Abstract:
An apparatus for producing hollow articles of thermoplastic synthetic resin by suction-blowing, comprising:an extrusion head connected to at least one extruder for extruding a tubular blow-moldable thermoplastic synthetic resin preform; a mold spaced from said head and having a mold cavity adapted to receive said tubular preform, a slider being displaceable across said mold cavity at least at a bottom of the mold cavity; means connected with said mold for drawing a suction in said mold cavity at a lower portion thereof; a preform handler positioned to grip a preform extruded by said head for transferring the preform to said cavity for shaping into an article whereby the shaping of preforms into articles is decoupled from the extrusion of preforms and simultaneously with the shaping of the preforms, tubular preforms are continuously or discontinuously extruded at said head; and a blowing piercer for penetrating and blowing said preform.
