  • Patent number: 10071517
    Abstract: A polymer filter assembly through which flowable material from a supply is directed for processing before passing to a die assembly through which the flowable material is delivered to form a sheet layer. The polymer filter assembly has a polymer filter frame that supports processing components for the flowable material and a support assembly for the polymer filter frame. The support assembly includes components cooperating between the polymer filter frame and a base upon which the polymer filter frame is supported to allow controlled relative vertical movement between the polymer filter frame and base to thereby permit controlled alignment between the polymer filter frame and at least one of: a) an upstream component that delivers flowable material from the supply; and b) the die assembly.

  • Patent number: 10040175
    Abstract: A film-like member is supported in a flat shape by vacuum suction. A plurality of lift pins are arranged in a planar configuration and bear a film-like member placed on their upper ends. Tubular pads made of rubber for holding the film-like member by vacuum suction are attached to upper portions of the lift pins. The height of the lift pins can be adjusted by a screw fastening mechanism. The deformation of the film-like member can be corrected to a flat or concavely curved shape by suction from the pads. When the correction cannot be achieved by suction alone, the correction may be supplemented by ejection of air from a nozzle.

  • Patent number: 9931769
    Abstract: Molded rubber objects may be molded and de-molded by defining both a desired final form for the molded rubber object and a tab extending from the final form of the molded rubber object using a cavity in a mold. Rubber pellets may be dispensed in predetermined amounts at desired location(s) within the cavity to provide the rubber needed to form the molded rubber object. Heat and pressure may be applied to the mold to cause the rubber pellets to fill the cavity defining both the desired final form of the molded rubber object and the tab. After the heat and pressure has been applied, a gripping device may grasp the tab and move the tab in a direction and with sufficient force to peel the rubber object from the mold cavity. If desired, the tab may be removed from the molded rubber object.
