Abstract
Hollow articles of thermoplastic synthetic resin are produced by suction-blowing in an apparatus in which the shaping is decoupled from the extrusion. A preform handler, especially a six-axis robot, engages the preform at the extrusion or coextrusion head and carries it to the closed mold into which the preform is sucked by suction generated in the mold cavity. While shaping is effected in the mold, extrusion can continue at the head to form a further preform.
