1. If the drum pressure of the rotary die cut machine has been adjusted appropriately, the circumferential direction of the problem does not go, if the paper conditions are very good will not burst the line, you can remove the die-cut knife plate, with a screwdriver will be pressed from the inside to the outside of the line knocked out some.

And then to the inside of the die-cutting board pressure line position pad on a thin wire, and then the die-cutting board is installed, this time the die-cutting pressure line than before higher than the distance of a wire, the effect of pressure line will be more obvious.

If the pad over the wire after the explosion of the line, the pressure line after the high pad pressure line edge strips can not play the role of the original to prevent the explosion of the line. At this point you can remove the die-cutting board to take out the wire, the pressure line smashed back to the location of the wire is not installed, in the pressure line corresponding to the position of the paste on a 0.71mm die-cutting pressure line or iron.

The principle is to press the wire and press the wire edge strip together with the pad, generally can solve the problem.

In the actual handling of the problem when the thickness of the wire and the thinness of the iron needs to be processed according to the material and thickness of the cardboard to try again and again, subject to the best results.

2. In the processing of cardboard backing paper is thin and tile paper is hard, if the backing paper burst line and pressure line does not go line of the problem and how to deal with it?

To solve this problem the key in the pressure line on the treatment of the sidebar, neither the pressure line can not let the sidebar is too low and can not let the sidebar is too hard, too low will cause the burst line, too hard to make the pressure line is not obvious, do not go line.

First of all, we must choose a wide pressure line side strip, in the choice of a plastic packing tape, plastic packing tape nailed to the lower side of the rubber side strip, packing tape to leave the pressure line position 3-4mm, and rubber side strip in the pad on the packing tape should be higher than the pressure line. To put out of the rubber edge with a wood file filed to the pressure line and flat, the arc of the edge of the strip is not too large, so that the edge of the strip made neither burst line and will not not go line.
