ABSTRACT:
Method for compression molding plastic articles. The method includes the step of providing a plurality of molds mounted for travel around a first axis. Each mold includes upper and lower mold sections, with at least one of the 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 is provided to deliver 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. At least one of the mold sections is moved radially relative to the first axis during at least a portion of the first endless path wherein the second endless path overlies the first endless path.
