Abstract: A reinforced corrugated laminate and the method and apparatus for the manufacture thereof which includes forming a corrugated layer with reinforcing wire elements with at least certain of the wire elements being positioned normal to the corrugations and applying planar webs to one or both sides thereof by adhering them to the crest portions of the corrugated layer and combining the planar and corrugated structures with cushioning and resilent foam materials.

Abstract: A reinforced laminate and the method and apparatus for the manufacture thereof which includes the embedding of reinforcing wire elements in plastic layers and plastic laminates to provide reinforced structures, producing a reinforced corrugated laminate including a corrugated layer with plastic layers applied to one or both sides thereof, producing a wire grid, corrugating the grid and applying overlying plastic layers and combining the planar and corrugated structures with cushioning and resilient foam materials.

Abstract: Improved laminated paper products are disclosed in which different paper layers are adhesively secured together with hot melt adhesives. According to one aspect of the invention, the hot melt adhesive is provided on less than the entire surfaces being joined to define an adhesive coated portion which is of an area or size sufficient to adhesively secure the paper layers together and an uncoated section which is of an area or size sufficient to permit evaporation of water across the facing surfaces of the first and second paper layers. Such a laminated paper product is particularly useful in the manufacture of corrugated cardboard products in which a paper liner is adhesively secured to the crests of a corrugated medium with a water-based emulsion adhesive. In such corrugated products in which the disclosed laminated paper product is used as either the liner or the corrugated medium, the water is capable of evaporating through the laminated paper product.

Abstract: Improved wire reinforced paper products are disclosed in which a plurality of parallel spaced wires serve to strengthen and reinforce the paper structure. The improved paper structure includes a first paper layer having a plurality of parallel spaced channels formed on the surface of one face, a plurality of wires, and a second paper layer. The spaced channels are of a depth less than the thickness of the first paper layer. The plurality of wires are set in the channels of the first paper layer, and the second paper layer is adhesively secured to the surface of the first paper layer which has the channels formed thereon to firmly hold the plurality of wires in place. A method of manufacturing such wire reinforced paper products is also disclosed.

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.
