A device for the safe detection of material defects in transparent materials

摘要

A device for the safe detection of material defects in a continuously produced strip of transparent material by means of the testing of an extending transversely to the direction of conveyance, in the transmitted light or reflected light observed, strip of a strip of this material,characterized in that it has the following features:a) a fixing - portal (11) to be tested in the width of the transparent material is used as a carrier of the line cameras (9), wherein the line cameras (9) with respect to their area of coverage without gaps, the width of the cover and the material - belt by means of a linear luminous means (5) with a constant luminous flux and of an adjacent linear luminous means (6) with an oscillating light flux is transilluminated without gaps, and wherein an additional bright field - illumination (8) the test strips in the incident light is illuminated,b) the fastening - portal (11) additionally serves as a carrier of a further line cameras (1), of which the optical axes to the of the line cameras (11) are slightly inclined, whereby also the line cameras (1) with respect to their area of coverage without gaps, said width cover, wherein the line cameras (1) a line grating..
