What is the primary function of the anti-roll plate?

When a tissue section is cut in microtomy, it tends to curl or roll as it leaves the blade. The anti-roll plate provides a flat, supportive surface right next to the knife edge, against which the freshly cut section rests as it exits. This keeps the tissue from rolling toward the blade, guiding the section into a stable, straight plane and yielding a clean, uniform cut that lies flat on the slide. It isn’t primarily about cooling the blade or directly setting thickness; those functions come from other parts of the microtome and its controls.
