Abstract
In a transport device for elongated substrates, especially in hot processes, which includes an essentially rectangular frame, formed by longitudinal and transverse spars connected to each other, in which at least three transverse spars are provided between two longitudinal spars, at least one transverse spar is made from a material, whose heat expansion coefficient differs from the heat expansion coefficient of the material of the other transverse spars or/and at least one transverse spar is connected force-free to at least one transverse support or/and at least one transverse spar is formed from an open profile.
