Abstract

A method of forming a foamed plastic sheet or tube in which the foamable plastic material in a deformable condition is extruded through a hole in an extrusion head formed with grooves or recesses such that the sheet or tube of extruded plastic that out of the orifice has local, spaced, superficial elevations, the shape, spacing and dimensions of said grooves or recesses being such that the extruded sheet or tube does not wrinkle spontaneously or does not significantly.
