CA 2173918

A fiber processing apparatus includes a plurality of serially-arranged fiber processing components for forming and advancing a fiber web and for gathering the web into a sliver. Some of the components are spaced by a clearance from one another such that the fiber web, while passing from one of the components to an adjoining, spaced component has a length portion unsupported by either of the adjoining components. There are further provided an imaging apparatus which has an illuminating device directing a light beam onto a surface area of the unsupported length portion of the running web; and a camera for sensing the light of the surface area lit by the illuminating device. An electronic image processing unit is connected to the camera for examining signals received therefrom.
