As we all know, the wheel offset press is composed of three parts: paper feeding, printing and folding. Among them, the folding machine can be rolled according to the folding method and impact folding.
The following is an analysis of the fault phenomena and their causes in the folding process of the general rotary glue bream machine and the corresponding treatment methods.
1. When the paper tape is folded vertically, the two are uneven or run unevenly on the triangle board
the reason:
1. The axial direction of the roll paper is not correctly positioned;
2. The pressure of the paper pressure roller on the paper belt drive roller is uneven;
3. The setting of the release roller is too loose;
4. The triangular plate and the belt drive roller are equal and skewed.
deal with:
1. Correctly set the axial position of the roll paper;
2. Adjust the pressure of each pressure roller to make it uniform;
3. Reset the folding roller gap;
4. Adjust the triangular plate to be parallel to the paper belt drive roller.
Note: After the printing press is installed, the folding triangle has been set and rarely needs to be adjusted, so before readjusting the triangle, be sure to check and queue other possible faults.
2. Wrinkles appear at the vertical folding creases or wrinkles along the vertical folding direction
the reason:
1. The folding roller setting is too loose;
2. Excessive paper feeding (the reason may be caused by the sticky rubber roller caused by excessive ink or other related factors);
3. The angle of the folding triangle is too large;
4. The triangular plate and the paper belt drive roller are not parallel or skewed.
deal with:
1. Reset the folding roller gap;
2. Reduce the ink supply and scrub the rubber roller;
3. Reset the angle of the folding triangle plate;
4. Adjust the triangular plate to be parallel to the paper belt drive roller.

3. A crack or crack appears at the tip of the triangular plate
the reason:
1. The paper guide roller and folding roller are too tight;
2. The angle of folding triangle is too small.
deal with:
1. Reset the gap between the paper guide roller and folding roller;
2. Reset the angle of the folding triangle.
Fourth, the longitudinal edge of the paper is fluffed or the longitudinal slit is not smooth and there is a tear
the reason:
1. Longitudinal cutting of paper hate piece (at round knife) is passivated or broken;
2. The round blade is not correctly set in the notch of the driving roller.
deal with:
1. Replace the slitting paper blade (ie round blade);
2. Reset the position of the circular blade in the slot of the drive roller.
5. The cross-cutting position is incorrect, and the position of the header is unsatisfactory or half-finished
the reason:
1. The adjustment position of the adjustment roller (paper roll) is incorrect;
2. There is an error in the paper route.
deal with:
1. Adjust the roller, and change the folding position of the root head;
2. Change the paper route.
6. Excessive tearing of the needle-the pinhole of the book sticker is broken
the reason:
1. The gripper on the roller is dull, bent or broken;
2. The cam setting of the gripper is not correct;
3. The folding roller setting is too loose;
4. The cam for controlling the movable gripper is set incorrectly;
5. The set of gripper corresponding to the knife is not set correctly.
deal with:
1. Repair or replace the gripper on the drum;
2. Reset the position of the cam that controls the gripper;
3. Reset the folding roller gap;
4. Reset the cam position of movable gripper;
5. Reset the relative position of the folding knife and gripper.

7. The horizontal cutting edge of the paper is uneven, fluffing or tearing
the reason:
1. Wear of cutting rubber strip;
2. The cutting blade is blunt or cracked;
3. The lack of elasticity of the blade rod pad spring leads to inflexible movement
4. The spring of the blade rod pad gasket is damaged and the pad cannot be reset.
deal with:
1. Replace the cutting rubber strip;
2. Replace the cutting blade;
3. Replace the blade rod pad spring;
4. Pad or replace the blade rod half pad spring.
8. Continuous cutting of paper
the reason:
1. The cutting knife is too low;
2. Wear of cutting knife pad or rubber pad;
3. The cutting blade is worn or not sharp;
4. The spring of the blade pad under the cutter holder is not elastic enough, and the recovery is weak, which causes the cutter to cut the paper tape not under the tension of the paper tape.
deal with:
1. Heighten the cutting blade;
2. Replace the cutting knife liner or cutting rubber strip;
3. Replace the cutting blade;
4. Replace the blade pad spring.
Nine, eight or thirty-two double folding fold crease skew
the reason:
1. The folding knife edge of the one-fold roller is not parallel to the center line of the roller;
2. The folding knife edge of the two-fold roller is horizontal to the center line of the roller;
3. The clamping force of the folding clamp to the folding width is inconsistent.
deal with:
1. Adjust the folding knife edge position of the one-fold roller so that it is parallel to the center line of the roller;
2. Adjust the position of the folding blade of the two-fold roller so that it is equal to the center line of the roller;
3. Adjust the clamping plate to make the clamping force consistent.
Ten, eight or thirty-two double folding folds are not in the middle
Cause: The position of the eight-fold or thirty-two-fold folding knife is incorrect.
Treatment: adjust the position of the eight-fold or thirty-two-fold folding knife in the drum groove.
Eleven, eight or thirty-two double-folded paper
the reason:
1. The position of the folding knife and the splint is incorrect;
2. Folding knife and splint are not parallel;
3. The folding knife is too low.
deal with:
1. Adjust the relative position of the folding knife and the splint;
2. Adjust the folding knife and the splint to make them parallel;
3. Raise the folding knife.
The twelfth and sixteenth folds are not in the middle
Reason: The 16-fold folding knife is not in the middle of the 8-fold folding post.
Remedy: Adjust the sixteen open frame or sixteen open folding knife frame to the correct position.
Thirteen, sixteen open fold creases crooked
the reason:
1. The uneven pressure of the page brush is uneven;
2. Poor positioning of the 16-fold folding conveyor belt and uneven pressure;
3. The sixteen-fold hinge stopper is not perpendicular to the folding knife.
deal with:
1. Adjust the pressure of the folding brush to make the pressure even;
2. Adjust the conveyor belt to ensure uniform tension and uniform pressure;
3. Height adjust the stopper to prevent the paper plane from being perpendicular to the folding knife.
Fourteen and sixteen folds are not true
the reason:
1. Poor setting of the 16-fold folding roller inlay position;
2. The pressure of the 16-fold folding roller is not enough.
deal with:
1. Change the relationship between the folding roller and the 16-fold folding knife so that the 16-fold folding back is just at the position of the mounting strip;
2. Adjust the spring or air cylinder to make the folding roller have enough pressure.
Of course, specific analysis and processing are required for different folding machines, and the above analysis can only be used as a reference.
