Abstract:
1. A treatment apparatus that is mountable on a rotor blade of a windmill for treatment of the rotor blade, the rotor blade having a longitudinal axis and opposing leading and trailing long side edges extending in the longitudinal direction, the apparatus comprising: a displacing means configured to displace the treatment apparatus along the rotor blade in the direction of the longitudinal axis of the rotor blade; a guiding means configured to engage the rotor blade and guide the treatment apparatus relative to the rotor blade while the treatment apparatus is displaced, whereby the guiding means guides the treatment apparatus along the rotor blade in a directional manner; and a treatment means configured to provide treatment to the rotor blade; wherein the guiding means is configured to engage with opposite leading and trailing long side edges of the rotor blade via automated adaptation to a varying dimension between the leading edge and trailing edge of the rotor blade along the longitudinal axis; and wherein the guiding means is flexibly suspended to engage an area adjacent the leading edge of the rotor blade such that the guiding means is configured to automatically adapt to the varying dimension between the leading edge and trailing edge of the rotor blade along the longitudinal axis.
