Abstract: An article support such as a shelf or a table top has a frame that, in its heated state, slidably receives a glass or plastic planar sheet into grooves along two opposing edges of the frame, until an end of the sheet abuts a third edge of the frame that joins the two opposing edges. The edges of the frame have lips that rest on a portion of the top surface of the sheet. When cooled, the frame contracts such that the edges of the sheet are tightly engaged within the grooves of the frame and the lips tightly abut the top surface of the sheet, thereby creating an article support that resists spills around its periphery. The frame may be reheated to expand the material of the frame, permitting removal of the sheet from the frame. Thus, the frame and the sheet may be recycled.

Abstract: A method of compression moulding an article from rubber moulding material incorporating hollow inserts avoids damage to the inserts. Where compression moulding takes place in an enclosed mould at an elevated pressure, the pressure can distort and damage the hollow inserts especially if they are of plastics. In order to avoid such distortion and damage, the method compresses during moulding creating a pressure in a cavity of the insert which substantially balances the pressure exerted on the exterior of the insert by the rubber moulding material in the mould. The pressure in the cavity is preferably produced by introducing some rubber moulding material into the cavity of the insert. This material becomes pressurized during moulding and supports the interior of the insert.
