ABSTRACT:
A longitudinally reinforced crimped streamer includes a thin narrow metallic strip of flexible streamer material having a pair of opposite faces and a multiplicity of longitudinally-spaced, transversely-extending crimps set therein. The crimps form a series of alternating, opposite-facing, permanent, flexible bends in the streamer material and provide a multiplicity of transversely-extending opposing pairs of surfaces with the surfaces of one pair being disposed in inclined relation to the surfaces of each adjacent pair. The streamer also includes at least one elongated strip of flexible reinforcing material much narrower in width than the strip of streamer material and adhesively applied to adjacent surfaces provided on one face of the streamer material strip and extending longitudinally therealong, generally perpendicular to the extent of the crimps and centered between opposite side edges of the streamer material strip. The reinforcing material strip can be in the form of ordinary flexible strapping tape.
