Abstract

Corrugated thermoplastic tubing is produced with a housing contg. an extrusion head and ring nozzle and a pointed tool with leading end to divide the polymer and trailing end to act as feed; the pointed tool is attached in the housing by a cruciform pressure device, a central tube is coaxially fixed to the feed point and has a tapered seal at its trailing end; two series of shaping tools arranged as endless belts corrugate the tubing by internal air pressure applied towards their moulding surfaces, the air space being confined between the extrusion nozzle and the seal. The extrusion head has a wire feed hole at the first end of the central tube so that wire enters this tube and emerges beyond the moulding point and the seal; the air to mould the corrugations passes via another hole to the pointed tool, round the central tube to its first end and thence to the outlet of the extruder head, where it emerges through an outlet between the feed point and the outside of the tubing. Simple construction enables wire to move together with the extruded material, suitable for small dia. tubing.
