Abstract: The present invention provides a method of manufacturing a vehicle cup holder arm, and a vehicle cup holder assembly produced thereby. The method includes injection molding a first material to form a base including an attachment feature adapted for engagement within an aperture adjacent a cup holder opening in a vehicle. A second material is injection molded to form an arm cup around the base and includes an arm. The second material does not chemically bond to the first material so that the arm cup and arm are rotatable with respect to the base for adjustably securing a cup in the cup holder opening. A third material is injection molded onto the arm to form a soft rubber grip for engaging a cup. The cup holder arm may be movable vertically for adjustment with respect to differently-sized cups.

Abstract: A positive displacement extruder for a viscous material, such as unvulcanized rubber, includes a feed member arranged in a chamber of a main body and driven for rotation so that the viscous material charged into the chamber is extruded from its outlet. A mouthpiece has an inlet that is spaced in a circumferential direction from the outlet of the main body and, in communication therewith, an extrusion nozzle. At least one cylinder device is rotatable about a center axis of the extruder so that the cylinder is alternately bought into communication with the outlet of the main body and the inlet of the mouthpiece. The viscous material is charged from the chamber of the main body into the cylinder device and discharged from the cylinder device into the mouthpiece, as the cylinder device is rotated about the center axis of the extruder and the piston of the cylinder device is driven by a cam device to reciprocate in the cylinder.

Abstract: A twin sheet thermoforming method and apparatus of a type using a rotary wheel to carry each of a series of clamping frames for releasably holding sheets to be formed through successive processing stations. The clamping frames can be shuttled on the wheel to be alternatively located for alignment with one of two forming tooling sets at a forming station, and to be shiftable at an unload-load station so that unloading and loading do not occur at the same location.
