The specification discloses a method of making, and operating, a ribbed member for the treatment of fibrous suspensions passed between the ribbed member and a corresponding ribbed member while the members rotate relatively. According to the disclosure the ribs are made from 1 1/2 to 5 times the normal heighth of ribs on such members, while the grooves between the members are partly filled with a synthetic material solidified in situ in the grooves. As the ribs wear down in operation, the height of the synthetic material in the grooves is reduced to restore the groove depth for efficient operation of the members. |
