1. A method for detaching a workpiece from an adhesive fastening element, the adhesive fastening element comprising:
an outer member; and a consumable inner member disposed inside the outer member and releasably movable relative to the outer member along a longitudinal axis of the adhesive fastening element; wherein a bond is formed by an adhesive between the workpiece and a bonding surface of the consumable inner member of the adhesive fastening element; the method comprising: providing the consumable inner member within the outer member; locking the position of the consumable inner member relative to the outer member; subsequently applying the adhesive to the bonding surface of the consumable inner member and forming a bond between the adhesive and the workpiece; releasing the consumable inner member and moving the consumable inner member such that the workpiece is moved away from the outer member prior to detaching the workpiece from the adhesive fastening element; detaching the workpiece from the adhesive fastening element with the bonding surface attached to the workpiece; and replacing the bonding surface with another bonding surface for subsequent use.
