ABSTRACT:
A twin wire paper former incorporating a forming shoe having a curved solid forming surface across which the forming wires pass with one of the wires in direct contact therewith and the other sandwiching the stock from which the paper is to be formed therebetween. The tension in the other wire drives water from the stock contained between the two wires, out through the other wire, and the shoe is vibrated thereby to reduce the friction between the wire contacting the shoe, to reduce wear of the contacting wire and to improve drainage.
