Claims7
In a paper machine, a paper machine deckle means comprising a horizontally elongated C-clip support beam having a pair of spacially separated, parallel support walls and at least one longitudinal guide rail means depending therefrom, an elongated deckle blade body means having a longitudinal guide channel means for receiving said guide rail means when said body means is inserted within a separation space between said support walls, a thin deckle blade means wherein said deckle blade body means comprises a stepped receptacle surface for receiving a section of said thin deckle blade means, said deckle blade body means having smooth and continuously faired surfaces below said support beam onto the surface of said thin deckle blade means.
In a fourdrinier paper machine having a deckle means positioned for delineating lateral edges of a stock drainage pond carried on a traveling screen, said deckle means comprising an assembly of an elongated C-clip having a pair of parallel support walls wherein said C-clip support walls are terminated by respectively opposed guide rails and a deckle blade body configured for secure confinement between said support walls, wherein said blade body comprises a pair of guide channels for corresponding reception of said C-clip guide rails and a stepped receptacle surface, said assembly structured and arranged so that a substantially smooth and continuous vertical surface faces said drainage pond from an upper element of said respective C-clip support walls to a lower element of a thin section blade portion of said blade body, wherein said thin section blade portion of said blade body is of a material composition distinct from other elements of said blade body and is substantially located in said stepped receptacle surface of said blade body.
