ABSTRACT:
The stain removal apparatus uses alternating rows of teeth between a rotor and the housing to clean paper pulp during passage of the paper pulp by the teeth. Check members are employed adjacent the teeth of the innermost row of teeth to preclude accumulations of material in front of the teeth. The check members are of the same thickness as the teeth at points adjacent the teeth while being shaped to merge into the rotor or housing at the end remote from the teeth.
