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.
L~invention concerne un procédé de fabrication de lames docteur ou de racles, caractérisé en ce qu~une matière élastomère résistant à l~usure est formée par un processus continu au bout de la lame docteur ou de la racle. Durant la fabrication, l~épaisseur de la matière élastomère appliquée est déterminée en enroulant la lame (contenant la composition polymère appliquée) en forme de serpentin avant le durcissement complet de la composition appliquée. Les spires successives du serpentin sont séparées d~une distance qui est inférieure à l~épaisseur initiale de la composition appliquée, si bien que seule la composition partiellement durcie est déformée par des spires adjacentes du serpentin en prenant ainsi l~épaisseur et/ou la forme souhaitée.
