In the course of a pipe train, the installation of an apparatus (10) for cooling a manufactured glass rod (15) is proposed. The device (10) has at least two cooling chambers (16) arranged along the glass strand (15) for sectional cooling of the glass strand (15). A gaseous cooling medium (K) is either blown into the cooling chamber (16) or sucked out of the cooling chambers (16). The glass strand (15) is passed through each cooling chamber (16), with an aperture (14) provided at each of the pass-through points, whose opening (17) is larger than the cross-section or diameter of the glass strand (15). As a result, an annular gap forms between the opening (17) and the surface of the glass strand (15), so that a turbulent flow (S) of the gaseous cooling medium (K) is generated, which enables a high cooling rate.
