A food product slicing apparatus includes a frame and upper and lower drive assemblies. The upper drive assembly includes a belt configured to engage an upper surface of a food product block to be sliced, a plate pivotally mounted to the frame, front and rear wheels supporting the upper belt, the front wheel rotatably mounted to the plate and a drive member engaged with the plate. When the drive member is engaged, the plate and the front roller pivot relative to the frame and to the rear wheel. The lower drive assembly includes a belt configured to engage a bottom surface of the food product block.

A mass-balancing arrangement comprises an adjustably pre-loaded spring member (14); a pivotably mounted lever (16; 31) for compensating different inertial forces in combination with the spring member (14); a first drawing member (24) connecting a movable mass to the lever (16); a second drawing member (17) connecting the spring member (14) to the lever (16); and a first roller (15) for deflecting the first drawing member (24). The lever (16; 31) has an upper lever arm (19; 32) and a lower lever arm (20; 33), one being sector-shaped and the other cam-shaped. The upper lever arm is connected to the movable mass through the first drawing member (24), and the lower lever arm is connected to the spring (14) through the second drawing member (24). Two torques produced at the upper and lower lever arms are kept balanced. The balanced mass may be an object carriage of a microtome.
