Why the tool should be placed angled in the cylinder die cutter?

Flatbed die cutting machines cutting the whole sheet at the same time. It needs a big force so flatbed die cutters are big, robust and certainly expensive devices. Cylinder die cutters are different: The cylinder rolls through the sheet cutting the whole width in the same time but in longitudinal direction cuts only a small length at once.

If the die cutting tool has long straight cutting lines ant they are positioned parallel to the cylinder then the cutting force increasing very much when the cylinder rolls upon this lines.

Do to the increased force the cylinder curving so the device can't cut the whole width in the same way.
You can reduce this effect by placing the steel rule die cutting tool angled under the die cutting cylinder.
