A tubular spacer core ( 50 ) may be used to manufacture an insulated glass assembly. The core is hollow and has a plurality of bending zones along its length. Each bending zone includes a plurality of circumferential ribs ( 53 ). Each rib has sides ( 57, 59 ) of unequal length. The ribs reenter and overlap their adjacent ribs when the core is bent along the longitudinal axis of the core. The ribs ( 53 ) lock in place to form a sharp corner at the inner edge ( 52 ), at the bend. The ribs ( 53 ) unfold and expand at the outer edge ( 54 ), at the location of the bend. The core ( 50 ) may also include a layer of desiccant and a vapor barrier. Adhesive is used to secure the appropriately shaped core between a pair of opposing glass plates, to manufacture an insulated glass assembly. |
