The FACTS TCC 1600FS Total Calender Control System is designed specifically "on calender" fixed sensor measurements for machine direction and cross direction control of the calender process. 

The FACTS Inc. calender gauge control system brings fast precise control to individual gums, getting within gum walls thickness tolerance in less than 1 calender roll revoution after a specification change or start-up!

The FACTS ON-CAL 3 is a precision gauge for the measurement of nonmetallic calendered materials, such as rubber, vinyl and other plastic materials. It is a non-nuclear, contact measurement gauge that incorporates automatic zero calibration to maintain high accuracy.  No electronics are used on the calender on this simple, robust design.  Being so close to the calender nip, ON-CAL gauges reduce transport lag, thus providing a fast response.

The FACTS Inc. calender gauge control system typically brings the individual gum wall gauges within specified thickness tolerance in les than 1 calender roll revoution after a specification change or start-up!

• Fast due to very short transport delay and no scanning delay
• Accurate and easy to maintain
• Inherently safe – no nuclear source or radiation

Dynamic Target Optimization            

Download Datasheet

The FACTS Calendering Gauge Control System is able to reduce the standard deviation of profile thickness or gauge distribution on calenders.  Reducing the SD allows for tigher control of your ouput, allowing your targets to shift closer to your minimum thickness requirements.  See the brief graphical explanation here.

Cord Spacing Vision System

Download Datasheet

The FACTS vision system which has been designed to detect missing cords as well as provide complete cord spacing measurement.  Optional post calender marking of defect location is available on calender.  The System provides continuous measurement and monitoring of:

• Cord count /spacing
• Crossed, Paired, or Missing Cords
• Measures the entire web width multiple times per second – this is a fraction of the time required by nuclear scanning systems
• Optional continuous marking system of defect location
• Machine direction with transport compensation
• Cross sheet position

Wire Balance Gauge
