  • the subject of the invention can also be marked by the secondary classifying symbol of B29 C49/08 which refers to stretching along two axes during the blowing of preforms.
  • the technical problem that has been solved by this invention comprises the question of how to construct an automatic machine for the manufacture of PET bottles of various dimensions and shapes by blowing of preforms of various weights, so that, in comparison with the available automatic machines of similar capacity, its power consumption is decreased for 50 %, that blowing of bottles is performed with air under relatively low pressure, that it has remarkably smaller dimensions and relatively large production capacity and that it operates safely having a long working life.
  • the single-stage system includes all technical operations beginning with loading of preforms, their heating, blowing of preforms in a blowing mould, and ejection of finished bottles, all of them being performed at the same machine.
  • the two-stage system comprises two machines, one for manufacturing of preforms in the shape of test tubes, and the other for performing the blowing of preforms in a movable blowing mould in which bottles of various shapes and dimensions are obtained.

  • Preforms in the form of polyethylene test tubes are cylinders with semispherical closed bottoms and open threaded necks obtained by extrusion.
