flat knitting machine, high production and with limited overall dimensions in plan, for the thermoforming blow molding of containers or other hollow bodies and in thermoplastic material.

摘要

Straight-line machine for blow molding thermoforming of containers or other hollow bodies and in thermoplastic material, of the type that includes at least one extruder (E) which feeds at least one extrusion head (T1) of several side-by-side parisons (Z), placed on an ideal vertical plane parallel to or coinciding with the ideal plane which contains the longitudinal axis of the same extruder, which comprises below said head (T1) and at its service, a pair of mold and counter-mold groups (S1, S2) with relative grippers (P1, P2) alternately movable along an axis contained in the vertical ideal plane of the same extrusion head (T1), which comprises means for transferring the containers cyclically produced by the molds onto a single conveyor (B3) placed laterally to the path of the groups mold and counter-mold, characterized in that this conveyor (B3) is placed longitudinally below said extruder (E), to limit the overall dimensions of the machine ina and that the same mold and counter-mold groups are movable on a horizontal path and that in phase with such movement there operate means for lifting and lowering cyclically the extruder (E) and / or said extrusion head (T1) or a part of this, to avoid interferences of the produced parisons, both between them and with the molds when these come out closed by the cooperation with the same extrusion head (T1).
