This chapter includes blades used for perforating paper, foil, etc. They are used for perforating block calendars, printed forms, cement bags, toilet paper and boxes for tissues.
These tools can have different tooth shapes (by request of the customer), lengths, design, hardness and steel used. We offer perforating bands from a thickness of 0.2 mm, which are used e. g. in bagging machines - these are supplied as a band - or even thicker, supplied in pieces.

Perforating knives may cut both against the plate, metal roller and against each other when one of them is toothed and the other smooth, and/or into a free space (slot).
The perforating blades can even be circular - we offer these products. They can be ground or cut and as you can see in Figs. 3 and 4, ground teeth can have another angle. These teeth can enter the material in a better way and their cutting edge is more stable.
