摘要:
A doctoring apparatus has a flexible doctor blade advanced longitudinally across a surface being doctored. The doctor blade is feed in a continuous length from a storage cartridge and sequentially supported in a blade holder to apply the blade to a moving surface to be doctored. One or both of a pneumatic blade advancing device and a pneumatically operated clamping system are opened and closed in timed sequence with reciprocation of the blade holder longitudinally shifting the doctor blade in a selected direction across the doctored surface. The pneumatic blade advancing device includes an idler roller and a powered roller that co-operate to indexingly advance the doctor blade along the blade path. The clamping system includes a blade cutter to cut the doctor blade and that drives the cut off end of the doctor blade into a discard container.

The invention provides a doctor blade holder system that includes a doctor blade support structure, an adjustment profiling plate, and a series of adjustment mechanisms. The doctor blade support structure includes an elongated slot for receiving a doctor blade and a separate elongated slot to house mounting hardware. The adjustable profiling plate causes pressure to be applied to the working blade in a continuous manner along the length of the working blade, wherein the profiling plate is mounted to a holder mounting plate with a series of pairs of mounting structures allowing unconstrained flexure, or rotation, of the profiling plate with respect to holder mounting plate around two axes. The series of adjustment mechanisms attach to the holder mounting plate and acting on the profiling plate, wherein the adjustment mechanisms are capable of displacing the profiling plate in a bi-directional manner.
