ABSTRACT:
Disclosed is a traversing microtome having a base (10) and a movable carriage (13). A blade holder (12) with a blade (16) is mounted on the base (10), and an object holder (14) is mounted on the carriage (13). To carry out the cutting process, the carriage (13), together with the object holder (14) and the object (15), is moved against the stationary blade (16). Between the guide rails (18,18') of the base (10) and the carriage (13) a bearing gap (30) with a width of a few microns is created by means of air bearing elements (21,21'), and consequently only a minimal force is required to move the slide (13). Between the air bearing elements (21,21'), magnets (22,22') are arranged so that their attracting forces act against the air pressure of the air bearing elements. In this manner, the force needed to arrest the motion of the carriage (13) at any given location of the guide rails (18,18') is extremely low. The carriage (13) cannot be moved when the supply of air is interrupted. The air bearing elements are suspended in the manner of a pendulum and are adjustable in height; the latter is true for the magnets (22,22') also. In view of the air bearings, no lubrication is required for the guide rails (18,18').
