Application / Task:

During quality control on wallpaper coating machines for glass-textile wallpaper, it is necessary to control the straightness of the wefts at an average of once per hour.

The frequency should be adjusted using a potentiometer as the machine speed can vary between 12-40m/min.

The web width which has to be illuminated is two meters.

Solution / Result:

The decision was made to use the stationary stroboscope RT STROBE 12000 LED (A6-12210). At a distance of 60cm, the whole web width of two meters can be inspected.

Offset weft threads are checked online using the stroboscope at a speed up to 40m/min. In the past, to inspect this offset, the machine speed had to be reduced which led to a loss of production.

It is now possible to carry out the inspection at full speed.
