How Does The Sidewinder Work?
What Makes The Sidewinder Unique?
The Sidewinder’s servo drive is activated only during a web break. Within milliseconds after the break, the servo drive rotates the slotted anti-wrap roller to a given speed as calculated by its proprietary speed-matching algorithm. The servo drive control then matches and follows press speed down to zero all while the anti-wrap section pulls the paper from the last print unit preventing a wrap-up. The patented* “Lock & Roll” roller design ensures positive web captures. The dispensed paper is neatly wound around the anti-wrap roller for easy removal.
