Abstract
An air bladder is formed by producing a foil imprint on an inner surface of a first uncured rubber sheet, by heat pressing the imprint from a hot roll leaf stamping tape to the sheet. The first sheet is delivered from a reel to the heat press via a driven roller and idler roller combination. The hot roll leaf stamping tape is delivered above the first sheet via a take up reel and idler roller combination. The heating press includes a heated platen having the contour of the desired imprint, such that the imprint takes on the shape of the heated platen. A second sheet of uncured rubber is laminated to the first sheet, with the second sheet laminated over the first sheet, thereby convering the imprint. The two sheets are vulcanized which cures the non-imprinted surfaces of the rubber sheets together, thereby forming an air pocket in the shape of the imprint between the two sheets.
