During the cut, the tangential knife velocity must match the linear speed of the material.
During the rest of the revolution, the knife must either speed up or slow down to be ready for the next cut.
Most rotary knife applications are continuous operation with material continuously moving along the conveyor belt.
The knife axis (slave) is geared electronically to the feed axis (master) so that the material cut lengths are independent of the material feed speed.
This application note discusses two types of rotary knife application, Simple and Registration.
In the Simple application, the material length is fixed in the programme or selected by an operator and the cuts are made continuously.
The Registration application adds a Registration Mark Sensor (RMS) that detects a registration mark on the material where the cut is to be made.
The material length is variable and the RMS may be several material lengths from the knife.
