Abstract
Apparatus for compression molding plastic articles includes a plurality of molds mounted for travel around a first axis. Each mold includes an upper mold section and a lower mold section, with at least one of the upper and lower mold sections being moveable in a non-circular first endless path, and being moveable with respect to the other mold section to form a mold cavity. A mold charge delivery system delivers individual mold charges to the mold cavities and includes at least one delivery mechanism that travels in a second endless path around a second axis spaced from the first axis, wherein the second endless path overlies a portion of the first endless path.
