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.

Why not exactly 90 degrees is the angle of the corner rounding knives?

Paperfox S-3 corner rounder

Corner rounding is a very sensitive operation, because even the smallest inaccuracy causes a visible error.

Ideally the corners could be rounded with a 90 degrees knife, or we could round the corners even with a simple quarter-circle profile.

Unfortunately, in practice, this profile does not result in the best rounding because:

  • The corners of the sheets to be rounded are not exactly right-angled, and the angles of the corners are not exactly the same.
  • The adjustment of the guides of the corner rounders are not perfect, so the rounding does not fit exactly to the corner of the sheets. 


The drawing below shows how the corner is rounded when its opening angle is equal to smaller or greater than the angle of the corner rounding knife.




The first column shows how a perfectly right-angled knife would behave when rounding a perfectly right-angled corner with perfectly accurate adjustment. (Perfectly)

The second column shows a knife with an opening angle (95 degrees) slightly larger than the corner angle of the paper. Although the result is not perfect, but even with some misalignment, the error is not significant.

In the third and fourth columns there is a knife with an opening angle (85 degrees) slightly smaller than the corner of the paper. The knife in this case not cuts the corner completely or the blade edge will cut into the paper. Even the slightest inaccuracy results a visible error.

Therefore, it is advisable to choose the opening angle of the rounding blades slightly higher than 90 degrees.

The situation is similar with the side guides in the corner rounders. If the angle of the guides is slightly larger than the corner angle of the paper, it will result in a much less visible error than if it would be smaller.

Slitting device

With this simple device you can create special tabs on the self adhesive product to help the removal of the protective silicone paper.


Paper core cutter

We have manufactured a paper tube cutter. To reduce the costs we have used our cheap A-1000 rewinder as a base and we've put a cutting head on it.


First we've equipped the device with a rotating kinfe.


Then we've realised that in most case the simple straight blade is not only cheaper but also better.


If the paper core is too strong to cut with a simple sewing machine motor we can mount this head on the stronger AH-1000 rewinder.

Paperfox FSD-1 taper applicator prototype with a stepper motor

The Paperfox FTD-1 tape applicator with conveyor belt is a successful product, but it needs compressed air. Now we created a tape applicator head with an electric stepper motor so the tape applicator can be used without compressed air.

Unfortunatelly the stepper motor is bigger than a pneumatic cylinder so this new tape application head needs more space than the pneumatic version.
