Abstract

A starting material for tubes, esp. for protecting sheathing of underground cables or for land drains, comprises a band of adequately hard material, pref. hard plastics; the band is supplied rolled up and, to make a given length of tube, that length of band is unrolled and folded up as a cylinder about its longitudinal axis, then joined at the edges to constitute a longitudinal seam.
