<p>The device has a square shape stop (6) presented in a form of patched piece made up of rigid metal. The stop has a branch (7) installed in thickness of a matrix (4). The stop has a free branch (8) partially supported at surface of the matrix before projecting inside an opening (5) of the matrix to arrange a support zone forming the stop for break-off pieces (2) to be separated, where the branch (8) has an end in V shape. An independent claim is also included for an assembly comprising a stationary stop and a matrix to equip a break-off pieces elimination device.</p> |
