Abstract
A creping doctor blade and method of forming such blade including a generally planar creping member having an elongated body with a surface that bears against the drying cylinder. A rake face of the blade extends outwardly relative to a surface of the cylinder when the blade engages the cylinder. The length of the creping member surface approximates the width of the cylinder with the width of the surface corresponding with the wear pad dimension of a conventional blade used in the same processes with a range from about 0.005 inches to about 0.020 inches. The relief face of the blade has an elongated depression with a depth of at least about 0.005 inches formed therein such that as the blade wears over the life of the blade, the width of the surface remains within the range of about 0.005 inches to about 0.020 inches.
