Quality Measurement and Control Systems for Calendering Industry
Seltek Quality Measurement and Control Systems (QCS) are used for different applications in Calendering industry such as:
- PVC Calender
- Rubber Textile Calender
- Rubber Wire Calender
- Rubber Gum Calender
These systems measure certain quality parameters of the Calendering products on-line such as:
- Total basis weight (grammage)
- Gum weight
- Total thickness
- Gum thickness
- Front / back surface to wire thickness
- Wire positions and counts
Nucleonic, x-ray, laser principles are used for design of these sensors. Measurements are non-contact type.
O-Frame is the most common scanner used. Single beam scanners and C-Frame scanners are also available.
Electronics enjoy a distributed architecture and the cabling between the frame and the main CPU is minimal, being restricted to Ethernet cable and power cable.
Machine Direction Controls as well as Cross Direction Controls are available. For this, gap control, roll bending control and cross axis control can be used.
HMI (Human Machine Interface) is operator friendly. Fast and slow trend plots, profile pages, recipe page, rich maintenance page, controls page, roll report page, alarm and event log pages are all very easy to learn and self guiding. Roll data is stored numerically in MS SQL® database, which can be converted to Excel® format for use by mill staff.
