ABSTRACT:
A method and apparatus are disclosed for forming a novel corrugated paperboard web of indefinite length, which web includes a planar facer layer and a corrugated layer the flutes of which extend longitudinally the length of the web. The web is formed by splicing together sections having offset planar facer and corrugated layers of generally equal dimensions, respectively, whereby at one end the facer layer projects beyond the corrugated layer and at the other end the corrugated layer projects beyond the facer layer, the flutes of the corrugated layer extending from one projecting end to the other. Successive sections are spliced together with the projecting facer layer portion of one section overlying the projecting corrugated portion and the facing layer of another section, preferably with the adjacent portions of the corrugated layers of the two sections being in flute-enmeshing engagement. A conventional second web having a planar facer layer and a corrugated layer with transverse flutes may then be bonded in superimposed relation to the first web, thereby defining a third web having successive corrugated layers the flutes of which extend longitudinally and transversely of the third web, respectively.
