Rakelvorrichtung für Tiefdruckmaschinen

In a wiping apparatus, a piston rod actuating end (38) of a fluid pressure cylinder (37) is pivotally coupled to each eccentric bearing (25) for supporting the wiping roller (26), and the fluid pressure cylinder is supported by an adjusting mechanism for slightly moving in an extendable direction of the piston rod. A doctor blade holding member (43) and a press-side support member (41) are coupled by a plurality of fixing screws (44). The support member is reciprocally supported relative to the press side in a attachment/detachment direction of the doctor blade. The eccentric bearings (25) and both ends of the support member (41) are coupled by cam mechanisms for interlocking pivotal movement of the eccentric bearings with reciprocal movement of the support member. A doctor blade contact pressure fine-adjusting mechanism reciprocates the holding member (43) with respect to the support member (41). Belleville springs (48) are inserted between heads of fixing screws and the doctor blade holding member. Compression springs (51) having a lower spring constant than that of the belleville springs are inserted between the belleville springs and the heads (44b) of the fixing screws. Fixing screw removal preventive stoppers (52) are arranged. A doctor blade contact pressure fine-adjusting unit is arranged between the holding member and the support member to reciprocate the holding member.
