摘要： A blade for creping a paper web from a Yankee cylinder surface is made of a steel substrate having a thickness of 0.7 mm-2 mm. The steel substrate is covered by a cermet coating that forms a working edge adapted for contact with the surface and a web impact area upon which the web impacts during creping. The cermet coating includes chromium carbides and tungsten carbides in a nickel based metal matrix. The cermet coating has a porosity of 1100 HV0.3.

摘要： A doctoring apparatus for doctoring a roll surface comprises a doctor blade, a blade holder for applying the doctor blade to the roll surface, and a doctor back having a support surface on which the blade holder is adapted to slide. A locking bar is subdivided into multiple mechanically interlocked segments and is mounted by fasteners on the support surface of the doctor back for movement lengthwise in opposite directions between locked and unlocked positions. The locking bar is configured and dimensioned to fit loosely within a groove on the underside of the blade holder. In its unlocked position, the locking bar permits the blade holder to slide on the doctor back support surface into and out of an operative position adjacent to the roll surface. In its locked position, the locking bar releasably secures the blade holder in its operative position.

摘要： Doctor blades are provided for multiple positions within a paper or board making machine. A single doctor blade of a standard length or a reel of doctor blade material has markings which permit a variety of doctor blade sizes to be readily cut. If a standard length doctor blade is used, the length of the blade is chosen to be at least as long as the longest doctor blade required for a particular papermaking machine. If the material is in a reel, the markings may be at regular numbered intervals. If a pattern of rivets is connected to the blade, and the rivets must have a given relationship with a blade holder, blade length may be marked out in such a way that some blade material is discarded in order to position the rivets when shorter blades are cut from the blade reel.

摘要： Doctoring apparatus for doctoring a moving work surface is disclosed as including novel extended-life blade structures and combined therewith blade holding apparatus for supporting a blade for engagement with the work surface including means acting on the blade differentially along the length thereof to cause the blade to conform to deviations in the work surface. Blade holding apparatus is disclosed which minimizes the width-wise deflection of a supported blade and thus maximizes its length-wise flexibility. Extended-life blade embodiments are disclosed which include means defining on an end surface of a tip portion of the blade a narrow relatively wear-susceptible land having along one side thereof a leading edge for making initial line contact with a work surface, and a relatively wear-resistant structure adjacent the land on the side thereof opposite the leading edge. Upon contacting a work surface, the land wear relatively rapidly to break in the blade before contact is made between the wearresistant structure and the work surface, the wear-resistant structure wearing thereafter relatively slowly.

摘要： A round-rod scraper is used to regulate the thickness of a coating on paper. The scraper is carried in a holder which is attached to one end of a pivotally mounted lever whose other end is carried by a bracket. The bracket also carries a tube filled with compressed air bearing against the lever through the intermediary of a plurality of independently displaceable pressure elements. The bracket itself is capable of having its position adjusted with the individual pressure elements held in fixed positions relative to one another.
