  • a first pretreatment module can be designed as a flame pyrolysis device, whereas a second pretreatment module comprises a plasma nozzle. In this way, the different pretreatment modules can be positioned and used as appropriate.
  • each pretreatment module is assigned a group of adjustment modules 310, 320 and 330, which enable the position of the respective pretreatment module to be set completely independently of the setting of the position of the respective other pretreatment module.
  • the position of the pretreatment module 301 can thus be set completely independently of the position of the pretreatment module 302 with the aid of the adjustment module 310.
  • an adjustment module also includes a number of two or more adjustment modules or adjustment units (which can then each cause a movement of the pretreatment unit or the pretreatment module along a translational or rotational degree of freedom), such as these, for example, with reference to Fig. 2 can be understood in summary.
  • the already mentioned end stops can be used to advantage in order to avoid a collision of the pre-treatment modules with each other or with the transport device for the containers (see Fig Fig. 1 ) to prevent.
  • the setting of the position of the pretreatment module by the individual adjustment modules can take place either automatically or manually by using appropriately operated drive means (that is to say manually or automatically operated).
  • the automatically operated drive means include all drive means which adjust the position without direct interaction with an operator and here in particular without physical effort on the part of the operator to adjust the position of the pretreatment module. These include, for example, servomotors or spindle-nut drives that are driven by electrical power.
  • the manual drive means provided as an alternative to this are, for example, handwheels which, for example, also enable the position of the pretreatment modules to be set via a spindle-nut construction.
  • the setting of the position can be implemented in a reproducible manner by a suitable electronic control, which can also have a feedback circuit for checking and, if necessary, correcting a set position.
  • a suitable electronic control which can also have a feedback circuit for checking and, if necessary, correcting a set position.
  • the controls commonly provided for servomotors can accomplish this.
  • a counter is provided at the same time.
  • This counter can either function completely analog (that is, without electricity) or it can be designed as an electronic display, for example in the form of a digital display.
  • the counter is always provided in such a way that it can display a value that is indicative of the position of the pretreatment module. This can consist, for example, of an angle of inclination or a relative height value or a horizontal value measured in relation to an initial position. It can be determined, for example, as a function of the number of revolutions of the hand crank or as a function of a value measured with the aid of a sensor.
  • Inclination sensors or height sensors can be used here.
  • the accuracy of the counter is so high that the operator, even if the manual drive means is operated multiple times, a reproducible setting of the position (possibly except for one metrological inaccuracy of, for example, a few millimeters or a few micrometers) is made possible.
