Maxson Offers Accumulating Festoon
- Published: Tuesday, 22 January 2013 08:30
WESTERLY, RI | Maxson Automatic Machinery Co. offers an accumulating festoon said to allow inline sheeters to match closely the speed of downline processes, thereby 
maintaining accurate sheet length. The system provides a closed loop tension control for the roll stand, accommodating immediate speed changes that company says would otherwise be impossible because of the weight of the unwinding roll.
The design employs an air cylinder that spreads the festoon rolls apart or draws them together, a transducer, an electrical–pneumatic converter, and the roll stand’s tension control to automatically compensate for rapid changes in web speed. As the rolls get closer together, the roll stand brake pressure is reduced. As the accumulator’s rolls spread apart, the unwind tension is increased.
The e-p converter changes the roll stand’s tension control setting to a pneumatic output that adjusts the air pressure in the cylinder, tightening or slackening the web around the accumulator rolls. A transducer monitors the movement of the roll frames feeding back the information to the roll stand’s tension controller adjusting brake pressure until the preset tension is regained.
