Abstract

Extruded sheet featuring ribs which intersect at intervals to form a hole bounded by a continuous rim formed from the intersecting ribs. Claims sheet made using coaxial rotary dies as used for netting but relieved to release a web between adjacent 'strands'. Pref. some groups of webs are relatively thick and define self-supporting segments if the tubular extrudate is slit longitudinally and spread out. Claimed for mfg. ribbed sheet from transparent materials, specif. polyethylene, offering the tear resistance or stiffness of a sheet approximately as thick as the total rib depth but using less material.
