Edge detection of a fabric The lateral position of a wide-meshed fabric should be controlled in a range of 20mm. At this, the necessary accuracy should be ±2mm and the bandwidth of the analogue output signal has to be a few Hz. |

Double sheet control Metal plates should be removed from a stack with a robot. The robot sucks the metal sheets one by one and it should be avoided for safety reasons to move two metal sheets simultaneously. A sensor should detect double sheet not from the top but from the side. Furthermore, the system should be adapted automatically after a change of the type of metal sheet (different thickness or different metal). |

Color-gloss differentiation of leather and leather imitations in the automotive interior field In the automotive interior field the different materials looks sometimes very similar. For a proper differentiation of the different products color-gloss detection should be used. |

|
Differentiation of leather and leather imitations in the automotive interior field Sometimes a color differentiation between interior materials with exactly the same color and the same gloss factor is not possible, even with the best color sensor. Thus another sensor must close this gap. Indeed the different materials may have the same color and the same gloss, but a different structure as shown in the photos. |

Control of margined abrasive belts Different sanding belts are equipped with a margin and this margin has to be controlled. The margin can be present on the sanding side of the abrasive belt or on the rear side. Furthermore the margin can be darker than the rear side but mostly it is brighter than the sanding surface. Nevertheless there is a sufficient difference in contrast between the margin and the rear side or the sanding side. |

Measurement of length of metal collapsible tubes during the production process During the production of metal tubes, the length of the tubes must be controlled, because of the previous cutting process of the tubes. The accuracy of the metal tubes should be in a range of a tenth of a millimeter. |

Kontrola vzporednosti tekočih trakov v lesni in paprni industriji V lesni industriji, npr. pri proizvodnji t.im. MDF plošč (medium density fiberboards) kakor tudi v papirni industriji se uporabljajo posebni tekoči trakovi. Vzporednost le-teh mora biti v tolerancah +/- 0,2 mm, pri čemer pa se vertikalna pozicija le-teh lahko spreminja v območju +/- 2 mm. Material iz katerega so izdelani trakovi je lahko nerjavno jeklo ali plastična tkanina. Lateral position control of conveyor belts in the wood and paper industry In the wood industry (during the production e.g. of MDFs = medium density fiberboards) as well as in the paper industry, special conveyor belts are in use. The lateral position of the band material must be hold in a range of ±0.2mm, whereas the vertical position can change in the range of ±2mm. The material of the conveyor belt is either stainless steel or plastic fabric. |
