Abstract
There is disclosed a method for the manufacture of coating or doctoring blades, wherein an elastomeric wear-resistant material at the blade tip is provided in a continuous process. During the manufacturing, the thickness of the applied elastomeric material is determined by winding the blade (containing the applied polymer composition) into a coil before the applied composition is fully cured. Successive turns of the coil are separated by a distance which is smaller than the initial thickness of the applied composition, such that the only partly cured composition is deformed by adjacent turns of the coil into the desired thickness and/or shape.
