The present invention generally relates to systems for corrugating extruded sheet material. A system for forming an extruded corrugated sheet generally comprises an extruder and a corrugating roller region. The corrugating roller region may comprise a plurality of upper corrugating rollers positioned to engage a top side of the extruded sheet and a plurality of lower corrugating rollers positioned to engage a bottom side of the extruded sheet. The upper corrugating rollers and the lower corrugating rollers each may be arranged in a delta configuration where the apex of each delta is positioned upstream from the remaining portions of each delta. Further, the upper corrugating rollers may be aligned along a series of upper linear paths and the lower corrugating rollers may be aligned along a series of lower linear paths. These linear paths may be arranged such that the upper linear paths and the lower linear paths alternate in sequence laterally across the corrugating roller region.
