Abstract
Apparatus and method are described for measuring and controlling the crimp characteristics of a moving crimped tow. A light source illuminates a section of the moving crimped tow and at least one progressive scanning camera acquires a non-interlaced video image of the tow. The acquired image is digitized and a processor analyzes the non-interlaced image. Crimp characteristics are derived based on this analysis.
