Mechanical and pneumatic paper punches

We have created similar paper punches with mechanical and pneumatic operation. 

Mechanical paper punch

Pneumatic paper punch

There are different custom punching tool sets are available. The punching tools made of hardened tool steel with Electrical discharge machining (EDM)

You can put even more sets of tools into the device.

Paperfox MP-5 die cutter prototype

Here is our new prototype:

If someone needed a bigger press, we could only solve the problem so far by modifying the machines already in production.

With the new press, you can punch up to A6-sized punches. 

We do not yet know what accessories and prices we will make for this press, and we will thank you for your suggestions.

Coreless rewinder prototype

You don't need to use paper cores to rewind paper, plastic foil, corrugated paper or other similar roll materials, because we've developed the Paperfox CLR-5 coreless rewinder. 

Thanks to a completely new operating principle, the machine is smaller, lighter and cheaper than any other similar device.

The Paperfox CLR-5 coreless rewinder can rewind roll materials up to 70cm width. The length to rewind and some other parameters can be set with a programmable controller.

How is it made?

First we tried to solve the problem in a traditional way. The machine was big, heavy and it had a lot of expensive components. In addition it don't worked well with all kind of paper.

Then we find out a completly new solution to this task. In the following video you can see our first trial to test the new principle:

The test was successful, so we created the first working prototype:

Then we reduced the size and applied a programmable controller to adjust the desired length to rewind and some other parameters.

The construction is still subject to change, we are open to any suggestions.

I hope it'll be a very successful product in the future.

Paper punch with push through tools

Paperfox manufactures different paper punches with steel rule dies.
Steel rule dies are versatile, easy to manufacture devices, but but they are not always suitable for larger, heavier jobs.
So we have manufactured a pneumatic paper punches with push through tools.

The device has a circle, oval and euro slot shaped punch tools.

Medical blister punch

We've already made blister cutters, but now it's a bit different.
This machine is based on the well-proven Paperfox EVV-3 Cardboard edge protector cutter, which is equipped with a special blister holder and adjustable positioning elements.

Solutions to align cylinder die cutters to the printed printed pattern.

1. Sticking cardboard strips on a foam material to align the sheet to.

Stick some foam material onto the die cutting tool and stick cardboard strips with double sided self adhesive tape on the foam. You can position the sheets which you want to die cut to this cardboard strips. Perhaps this is the easiest solution but the accuracy is sometimes not enough. Unfortunately the foam allows not only up/down movement the positioning cardboard strips can move during the process sideways.

There is a video about this process: https://youtu.be/kb2NERpQv7A

2. Alignment with positioning pins

The problems with the accuracy of the positioning with cartons trips sticked on foam material can be eliminated with using positioning pins as in the following pictures.




Thie die cutting cylinder can push down the collapsable pins and a spring pushes them back.

There are 8 positioning pins at the corners of the sheets to be die cutted.

There is a video about this process: https://youtu.be/cioDSYwkv8g

3. Positioning with steel rules

A very similar solution is to position the sheet with a spring steel rules as in the following picture:

The steel rules can be fixed on the die board with screws. The sheets can be positioned to this steel rules.

There is a video about this process: http://www.youtube.com/watch?v=YJWUcrQM9v0

4. Alignment with a transparent plastic and hinge

Mount a piece of transparent plastic with a hinge on the die board. Place positioning marks on the plexy. In this tool we pressed the the plexy against the cutting edges so that the trail of the cutting lines should appear on the plexy. We have strengthened this traces with a marker pen. (blue lines in the picture) Place a sheet on the tool, fold the plexy above the tool and align the sheet to the marks on the plexy. Fold the plexy away, place a cutting plate on the sheet and now you can die cut with your cylinder die cutter.

5. Fold up table

Mount a fold up plate with hinges on the table of the die cutter and fix the tool onto this plate. Stick cardboard strips on the cutting plate to position the sheets. In this way you can place also creasing matrix on the table to improve the quality of creasing.
Unfortunately this solution needs more cutting pressure and you can't cut big, complicated shapes or hard materials in this way.

There is a video about this process: https://youtu.be/mR3yxG2zZus

6. Transparent tool

We can manufacture transparent die cutting tools so you can position it easily to the printed pattern. This solution is optimal if the sheet is big and the die cutting tool is small. 

There is a video about a similar process with a flat bed press:

7. Positioning with laser

We have manufactured a devices with you can position the sheets which you want to die cut to a laser “+” mark.

How to punch in the middle of sheets with a Paperfox KB 32 paper punch?

Paperfox KB-32 is a really versatile device, which is originally equipped with a euro slot punch tool.
You can replace this tool with another die cutting tool and you can punch even special holes. If you replace the creasing tool with a die cutting tool then you can punch in the middle of bigger sheets as well.
