Summary:The present disclosure provides the installation of an apparatus for cooling a manufactured glass rod. The apparatus has at least two cooling chambers arranged along the glass strand for sectional cooling of the glass strand. A gaseous cooling medium is either blown into the cooling chamber or sucked out of the cooling chambers. The glass strand is passed through each cooling chamber, with an orifice provided at each of the pass-through points, whose opening is larger than the cross-section or diameter of the glass strand. As a result, an annular gap forms between the opening and the surface of the glass strand, so that a turbulent flow of the gaseous cooling medium is generated, which enables a high cooling rate.
