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.
Claims38
A reinforced corrugated paper laminate comprising:
- a first paper layer having a plurality of spaced parallel channels formed on the surface of one face thereof, said channels being of a depth less than the thickness of said first paper layer;
- a plurality of longitudinal wires in said channels of said first paper layer, the depth of said channels corresponding to the thickness of said longitudinal wires disposed therein, and the width of each of said channels corresponding to the total thickness of said wires disposed therein, and said channels having a cross-sectional area greater than the cross-sectional area of said wires disposed therein;
- a second paper layer adhesively secured to said surface of said first paper layer having said channels formed thereon to hold said plurality of wires in place between said first paper layer and said second paper layer to form a wire reinforced paper laminate;
- and
- said wire reinforced paper laminate being corrugated transversely of said longitudinal wires.
A reinforced corrugated board comprising:
- a first paper medium, said first paper medium being corrugated to form the corrugating medium of said corrugated board;
- a second paper medium forming an outer facing of said corrugated board, said second paper medium being adhered to the crests of one side of said corrugated first paper medium to form said corrugated board;
- and
- at least said first paper medium being a wire reinforced medium, each wire reinforced medium being comprised of a first paper layer having a plurality of spaced parallel channels formed on the surface of one face thereof, said channels being of a depth less than the thickness of said first paper layer;
- a plurality of longitudinal wires in said channels of said first paper layer, the depth of said channels corresponding to the thickness of said longitudinal wires disposed therein and the width of each of said channels corresponding to the total thickness of said wires disposed therein, and said channels having a cross-sectional area greater than the cross-sectional area of said wires disposed therein;
- and a second paper layer adhesively secured to said surface of said first paper layer having said channels formed thereon to hold said plurality of wires in place between said first paper layer and said second paper layer.
A method of manufacturing a corrugated reinforced paper laminate, comprising the steps of:
- forming a plurality of spaced parallel channels on the surface of a first layer of paper, the depth of said channels being less than the thickness of said first paper layer;
- setting a plurality of longitudinal wires in said formed channels;
- adhesively securing a second paper layer to said surface of said first paper layer having said channels formed thereon to hold said plurality of wires in place between said first and second paper layers to form a wire reinforced laminate;
- and
- corrugating said wire reinforced laminate transversely of the longitudinal extent of said plurality of wires.
A method of manufacturing a corrugated reinforced paper laminate comprising the steps of:
- feeding a first paper web with an adhesive applied to one surface thereof;
- feeding a plurality of spaced parallel papers strips into adhesive relationship with respect to said adhesively coated surface of said first paper web to form a paper laminate, the spacing between adjacent paper strips forming a plurality of spaced parallel channels in said laminate;
- feeding a plurality of longitudinally extending wires into said plurality of spaced parallel channels in said paper laminate;
- feeding a second paper web with an adhesive applied to one surface thereof into overlying relationship with said plurality of papers strips to entrap said plurality of wires between said first and second paper webs;
- setting the adhesive on said first and second paper webs with said plurality of paper strips therebetween to form said wire reinforced paper laminate;
- and
- corrugating said wire reinforced laminate transversely of the longitudinally extend of said plurality of wires.
