  • Patent number: 4518558
    Abstract: A method and apparatus for producing hollow plastic articles are disclosed. The articles have a blow-molded portion and a compression-molded portion, and are formed by downwardly extruding plastic at at least one extrusion rate to progressively form a parison having a downwardly facing open end from a first location adjacent an extrusion head toward a second location axially spaced therefrom. A male mold member is provided at the second location. Portions of the open end of the parison are engaged by a plurality of fingers, while the open end travels toward the second location and the engaged portions are moved downwardly at a rate at least corresponding to the extrusion rate. During the travel toward the second location, portions of the open end are radially expanded and guided over the male mold member.
