Question 7: The label has not yet been cut off but it has broken (see Figure 6).
The reason for this problem is:
1, this die cutter does not apply to the label base paper;
2. If the problem only occurs in the direction of rotation, there is a problem with the fixing of the die-cutting device;
3, the bottom paper is too thin and too soft, and the label base paper is too hard and too tough.

How to properly use the magnetic cylinder and the flexible die cut a) The magnetic cylinder 1 is cleaned before each use;
2. The most care should be taken to protect the gear during the move;
3. Apply anti-etching protective grease during storage.
b) Anvil drum 1, clean before use;
2, always check the circumference change caused by the roll
3、Check once when adding an anvil cylinder;
4, Roller should be cleaned and refueled frequently.
C) should be careful to use flexible die-cut 1, always check;
2, can not easily bend;
3, can not be placed on a die cutter;
4, before installing on the magnetic roller should first clean the back.
d) Storage of flexible die-cuts 1. Small movements after use;
2, can not be placed on a die cutter;
3, should be clean at the end;
4, internal and external anti-corrosion protection grease should be applied;
5, wrapped with oil paper, placed in a carton.
e) Precautions for printing 1. Ensure that the pressure between the magnetic roller and the anvil roller is appropriate;
2, the pressure treatment cylinder shaft installed in the appropriate position of the roll;
3, determine the machine plus no gaps;
4, pay attention to the cleaning of the roll and pressure roller shaft oil.
f) Check 1, check clearance every 6 months;
2. Every time changing the printed product, the flexible die-cutting plate should be replaced;
3, try to avoid different gaps or replace the anvil drum;
4, always check the roll, frame and pressure roller.
A few suggestions to the manufacturer Correct manufacturing can avoid many problems. Before leaving the factory, manufacturers should pay attention to the following details:
1. A few proof sheets of paper must be tested;
2. If multiple composite materials, should pay attention to which knife cut which layer;
3, if it is on-line production should pay attention to the compound before the die-cut, or compound die-cut;
4, the bottom paper is discharged from the label, or another winding;
5, commonly used gap size;
6, flat pressure or rotary die cutting;
7. The circumferential size of magnetic drum is in inches or millimeters;
8, the type of machine used, the width of the die-cut version;
9, special die-cut shape should be marked in advance;
10. Die cutters should be perforated by millimeters.
