Abstract
The invention relates to a grinding tool for grinding a leading edge of a wind turbine blade. It comprises two parallel shafts of which at least one is rotationally driven and a frame for holding the two shafts in a fixed mutual relationship. An annular abrasive belt is arranged around a tension device mounted to the frame and guides of which there is one on each of the two shafts. The abrasive belt runs in a plane perpendicular to the shafts and has a longer length than an imaginary curve formed by outer surfaces of the tension device and of the guides. The grinding tool further comprises two abrasive belt retainers movably mounted to the frame. They are shaped and arranged to move between a retaining position in which they retain the abrasive belt along at least parts of the abrasive belt which is in contact with the guides, and a release position in which they are out of contact with the abrasive belt.
