Grinding unit for grinding curved surfaces has a grinding plate which does not interfere with the to and fro movement of a grinding blade

摘要

Grinding unit has a grinding plate (24) which does not interfere with the to and fro movement of a grinding blade. The point of rotation of a tilting coupling traces a circular path in relation to a tensioned end (20) of a grinding strip (22) so that the path length of the grinding blade between the grinding plate and its two tensioned ends remains the same depending on the curve. Preferred Features: The point of rotation of the tilting coupling can be varied on both sides and a circular path is traced in relation to the tensioned end of the grinding strip so that the path length of the grinding blade between the grinding plate and its two tensioned ends always remains the same depending on the curve.
