Abstract

A sheet material (6) is passed between a pair of forming rolls (7, 8) having working surfaces with form­ ing teeth of a wave-shape which has a periodicity within two mutually perpendicular sections. The rolls are constructed from elements in the form of helical spur gears (3) keyed on a common shaft (5) and may be interspersed with straight spur gears (4). This per­ mits the continuous formation of a structural material having a bidirectional periodicity, that is a material (1) having a wave-form construction within each of two mutually perpendicular sections. The pitch of the wave-­ form can be altered by changing the depth of action between the rolls. Such bidirectional material can have a structural performance comparabe with that of a honeycomb sandwich material and has many other uses.
