A metering rod holder assembly for supporting a metering rod in compressive engagement with a surface from which a fluid is to be metered. The rod holder assembly includes a base member having a channel opening to a first face thereof, and a rod bed insert at least partially received in the channel of the base member in spaced relation to a base wall of the channel. The rod bed insert includes a metering rod slot for receiving a metering rod, and a flank engaging surface engaged with at least one flank surface of the base member, the rod bed insert movable from a first position to a second position within the channel.

A creping blade and a preparation method thereof are provided. The creping blade comprises a base, wherein a wear-resistant coating is provided on the top of the base, and a protective layer is arranged below the wear-resistant coating at the contact point between the creping blade and a dryer, and the hardness of the protective layer is lower than that of the surface of the dryer of a paper machine. The creping blade of the invention is advantageous in that the friction portion of working surface has an unlimited area and has a high wear-resistant coating, and the paper impact portion has high wear resistance and high impact resistance, so that the creping blade has a long service life, which can be several times or even tens of times that of the common steel creping blade.

Vibration sensors can be used in paper making systems and methods to determine various aspects of the paper making operation. Vibration sensors, for example, positioned on cleaning blades configured to clean various deposits off of rollers in a paper making system can output vibration data that can be indicative of the vibration of the blade. The vibration data can be analyzed in order to characterize the cause of the vibration and/or the location of the vibration within a paper making system. If the vibration data satisfies a predetermined condition, a corrective action can be initiated. Different corrective actions can be initiated based on the characterized cause and/or location of the vibration in order to effectively improve the operation of the system while minimizing costly system shut downs and major maintenance.
