Nip Pressure Measurement for Industrial Rollers

Innovative machine design & setup tools to confirm nip uniformity and improve yields

Ensuring uniform nip pressure across the entire surface area of those rolls is crucial to producing a reliably consistent product. This consistency is essential not only for maintaining productivity but also for minimizing machine downtime and reducing waste, among other important factors that contribute to overall efficiency and quality in production processes.

Taking routine nip impressions can help identify:

• Nip pressure and uniformity

• Roller alignment

• Proper machine setup

• Crowning (under- or over-crowning)

• Diameter variations

• Deflections

• Blanket & surface wear

Nip Pressure Measurement

The Nip Pressure Alignment Tool™ (NPAT™) is a complete nip pressure and force measurement tool that takes the guesswork out of machine set-up. By using real-time data, the NPAT verifies uniform pressure and nip contact. The tool measures and displays, in real-time, nip widths between 6.35 mm (.25″) and 215.9 mm (8.5″).

Key Features:

• Configurable array of sensing bands

  1. Carrier to keep the bands/housing properly aligned during use

  2. Enclosure for the Evolution™ handle that protects electronics in more rugged applications

  3. Bands that can be easily replaced and serviced in-field

  4. Three sensor model resolutions to support different roll sizes

  5. Easily rolled up for storage

Benefits of Measuring Nip Pressure:

• Clear visual representation of pressure distribution, nip width, and cross width

  1. Ensures proper alignment

  2. Prevents equipment and product damage

  3. Provides quantifiable and credible data

  4. Easily maintained in-field
