12.1.9 Operation
This section explains an operation using the simple cam function with concrete examples.
(1) Example of a rotary knife device
(a) Configuration example
The rotary knife cuts the sheet conveyed by the conveyor at a constant speed into a desired length.
To prevent variations in the sheet length and a cutting position mismatch, this device reads
registration marks that have been printed on the sheet, and compensates cutting positions.
