Drive apparatus for the planar displacement of a platform

摘要

The platform (4) is supported by two carriages (2,3) which can be driven simultaneously or separately along guide rails (11) oriented along an axis (X). At least one of the platform runners (41A,41B) is orientated at an angle different from 90o relative to the axis (X). The displacement of a tool carrier (5) mounted on the platform can be obtained only by relative or simultaneous displacements of the two carriages on the guide rails.
