APPARAT FOR ANVENDNING VID BEHANDLING AV ETT REGISTRERINGSMATERIAL I ARK- ELLER BANDFORM

摘要

An apparatus for liquid development of latent images on sheets or webs comprises a plurality of applicator stations which sequentially deliver processing liquid to the latent image bearing surface of the sheets or webs. The latter are transported above the respective applicator stations with the concerning surface in downward direction. A controlling mechanism provides for the arrestment of the liquid supply before the trailing edge of the sheet or web has passed over the respective applicator station for the provision of not wetting the backside of the latter. The apparatus is extremely suited for developing latent electrostatic half-tone images on a high polymeric support.
