M-ROTARY

Digital Synchronization for Rotary Knife/Drum Applications

OVERVIEW

The M-ROTARY is a highly intelligent universal controller designed for cut length and repeat length applications.  It has a trend feature that adjusts for variable print lengths, compensating to maintain correct synchronization between the rotary knife/drum and the target material.  For a perfect cut every time, the M-ROTARY's electronic cam capabilities insure matched speed at knife contact while accommodating variable lengths/circumferences.

FEATURES

• No complicated programming required; interfaces with nearly any drive

• 1 millisecond position and speed control loops for precise synchronization 

• Electronic Cam capabilities insure matched speed at knife contact

• Eliminates the need for a mechanical lineshaft to synchronize knife and machine
