ABSTRACT:
The invention relates to a method and an apparatus for the manufacture of high-pressure hose composed of a plastic core and a plurality of layers of helically wound plastic-resisting members formed in particular of plastic wires of high tensile strength which are rewound in a rewinding device from a supply reel onto several working spools, and optionally of an outer cover made of a plastic material. An intermediate layer of plastic yarn is disposed between every two helically wound pressure-resisting layers. After being unwound, the wires necessary for the helically wound pressure-resisting layers are precoiled over a hardened edge in the rewinding device and then wound onto the working spool in the stretched state. In accordance with the preferred embodiment, precoiling is done, not in a stranding machine, during hose production, but one stage earlier, in the rewinding device, where the individual wires are rewound from a supply reel onto so-called working spools.
