Abstract
A linear corrugator formed by at least two rows of discrete presses each of which is formed by mating pairs of press rolls having circumferentially extending mating ridges and grooves adapted to corrugate and consolidate dry formed web, is herein disclosed. The presses of one of said rows are staggered relative to the presses in the other of said rows, the maximum axial length of the nip of each of said presses must be between 5 and 36 inches. A method of consolidating a dry formed web by independently consolidating discrete laterally spaced areas of a dry formed web of at least 40" width, each of said discrete areas having a width of over about 5" but never exceeding 36", thereby to consolidate substantially the full width of said web.
