Abstract

See full text

A material for use in an industrial traffic curtain formed of a flexible transparent material, such as polyvinyl chloride, having a substantially uniform longitudinal cross-section, which can be achieved by way of a conventional extrusion process. The strip of material has a transverse cross-section defined by first and second parallel surfaces, the surfaces having an array of regularly spaced, generally rectangular longitudinal ribs of predetermined height and width. The ribs on the first surface are arranged to be coincident with the ribs on the second surface. Each adjacent pair of ribs on each of the surfaces is interspersed by a linear bead having a height dimension approximating the height dimension of the adjacent pair of ribs. The linear beads have a width dimension less than about 10% of the distance between the adjacent pair of ribs so that the space between each pair of ribs remains substantially transparent and vision through the strip is unimpeded. The overlapping strips are arranged in the curtain so that distal surfaces of the ribs on confronting portions of the overlapping strips are in contact with each other.
