ABSTRACT:
A creping doctor blade and method of forming such blade including a thin flexible generally planar creping member having an elongated flexible, substantially prismatic body having a relieved substantially planar engagement surface adapted to bear against the drying cylinder. A rake face of the creping doctor blade extends generally outwardly relative to a surface of the rotatable drying cylinder when the creping blade engages the cylinder and the length of the substantially planar engagement surface is generally equivalent to the width of the drying cylinder with the width of the substantially planar engagement surface being selected so as to correspond to the wear pad dimension of a conventional blade used in the same processes and is generally in a range from about 0.005 inches to about 0.020 inches with the relief face of the blade adjacent to the rotatable drying cylinder having an elongated depression having a depth of at least about 0.005 inches formed therein such that as the blade wears over the majority of the life of the blade, the width of the substantially planar engagement surface remains within the range of about 0.005 inches to about 0.020 inches.
