One or more sheets, e. g. two glass sheets heated to their deformation temperature are shaped by positioning the sheets on a sheet supporting surface of an outline mold. The outline mold and press face of a shaping member are moved relative to one another to bias the marginal edge portions of the upper sheet against the press face to establish an enclosure around the peripheral edges of the sheets. Vacuum is applied to the peripheral edges of the sheets to pull the air from between the sheets, and from between the press face and adjacent sheet surface as positive or atmospheric pressure is applied to bottom sheet to move the sheets against the press face. Optionally a vacuum can be pulled through passageways in the press face during the shaping of the sheets and pressurized air moved through the passageways after the sheets are shaped to move the sheets away from the press face.

A mounting assembly comprises a mounting member comprising a base having a first surface; a central portion extending from the base and having a second surface spaced from the base; and a shoulder region located between the base and the central portion. The area of the first surface may be different from the area of the second surface. The shoulder region of the mounting member can include a wall extending from at least in close proximity to the second surface of the central portion to the base. In a nonlimiting embodiment of the assembly, the base is cylindrically shaped with a substantially flat first surface, the second surface of the central portion is substantially flat and substantially circular in plan view and further is concentric with the first surface, and the wall extends from the second surface to a location inboard of the periphery of the base.

A flat elongated substrate having a bead of a gas and/or moisture pervious adhesive having a desiccant is moved along a predetermined linear path between spaced upper wheels aligned with spaced lower wheels. The upper wheels have a peripheral groove to shape the bead as the substrate moves between the upper and lower wheels. The lower wheels each have a U shape peripheral groove with the base of the U of the downstream wheels being narrower than the base of the U of the upstream wheels and the depth of the U of the downstream wheels being deeper than the depth of the U of the upstream wheels to provide a spacer stock having a base connected to a pair of spaced upright legs such that the base connected to the legs have a generally U shape configuration and a shaped bead on the surface of the base between the legs. The spacer stock may be bent to form a spacer frame to separate outer sheets of an insulating glazing unit.

The present invention provides a spacer frame for making a multi-sheet unit. The frame includes a spacer stock member having a first end and a second end, and a corner key comprising a bendable elongated body having a first end in the first end of the spacer stock member, an opposite second end in the second end of the spacer stock member, and a cut out between the ends, the ends of the corner key bendable relative to one another to decrease the spacing of the cut out.

The present invention provides spacer stock for making a spacer frame for a multi-sheet unit. The spacer stock includes a first supporting surface; a second supporting surface opposite to, and facing away from, the first supporting surface; a base surface between and connecting the first and second supporting surfaces, and wherein the first and second supporting surfaces and base surface are made of plastic and rate of moisture and/or gas movement through portions of the first and second supporting surfaces is greater than the rate of moisture and/or gas movement, respectively through the base surface.

A glass sheet is cut while at a temperature at about its annealing point temperature by scoring the glass sheet along a line of cut and imparting a bending moment to the glass along the scored line to open the glass. The glass sheet remains at its elevated temperature throughout the cutting operation to reduce or eliminate additional heating required for subsequent processing.
