Abstract

A method for correction shape deviations in hard, hardened objects in which the objects are heated to a temperature which lies beneath the temperature at which the structure imparted to the objects during a preceding heating process (e.g. a temperature of ca 200 DEG C) is markedly affected, and then shape corrected. The invention also relates to an arrangement of apparatus, including an object conveyor and an object shape rectifying means, for carrying out the method.
