Abstract: A scoring die matrix comprises an extruded strip having two portions, a matrix portion and a locator portion. The base of the matrix portion has a layer of adhesive applied thereto and a cover paper, preferably a silicone release paper, covering the adhesive. The region of the join between the locator portion and the matrix portion is partly cut through. The matrix is extruded in one piece and applied to the scoring press where the adhesive ensures that the matrix portion adheres thereto. The locator portion is then removed therefrom by pulling where it will tear away at the partly cut through weakened portions.
