Abstract: An apparatus for producing plastic containers with a heating device configured to heat plastic preforms and with a forming device which forms the heated plastic preforms into plastic containers, wherein this forming device being arranged downstream of the heating device in the transport direction of the plastic preforms, and wherein the heating device and/or the forming device having at least one regulating device which makes it possible to regulate the heating process and/or the forming process as a function of at least one property of the plastic preforms. According to the invention, the at least one control device for controlling takes into account in advance at least one variable value which influences the heating process and/or the forming process.

Abstract: Disclosed is a method analysing plastic preforms, wherein plastic preforms are transported along a predetermined transport path by a transport device and an infrared absorption coefficient is determined in at least one region of the plastic preform, wherein, in order to determine the infrared absorption coefficient of the plastic preform, infrared radiation is applied to the plastic preform by a first radiation device and radiation passing through the plastic preform is received by at least one receiving device and an infrared absorption behaviour of the plastic preform is determined from this received radiation, wherein the radiation device acts upon the plastic preforms with infrared radiation in a predetermined wavelength range and an evaluation device evaluates the radiation as a function of its wavelength in a wavelength range from 1500 nm to 2000 nm.
