Device and method for conveying a glass tube or glass rod strand with a cross-section deviating from a circular form

In an apparatus for conveying a glass tube strand or glass rod strand having a cross-section that is different from a circular cross-section, in particular having an oval cross-section, a plurality of support and guide members are arranged, if viewed in the direction of movement of the glass tube strand or glass rod strand, one after the other such that the moving glass tube strand or glass rod strand is directly supported thereon and guided by them. The support and guide members are disposed tilted in said direction of movement so that the moving glass tube strand or glass rod strand is directly supported on edges of the support and guide members. Thus, one-sided heat losses due to heat dissipation via the support and guide members can be significantly reduced to thereby reduce the curvature of the glass tube strand or glass rod strand.
