Abstract
The arrangement comprises a carrier (1) having fibre-guiding grooves (2), which carrier is made of glass-like carbon. In the manufacture of the carrier the fibre-guiding grooves are formed in a cured phenol-resin body preferably by means of an extrusion die whose shape corresponds to that of the fibre-guiding grooves to be formed. The phenol-resin body thus formed is converted into the glass-like carbon carrier by carbonization.
