METHOD FOR INSPECTING THE QUALITY CRITERIA OF FLAT TEXTILE STRUCTURES EMBODIED IN A MULTILAYER FORM ACCORDING TO A CONTOUR

摘要

The present invention relates to for standard flat textile structures of checking on the quality in multilayer profile, more particularly to weaving, suture, knitting suture or non-woven constructions, it is preferable to provide, especially section or hole or form band at separation, in particular for manufacturing air bag. Image is executed with the help of the method for the present invention forms detection methods, especially optical check means, preferably CCD-array line array video cameras or camera. Relative motion between checks and generates structure with camera, which, which is arranged at the distance of region and restriction, forms the console on the preferred general planar surface of detection methods from image or in test strip. The analysis of texture structure is according to dividing method. This characteristic, such as center of gravity, the surface, main shaft etc. is to the relevant identical texture of section of difference. The characteristic is defined on the basis of the structure and corresponding structure of univocality system spatial coordinates same type, the system is non-variable relative to torsion, reflection, and the system of stretching/compressing and deflection can determine measurement point. In order to determine the coordinate in the system, in addition to described segmented characterizing, position and direction identification thread these be intentionally introduced structure be consider. The related control of quality report relative to distance for according to the quality requirement of these measurement points recorded, by system according to manufacturer or consumer preferably in distant with marginal critical area.
