초록 ▼

The present invention relates to a doctor blade comprising: a body having a thickness, a sharp leading side, a trailing side, and working end comprising a bevel surface, wherein the bevel surface is defined by a leading edge and a trailing edge, and wherein the Ra of the bevel surface is from about 1 μ-in to about 7 μ-in. The present invention further relates to a method of removing a material from a surface of a piece of equipment, the method comprising providing a material on the surface of the piece of equipment; providing a doctor blade adjacent to the surface of the equipment, the creping blade having a working end including a leading edge, which is disposed closest to the surface of the equipment, a trailing edge disposed farthest from the surface of the equipment and a bevel surface disposed therebetween; passing the surface of the equipment past the doctor blade or the doctor blade past the surface of the equipment such that the material impacts the doctor blade and at least a portion of the material is removed from the surface of the piece of equipment; and passing the removed material over the bevel surface of the doctor blade wherein the Ra of the bevel surface is from about 1 to about 7 μ-in.
