Abstract

An endless strip of plastic with a core consisting of a material with greater rigidity is extruded and wound in a hot state onto a pair of mandrels in a helical convolution with oval cross-section. The adjacent convolutions are joined and moved along the mandrels in an axial direction to form an endless hose with oval cross-section, after which the hose is moved forwards over the ends of the mandrels while it is still sufficiently soft to assume a circular cross-section.
