Motion Control Solutions - Rotary Knife

Back to index

A rotary knife is used to cut the material at the registration mark. The registration mark is detected using one of the fast position latch inputs and a flying shear is then initiated (using the Mint FLY command) to synchronize the knife with the material.

Alternatively, the knife can be geared to the material using the Mint FOLLOW command and the knife synchronised to the material using the position latch value to determine the error. This error is corrected using the Mint OFFSET keyword.

Special Features Used

• Auxiliary encoder for product synchronisation
• Built in software flying shear (flying knife) for position synchronization or software gearing using FOLLOW with a position offset using OFFSET
• High speed position latch to accurately measure product position
