The invention relates to a method of blowing a line (1) into an empty sheath (13) in which the line (1) is unreeled from a storage roll and is transported in the empty sheath (13) by means of compressed air blown into the empty sheath (13). An undisturbed unreeling of the line from the roll is made possible also at very high unreeling speeds in that the storage roll is a self-supporting criss-crossed roll (4) having no coil former and contains a line comprising a sheath which envelops a LWG or an electrical conductor which sheath when wound in the criss-crossed roll comprises a flattened cross-sectional contour which is widened in the direction of the winding plane.

Method of blowing a line into an empty sheath

The invention relates to a roll manufactured with a light waveguide conductor (LWG-conductor), in particular for the transmission of optical signals from and to, respectively, a moving body. A perfect winding construction from which the conductor can be unreeled without interference is obtained in that the LWG-conductor (1) is wound to form a self-supporting cross-roll without a winding core.
