ABSTRACT:
The apparatus comprises a metering roller (7) for the metered supply of liquid developer to an applicator roller (10). A profiled roller (11) is provided for pressing the photosensitive stock against the applicator roller. The profiled roller has a cylindrical core (12). The outer surface of the core is completely covered with a coating (13) of a permanently elastic material. The surface of the coating remote from the core is provided with projecting, mutually staggered, substantially conical or pyramidal nubs (14). The nubs are made of the same permanently elastic material as the coating. A pressing roller (17) rests against the profiled roller and, in the direction of travel designated from I to O of the stock to be developed, precedes the point of contact of the profiled roller against the applicator roller. Stock inserted at I is grasped at the point of contact (19) between the pressing roller and the profiled roller and conveyed on. Because of the soft nubs and the relatively light bearing pressure of the pressing roller, the stock to be developed can be shifted or straightened before it comes in contact with the liquid developer. Adjacent nubs have the tendency to spread apart in the region of the points of contact with either the pressing roller or the applicator roller. An additional tightening of the stock to be developed is thereby produced between these nubs. Especially at the applicator roller, this leads to extremely uniform application of the liquid.
