Abstract

This disclosure teaches a helically corrugated two-layer tube made of strips of sheetmetal or plastic and this disclosure teaches further an apparatus and a method for manufacture of the tube. A leading and a lagging margin of an inner strip are folded over each other along the path of the helix. A leading margin of an outer strip overlaps a lagging margin thereof along a corrugation. That corrugation is pressed along with a mating corrugation of the inner strip to form a head-shaped or snap-button-shaped fold whereby the inner and outer strips are united.
