In a method for controlling the free deformation of thermoplastic material in an automated process for the further processing of the material to form articles, in particular in the production of ampoules, small bottles and the like from glass tubes, in which method, to obtain a high dimensional accuracy of the article, a correction action, via the effect of heat on the starting material in the heating phase, is carried out in dependence on a setpoint/actual-value comparison of the deformation, achieved in a predetermined working step, of a workpiece in the deformation region, the measurement of the deformation achieved, the setpoint/actual-value compari- son and the correction action are, in order to exclude interference influences in the development of the defor- mation, carried out in situ on one and the same workpiece during the development of the deformation in the heating phase.
