Continuous Thickness Measurement avoids waist of raw material

Production of panels which exceed plus-tolerances results in increase of production cost. This also results in consumption of additional (unneeded) glue and raw material while also extending the press time.

The EWS Thickness Gauges help to optimize the process and to reduce the costs while, at the same time, assuring the quality standard.

If the gauges are located in the sanding line, the service life of the sanding belts is shortened.

The time is long past where panel thickness tolerances have been measured during production by handheld devices. Today, however, such measurement is carried out continuously online. In the majority of plants, quality control is not the first priority for new investment for online thickness measurement. The current trend is to achieve the enormous potential savings in wood raw material, resin and energy consumption. If the upper tolerance level is exceeded, valuable resources are wasted.
THICK-SCAN prevents such losses. It is so robust and reliable that we call it a “work horse”. Another feature is that the system is designed to be installed on a continuous production basis - providing online calibration without a gap between panels (patented).

Function
The measuring heads are mounted opposite to each other and indicate panel thickness continuously during production.

Installation Locations

After the hot press
Before / between / after sander
