Slitter/Scorer Alignment System
The Fife Slitter/Scorer alignment system is compact and easy to install. The system assures accurate chasing of the slitter/scorer knives to the board at lines speeds up to 1,000 fpm. The result? Reduced side trim waste, reduced order-change waste, consistent finished quality and greater productivity.
Installed on the slitter/scorer, the D-MAX Series Web Guide Controller works as a closed-loop system detecting edge and center guide information from the DAC-004 Diode Array camera sensor and directing the guide structure to make the correct alignment adjustments prior to the slitter/scorer function.
Key Features:
- No large, bulky cabinets
- Eliminates need for mechanical or electronic position feedback circuitry
- High chasing accuracy by reference to web edge or printed line with closed-loop electrohydraulic proportional control
- Unaffected by width variations
- No need for operator involvement during order changes due to wide-angle lenses that eliminate need for adjustments – continuously controlled production from order to order.
- Virtually maintenance-free DAC-004 camera sensor protected against dust and condensation and unaffected by ambient light.
Tension Control for Slitter/Scorer Alignment Systems
Cygnus Tension Control
The Cygnus compares this actual tension reading to the set point (tension specified) then sends directs to the brake, giving it direction to engage/disengage, etc. The tension system on a bridge guide is handled in a continuous loop. The nice thing about Cygnus is that it includes Weightless Load Cell Calibration, multiple languages and is the most accurate, robust control available.
TSU Under Pillow Block Load Cells:
TSU Load Cell are easy to install and ruggedly constructed with built-in mechanical overload stops in both force directions, and will stand up to mill duty. A full Wheatstone bridge arrangement is incorporated in each load cell for the most accurate means of measuring web tension. These load cells accurately measure the total force on the entire roll created by tension in the web, and the readout will be precisely displayed no matter what the position of the web.
Key Features:
- Rugged industrial construction
- Positive overload stops in both compression and tension modes of operation
- Four foil strain gauges in a full Wheatstone Bridge
- Low cost with high quality components
- Simple installation
- Sensing actual web tension
