also functioning as a set reference at the time of assembling the push groove forming member, a rational auxiliary material for paper container processing can be obtained with a simple structure.
