Claims (7)
1. System för bestämning av färgen hos en rörlig material-bana som är under tillverkning, kännetecknat av att systemet omfattar a) organ som försätter banan i rörelse, b) organ för att belysa banan, c) detekteringsorgan som placerats pä den ena sidan om banan sä, att de mottar ljus som kommer frän provmaterialet, d) organ för mätning av intensiteter hos bestämda frekvenser hos ljuset som mottagits av detektorn, och : ·': e) bakgrundsorgan för att reflektera ljuset frän ett ställe bakom banan mot banan, vilka bakgrundsorgan konstruerats sä att banan rör sig i relation till det sanana och att det in-nefattar ett bakgrundsmaterial som är väsentligen likt ba-nans material, och att bakgrundsmaterialet är ätskilt frän banan.
2. System enligt patentkravet 1, kännetecknat av att banan utgörs av papper och att bakgrundsmaterialet bildas av en dyna av ett flertal pappersark.
3. System enligt patentkravet 1, kännetecknat av att bak-grundsorganen är belägna pä den motsatta sidan i relation till materialbanans detekteringsorgan. 9 87608
4. System enligt patentkravet 1, kännetecknat av att bak- grundsmaterialet besitter väsentligen samma spridningskoef-ficient som banans material.
5. System enligt patentkravet 1, kännetecknat av att bak-grundsmaterialet besitter väsentligen samma absorptions-koefficient, fluoresceringsgrad och spridningskoefficient som banans material.
6. System enligt patentkravet 1, kännetecknat av att bak-grundsorganen omfattar en kvartsskiva, vilken är placerad mellan den rörliga banan och bakgrundsmaterialet.
7. Förfarande för bestämning av färgen hos en rörlig mate-rialbana som framställs, kännetecknat av att vid detta för-farande a) den rörliga banan belyses, b) ljus som kommer frän den rörliga banan detekteras, c) intensiteterna hos bestämda frekvenser av det detekterade ljuset bestäms, d) bakgrundsorgan konstrueras genom att bilda utgäende frän ett antal standardmaterialark en dyna och placera den samma ätskild frän den rörliga banan, och bakgrundsorganen och banan försetts i inbördes rörelse, och e) ljus reflekteras medelst bakgrundsorganen frän ett ställe bakom den rörliga banan mot den rörliga banan.
