摘要： A conditioning doctor blade (11) for a fiber web machine contains a number of reinforcement fiber layers (24, 26) laminated on top of one another into an epoxy matrix (20), and silicon carbide particles (21), so that the reinforcement fiber layers (24, 26) have formed a fiber core (22) and surface fiber layers (23) on both sides of the fiber core (22). There is less epoxy matrix (20) in the fiber core (22) than in the surface fiber layers (23).

摘要： A doctor for a paper machine that according to some implementations includes a blade, a wearing element located in or on the blade so that at least a portion of the wearing element is exposed to wear as the blade is worn, and a reading element positioned in proximity to the wearing element. The reading element is configured to emit a magnetic signal to excite the wearing element and the wearing element is configured to respond to the magnetic signal with a magnetic response signal. The reading element is in turn configured to receive the magnetic response signal, the magnetic response signal comprising a frequency that varies with the wear of the wearing element such that the frequency of the magnetic response signal is representative of the wear of the wearing element.

摘要： 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.
