  • Patent number: 8905104
    Abstract: An adhesive fastening element (602) for holding a workpiece (608), the adhesive fastening element (602) comprising: a body (604, 606) defining a recess (642) for receiving a protrusion (644) of the workpiece (608); wherein, in use, adhesive is applied between an end surface of the recess (642) and an end surface of the protrusion (644) and between a side surface of the recess (642) and a side surface of the protrusion (644) to bond the workpiece (608) to the adhesive fastening element (602). The workpiece (608) may be aligned with a reference point on the adhesive fastening element (602) and the adhesive cured to fix the position of the workpiece (608) relative to the adhesive fastening element (602).

  • Patent number: 8900394
    Abstract: An adhesive fastening element (802) for holding a workpiece (808), the adhesive fastening element (802) comprising: an outer member (804); and a consumable inner member (806) disposed inside the outer member (804) and releasably movable relative to the outer member (804) along a longitudinal axis of the adhesive fastening element (802); wherein the consumable inner member (806) comprises a bonding surface which, in use, is bonded by an adhesive (810) to the workpiece (808) and is removed and replaced to detach the workpiece (808) from the adhesive fastening element (802).

  • Patent number: 8821672
    Abstract: An adhesive fastening element includes a first member and a second member adjacent to the first member and movable relative to the first member along a longitudinal axis of the adhesive fastening element, wherein a bond is formed by an adhesive between the workpiece and the first and second members of the adhesive fastening element. A method for de- bonding a workpiece from an adhesive fastening element includes moving the second member away from the workpiece and breaks the bond between the second member and the workpiece and moving the first and second members such that the second member moves towards the workpiece and applies a force to the workpiece so as to break the bond between the first member and the workpiece, and lo de-bond the workpiece from the adhesive fastening element.
