Abstract
A tube is disclosed having alternating relatively rigid and relatively flexible segments formed along its length. The tube wall is formed of overlapping wrappings of a continuous web of thermoplastic material. The thickness of the web is varied to form the rigid and flexible segments. A reinforcing strand of metal or plastic wire is helically coiled along with the web. A
method and apparatus are disclosed in which the web is taken up around helically skewed forming rollers. The speed of rotation of the forming rollers or the rate of extrusion of the web is varied to produce the rigid and flexible segments. The reinforcing strand may be a thermoplastic wire formed by extrusion simultaneously with the formation of the tube.
