摘要

The clearing disc is formed as a flat disc with a cogged circumference (86) where the troughs (80) between the teeth extend inwards from the outer edge by less than 10% of the diameter of the disc. The troughs between the teeth can be flattened on the circumference of the disc. The troughs follow a circular line whose centre points are between the ends of adjoining teeth. The radial extension of the teeth is between 1.3 cm and 2.6 cm. The thickness of the disc is between 6 and 10 mm.
