Abstract

PROBLEM TO BE SOLVED: To make a correct folding when folding a stepped line of a corrugated paper along a rule coinciding with the stepped line by forming adjacent parts to a main line extended in the stepped line direction of a corrugated paper by crushing the adjacent parts into forms which are discontinuous in a parallel direction to the main line part, starting with a face directed inwardly when folded. SOLUTION: The folding rules 21, 22 of a box material are composed of a main line part 27 and adjacent parts 28 respectively. The main line part 27 is extended linearly in the stepped line 29 direction of a corrugated paper and is crushed starting with a face which is directed inwardly when foled. The adjacent parts 28 are formed in short straight lines, crossing the main line part 27 and arranged ade by side along the main line part 27, by crushing the short straight lines starting with the face to be directed inwardly when folded. If the main line part 27 is foled along the folding rules 21, 22, the main line part 27 can be normally folded as a folding line, when the folding is started. However, if the folding is further carried out, and the inner cores of the corrugated paper are crushed by their mutual collision, the inner cores are discontinuously crushed in a direction along the main line part, 9 the adjacent parts, in the folding rules. Consequently, the average strength of the inner cores is deteriorated, so that the inner cores can be easily crushed.

First, a box material 1 shown in FIG. 1 is formed from corrugated cardboard. That is, punching into the shape of FIG.
Ruled lines 2, 3, 4, 5, 6, 7 are formed. These ruled lines are linearly crushed from the inner surface when bent. While the box material 1 is transferred from the top to the bottom in the figure, it is bent along the ruled lines 5 and 7 by using a twisting belt or the like, and the margin 8 is adhered to manufacture the box 9 shown in FIG. Note that, usually, in a box maker, the state shown in FIG. 2 is regarded as a completed box product and is sold in this state.

When the box 9 is normally formed, it is in the state of FIG. 2, but the box 9a of FIG. 3, the box 9b of FIG. 4, and the box 9 of FIG.
In many cases, defective products such as c are generated. The box 9a has a shape in which the rear part is widened during transfer, and is called a fishtail phenomenon. The boxes 9b and 9c have widths 10b and 10c which are to be formed in the size 8 portion.
However, it is either too large or too small to be normal.

In this box material 1 and box 9, the corrugated paper corrugations are arranged in the vertical direction as shown in FIG. The ruled lines 5 and 7 are folding ruled lines that can be bent in this manufacturing process, and the direction thereof matches the step of the corrugated paper. If you fold along a ruled line that matches the corrugated line of corrugated paper, the fold line is unstable and can not be folded normally,
The above defective products are likely to occur.

The reason for this is considered as follows. That is, when the formed ruled line is bent, as shown in FIG. 6, the inner core 12 of the corrugated paper 11 is crushed in a portion adjacent to the inner ruled line, but many irregularities of this center line are present. In this case, since there is no symmetry with respect to the ruled line, the crushing tendency becomes asymmetrical, which causes the actually formed fold line to move from the position of the ruled line.

For this reason, the folding lines of the ruled lines 5 and 7 are shifted,
Boxes 9b and 9c are generated. In addition, since the bending is performed by a twisting belt or the like, the bending is gradually performed from the front at the time of bending, so that the folding lines gradually shift and become slanted, and the box 9a is generated.

In the box material 20 shown in FIG. 7, the folding ruled lines 21 and 22 are both constructed as shown in FIGS. 8 to 10, and the other ruled lines 23, 24, 25 and 26 are in the same linear shape as the conventional one. It is squeezed from the inner surface when folded. Each of the folding ruled lines 21 and 22 includes a main line portion 27 and an adjacent portion 28. The main line portion 27 extends linearly in the direction of the step 29 of the corrugated cardboard and is crushed from the inner surface when folded. The adjacent portion 28 is the main line portion 2
A number of short straight lines intersecting 7 are arranged along the main line portion 27 so as to be crushed from a surface which is an inner side at the time of bending.

Since the folding ruled lines 21 and 22 are configured as described above, they act as follows. When it is bent along this folding ruled line, initially, like the conventional ruled line, it is normally bent with the main line portion 27 as a folding line.
Further bending, as shown in FIG. 6, when the cores of the corrugated paperboard collide with each other and are crushed, in this folding ruled line, the cores are intermittently crushed by the adjacent portions 28 in the direction along the main line portion. Therefore, the average strength of the core is reduced and the core is easily crushed. Therefore, it is possible to prevent the fold lines from being displaced, and the fold line is bent at an accurate position.

Further, with respect to the fish tail phenomenon shown in FIG. 3, in addition to the above-mentioned action, the following action also works. That is, when the folding ruled lines 21 and 22 are gradually bent from the front, the stress concentrates on the intersection of the short straight lines of the main line portion 27 and the adjacent portion 28, so that the bending progresses sequentially from this intersection, and as a result, along the main line. Fold lines are formed. Therefore, the fish tail phenomenon is also reliably prevented.

As is clear from the above operation, the adjacent portion is
The shape may be any shape as long as it is adjacent to the main line portion and is interrupted in the direction along the main line portion. Therefore, it can be arbitrarily selected in addition to the shape in which a large number of short straight lines intersecting the main line portion are arranged. In addition, the width of adjacent portions (the length in the left-right direction in FIG. 8), the interval (the interval between the short straight lines in FIG. 8), the existence ratio (the ratio of the width of the short straight line to the short straight line interval in FIG. 8), the crushing The depth (thickness reduction amount in FIG. 10) can be variously set.
