Device for detecting surface quality of material transported on conveyor subjects surface of material to pressurized gas, detects/assesses surface quality of resulting local surface deformations

摘要

The device has a nozzle (2) that subjects the surface of the material (4) being transported to pressurized gas and an arrangement for detecting or assessing the surface quality of the resulting local deformations of the surface of the material being transported. An optical arrangement, preferably a camera, or a distance sensor is used to detect the deformations. Independent claims are also included for the following: a method of detecting the surface quality of a material being transported on a conveyor.
