Shaping Of Tube Ends By Bending Or Straightening
(AREA)
Abstract
Improved tube, characterized by consisting of a tubular bore, of flexible material, extruded in undefined lengths and provided with walls of relatively reduced thickness, on whose outer surface, essentially, at least one continuous continuous profile is helically wound, with its successive separate turns, which is joined to said tubular bore along its entire length.

Extensible helical flex, e.g. for supplying power to electric shaver - has polyamide filament co-extruded with the conductors inside a PVC casing to facilitate return to contracted position
