Rotary knife heads
Rotary knife control and drive systems for high speed transverse cutting applications with variable cut measurements.
This application is generally used to laminate product in continuous at high working speeds from a mother reel.
The material to be cut travels at a preselected constant speed, being the rotary knife the one that will vary its speed to synchronize itself and cut at the specified size.
At the cutting point, the rotary knife speed is the same than the material, while at other times the rotary knife will vary its speed to maintain the desired cutting size, being able to perform up to 700 cuts per minute, depending on the application.
With the implementation of registry or printed mark sensors, the cutting can be synchronized with the printing process.
