Abstract

An industrial traffic curtain can be formed of a plurality of overlapping strips suspended contiguously to each other from a hanger fixed adjacent to a top margin of the opening. Each strip is of a flexible transparent material of substantially uniform longitudinal character having a lateral cross-section defined by an alternating series of thicker portions separated from each other by thinner portions, the thicker and thinner portions having approximately the same width, the thinner and thicker portions being united by narrower tapered regions of changing thickness. The traffic curtain thus formed exhibits a surprisingly lower electrostatic attraction between the strips so that the resistance to separation from each other as goods and transporting vehicles attempt to pass through the curtain is much lower than prior art curtains.
