A method in a paper or board machine for confining a pulp flow coming from the headbox ( 1 ), in which by at least one deckle part ( 2 ) being above the wire in the operating position the pulp flow coming from the headbox is confined in the lateral direction in the edge area of the wire ( 3 ). In the method, by a support part ( 50 ) impervious to liquid being below the wire ( 3 ) together with the deckle part ( 2 ) into connection with which liquid is brought, a pressure effect is provided which furthers the sealing between the deckle board ( 2 ) and the wire ( 3 ) and intensifies the lubrication of at least one sealing surface of the deckle ( 2 ). The invention also relates to an apparatus.
