Tekscan's Nip Pressure Alignment Tool
- 1. Increase the Quality of Product & Process with the Nip Pressure Alignment Tool™
- 2. NIP PRESSURE ALIGNMENT TOOL Increase yields and reduce waste by measuring nip footprint & relative pressure distribution between rollers
- 3. NIP/ROLLER INDUSTRIES Printing/Paper • Pull Rollers • Tension Rollers Paper/Metal Mills • Iron, Steel, Copper, etc. • Coasters Packaging • Laminators & Converters • Die Press • Film
- 4. NIP/ROLLER APPLICATIONS • Machine Setup • Preventive maintenance • Misalignment • Crowns • Diameter Variations (wear) • Deflections • Machine Comparison MACHINE SETUP / QUALITY CONTROL Roller thin wall shell deflection Roller misalignment Heavy Crown Light Crown Crown Roller beam deflection
- 5. WHY USE THE NPAT? • Take the guesswork out of machine set-up • Capture real-time data to verify pressure distribution and nip contact • Quantify tool integrity • Improve process and efficiency • It’s affordable and easy to use!
- 6. FEATURES & BENEFITS Sensor band: • Two sensor model resolutions to support different roller sizes •Standard band measures pressures from 25-4500 psi (available in custom pressure ranges up to 7500 psi) Rugged Electronics: • Single set of electronics covering a large area •Connected to a standard Evolution handle; one USB connection to PC •Protected by ruggedized enclosure Sensor Band Interconnect: • Bands are easily replaced and can be serviced in-field Carrier: •Polycarbonate sheet that supports & aligns sensor bands/connectors for easy alignment when taking measurements •Easily rolled up for storage & lays flat when unrolled •Includes a removable plastic sleeve that protects from wet environments Configurable Sensor: • Large sensor with multiple sensor bands whose length and spacing can be configured to match the dimension of the nip being measured •Bands can be spaced to show pressure footprint and nip width across the roller
- 7. SOFTWARE Real-time display of pressure profile on bands across roller Graph Nip Width & Relative Force of each sensing band Center of force cursor verifies equal load from bearings Compare real-time data with reference measurement previously taken Color scale of pressure values Data Provided: • Relative Pressure • Average Nip Width
Editor's Notes
- New stock photo of a paper mill Metal mills lower priority Rollers are used for making paper, printing images and laminating material. The contact between these rolls is called a nip. To achieve high yields, fast speeds, and other desirable behavior, the nip needs constant adjustment. Tekscan’s very thin, flexible sensors easily fit between two rollers in the same way as the media being processed, giving you a real-time view of the nip. Measuring and adjusting the nip width and pressure profile along the roller axis are critical to machine design, alignment adjustments, preventative maintenance, and efficient production.
