Abstract
Apparatus for treating a surface comprising a first frame adapted to be moved across the surface to be treated, a sliding frame mounted on and adapted to slide relatively to the first frame in a direction perpendicular to the surface to be treated, an adjustable frame mounted on and adapted to be adjusted relatively to the sliding frame in a direction perpendicular to the surface to be treated, a tool carrier mounted on the adjustable frame and means for maintaining the sliding frame at substantially a predetermined distance from the surface to be treated.

Apparatus for treating a surface, comprising:
- a first frame adapted to be moved across the surface to be treated, a sliding frame mounted on and adapted to slide linearly relatively to said first frame in a direction perpendicular to the surface to be treated, an adjustable frame mounted on and adapted to be adjusted linearly relatively to said sliding frame in a direction perpendicular to the surface to be treated, a tool carrier mounted on said adjustable frame in such a manner that the position of said tool carrier can be adjusted relatively to said adjustable frame in a direction parallel to the surface to be treated, and means for maintaining said sliding frame at substantially a predetermined distance from the surface to be treated, which means comprise surface following means carried by said sliding frame and cooperating with said adjusting means arranged between said first frame and said sliding frame.
