ABSTRACT:
The compact apparatus for the molding of hollow containers in molecularly orientable plastic material has a plurality of units for forming the containers and a discharge unit for the formed containers. The units are aligned at least in a row, there being present a conveyor device adapted for linking the units. The conveyor device has a plurality of carriages having support jaws for the containers during the forming phase and being slidable on rectilinear guides along a first path linking the aligned units, and a second path parallel to same, linking the remaining unit or units. A translator moves the carriages from one of the parallel paths to the other at their relative ends. A step-feed actuator shifts the carriages along the first path, bringing the carriages holding the containers during the molding phase from one unit to the next of the aligned units. A transfer actuator displaces the carriages along the second path. The conveyor device defines a closed circuit, linking together the molding and discharge units.
