In an apparatus for positioning the plane (33) of an apparatus platform (8) in an optional inclination and degree of rotation there are included two rotatable, wedge-shaped hollow members (4, 6) adapted to give the selected inclinatior to the plane (33) for a combination of rotational movements. For rotational position there is a third hollow member (27) arranged in mesh with the apparatus table (8), and in mesh with the third member there is a fourth hollow member (31, 41) on which the rotational position is intended to be introduced. |
