Abstract
A corrugated cylindrical filter element is provided having an external spiral tape support, comprising a corrugated filter sheet material in the form of a cylinder having an end cap at each end of the cylinder sealingly bonded to the filter sheet material at that end, the corrugations of the filter sheet material having a tendency to become distorted and displaced with respect to each other under the conditions to which the material is subjected in use, and a relatively narrow strip to continuous high-modulus fiber-reinforced synthetic plastic tape spirally wound around the cylinder, spanning the corrugations and extending between each end and bonded to the end cap and to the tips of the corrugations in a manner to prevent distortion and displacement thereof.
