Precision positioning for best slice headbox profiles

Perfect runnability with better sustainability

The Valmet IQ Slice Profiler system combined with Valmet’s multi-predictive cross-direction controls delivers consistent quality and dramatic savings. With precise control of the lip form, less raw material is needed to achieve the target profile quality.

An intelligent actuator controller with a closed-loop stepping motor enables fast and accurate lip positioning. You can make faster grade changes and recover faster from disturbances, improving overall machine efficiency and performance. This in turn increases raw material savings with less waste tonnage after startups.

Consistent basis weight or fiber orientation profile

Featuring a profile control system for adaptive, non-stop positioning of the slice actuator, the IQ Slice Profiler is specially designed for achieving the best possible weight profile that a conventional headbox can produce. A network of intelligent actuators works in unison across the entire headbox. Precise, powerful and self-locking micro-adjusters drive the lip consistently with repetitive accuracy and response.

You can achieve highly uniform basis weight and profiles across the entire width of the headbox, improving end-product quality and machine runnability.  With flatter CD basis weight profiles, printing and packaging machine performance also improves.

IQ Slice Profiler suits perfectly also for fiber orientation control, while dry weight profile is controlled with IQ Dilution

Complete slice system for all headboxes

Experience from over 250 pieces IQ slice system deliveries goes into every IQ Slice Profiler solution. Valmet mechanical know-how and expertise of conventional headbox designs is unmatched.

The Slice actuators are precision-manufactured in Finland and built to last. Robust gear mechanics ensure high precision and fast reaction to controller adjustments over the lifetime of the actuator. The self-locking gear resists deflections from the adjacent positions.
