To permit safe removal of a carrier plate supporting a plurality of doctor blade adjustment motors and gearing elements therefor, and additionally, at the outside of the plate, position indicating and transducer elements, at least one, and preferably two or more support rails are secured to the doctor blade holding frame, extending from the frame in a direction beyond the side of the carrier plate and remote from the side facing the doctor blade, on which the motor and gearing is secured. The plate is formed with openings, forming suspensions (26) slidable on the rails (23) for lateral removal of the plate, together with all equipment carried thereon, and disengagement of electrical contacts (8) from matching contact rails or buses carried in the frame. After such lateral removal to an end stop (29), pivot pins (36) can be engaged in matching openings (32, 33) formed in projecting end portions (31) on the frame and in the plate, respectively, so that, after removal of the stop (29), the plate and all elements thereon can be tilted or tipped for servicing of apparatus or equipment carried thereon. No lifting or complete removal of the plate from the apparatus is necessary, thus permitting one-man servicing operation and insuring safety of the operator by continued support of the heavy plate and the equipment thereon, from the printing machine to which the doctor blade adjustment apparatus is attached. |
