Abstract
A device is disclosed for applying individual reinforcing threads onto a tubular layer. The device contains a positioning ring with equidistant holes that lie on a circumferential line, with the positioning ring surrounding and concentric with a rotationally symmetric, funnel-shaped deflection element. The deflection element deflects the reinforcing threads that are guided from radially outward to radially inward through the holes f the positioning ring into an essentially axial direction, wherein all the threads assume an equidistant spacing from one another. Also disclosed is a process for manufacturing an unfinished tube consisting of several layers with the aid of the device.
