ESI's Accufly® in-line cutting system offers innovative technology with high accuracy cutting by incorporating a servo driven stop/go feeder with fiber optics for cut-to-length signaling.  Length is set by adjusting the fiber optic bridge assembly, or utilizing the servo feedback from the feeder motor. Just prior to the set length being reached, the feeder belts ramp down to ensure proper cut length positioning without overshoot. When the fiber optic beam is broken, the feeder belts stop and the servo driven flyknife is cycled, resulting in a square cut and high accuracy cut length.  Because the feeder is maintaining a loop ahead of the Accufly, the product is fed without tension, ensuring very accurate cut lengths, especially on highly elastic profiles such as rubber wiper blade elements. ESI has successfully utilized this unique proven process in numerous applications for over 20 years and it is the foundation of our complete "ACCU" series of fabricators, saws and flyknives.
