    摘要： A mold apparatus and method for forming a shaped laminate in one step are provided where the laminate includes a cladding layer and a foam backing layer. The apparatus includes a male mold half matable to a female mold half that define a mold cavity. An inlet is mounted on the mold apparatus for introducing foamable materials into the mold cavity. Edge folding members, carried by one of the mold halves, movable from a retracted position to an extended position, fold the cladding layer over at least part of the edge of the foam backing layer. Trim blades are located adjacent to the edge folding members movable from a retracted position adjacent the cavity to an extended position engaging the other mold half to sever the cladding layer to define the finished shape of the laminate.

    摘要： An apparatus and method for making a wide angle light diffusing lens of the type which includes a peripherally extending lip for supporting the lens in a downwardly opening light fixture. The lens includes a downwardly and inwardly converging light translucent side walls as well as downwardly and inwardly extending end walls and which are connected together. These walls effectively form a prismatically shaped lens which permits dispersion of light from planes at a wide angle. The apparatus of the invention includes a form or mold having an upwardly extending rib on its upper surface which generally defines a lower edge of the lens and aids in defining the other edges of the prismatically shaped lens. A plastic sheet as, for example, an acrylic plastic sheet, is heated to a temperature where it softens and is somewhat flowable, moldable and bendable and which is then draped over the rib on the mold. A mold top is then disposed over the mold encapsulating the plastic sheet therein. When the sheet is cooled, it will assume the form of the wide angle light diffusing lens.

    摘要： A method for the shaping of a sheet of preform material. A flat planar (heated) sheet of preform material is held tightly between two elastomeric sheets, the sheets and preform material forming a laminate assembly. The laminate assembly is then formed about a mold having the desired contours. The elastomeric sheets maintain the preform material parallel to the surface contours of the mold as the molding process proceeds. A fluid such as air is flowed between the mold surface and the laminate assembly during the forming process to prevent the elastomeric sheets from binding on the mold surface. Wrinkles are eliminated in the final shape of the preform material, and fiber distortion of tears or rips in the material are minimized due to the fluid lubrication between the mold surface and the laminate assembly.

    摘要： Polymerized foam material in flat billet form is enclosed in a heat-retaining envelope and heated to forming temperature then promptly loaded into an innovative unheated forming press and accurately formed before cooling below forming temperature. The heat-retaining envelope has an expansive skin on one side and a contractive skin on the other side to facilitate bending without wrinkling or other distortion. The forming press utilizes a rigid male form punch and a spring-tensioned elastic belt, supported on a pair of variably-spaced rollers, initially presenting a flat compliant surface upon which the heated workpiece is placed. Pressure from the form punch progressively deflects the workpiece and the belt, which becomes a compliant mold member conforming itself and the workpiece progressively around the form punch to yield an article of required carved shape, free of wrinkles or tool creep distortions.
