Abstract
A corrugated plastic panel is produced by providing a plastic panel corrugation device whereby a plastic material is extruded, a cooled extrusion is formed by passing the extrusion through a cooling roller assembly, a corrugated extrusion is formed by passing the cooled extrusion through a forming roller assembly when the cooled extrusion has reached its impressionable temperature range, a corrugated extrusion is passed through a pulling roller assembly when the corrugated extrusion has reached its hardening temperature range, and a corrugated plastic panel is formed by passing the corrugated extrusion through an extrusion cutting assembly.
