Slitting Pretty

Haste without waste

To prevent the quality of a finished slit roll from becoming lost in the flurry of faster, more efficient operations, suppliers offer waste-saving materials and monitoring strategies.

Wolf highlights PLC-programmed digital drives that allow smoother "soft-start" material transitions on unwind and rewind operations. In addition, newer software allows slitting operations to be hooked up to a modem for trouble shooting, and can maintain a history of any job from the master roll down to the finished roll, he says.
