させるという問題もあった。However, in a conventional slit forming device in which the corrugated paper is advanced while being held between a rotary cutter and a feed roller as the device for forming the slit 2, there is a gap between the corrugated paper and the feed roller. Frictional resistance causes a discrepancy with the cutting speed of the cutter, resulting in problems such as insufficient slit formation or cutting not only one surface but both sides of the cardboard. Furthermore, setting the conditions until optimal cutting is achieved is a process of trial and error, which takes a long time, and having to set the settings each time the type of corrugated paper changes significantly reduces production efficiency. there were.

フの位置を自在に調節するものである。Further, in front of the above-mentioned feed roller 5, a cutter 7 is arranged on the slit-forming surface side 6 of the single-corrugated cardboard 3 so as to be in contact with the front paper of the corrugated cardboard. The cutter 7 is held at a fixed angle by a fixed plate 9 fixed to a bracket 8, and a sprocket 10 is connected to a sprocket 12 connected to a drive shaft 11 via an endless chain 13, and rotates at a predetermined speed. It is something that will be done. The bracket 8 is connected to the machine base 4 by the main shaft 14.
It is fixed to the cutter, and can be adjusted to any position using a vertical adjustment @ 15 made of screws, etc., thereby freely adjusting the position of the cutter according to the thickness of the corrugated paperboard 3. It is.

している。On the other hand, as shown in FIG. 3, on the general surface side 16 of the corrugated paperboard 3 located on the opposite side of the cutter 7, a free roller 17 is arranged corresponding to the cutter. The free roller 17 is rotatable with respect to the shaft 18 through, for example, a bearing, and does not generate frictional resistance between it and the corrugated paperboard 3 in contact with it. Behind where the cutter 7 and free roller 17 are arranged in this way, there is a pair of upper and lower delivery rollers 18 that sandwich the corrugated paperboard 3 and send it out of the machine base 4, and when the slit formation is completed. The corrugated paperboards 3 are sequentially carried out at a predetermined speed.

る。In the drawings of the embodiment, a plurality of cutters 7 and free rollers 17 are arranged on the extension line of the same main shaft 14 and drive shaft 11, and the slit forming surface side 6 and the corrugated paperboard 3 are arranged in plural numbers. General surface side 1
A cutter 7 and a free roller 17 of the same mechanism are arranged so that the cutter 7 and the free roller 17 are upside down and the slits on the upper and lower surfaces are alternate.
and arranged at equal intervals. The cutters 7 and the free rollers 17 can be freely arranged in any number or at any interval depending on the desired form of the corrugated paper on which slits are to be formed. .

進することとなる。In the apparatus for forming slits on the surface of corrugated paperboard constructed in this way, when the corrugated paperboard 3 fed into the machine stand 4 advances at a predetermined speed by the feed roller 5, the cutter 7 disposed in front cuts the corrugated paperboard 3. The slit 2 is cut by contacting the slit forming surface 6 and by its rotational force.
The corrugated paperboard 3 is advanced while forming. On the other hand, the free roller 17 disposed on the opposite side of the cutter holds the corrugated paper 3 so that the cutting force of the cutter is sufficiently applied to the slit forming surface side 6, or holds the corrugated paper 3 in a freely rotatable state.
Since the structure does not generate any frictional resistance between the corrugated paperboard 3 and the cutter, the corrugated paperboard 3 moves forward while reliably forming the slits 2 only on the slit forming surface side 6 in accordance with the cutting speed of the cutter.

As shown in FIG. 4, corrugated paperboard 3 is obtained in which slits 2 are alternately formed at equal intervals on both the upper and lower surfaces. This corrugated paperboard 3 with slits is then further cut, for example, along the line shown by the - dotted chain line, and predetermined portions are pasted to complete the honeycomb-shaped corrugated cardboard core material 1 as shown in FIG. Become.
