  • Patent number: 4300296
    Abstract: In an ironing press the heating plate is suspended in a pivotal manner on the arm of the press by the intermediary of two sliders each engaged in a bore of the arm. The lower end of each slider presents a diammetrical hole engaged with a stirrup, mounted on a profile or section solid with the heating plate.Thus, when the heating plate is lowered onto the ironing board, it can adapt its position with respect to this latter, taking into account the differences in thickness of the article to be ironed.

  • Patent number: 3962012
    Abstract: Improved process for laminating two sheets, the surface of the primary sheet being sensitive to distortion by pressure or friction, by applying an adhesive to the back side of the primary sheet or to the mating side of the secondary sheet, or to both, contacting the mating side of the secondary sheet with the back side of the primary sheet and firmly pressing together the two sheets while avoiding the application of any pressure to the pressure-sensitive face side of the primary sheet until at least 50 percent of the terminal bond strength is developed, by maintaining the primary and secondary sheets taut and applying pressure from the back side of the secondary sheet. Laminates prepared according to the above process, such as tufted carpets comprising a primary backing material stitched with closely spaced tufts of yarn and a secondary backing material adhered thereto with an adhesive, have improved pile lay characteristics.
