ABSTRACT:
For an improvement of the coating of disintegrator rolls, an accessory wire in the area of a tooth base is coated with a reduced quantity of hard material granulate as compared to the coating on the tooth. With the proposed coating, the advantage is gained that a precoated accessory wire, without damaging the coating, can subsequently be wound on an accessory wire carrier.
