  • Patent number: 6389769
    Abstract: A door and method for fabrication of unitary six panel steel doors wherein frames members (stiles and rails or headers) are fabricated by forming metal stock into a cross-sectional channel configuration, cutting and swaging the channels into predetermined lengths. The stiles and rails of the frame members are swaged to provide frictional interconnection at the corners thereof upon assembly of the frame members (stiles and rails) into a rectangular frame configuration. Assembly of the frame is accomplished in a shuttle having two assembly jigs. Upon assembly, each frame is moved by the shuttle into a molding press wherein a panel of foam is molded within the frame. The shuttle moves back and forth through the molding press in a manner which provides for removal of a completed panel and assembly of an additional frame from one jig of the shuttle while the molding operation is accomplished within the molding press upon a frame retained within the other jig of the shuttle.

  • Patent number: 5094903
    Abstract: A hanger which includes two depending strips of resilient material interconnected at their upper margins by a flexible link which enables the hanger at its link to be placed over the upper marinal edge of a sheet of material with the strips straddling of the sheet material and thus acting as a spacer preventing contact between adjacent sheets of material stacked in an upright orientation.

  • Patent number: 4927023
    Abstract: A spacer member is adhered to a tape having adhesives at opposite faces thereof and a release layer is adhered to the first named tape to releasably connect multiple spacer members and expose adhesive at one face for adhering a spacer member to a fragile object upon removal of the release layer. The method includes forming spacer members of selected size from a large foam panel. One face of an adhesively coated tape is adhered to the panel and a release layer is adhered to the opposite face of the tape web, after which spacer members of selected size and shape are formed by cutting through the panel and the tape web without severing the release layer.
