Abstract

Moulding machine has continuous opposed parallel belts carrying female moulds, and pipe is fed between them. Spiral ribs are formed on tube by interaction of the ribbed profiles on mould surfaces with the tube surface a ram with ribbed mandrel being used to support tube and air rib forming.
