Abstract

A method and device for manufacturing optical transmission elements which contains a SZ-stranded bundle of several optical waveguides received in a tubular jacket characterized by stranding the waveguides into the bundle while they are moving in a vertical direction, applying a filling material to the waveguides adjacent a stranding point to prevent the unstranding of the bundle until at least the tubular jacket has been applied. Preferably, the application of the jacket is by extruding the jacket onto the bundle and the method can include the application of an additional filling material to complete the filling of the jacket.
