Abstract
An UV-radiating apparatus for irradiating printing ink on items such as individual articles or portions of material comprises a reflector housing divided into first and second parts in a direction parallel to the longitudinal axis of the radiation source of the apparatus. The two parts are each mounted pivotably about a respective axis parallel to the longitudinal axis of the radiation source between a first limit position in which the reflector housing is open at its side towards the item to be irradiated and a second limit position in which the parts of the reflector housing, with their regions towards the item, form between the radiation source and the path of transportation movement of the item a shield which shields the item from the radiation source. Upon stepwise transportation movement of individual items or a web of material the period of action of the rays on the respective item can be controlled by suitable actuation of the parts of the reflector housing.
