Abstract Wire reinforced paper products wherein wires are affixed to a paper layer or included within a paper structure with at least one paper layer conforming to the contour of the wires to supplement the rigidity produced by the wires and a corrugated paper structure including wires disposed therein. The paper products are manufactured in continuous processes which enable the use of one or two sets of parallel wires, the latter producing a wire grid structure. In the manufacture of corrugated structures one or two sets of wires may be included in the corrugated portion and the overlying layer or layers and in so doing the structural strength and moisture resistant characteristics of the resultant corrugated board may be increased several fold without materially increasing the cost of the board as compared with board using relatively heavy paper in order to achieve increased strength.
A double faced corrugated board comprising a corrugated medium formed of a layer of paper having parallel reinforcing wires adhered to one side thereof, said reinforced paper layer and wires being corrugated transversely of said parallel wires to form said corrugated medium, and a first outer layer of paper adhered to the crests of one side of said corrugated medium, and a second layer of paper adhered to the crests of the other side of said corrugated medium to form a double faced corrugated board.
