Printing Drives & Automation

 

BBL provides a complete solution of ELS for Flexographic & Rotogravure printing machines. Products offered are:

• KEB C6 controller
• KEB F5 series closed loop VFD’s with Ethercat communication option
• Asynchronous servo motors with sine-cos encoder.

Requirement of Printing

• Two nos. of Unwinder / Rewinder requires if manual/ auto Tarrate is in Machine. ( It always available in ELS m/c’s, Laminating & Slitter)
• All motors are with closed loop (Sin-Cos Encoder Feedback)
• Load Cell or Dancer feedback to Maintain the web tension
• Winder Software required or else external PLC/ Diameter sensor required
• ELS require Asynchronous Servo motors which avoids the Main Gear Box & Machine speed goes up to 700 mpm.
