ABSTRACT:
A fiber processing apparatus includes a rotary roll carrying a clothing and having an axis and a length measured parallel to roll axis; and an imaging apparatus which has an illuminating device directing a light beam onto a surface area of the clothing, a camera for sensing the light of the surface area lit by the illuminating device and an evaluating device connected to the camera for examining reflected local light intensity changes during rotation of the roll. There is provided an arrangement for presenting to the camera consecutive areas of the clothing surface along the entire roll length and an arrangement for triggering an operation of the camera and/or the illuminating device as a function of the roll rpm.
