METHOD AND APPARATUS FOR INTERMITTENT COMPRESSION OF FIBROUS MATERIAL TO AID REMOVAL FROM A FILTER SURFACE of the Invention A method and apparatus is provided for aiding in the removal of a fibrous material sheet from a filter surface. An intermittent pattern of compression is impressed upon the sheet to cause it to be released from the filter surface so that it will not stick to the filter surface nor split when it is contacted by the doctor device which guides it away from the filter surface. The spacing and the geometry of the compression pattern are determined according to the pulp characteristics and the operating conditions of the filter.
