Paper cutters are known to be tools for ultimate convenience of users. They have eliminated the hassles of arranging huge stacks of paper manually and cutting them in the neatest possible way after wasting tons of raw material. Automatic paper cutters, tabletop cutters and many other variants of this machine have sped up the paper cutting process incredibly.

 

But as with all other machines, paper cutters can face many problems during their operations. As seen from innumerable cases, majority of the paper cutter problems are related to poor-performing blades, lack of proper maintenance for the unit, inexperience of the users and unsafe machine operations and so on. Below are some effective ways to avoid these biggest problems of paper cutters at all levels.

Cutting Edge Angle

The choice of the angle of the cutting edge is a very important part of the cutting work. In other words, a good paper cutter must be equipped with a good paper cutting blade and sharpening process. However, we found in the after-sales service of the paper cutter that many paper cutter users often overlook this point. As a result, the method, method and angle of the cutting blade are often wrong, resulting in increased impact force during cutting. As a result, the safety screw is loosened or even broken, eventually causing mechanical damage.

There is a growing range of materials that need to be cut with a paper cutter, such as beer foil caps, carbonless copy paper, honeycomb paperboard, magnetic cards, photographic film, etc. These materials encounter different practical problems during the cutting process. For example, carbonless copy paper will have a indentation during cutting, and the magnetic card and photographic film may not be fixed in the cutting process, resulting in cutting out scraps. These problems can be solved by adjusting the pressure of the platen and improving the blade and cutting drive system.

 

Proper Maintenance

A machine is bound to stop working if it is used roughly and not taken care of regularly. Experts suggest that regular cleaning of the unit is pivotal for its smooth running. Users need to keep its components lubricated so that the paper cutter can cut the papers effortlessly. Whether you are using tabletop cutters or any other variant, make sure that the installation spot is also spic and span for preventing the environment from affecting the machine’s inner parts.

 

Proper Technique

1. Every paper cutter installation should conform to the latest industry standards.

2. When possible, install an effective cut line clamp system to show where the knife is going to cut without lowering the clamp.

3. Use push-outs or “ream ejects” in the cutting program.

4. Ensure the cutter has a two hand start/two hand hold system with an anti-tie down circuit.

5. Always use a jogging block when placing hands under the clamp to side jog material.

6. Check that the cutter has sufficient back up (redundancy) to ensure safety will be maintained if something goes wrong.

7. Ensure proper installation of safety bolts and/or latches to back up the clutch/brake (or hydraulic ram) and prevent the knife from making an unintended cycle.

Clamp Pressure is the Critical Setting

To obtain maximum productivity on a paper cutter, we try to stack piles as high as possible. With the stacking of material, setting the clamp pressure becomes critical. The basic rule of thumb is to use higher clamping pressure for soft material and lighter pressure for hard material.

 

The clamp pressure selected should not be higher than necessary to avoid dislocation or dragging of sheets.

 

Lists of recommended pressure settings for different material are available from a number of paper cutter manufactures. These guidelines for clamp pressure settings, along with proper knife angle, become critical with working with different materials.

 

Conclusion

Problems in paper cutting can be caused by a number of factors, including the material and the paper cutting machines themselves. They can be costly but if the right steps are taken, can also largely be avoided.
