A position, calibration and cooling roll is positioned proximate to the second smoothing roll. The position, calibration and cooling roll is movable relative to the second smoothing roll. A first fixed calibration and cooling roll is positioned proximate the position, calibration and cooling roll. The first fixed calibration and cooling roll is in a fixed position relative to the second smoothing roll. A first movable calibration and cooling roll is positioned proximate the first fixed calibration and cooling roll The first movable calibration and cooling roll is movable relative to the first fixed calibration and cooling roll. Actuators cooperate with the position, calibration and cooling roll and the first movable cooling roll to provide both nip pressure and gap control.

A rotary trimmer for trimming flash and the blow dome from a plastic bottle forming a portion of a plastic blow molded log discharged from a blow mold includes flash punching, a neck support plate, and a guillotine blade. The neck support plate is movable by a plate drive to move adjacent the neck of the plastic log to support the neck during cutting of the blow dome and cooperates with a log holder to essentially support the entire outer periphery of the neck. The guillotine blade is movable by a blade drive to pass through the plastic log and sever the blow dome from the neck of the log.

A multiple-piece cam (210, 230, 212, 220, 234) unit for use in a molding machine. The cam unit has a cam track which engages cam followers of mold assemblies of the molding machine to move the cam followers between a first position and a second position. The cam unit includes a first cam section (210) and a second cam section (230). The first cam section has an entrance portion (212) which is dimensioned to receive the cam followers therein. The second cam section has an exit portion (234) positioned to release the cam followers therefrom. The second cam section is moveably mounted to the molding machine to allow the exit portion of the second cam section to be moved relative to the entrance portion of the first cam section, to insure that the cam followers exiting the exit portion of the second cam section are properly aligned to enter the entrance portion of the first cam section.

An adjustable platen assembly (126) and method of assembly therefore. The platen assembly has a platen and a pressure plate (212) attached to the platen. The pressure plate may be rotatable around a longitudinal axis of the rod according to the size of a mold half mounted to the platen. The platen assembly may have at least one platen support (246) mounted to the platen. The at least one platen support may be rotatably mounted to the mold clamp. The at least one platen support can be rotated according to the size of a mold half mounted to the platen. The adjustable platen provides support to the mold half to reduce the amount of deformation to the mold half that is caused by the application of a closing force.

The invention is directed a rotary molding machine (20) having a wheel mounted for rotation on a pair of shafts positioned along the rotational axis of the wheel. A first shaft cooperates with a first turntable of the wheel and a second shaft cooperates with a second turntable. The first and second turntables extend transversely to the rotational axis. A plurality of modular mold clamp assemblies (100) are positioned on the wheel, with each modular mold clamp assembly being moveable between an open and a closed position. Each modular mold clamp assembly has mounting areas which are mounted with respective mounting locations each turntable. The modular mold clamp assemblies provide the structure and rigidity between the turntables to help maintain the turntables in position relative to each other.

A modular mold clamp assembly for use in a molding machine. The assembly has a frame with a base member (112) and oppositely- facing end members (111, 113), with the oppositely- facing end members having mounting areas provided thereon. First and second platens (132, 134) are movably mounted on the base member between an open and a closed position. The platens are mounted on the frame and are movable relative to the frame without transmitting forces to the frame. The frame, containing the platens, can be mounted or unmounted to the molding machine by the use of mounting hardware cooperating with the mounting area of the frame.
