  • Method of making reinforced corrugated board and product therefrom
    Patent number: 5496617
    Abstract: A method of making a reinforced corrugated board and product therefrom whereby both a single-faced corrugated board and a reinforcing strip are passed through the same adhesive station, before being secured together with a facing liner. The reinforcing strip is passed below the path of the single-faced corrugated board so as to coat both the top and bottom surfaces of the reinforcing strip and the upper, faced surface of the corrugated board. The members are then passed together with a lower facing liner through a pair of pressure rollers serving to secure the layers. The reinforcing strip may also be narrower than the width of the corrugated board and facing liner, and furthermore, a plurality of reinforcing strips may be used.
