ABSTRACT:
A creping doctor in which a long, thin blade is applied to a roll surface at an angle to the tangent at the line of contact such that the blade presents a wide surface to the product being removed from the roll. A preferred angle is approximately normal to the surface, so that the roll surface tangent and the wide blade surface receiving the product make an angle ranging between acute and obtuse. A bladeholder provides both coarse and fine compliance of the blade to roll surface contour variations. Blades incorporating resilient means distributed along the back edge for cooperating with the bladeholder are also described.
