Camera scanner for high-resolution distortion detection on running textile webs. High power reflex light LEDs illuminate the fabric.
Camera scanner for high-resolution distortion detection on running textile webs. High-performance reflex light LEDs illuminate the fabric. The flash in the opposite housing provides transmitted light.
A high-resolution camera determines the angle of the weft thread of a running textile web.
- Latest camera technology
- Fixed focus (no product-dependent adjustment necessary)
- Automatic scanning of even complicated fabric structures
Distortion detection with camera technology
Several high-resolution cameras placed across the product width scan the passing material web. The angle of the weft thread is determined by FFT analysis.
Interfering signals not agreeing with the frequency of weft threads, courses or rows of tufting are filtered digitally. Only signals relevant to distortion are analysed and the web distortion is calculated automatically and precisely from this.
Suitable lighting versions (refl ex light, transmitted light, power lights) are available also featuring automatic adjustment of the light intensity to different material grades.
